Text provides a single-line and multiline text editor for customizing both user and
programmatic interfaces. It can be used for single-line string entry,
forms entry with verification procedures, and full-window editing.
It provides an application with a consistent editing system for
textual data. The screen's textual data adjusts to the
application writer's needs.
Text provides separate callback lists to verify
movement of the insert cursor, modification of the text, and
changes in input focus. Each of
these callbacks provides the verification function with the
widget instance, the event that caused the callback, and a
data structure specific to the verification type. From this
information, the function can verify if the application considers
this to be a legitimate state change and can signal the widget
whether to continue with the action.
The user interface tailors a new set of translations. The default
translations provide key bindings for insert cursor movement, deletion,
insertion, and selection of text.
Text allows the user to select regions of text.
Selection is based on the model specified in the Inter-Client
Communication Conventions Manual (ICCCM). Text supports primary
and secondary selection.
In some Asian languages, texts are drawn vertically. Also, some characters
are displayed with 90-degree clockwise rotation, and other characters are mapped
to vertical glyphs that differ from the normal horizaontal
glyphs.
Information about which characters require rotation or
mapping to vertical glyphs is specified in the X Locale Database (NLS
databases) and handled by X library, depending on
XNOrientationXOC values.
XmText widget should also handle the vertically aligned
lines as for editing, entering, or selecting texts.
The vertical writing feature of the XmText widget is enabled when the
XmTOP_TO_BOTTOM value is specified for the XmNlayoutDirection
resource of the XmText widget. In that case, the horizontal scroll
bar is displayed on the bottom of the XmText widget and the vertical
scroll bar is displayed on the left side.
Mouse Selection
The Text widget allows text to be edited, inserted, and selected.
The user can cut, copy, and paste text by using the clipboard, primary
transfer, or secondary transfer.
Text also provides a Drag and Drop facility that enables the user to
copy or move data within Text or to a different widget.
When
keyboard focus policy is set to EXPLICIT, the widget that receives
focus is the destination widget. In POINTER mode, any keyboard
or mouse operation (except secondary selection) in an
editable widget establishes that widget as the destination.
If a destination widget becomes insensitive or uneditable, it forfeits
its destination status. In EXPLICIT mode, when a widget becomes
insensitive, the focus moves to another widget. If that widget
is editable, it becomes the destination widget; otherwise, there
is no destination widget. The text of any insensitive Text widget
is stippled, indicating its state to the user.
The insertion cursor, displayed as an I-beam, shows where input is
inserted. Input is inserted just before the insertion cursor.
Text uses the XmQTnavigator, XmQTspecifyRenderTable, and
XmQTscrollFrame traits,
and holds the XmQTaccessTextual
and XmQTtransfer traits.
The widget checks its parent for the XmQTscrollFrame trait. If this
trait does not exist, then the widget has no scrolling. If the trait
does exist, and the ScrollFrame widget has not been initialized, the widget
creates two navigators and sets up the scrollbars.
If an application or widget calls the setValue trait method
of XmQTaccessTextual, then XmText will call
XmTextSetString to set the string value.
Classes
Text inherits behavior, resources, and traits from Core and
XmPrimitive.
The class pointer is xmTextWidgetClass.
The class name is XmText.
Data Transfer Behavior
Text supports transfer of the primary, secondary, and clipboard
selections and dragging of selected text from the widget.
Text can also be the destination for the primary, secondary, and
clipboard selections, and it supports dropping of data being dragged
onto the widget.
When the XmNconvertCallback procedures are called, the
location_data member of the XmConvertCallbackStruct member
is NULL if the selected text is being transferred.
If the entire text, not the selected text, is being transferred, the
value of this member is the widget ID of the Text widget.
As a source of data, Text supports the following targets and associated
conversions of data to these targets:
locale
If the locale target matches the widget's locale, the widget
transfers the selected text in the encoding of the locale.
COMPOUND_TEXT
The widget transfers the selected text as type COMPOUND_TEXT.
STRING
The widget transfers the selected text as type STRING.
TEXT
If the selected text is fully convertible to the encoding of the locale,
the widget transfers the selected text in the encoding of the locale.
Otherwise, the widget transfers the selected text as type
COMPOUND_TEXT.
UTF8_STRING
The widget transfers the selected text as type UTF8_STRING.
