NAME¶
XmComboBox — The ComboBox widget class "XmComboBox"
"widget class" "ComboBox"
SYNOPSIS¶
#include <Xm/ComboBox.h>
DESCRIPTION¶
XmComboBox combines the capabilities of a single-line TextField widget
and a List widget. It allows users to perform opoerations like typing and
pasting information, and it also provides a list of possible choices that the
user can select from to complete the TextField entry field. The list can
either be displayed at all times or can be dropped down by the user. When the
list portion of the ComboBox is hidden, users are given a visual cue (a
downward-pointing arrow) next to the TextField field. The position of the
arrow relative to the TextField field depends on the
XmNlayoutDirection
resource of the widget. This version of the ComboBox is called the
"drop-down" ComboBox. Drop-down ComboBoxes are useful when screen
space is limited, or when users will complete the text entry field more often
by typing text than by selecting the entry field text from the list. The user
can access the drop-down ComboBox in either one of two ways:
- •
- By clicking and releasing <Btn1> on the downward-pointing
arrow, which pops the list up, and the list stays up. A later selection of
an item in the list will cause the item to appear in the text entry field,
and the list will unpost itself.
- •
- By pressing <Btn1> on the downward-pointing arrow, dragging
it to a list item, and then releasing it there, which selects that item.
The list disappears, and the selected item appears in the text entry
field.
The application provides an array of strings that fill the list. At creation
time, string items can be passed to the ComboBox via an arglist. Each string
becomes an item in the list, with the first string becoming the item in
position 1, the second string becoming the item in position 2, and so on. The
size of the list is set by specifying the number of items that are visible in
the list (
XmNvisibleItemCount). If the number of items in the list
exceeds the number of items that are visible, a vertical scroll bar will
automatically appear that allows the user to scroll through a large number of
items.
ComboBox creates two child widgets: a TextField widget for entering text and a
ScrolledWindow containing a List for the list of items. The name of the items
list itself is
List, and the name of the TextField is
Text. The
application or user can specify resource values for these widgets in a
resource file, and the application can use
XtNameToWidget (specifying
"*List" for the items list or
"*Text" for
the TextField widget) to obtain the widget IDs of the descendant widgets. At
creation time, ComboBox passes appropriate resource values in the creation
arglist, including
XmNitems, to the items list. Note that the result of
providing the
XmNdestroyCallback resource in the creation
arglist is unspecified. The application should use the
XtAddCallback function to add callbacks to the appropriate widget
(TextField or List) after creating it.
ComboBox forces the following resource values on its List child:
- •
- If XmNcomboBoxType is XmCOMBO_BOX, XmNtraversalOn is
forced to False.
- •
- XmNhighlightThickness is forced to 2 in a drop-down ComboBox and to
0 in other types of ComboBoxes.
- •
- XmNborderWidth is forced to 0.
- •
- XmNnavigationType is forced to XmNONE.
- •
- XmNselectionPolicy is forced to XmBROWSE_SELECT.
- •
- XmNlistSizePolicy is forced to XmVARIABLE.
- •
- XmNspacing is forced to 0.
- •
- XmNvisualPolicy is forced to XmVARIABLE.
- •
- XmNselectedPositions is forced to NULL.
- •
- XmNselectedPositionsCount is forced to 0.
When
XmNcomboBoxType is
XmDROP_DOWN_LIST, ComboBox forces the
following resource values on its TextField child:
- •
- XmNeditable is forced to False.
- •
- XmNcursorPositionVisible is forced to False.
- •
- XmNshadowThickness is forced to 0.
By contrast, when
XmNcomboBoxType is
XmCOMBO_BOX or
XmDROP_DOWN_COMBO_BOX, ComboBox forces the following resource values on
its TextField child:
- •
- XmNeditable is forced to True.
- •
- XmNcursorPositionVisible is forced to True.
- •
- XmNeditMode is forced to XmSINGLE_LINE_EDIT.
ComboBox always forces the values of the following resources on the TextField:
- •
- XmNnavigationType is forced to XmNONE.
- •
- XmNhighlightThickness is forced to 0.
- •
- XmNborderWidth is forced to 0.
ComboBox allows a single item to be selected in two ways: by selecting the
desired item from the List or by entering text into the TextField. ComboBox
does not automatically select a list item if the user types that string into
the TextField. It selects the item when the user presses
KActivate or
moves the focus. ComboBox supports the Browse Select selection model of List
(see the
XmList reference page for a description of this model), so
selections are mutually exclusive. Selecting an item from the list causes that
item to be displayed in the TextField portion of the ComboBox. If an
application sets the
XmNvalue resource of TextField, that string is
shown in the TextField. If the application has not provided any list items, or
if there is no current selection, the TextField is empty.
The TextField in the ComboBox widget can be either editable or noneditable,
depending on the value of the
XmNcomboBoxType resource.
If the TextField is editable, the user can type into it. When the user presses
the Return key, the ComboBox will compare the typed entry to the items in the
List. If there is an exact match, then the matched List item is selected. If
the application wishes to validate the entered text (for example, to ensure
that the typed selection is a valid one), it can do so by setting
XmNmodifyVerifyCallback on the TextField widget.
