XmTextField
NAME
XmTextField - The TextField class
SYNOPSIS
#include <Xm/TextF.h>
DESCRIPTION
TextField widget provides a single line text editor for customizing
both user and programmatic interfaces. It is used for single-line
string entry, and forms entry with verification procedures. It
provides an application with a consistent editing system for textual
data.
TextField widget 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 actions. The key bindings
have been added for insert cursor movement, deletion, insertion, and
selection of text.
TextField allows the user to select regions of text. Selection is
based on the model specified in the Inter-Client Communication
Conventions Manual (ICCCM). TextField supports primary and
secondary selection.
Classes
TextField widget inherits behavior and resources from Core and Primitive
classes.
The class pointer is xmTextFieldWidgetClass.
The class name is XmTextField.
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
lower case or upper case, 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).
- XmNactivateCallback
- Specifies the list of callbacks that is called when the user
invokes an event that calls the Activate() function.
The type of the structure whose address is passed to this callback is
XmAnyCallbackStruct. The reason sent by the callback
is XmCR_ACTIVATE.
- XmNblinkRate
- Specifies the blink rate of the text cursor in milliseconds.
The time indicated in the blink rate relates to the length of time the
cursor is visible and the time the cursor is invisible (i.e., the time
it will take to blink the insertion cursor on and off will be 2 times
the blink rate). The cursor will not blink when the blink rate is set
to 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 maximum character width
of the associated font. 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. The default value
depends on the value of the XmNwidth resource. If no
width is specified the default is 20.
- 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.
- XmNcursorPositionVisible
- Indicates that the insert cursor position is marked by a
blinking text cursor when the Boolean is True.
- XmNeditable
- Indicates that the user can edit the text string when set to
True. A false value will prohibit the user from editing the text.
- XmNfocusCallback
- Specifies the list of callbacks called when TextField 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.
- XmNfontList
- Specifies the font list to be used for TextField. If this value
is NULL at initialization, it is initialized by looking up the parent
hierarchy of the widget for an ancestor that is a subclass of the XmBulletinBoard or VendorShell widget class. If such an
ancestor is found, the font list is initialized to the XmNtextFontList
of the ancestor widget. If no such ancestor is found, the default is
implementation dependent. Refer to XmFontList(3X) for more
information on a font list structure.
TextField searches the font list for the first occurrence of a font
set that has a 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 is
used.
- XmNgainPrimaryCallback
- Specifies the list of callbacks that are called when the user
invokes an event that cause the text widget to gain ownership of the
primary selection. The callback reason for this callback is
XmCR_GAIN_PRIMARY.
- XmNlosePrimaryCallback
- Specifies the list of callbacks that are called when the user
invokes an event that cause the text widget to lose ownership of the
primary selection. The callback reason for this callback is
XmCR_LOSE_PRIMARY.
- XmNlosingFocusCallback
- Specifies the list of callbacks that is called before TextField
widget 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 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 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 non-negative.
Strings that are entered using the XmNvalue resource
or the XmTextFieldSetString function
ignore this resource.
- XmNmodifyVerifyCallback
- Specifies the list of callbacks that is called before text is
deleted from or inserted into TextField. 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
TextField widgets share the same source, only the widget that
initiates the source change will generate the
XmNmodifyVerifyCallback.
If both XmNmodifyVerifyCallback and XmNmodifyVerifyCallbackWcs
are registered callback lists, the procedure(s) in the
XmNmodifyVerifyCallback list are 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
TextField 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 are 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 that is 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 more than one XmNmotionVerifyCallbacks to be
generated from a single action.
- XmNpendingDelete
- Indicates that pending delete mode is on when the Boolean is
True. Pending deletion is defined as deletion of the selected text
when an insertion is made.
- XmNresizeWidth
- Indicates that TextField widget will attempt to resize its
width to accommodate all the text contained in the widget when Boolean
is True.
- XmNselectionArray
- Defines the actions for multiple-mouse clicks. Each mouse click
performed within a half of a second of the previous mouse click will
increment the index into this array and perform the defined action for
that index. The possible actions are:
- XmSELECT_POSITION - resets the insert cursor
position.
- XmSELECT_WORD - selects a word.