DELETE
The widget deletes the selected text.
_MOTIF_CLIPBOARD_TARGETS
The widget transfers, as type ATOM, a list of the targets to which
the widget can convert data to be placed on the clipboard immediately.
If the selected text is fully convertible to STRING, these include
STRING; otherwise, they include COMPOUND_TEXT.
_MOTIF_DEFERRED_CLIPBOARD_TARGETS
The widget transfers, as type ATOM, a list of the targets it
supports for delayed transfer for the CLIPBOARD selection.
This widget currently supplies no targets for
_MOTIF_DEFERRED_CLIPBOARD_TARGETS.
_MOTIF_EXPORT_TARGETS
The widget transfers, as type ATOM, a list of the targets to be
used as the value of the DragContext's XmNexportTargets in a
drag-and-drop transfer.
These include COMPOUND_TEXT, UTF8_STRING,
the encoding of the locale,
STRING, TEXT, BACKGROUND, and FOREGROUND.
_MOTIF_LOSE_SELECTION
The widget takes the following actions:
•
When losing the PRIMARY selection, it unhighlights the selected
text and calls the XmNlosePrimaryCallback procedures.
•
When losing the SECONDARY selection, it removes the secondary
selection highlight.
•
When losing the _MOTIF_DESTINATION selection, if the widget does
not have focus, it changes the cursor to indicate that the widget is no
longer the destination.
As a source of data, Text also supports the following standard Motif
targets:
BACKGROUND
The widget transfers XmNbackground as type PIXEL.
CLASS
The widget finds the first shell in the widget hierarchy that has a
WM_CLASS property and transfers the contents as text in the
current locale.
CLIENT_WINDOW
The widget finds the first shell in the widget hierarchy and transfers
its window as type WINDOW.
COLORMAP
The widget transfers XmNcolormap as type COLORMAP.
FOREGROUND
The widget transfers XmNforeground as type PIXEL.
NAME
The widget finds the first shell in the widget hierarchy that has a
WM_NAME property and transfers the contents as text in the current
locale.
TARGETS
The widget transfers, as type ATOM, a list of the targets it
supports.
These include the standard targets in this list.
These also include COMPOUND_TEXT, UTF8_STRING,
the encoding of the locale, STRING, and TEXT.
TIMESTAMP
The widget transfers the timestamp used to acquire the selection as type
INTEGER.
_MOTIF_RENDER_TABLE
The widget transfers XmNrenderTable if it exists, or else the
default text render table, as type STRING.
_MOTIF_ENCODING_REGISTRY
The widget transfers its encoding registry as type STRING.
The value is a list of NULL separated items in the
form of tag encoding pairs.
This target symbolizes the transfer target for the
Motif Segment Encoding Registry.
Widgets and applications can use this Registry to register
text encoding formats for specified render table tags.
Applications access this Registry by calling
XmRegisterSegmentEncoding and XmMapSegmentEncoding.
As a destination for data, Text chooses a target and requests conversion
of the selection to that target.
If the encoding of the locale is present in the list of available
targets, Text chooses a requested target from the available targets in
the following order of preference:
1.
The encoding of the locale
2.
TEXT
4.
UTF8_STRING
3.
COMPOUND_TEXT
4.
STRING
If the encoding of the locale is not present in the list of available
targets, Text chooses a requested target from the available targets in
the following order of preference:
4.
UTF8_STRING
1.
COMPOUND_TEXT
2.
STRING
New Resources
The following table defines a set of widget resources used by the programmer
to specify data. The programmer can also set the resource values for the
inherited classes to set attributes for this widget. To reference a
resource by name or by class in a .Xdefaults file, remove the XmN or
XmC prefix and use the remaining letters. To specify one of the defined
values for a resource in a .Xdefaults file, remove the Xm prefix and use
the remaining letters (in either lowercase or uppercase, but include any
underscores between words).
The codes in the access column indicate if the given resource can be
set at creation time (C),
set by using XtSetValues (S),
retrieved by using XtGetValues (G), or is not applicable (N/A).

1 This resource cannot be set in a resource file.
XmNactivateCallback
Specifies the list of callbacks that is called when the user invokes an
event that calls the
activate() action.
The type of the structure whose address is passed to this callback is
XmAnyCallbackStruct.