If the TextField is noneditable, typing text may invoke a matching algorithm
that will attempt to match the entered text with items in the list. The
specific matching algorithm applied, which may be none, is determined by the
value of the
XmNmatchBehavior resource in ComboBox, which can be either
XmNONE or
XmQUICK_NAVIGATE. A value of
XmNONE indicates
that no matching algorithm will occur. A value of
XmQUICK_NAVIGATE
indicates that when the List widget has focus, one-character navigation is
supported. In this algorithm, if the typed character is the initial character
of some item in the List, this algorithm causes that item to be navigated to
and selected, and the item is displayed in the TextField. Subsequently typing
the same character will cycle among the items with the same first character.
Regardless of the selection mechanism used (either selected directly from the
List or typed into the TextField), when an item in the List is selected, that
item is highlighted in the List. In addition, the selected item is displayed
in the TextField of the ComboBox. If the user performs an action that would
move focus away from ComboBox, or selects a List item, the
XmNselectionCallback callbacks are invoked to notify the application of
the current contents of the TextField (or choice). The application then takes
whatever action is required based on those contents (or choice).
ComboBox uses the
XmQTspecifyRenderTable trait and holds the
XmQTaccessTextual trait.
Classes¶
XmComboBox inherits behavior, resources, and traits from
Core,
Composite, and
XmManager classes.
The class pointer is
xmComboBoxWidgetClass.
The class name is
XmComboBox.
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 at creation time (C), set by using
XtSetValues
(S), retrieved by using
XtGetValues (G), or is not applicable (N/A).

- XmNarrowSize
- Specifies the width of the arrow. The default size depends on the size of
the text, as well as the size of the ComboBox.
- XmNarrowSpacing
- Specifies the space between the text and arrow visual in pixels. The
default value is obtained from the XmNmarginWidth resource.
- XmNcolumns
- Specifies the number of columns in the text field. If unset, the text
field's value is used. Refer to the XmTextField man page for more
detailed information.
- XmNcomboBoxType
- Specifies the type of ComboBox to be created. This can be one of the
following:
- XmCOMBO_BOX
- Generates a ComboBox where the list is always displayed, and the text
entry field is editable.
- XmDROP_DOWN_COMBO_BOX
- Generates a ComboBox where the list is hidden unless specifically
requested, and the text entry field is editable.
- XmDROP_DOWN_LIST
- Generates a ComboBox where the list is hidden unless specifically
requested, and the text entry field is noneditable.
- XmNfontList
- Specifies the fontlist associated with XmComboBox. The fontlist is
an obsolete construct, and has been superseded by the render table. It is
included for compatibility with earlier versions of Motif, and for
applications that do not easily support render tables. The default
fontlist is derived from the default render table, and if both a fontlist
and a render table are specified, the render table takes precedence.
- XmNhighlightThickness
- Specifies the thickness of the highlighting rectangle.
- XmNitemCount
- Specifies the number of items in the list. If unset, the lists's value is
used. Refer to the XmList man page for more detailed
information.
- XmNitems
- Specifies the items in the list. If unset, the lists's value is used.
Refer to the XmList man page for more detailed information.
- XmNlist
- The list widget.
- XmNmarginWidth
- Specifies the horizontal spacing between the child widgets and the
boundary of the ComboBox.
- XmNmarginHeight
- Specifies the vertical spacing between the child widgets and the boundary
of the ComboBox.
- XmNmatchBehavior
- Defines the matching algorithm applied to match the text typed by the user
in the TextField field with items in the list. The current values are
XmNONE and XmQUICK_NAVIGATE, as follows:
- XmNONE
- Indicates that there is no assigned matching algorithm.
- XmQUICK_NAVIGATE
- Is only valid for noneditable ComboBoxes (XmNcomboBoxType resource
value XmDROP_DOWN_LIST). This algorithm supports 1-character
navigation when the List widget has focus. If the typed character is the
initial character of some item in the List, this algorithm causes that
item to be navigated to and selected. Subsequently typing the same
character will cycle among the items with the same first character.
- XmNpositionMode
- Specifies how the value of the XmNselectedPosition resource and the
item_position field of the callback structure are to be
interpreted. Note that the convenience functions
XmComboBoxDeletePos and XmComboBoxAddItem are not affected
by this resource, and (like XmList) always use 1-based positions.
Valid values for this resource are:
- XmZERO_BASED
- (DtComboBox compatibility mode: default) XmNselectedPosition is in
[0,itemcount-1]. The item_position in the
XmComboBoxCallbackStruct is 0 if the first element in the list was
selected. Note that 0 is also returned if no element in the list was
selected (that is, a new item was entered in the text field).
- XmONE_BASED
- (Motif mode) Both the resource value and the callback fields are 1-based.
This is consistent with other Motif widgets.