- XmSELECT_LINE - selects a line of text.
- XmNselectionArrayCount
- Specifies the number of actions that are defined 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.
- XmNvalue
- Specifies the string value of the TextField widget as a
char* data value. 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 that is called after text is
deleted from or inserted into TextField. 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 TextField
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 TextField, not in the TextField
widget. The XmNvalueChangedCallback should occur only
in pairs with a 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 TextField widget as a
wchar_t* data value. 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 a bell will sound when an action is reversed
during a verification callback. The default depends on the value of
the ancestor VendorShell's
XmNaudibleWarning
resource.
Inherited Resources
TextField widget inherits behavior and resources from the following
superclasses. For a complete description of these resources, refer to
the man page for that superclass.
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 TextField widget defines a new callback structure for use with
verification callbacks. Note that not all of the 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 upon
receiving the callback, and these changes will be reflected as the
change made to the source of the TextField widget. (For example, all
keystrokes can be converted to spaces or NULL characters when a
password is entered into a TextField 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 the callbacks for
XmNlosingFocusCallback,
XmNmodifyVerifyCallback, and
XmNmotionVerifyCallback.
typedef struct
{
int reason;
XEvent *event;
Boolean doit;
XmTextPosition currInsert, newInsert;
XmTextPosition startPos, endPos;
XmTextBlock text;
} XmTextVerifyCallbackStruct, *XmTextVerifyPtr;
- reason
- Indicates why the callback was invoked.
- event
- 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 that action that invoked the callback will be
performed. Setting doit to False negates the action.
- 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, then 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.
typedef struct
{
char *ptr;
int length;
XmTextFormat format
} XmTextBlockRec, *XmTextBlock;
- ptr
- Is the text to be inserted. ptr points to a temporary
storage space that is reused after the callback is
finished. Therefore, if an application needs to save the text to be
inserted, it should copy the text into its own data space.
- length
- Specifies the length of the text to be inserted.
- format
- Specifies the format of the text, either
XmFMT_8_BIT or XmFMT_16_BIT.
A pointer to the following structure is passed to callbacks for
XmNmodifyVerifyCallbackWcs.
typedef struct
{
int reason;
XEvent *event;
Boolean doit;
XmTextPosition currInsert, newInsert;
XmTextPosition startPos, endPos;
XmWcsTextBlock text;
} XmTextVerifyCallbackStructWcs, *XmTextVerifyPtrWcs;
- reason
- Indicates why the callback was invoked.
- event
- 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.
- 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
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:
Reason Valid Fields
XmCR_LOSING_FOCUS reason, event, doit
XmCR_MODIFYING_TEXT_VALUE reason, event, doit, currInsert, newInsert, startPos, endPos, text
XmCR_MOVING_INSERT_CURSOR reason, event, doit, currInsert, newInsert

Action Routines
The XmText action routines are described below:
- activate():
- Calls the callbacks for XmNactivateCallback.
If the parent is a manager, passes the event to the parent.
- backward-character():
-
Moves the insertion cursor one character to the left.
For other effects, see the description of navigation operations in the
"Keyboard Selection" section in XmText(3X).
This action may have different behavior in a right-to-left language
environment.
- backward-word(extend):
- If this action is called with no argument, moves the insertion
cursor to the first non-whitespace character after the first
whitespace character to the left or after the beginning of the line.
If the insertion cursor is already at the beginning of a word, moves
the insertion cursor to the beginning of the previous word. For other
effects, see the description of navigation operations in the "Keyboard
Selection" section in XmText(3X). This action may have
different behavior in a locale other than the C locale.
If called with an argument of extend, moves the
insertion cursor as in the case of no argument and extends the current
selection. For other effects, see the description of shifted
navigation operations in the "Keyboard Selection" section in
XmText(3X).
- beginning-of-line(extend):
- If this action is called with no argument, moves the insertion
cursor to the beginning of the line. For other effects, see the
description of navigation operations in the "Keyboard Selection"
section in XmText(3X).
If called with an argument of extend, moves the
insertion cursor as in the case of no argument and extends the current
selection. For other effects, see the description of shifted
navigation operations in the "Keyboard Selection" section in
XmText(3X).