The reason sent by the callback is XmCR_ACTIVATE.
XmNautoShowCursorPosition
Ensures that the visible text contains the insert cursor when set
to True.
If the insert cursor changes, the contents
of Text may scroll in order to bring the insertion
point into the window.
Setting this resource to False, however, does not ensure that Text
will not scroll.
XmNcursorPosition
Indicates the position in the text where the current insert cursor is to
be located.
Position is determined by the number of characters from the beginning of
the text.
The first character position is 0 (zero).
XmNcursorPositionVisible
If the widget has an XmPrintShell as one of its ancestors, then the
default value is False; otherwise, it is True.
XmNdestinationCallback
Specifies a list of callbacks called when the widget is the destination
of a transfer operation.
The type of the structure whose address is passed to these callbacks is
XmDestinationCallbackStruct.
The reason is XmCR_OK.
XmNeditable
When set to True, indicates that the user can edit the text string.
Prohibits the user from editing the text when set to False.
When XmNeditable is used on a widget
it sets the dropsite to XmDROP_SITE_ACTIVE.
XmNeditMode
Specifies the set of keyboard bindings used in Text.
The default, XmSINGLE_LINE_EDIT,
provides the set of key bindings to be used in editing
single-line text.
XmMULTI_LINE_EDIT provides the set of key bindings to be
used in editing multiline text.
The results of placing a Text widget inside a ScrolledWindow when the
Text's XmNeditMode is XmSINGLE_LINE_EDIT are undefined.
XmNfocusCallback
Specifies the list of callbacks called
when Text accepts input focus. The type of the structure whose
address is passed to this callback is XmAnyCallbackStruct.
The reason sent by the callback is XmCR_FOCUS.
XmNgainPrimaryCallback
Specifies the list of callbacks called when an event causes the Text
widget to gain ownership of the primary selection.
The reason sent by the callback is XmCR_GAIN_PRIMARY.
XmNlosePrimaryCallback
Specifies the list of callbacks called when an event causes the Text
widget to lose ownership of the primary selection.
The reason sent by the callback is XmCR_LOSE_PRIMARY.
XmNlosingFocusCallback
Specifies the list of callbacks called
before Text loses input focus.
The type of the structure whose address is passed to this callback is
XmTextVerifyCallbackStruct.
The reason sent by the callback is XmCR_LOSING_FOCUS.
XmNmarginHeight
Specifies the distance between the top edge of the widget
window and the text, and between the bottom edge of the widget
window and the text.
XmNmarginWidth
Specifies the distance between the left edge of the widget
window and the text, and between the right edge of the widget
window and the text.
XmNmaxLength
Specifies the maximum length of the text string that can be entered into
text from the keyboard. This value must be nonnegative.
Strings that are entered by using the XmNvalue resource or the
XmTextSetString function ignore this resource.
XmNmodifyVerifyCallback
Specifies the list of callbacks called
before text is deleted from or inserted into Text.
The type of the structure whose address is passed to this callback is
XmTextVerifyCallbackStruct.
The reason sent by the callback is XmCR_MODIFYING_TEXT_VALUE.
When multiple Text widgets share the same
source, only the widget that initiates the source change will
generate XmNmodifyVerifyCallback.
If both XmNmodifyVerifyCallback and XmNmodifyVerifyCallbackWcs
are registered callback lists, the procedure(s) in the
XmNmodifyVerifyCallback list is always executed first; and the
resulting data, which may have been modified, is passed to the
XmNmodifyVerifyCallbackWcs callback routines.
XmNmodifyVerifyCallbackWcs
Specifies the list of callbacks called before text is deleted from
or inserted into Text. The type of the structure whose address is
passed to this callback is XmTextVerifyCallbackStructWcs. The
reason sent by the callback is XmCR_MODIFYING_TEXT_VALUE.
When multiple Text widgets share the same
source, only the widget that initiates the source change will
generate the XmNmodifyVerifyCallbackWcs.
If both XmNmodifyVerifyCallback and XmNmodifyVerifyCallbackWcs
are registered callback lists, the procedure(s) in the
XmNmodifyVerifyCallback list is always executed first; and the
resulting data, which may have been modified, is passed to the
XmNmodifyVerifyCallbackWcs callback routines.
XmNmotionVerifyCallback
Specifies the list of callbacks called
before the insert cursor is moved to a new position.
The type of the structure whose address is passed to this callback is
XmTextVerifyCallbackStruct.
The reason sent by the callback is XmCR_MOVING_INSERT_CURSOR.
It is possible for more than one XmNmotionVerifyCallback to
be generated from a single action.
XmNsource
Specifies the source with which the widget displays text.
If no source is specified, the widget creates a default string source.
This resource can be used to share text sources between Text widgets.
XmNtopCharacter
Displays the position of text at the top of the window.
Position is determined by the number of characters from the
beginning of the text.
The first character position is 0 (zero).
If the XmNeditMode is XmMULTI_LINE_EDIT, the line of text
that contains the top character is displayed at the top of the widget
without shifting the text left or right.
XtGetValues for XmNtopCharacter returns the position of the
first character in the line that is displayed at the top of the widget.
XmNtotalLines
Indicates the number of lines in the text widget buffer (not necessarily
visible). The initial value 1 means the text buffer is empty. The number
of lines reported takes into account the wordWrap policy
(that is, it's not simply the number of newline characters.
XmNvalue
Specifies the string value of the Text widget as a char*
data value.
Moves the cursor to position 0 unless a value of
XmNcursorPosition was explicitly supplied in the argument list.
If XmNvalue and XmNvalueWcs are both
defined, the value of XmNvalueWcs supersedes that of
XmNvalue. XtGetValues returns a copy of the value of
the internal buffer and XtSetValues copies the string values
into the internal buffer.
XmNvalueChangedCallback
Specifies the list of callbacks called
after text is deleted from or inserted into
Text.
The type of the structure whose address is passed to this callback is
XmAnyCallbackStruct.
The reason sent by the callback is XmCR_VALUE_CHANGED.
When multiple Text widgets share the same
source, only the widget that initiates the source change will
generate the XmNvalueChangedCallback. This callback represents a
change in the source in the Text, not in the Text
widget. The XmNvalueChangedCallback should occur only in pairs
with an XmNmodifyVerifyCallback, assuming that the doit
flag in the callback structure of the XmNmodifyVerifyCallback is
not set to False.
XmNvalueWcs
Specifies the string value of the Text widget as a wchar_t* data
value.
Moves the cursor to position 0 unless a value of
XmNcursorPosition was explicitly supplied in the argument list.
This resource cannot be specified in a resource file.
If XmNvalue and XmNvalueWcs are both defined,
the value of XmNvalueWcs supersedes that of XmNvalue.
XtGetValues returns a copy of the value of the internal buffer
encoded as a wide character string. XtSetValues copies the
value of the wide character string into the internal buffer.
XmNverifyBell
Specifies whether the bell should sound when the verification returns
without continuing the action.
The default depends on the value of the ancestor VendorShell's
XmNaudibleWarning resource.

XmNpendingDelete
Indicates that pending delete mode is on when the Boolean value is True.
Pending deletion is defined as deletion
of the selected text when an insertion is made.
XmNselectionArray
Defines the actions for multiple mouse clicks. The value of the
resource is an array of XmTextScanType elements.
XmTextScanType is an enumeration indicating possible actions.
Each mouse click performed within some time of the previous mouse
click increments the index into this array and performs the defined
action for that index. (This "multiclick" time is specified by the
operating environment, and varies among different systems. In general,
it is usually set to some fraction of a second.) The possible actions
in the order they occur in the default array are as follows:
3.
XmSELECT_POSITION, which
resets the insert cursor position.
4.
XmSELECT_WORD, which
selects a word.
5.
XmSELECT_LINE, which
selects a line of text. This action sees a line as delimited by
hard newline characters. In other words, if the word wrap
feature is on (XmNwordWrap is True), this will ignore the
newlines automatically inserted by the widget. This is the default.
6.
XmSELECT_OUT_LINE, which
selects a line of text. This action sees a line as delimited by
hard or soft newline characters. In other words, if the
word wrap feature is on (XmNwordWrap is True), the newlines
automatically inserted by the widget will be treated as delimiting
lines.
7.
XmSELECT_ALL, which
selects all of the text.
XmNselectionArrayCount
Indicates the number of elements in the XmNselectionArray resource.
The value must not be negative.
XmNselectThreshold
Specifies the number of pixels of motion that is required to select the
next character when selection is performed using the click-drag
mode of selection.