- clear-selection():
- Clears the current selection by replacing each character except
<Return> with a <Space> character.
- copy-clipboard():
- Copies the current selection to the clipboard.
- copy-primary():
- Copies the primary selection to just before the insertion
cursor.
- copy-to():
- If a secondary selection exists, copies the secondary selection
to just before the insertion cursor. If no secondary selection
exists, copies the primary selection to the pointer location.
- cut-clipboard():
- Cuts the current selection to the clipboard.
- cut-primary():
- Cuts the primary selection to just before the insertion cursor.
- delete-next-character():
- In normal mode if there is a non-null selection, deletes the
selection, otherwise deletes the character following the insertion
cursor. In add mode if there is a non-null selection, the cursor is
not disjoint from the selection and XmNpendingDelete
is set to True, deletes the selection, otherwise deletes the character
following the insertion cursor. This may impact the selection.
- delete-next-word():
- In normal mode if there is a non-null selection, deletes the
selection, otherwise deletes the characters following the insertion
cursor to the next space, tab or end of line character. In add mode
if there is a non-null selection, the cursor is not disjoint from the
selection and XmNpendingDelete is set to True,
deletes the selection, otherwise deletes the characters following the
insertion cursor to the next space, tab or end of line character.
This may impact the selection. This action may have different
behavior in a locale other than the C locale.
- delete-previous-character():
- In normal mode if there is a non-null selection, deletes the
selection, otherwise deletes the character of text immediately
preceding the insertion cursor. In add mode if there is a non-null
selection, the cursor is not disjoint from the selection and
XmNpendingDelete is set to True, deletes the
selection, otherwise deletes the character of text immediately
preceding the insertion cursor. This may impact the selection.
- delete-previous-word():
- In normal mode if there is a non-null selection, deletes the
selection, otherwise deletes the characters preceding the insertion
cursor to the next space, tab or beginning of the line character. In
add mode if there is a non-null selection, the cursor is not disjoint
from the selection and XmNpendingDelete is set to
True, deletes the selection, otherwise deletes the characters
preceding the insertion cursor to the next space, tab or beginning of
line character.. This may impact the selection. This action may have
different behavior in a locale other than the C locale.
- delete-selection():
- Deletes the current selection.
- delete-to-end-of-line():
- In normal mode if there is a non-null selection, deletes the
selection, otherwise deletes the characters following the insertion
cursor to the next end of line character. In add mode if there is a
non-null selection, the cursor is not disjoint from the selection and
XmNpendingDelete is set to True, deletes the
selection, otherwise deletes the characters following the insertion
cursor to the next end of line character. This may impact the
selection.
- delete-to-start-of-line():
- In normal mode if there is a non-null selection, deletes the
selection, otherwise deletes the characters preceding the insertion
cursor to the previous beginning of line character. In add mode if
there is a non-null selection, the cursor is not disjoint from the
selection and XmNpendingDelete is set to True,
deletes the selection, otherwise deletes the characters preceding the
insertion cursor to the previous beginning of line character. This
may impact the selection.
- deselect-all():
- Deselects the current selection.
- end-of-line(extend):
- If this action is called with no argument, moves the insertion
cursor to the end of the line. For other effects, see the description
of navigation operations in the "Keyboard Selection" section in
XmText(3X). If called
with an argument of extend, moves the insertion
cursor as in the case of no argument and extends the current
selection. For other effects, see the description of shifted
navigation operations in the "Keyboard Selection" section in
XmText(3X).
- extend-adjust():
- Selects text from the anchor to the pointer position and
deselects text outside that range.
- extend-end():
- Moves the insertion cursor to the position of the pointer.
- extend-start():
- Adjusts the anchor using the balance-beam method. Selects text
from the anchor to the pointer position and deselects text outside
that range.
- forward-character():
- Moves the insertion cursor one character to the right. For
other effects, see the description of navigation operations in the
"Keyboard Selection" section in XmText(3X). This action may have
different behavior in a right-to-left language environment.