The value must not be negative.
This resource also specifies whether a drag should be started and the
number of pixels to start a drag when
Btn2Down and Btn1Down are integrated.

XmNblinkRate
Specifies the blink rate of the text cursor in milliseconds.
The time indicated in the blink rate relates to the
time the cursor is visible and the time the
cursor is invisible (that is, the time it takes to blink
the insertion cursor on and off is twice the blink
rate). The cursor does not blink when the blink rate
is set to 0 (zero).
The value must not be negative.
XmNcolumns
Specifies the initial width of the text window as an integer number of
characters. The width equals the number of characters specified by
this resource multiplied by the width as derived from the specified
font. If the em-space
value is available,
it is used. If not, the width of the numeral "0" is used. If this is
not available, the maximum width is used.
For proportionate fonts, the actual number of characters that fit
on a given line may be greater than the value specified.
The value must be greater than 0 (zero). The default value depends
on the value of the XmNwidth resource.
If no width is specified the default is 20.
When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, and if the XmText
widget resource XmNeditMode is XmSINGLE_LINE_EDIT, this attribute is
ignored. If no width is specified, the default is 1.
XmNcursorPositionVisible
Indicates that the insert cursor position is marked by a text
cursor when the Boolean value is True.
XmNfontList
Specifies the font list to be used for Text. The font list is an
obsolete structure and is retained only for compatibility with
earlier releases of Motif. Use the render table (XmNrenderTable)
instead of font lists wherever possible. If both are specified, the
render table will take precedence. If this value is NULL at
initialization, the parent hierarchy of the widget is searched for an
ancestor that holds the XmQTspecifyRenderTable trait. If such
an ancestor is found, the font list is initialized to the
XmTEXT_RENDER_TABLE value of the ancestor widget. If no such
ancestor is found, the default is implementation dependent.
Text searches the font list for the first occurrence of a font set
that has XmFONTLIST_DEFAULT_TAG. If a default element is
not found, the first font set in the font list is used. If the
list contains no font sets, the first font in the font list will
be used. Refer to XmFontList(3) for
more information on a font list structure.
XmNrenderTable
Specifies the render table to be used in deriving a font set or font
for rendering text. If both a render table and a font list are
specified, the render table will take precedence. If the value of
XmNrenderTable is NULL at initialization, the parent hierarchy
of the widget is searched for an ancestor that holds the
XmQTspecifyRenderTable trait. If such an ancestor is found, the
font list is initialized to the XmTEXT_RENDER_TABLE value of the
ancestor widget. If no such ancestor is found, the default is
implementation dependent.
Text searches the render table for the first occurrence of a rendition
that has the tag _MOTIF_DEFAULT_LOCALE. If a default element is
not found, the first rendition in the table is used. Refer to
XmRenderTable(3) for more information on the render table
structure.
XmNresizeHeight
Indicates that Text will
attempt to resize its height to accommodate all the text
contained in the widget when the Boolean value is True. If the Boolean value is set to True,
the text is always
displayed, starting from the first position in the source, even if
instructed otherwise. This attribute is ignored when the application uses a
Text widget whose parent is a ScrolledWindow and when XmNscrollVertical is True.
When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this resource
indicates that the text attempts to resize its height to accommodate all the
text contained in the widget when the Boolean value is True. This attribute
is ignored if XmNwordWrap is True.
XmNresizeWidth
Indicates that Text attempts to resize its width to accommodate all
the text contained in the widget when the Boolean value is True.
This attribute is ignored if
XmNwordWrap is True.
When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this attribute
is still effective even if XmNwordWrap is True.
Also, this attribute is ignored when the application uses a text widget whose parent is
a ScrolledWindow and XmNscrollHorizaontal is True.
XmNrows
Specifies the initial height of the text window measured in character
heights. This attribute is ignored if the text widget resource
XmNeditMode is XmSINGLE_LINE_EDIT.
The value must be greater than 0 (zero).
The default value depends on the value of the XmNheight resource.
If no height is specified, the default is 1.
When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
attribute is still effective, even if the XmText widget resource
XmNeditMode is XmSINGLE_LINE_EDIT. If no height is specified,
the default is 20.
XmNwordWrap
Indicates that lines are to be broken at word breaks (that is, the text
does not go off the right edge of the window) when the Boolean value is True.