- forward-word(extend):
- If this action is called with no argument, moves the insertion
cursor to the first whitespace character or end of line following the
next non-whitespace character. If the insertion cursor is already at
the end of a word, moves the insertion cursor to the end of the next
word. For other effects, see the description of navigation operations
in the "Keyboard Selection" section in XmText(3X). This action may have
different behavior in a locale other than the C locale.
If called with an argument of extend, moves the
insertion cursor as in the case of no argument and extends the current
selection. For other effects, see the description of shifted
navigation operations in the "Keyboard Selection" section in
XmText(3X).
- grab-focus():
- This key binding performs the action defined in the
XmNselectionArray, depending on the number of
multiple mouse clicks. The default selection array ordering is one
click to move the insertion cursor to the pointer position, two clicks
to select a word, three clicks to select a line of text, and four
clicks to select all text. A single click also deselects any selected
text and sets the anchor at the pointer position. This action may
have different behavior in a locale other than the C locale.
- Help():
- Calls the callbacks for XmNhelpCallback
if any exist. If there are no help callbacks for this widget, this
action calls the help callbacks for the nearest ancestor that has
them.
- key-select(direction):
- If called with an argument of right, moves the
insertion cursor one character to the right and extends the current
selection. If called with an argument of left, moves
the insertion cursor one character to the left and extends the current
selection. If called with no argument, extends the current selection.
For other effects, see the description of shifted navigation
operations and KExtend" in the "Keyboard Selection"
section in XmText(3X).
- move-destination():
- Moves the insertion cursor to the pointer position without
changing any existing current selection. If there is no current
selection, sets the widget as the destination widget.
- move-to():
- If a secondary selection exists, cuts the secondary selection
to just before the insertion cursor. If no secondary selection
exists, cuts the primary selection to the pointer location.
- next-tab-group():
- Traverses to the next tab group.
- page-left():
- Scrolls the viewing window left one page of text.
- page-right():
- Scrolls the viewing window right one page of text.
- paste-clipboard():
- Pastes the contents of the clipboard before the insertion
cursor.
- prev-tab-group():
- Traverses to the previous tab group.
- process-bdrag()
- The result of this action is determined by several factors:
position of the location cursor, movement of the location cursor, and
the interval between a BDrag press and release.
This action copies the current selection to the insertion cursor if
text is selected, the location cursor is disjoint from the selection,
and no motion is detected within a given time interval.
It performs a secondary selection and copies the selection to the
position where the text was last edited if the cursor is disjoint from
a current selection (if one exists), the time interval is exceeded,
and movement of the location cursor is detected.
The action drags the current selection if the location cursor is
positioned on the selection, the time interval is exceeded, and
movement of the location cursor is detected. This action creates a
DragContext object whose XmNexportTargets
resource value includes target types of COMPOUND_TEXT, STRING, and
TEXT.
- process-cancel():
- Cancels the current extend-adjust(),
secondary-adjust() or process-bdrag
operation and leaves the selection state as it was before the
operation, otherwise, and the parent is a manager, it passes the event
to the parent.
- secondary-adjust():
- Extends the secondary selection to the pointer position.
- secondary-start():
- Marks the beginning of a secondary selection.
- select-all():
- Selects all text.
- self-insert():
- If XmNpendingDelete is True and the cursor is
not disjoint from the current selection, deletes the entire selection.
Inserts the character associated with the key pressed before the
insertion cursor.
- set-anchor():
- Resets the anchor point for extended selections. Resets the
destination of secondary selection actions.
- toggle-add-mode():
- Toggles the state of Add Mode.
- toggle-overstrike():
- Toggles the state of the text insertion mode. By default,
characters typed into the TextField widget are inserted before the
position of the insertion cursor. In overstrike mode, characters
entered into the TextField widget replace the characters that directly
follow the insertion cursor. In overstrike mode, when the end of a
line is reached, characters are appended to the end of the line.
- traverse-home():
- Traverses to the first widget in the tab group.
- traverse-next():
- Traverses to the next widget in the tab group.
- traverse-prev():
- Traverses to the previous widget in the tab group.
Additional Behavior
This widget has the additional behavior described below:
- <FocusIn>:
- Draws the insertion cursor as solid and starts blinking the
cursor.
- <FocusOut>:
- Displays the insertion cursor as a stippled I-beam unless it is
the destination widget.