Words are defined as a sequence
of characters separated
by whitespace. Whitespace is defined as
a space, tab, or newline. This attribute is ignored if the text
widget resource XmNeditMode is XmSINGLE_LINE_EDIT.
Note that this resource is only valid when the widget is not a
scroll one, or, if the widget is a scroll widget, that the
XmNscrollHorizontal resource is False.
Indicates that lines are to be broken at word breaks (that is,
when the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, the text does not
go off the bottom edge of the window) when the Boolean value is True.
The following resources are used only when text is created in a
ScrolledWindow. See the reference page for XmCreateScrolledText.

XmNscrollHorizontal
Adds a ScrollBar that allows the user to scroll horizontally through
text when the Boolean value is True.
This resource is forced to False when the Text widget is placed in
a ScrolledWindow with XmNscrollingPolicy set to
XmAUTOMATIC.
When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
attribute is ignored if the XmText widget resource XmNeditMode
is XmSINGLE_LINE_EDIT.
XmNscrollLeftSide
Indicates that the vertical ScrollBar should be placed on the left side of
the scrolled text window when the Boolean value is True. This attribute
is ignored if XmNscrollVertical is False or the Text resource
XmNeditMode is XmSINGLE_LINE_EDIT.
When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
resource is still effective, even if the XmText widget resource
XmNeditMode is XmSINGLE_LINE_EDIT.
XmNscrollTopSide
Indicates that the horizontal ScrollBar should be placed on the top side of the
scrolled text window when the Boolean value is True.
When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
attribute is ignored if XmNscrollHorizontal is False
or the Xmtext resource
XmNeditMode is XmSINGLE_LINE_EDIT.
XmNscrollVertical
Adds a ScrollBar that allows the user to scroll vertically through text when
the Boolean value is True.
This attribute is ignored if the Text resource XmNeditMode is
XmSINGLE_LINE_EDIT.
This resource is forced to False when the Text widget is placed in
a ScrolledWindow with XmNscrollingPolicy set to
XmAUTOMATIC.
When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
resource is still effective, even if the XmText
widget resource XmNeditMode
is XmSINGLE_LINE_EDIT.

Callback Information
A pointer to the following structure is passed to each callback:
typedef struct
{
int reason;
XEvent * event;
} XmAnyCallbackStruct;
reason
Indicates why the callback was invoked
event
Points to the XEvent that triggered the callback
The Text widget defines a new callback structure
for use with verification callbacks. Note that
not all fields are relevant for every
callback reason. The application must first
look at the reason field and use only the structure
members that are valid for the particular reason.
The values startPos, endPos, and text in the
callback structure XmTextVerifyCallbackStruct may be modified
when the callback is received, and these changes will be reflected as
changes made to the source of the Text widget. (For example, all
keystrokes can be converted to spaces or NULL characters when a
password is entered into a Text widget.) The application
programmer should not overwrite the text field, but should
attach data to that pointer.
A pointer to the following structure is passed to callbacks for
XmNlosingFocusCallback, XmNmodifyVerifyCallback, and
XmNmotionVerifyCallback:
Points to the XEvent that triggered the callback.
It can be NULL. For example, changes made to the Text widget
programmatically do not have an event that can be
passed to the associated callback.
doit
Indicates whether the action that invoked the callback is performed.
Setting doit to False negates the action.
Note that not all actions may be negated. For example,
XmCR_LOSING_FOCUS callbacks may be beyond the control of the
widget if they are produced by mouse clicks.
currInsert
Indicates the current position of the insert cursor.
newInsert
Indicates the position at which the user attempts to position the insert
cursor.
startPos
Indicates the starting position of the text to modify. If the callback is
not a modify verification callback, this value is the same as currInsert.
endPos
Indicates the ending position of the text to modify. If no text is replaced or
deleted, the value is the same as startPos. If the callback is not
a modify verification callback, this value is the same as currInsert.
text
Points to a structure of type XmTextBlockRec. This structure holds
the textual information to be inserted.
Points to the XEvent that triggered the callback.
It can be NULL. For example, changes made to the Text widget
programmatically do not have an event that can be
passed to the associated callback.
doit
Indicates whether the action that invoked the callback is performed.
Setting doit to False negates the action.
Note that not all actions may be negated. For example,
XmCR_LOSING_FOCUS callbacks may be beyond the control of the
widget if they are produced by mouse clicks.
currInsert
Indicates the current position of the insert cursor.
newInsert
Indicates the position at which the user attempts to position the insert
cursor.
startPos
Indicates the starting position of the text to modify. If the callback is
not a modify verification callback, this value is the same as currInsert.
endPos
Indicates the ending position of the text to modify. If no text is replaced or
deleted, the value is the same as startPos. If the callback is not
a modify verification callback, this value is the same as currInsert.
text
Points to the following
structure of type XmTextBlockRecWcs. This structure holds
the textual information to be inserted.
typedef struct
{
wchar_t *wcsptr;
int length;
} XmTextBlockRecWcs, *XmTextBlockWcs;
wcsptr
Points to the wide character text to be inserted.
length
Specifies the number of characters to be inserted.
The following table describes the reasons for which the individual
verification callback structure fields are valid. Note that the
event field will never be valid for XmCR_MOVING_INSERT_CURSOR.
reason, event, doit, currInsert, newInsert, startPos, endPos, text
XmCR_MOVING_INSERT_CURSOR
reason, doit, currInsert, newInsert
A pointer to the following callback structure is passed to the
XmNdestinationCallback procedures:
typedef struct
{
int reason;
XEvent *event;
Atom selection;
XtEnum operation;
int flags;
XtPointer transfer_id;
XtPointer destination_data;
XtPointer location_data;
Time time;
} XmDestinationCallbackStruct;
reason
Indicates why the callback was invoked.
event
Points to the XEvent that triggered the callback.
It can be NULL.
selection
Indicates the selection for which data transfer is being requested.
Possible values are CLIPBOARD, PRIMARY, SECONDARY, and
_MOTIF_DROP.
operation
Indicates the type of transfer operation requested.
•
When the selection is PRIMARY or SECONDARY, possible
values are XmMOVE,
XmCOPY, and XmLINK.
•
When the selection is CLIPBOARD, possible
values are XmCOPY and XmLINK.
•
When the selection is _MOTIF_DROP, possible values are
XmMOVE, XmCOPY, XmLINK, and XmOTHER.
A value of XmOTHER means that the callback procedure must get
further information from the XmDropProcCallbackStruct structure in the
destination_data member.
flags
Indicates whether or not the destination widget is also the source of
the data to be transferred.
Following are the possible values:
XmCONVERTING_NONE
The destination widget is not the source of the data to be transferred.
XmCONVERTING_SAME
The destination widget is the source of the data to be transferred.
transfer_id
Serves as a unique ID to identify the transfer transaction.
destination_data
Contains information about the destination.
When the selection is _MOTIF_DROP, the callback procedures are
called by the drop site's XmNdropProc, and destination_data
is a pointer to the XmDropProcCallbackStruct structure passed to the
XmNdropProc procedure.
When the selection is SECONDARY,
destination_data
is an Atom
representing a target recommmended by the selection owner for use in
converting the selection.
Otherwise, destination_data is NULL.
location_data
Contains information about the location where data is to be transferred.
The value is always NULL when the selection is CLIPBOARD.
If the value is NULL, the data is to be inserted at the widget's cursor
position.
Otherwise, the value is a pointer to an XPoint structure
containing the x- and y- coordinates at the location where the data is to
be transferred. Once XmTransferDone procedures start to be called,
location_data will no longer be stable.
time
Indicates the time when the transfer operation began.
Translations
The XmText translations are described in the following list.
The actions represent the effective behavior of the associated events,
and they may differ in a right-to-left language environment.
The following key names are listed in the
X standard key event translation table syntax.
This format is the one used by Motif to
specify the widget actions corresponding to a given key.
A brief overview of the format is provided under
VirtualBindings(3).
For a complete description of the format, please refer to the
X Toolkit Instrinsics Documentation.

The Text button event translations are modified when Display's
XmNenableBtn1Transfer resource does not have a value of
XmOFF (in other words, it is either XmBUTTON2_TRANSFER or
XmBUTTON2_ADJUST). This
option allows the
actions for selection and transfer to be integrated on <Btn1>, and
the actions for extending the selection can be bound to
<Btn2>. The actions for <Btn1> that are defined above
still apply when the <Btn1> event occurs over text that is not
selected. The following actions apply when the <Btn1> event
occurs over text that is selected:
<Btn1Down>:
process-bdrag().
<Shift><Btn1Down>:
process-bdrag().
<Ctrl><Btn1Down>:
process-bdrag().
<Btn1Down><Shift><Btn1Up>:
grab-focus(), extend-end.
<Shift><Btn1Down><Shift><Btn1Up>:
extend-start(), extend-end().
<Ctrl><Btn1Down><Shift><Btn1Up>:
move-destination().
When Display's XmNenableBtn1Transfer resource has a value of
XmBUTTON2_ADJUST, the following actions apply:
<Btn2Down>:
extend-start().
<Btn2Motion>:
extend-adjust().
<Btn2Up>:
extend-end().
Action Routines
The XmText action routines are
activate():
Calls the callbacks for XmNactivateCallback.
Passes the event to the parent.
backward-character(extend):
Moves the insertion cursor one character to the left.
This action may have different behavior in a right-to-left language
environment.
If called with an argument of extend, moves the insertion cursor as
in the case of no argument and extends the current selection.
The backward-character() action produces calls to the
XmNmotionVerifyCallback procedures with reason value
XmCR_MOVING_INSERT_CURSOR.
If called with the extend argument, the
backward-character() action may produce calls to the
XmNgainPrimaryCallback procedures.

In vertical writing, if XmNeditMode is XmSINGLE_LINE_EDIT and
XmNnavigationType
is XmNONE, traverses to the widget to the left in the tab
group. If XmNeditMode is XmMULTI_LINE_EDIT, moves the insertion cursor
to the next line in the same column.
backward-paragraph(extend):
If XmNeditMode is XmMULTI_LINE_EDIT and this action is
called with no argument,
moves the insertion cursor to the first non-whitespace character following
the first previous blank line or beginning of the text.
If the insertion cursor is already at the beginning of a paragraph,
moves the insertion cursor to the beginning of the previous paragraph.
If XmNeditMode is XmMULTI_LINE_EDIT and this action is
called with an argument of extend, moves the insertion cursor as
in the case of no argument and extends the current selection.
The backward-paragraph() action produces calls to the
XmNmotionVerifyCallback procedures with reason value
XmCR_MOVING_INSERT_CURSOR.
If called with the extend argument, the
backward-paragraph() action may produce calls to the
XmNgainPrimaryCallback procedures.

XmCR_MODIFYING_TEXT_VALUE and the XmNvalueChangedCallback
procedures with reason value XmCR_VALUE_CHANGED.
copy-clipboard():
If this widget owns the primary selection, this action copies the
selection to the clipboard.
This action calls the XmNconvertCallback procedures, possibly
multiple times, for the CLIPBOARD selection.
copy-primary():
Copies the primary selection to just before the insertion cursor.
This action calls the XmNdestinationCallback procedures for the
PRIMARY selection and the XmCOPY operation.
It calls the selection owner's XmNconvertCallback procedures,
possibly multiple times, for the PRIMARY selection.
In addition, the copy-primary() action produces calls to the
XmNmodifyVerifyCallback procedures with reason value
XmCR_MODIFYING_TEXT_VALUE, to the XmNvalueChangedCallback
procedures with reason value XmCR_VALUE_CHANGED, and to the
XmNmotionVerifyCallback procedures with reason value

See callback description for more information.
cut-clipboard():
If this widget owns the primary selection, this action cuts the
selection to the clipboard.
This action calls the XmNconvertCallback procedures, possibly
multiple times, for the CLIPBOARD selection.
If the transfer is successful, this action then calls the
XmNconvertCallback procedures for the CLIPBOARD selection
and the DELETE target.
In addition, the cut-clipboard() action produces calls to the
XmNmodifyVerifyCallback procedures with reason value
XmCR_MODIFYING_TEXT_VALUE, and the XmNvalueChangedCallback
procedures with reason value XmCR_VALUE_CHANGED.

PRIMARY selection and the XmMOVE operation.
It calls the selection owner's XmNconvertCallback procedures,
possibly multiple times, for the PRIMARY selection.
If the transfer is successful, this action then calls the selection
owner's XmNconvertCallback procedures for the PRIMARY
selection and the DELETE target.