- XmNrenderTable
- Specifies the render table associated with ComboBox. This render table is
used in both the TextField field and the List in the ComboBox. This is
used in conjunction with the XmNvisibleItemCount resource of the
List to determine the height of the ComboBox widget.
-
- If this value is NULL at initialization, and if the widget parent is
XmBulletinBoard or its subclasses, VendorShell or its
subclasses, or XmMenuShell, then the widget parent provides the
default render table associated with the widget. If both a render table
and a fontlist are specified, the render table will take precedence.
- XmNselectedItem
- Specifies a compound string that represents the current selection of the
ComboBox. The selected item is the content of the ComboBox text entry
field.
- XmNselectedPosition
- If the selection in the ComboBox is an item in the list, this is the index
of the selected item in the list. If no item in the list is selected, this
is 0.
- XmNselectionCallback
- Specifies the list of callbacks called when an item is selected. The
reason field in the XmComboBoxCallbackStruct is
XmCR_SELECT.
- XmNtextField
- The text field widget.
- XmNvisibleItemCount
- Specifies the number of visible items in the list. This will override any
value specified for the list. Refer to the XmList man page for more
detailed information.

A pointer to the following structure is passed to each callback. The callback
structure is defined as follows:
typedef struct
{
int reason;
XEvent * event;
XmString item_or_text;
int item_position;
} XmComboBoxCallbackStruct;
- reason
- Indicates why the callback was invoked.
- event
- Points to the XEvent that triggered the callback. It can be
NULL.
- item_or_text
- The contents of the text field at the time the event caused the callback.
The item_or_text parameter points to a temporary storage space that
is reused after the callback is finished. If an application needs to save
the item, it should copy item_or_text into its own data space.
- item_position
- The position of item in the list's XmNitems 1-based array. If this
is 0, it means that the item_or_text was not selected from the
List.
Translations¶
The ComboBox translations are listed below.
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.
Note:
The KPageUp and KPageDown translations do not take effect unless the
List
child widget is posted.
- <Btn1Down>:
- CBArmAndDropDownList()
- <Btn1Up>:
- CBDisarm()
The following lists the List translations in the drop-down list. When ComboBox
XmNcomboBoxType is
XmDROP_DOWN_LIST,
<osfActivate>,
<osfCancel>, and
Return are overridden by ComboBox
actions.
- :c <Key><osfDown>:
- CBDropDownList()
- :c <Key><osfUp>:
- CBDropDownList()
- :<Key><osfCancel>:
- CBCancel()
- :<Key><osfActivate>:
- CBActivate()
- ∼s ∼m ∼a<Key>Return:
- CBActivate()
Accelerators¶
The following accelerators are added to ComboBox and its children. The
accelerators may not directly correspond to a translation table. If the
translation is not listed below, it may depend on the context of the event.
- :c <Key><osfUp>:
- CBDropDownList()
- :<Key><osfUp>:
- CBListAction(Up)
- :c <Key><osfDown>:
- CBDropDownList()
- :<Key><osfDown>:
- CBListAction(Down)
- :c <Key><osfBeginLine>:
- CBListAction(ListBeginData)
- :c <Key><osfEndLine>:
- CBListAction(ListEndData)
- :<Key><osfPageUp>:
- CBListAction(ListPrevPage)
- :<Key><osfPageDown>:
- CBListAction(ListNextPage)
A drop-down ComboBox also adds accelerators to its List child. Aside from the
accelerators that are already listed in this section, those accelerators are
the default TextField key translations.
Action Routines¶
The
XmComboBox action routines are as follows:
- CBActivate():
- Calls the XmNselectionCallback callbacks. If the
XmNcomboBoxType is XmDROP_DOWN_COMBO_BOX or
XmDROP_DOWN_LIST, it unposts the list. If the parent is a manager,
passes the event to the parent.
- CBArmAndDropDownList():
- If the pointer is within the down arrow, draws the shadow of the arrow in
the selected state, and then posts the list.
- CBCancel():
- If the XmNcomboBoxType is XmDROP_DOWN_COMBO_BOX or
XmDROP_DOWN_LIST, pops down the list. If the parent is a manager,
passes the event to the parent.
- CBDisarm():
- Redraws the arrow in an unselected state.
- CBDropDownList():
- If XmNcomboBoxType is XmDROP_DOWN or
XmDROP_DOWN_LIST, and list is not displayed, posts the list. If
list is displayed, it unposts the list.
- CBListAction(ListBeginData):
- Moves the location cursor to the first item in the list. In Normal Mode,
this also deselects any current selection, selects the first item in the
list, and calls the XmNbrowseSelectionCallback selection
callback.
- CBListAction(ListEndData):
- Moves the location cursor to the last item in the list. In Normal Mode,
this also deselects any current selection, selects the last item in the
list, and calls the XmNbrowseSelectionCallback selection
callback.
- CBListAction(ListPrevPage):
- Scrolls the list to the previous page, moving the location cursor to a new
item. This action also selects the new item, deselects any current
selection, and calls the XmNbrowseSelectionCallback callbacks. If
the ComboBox is not a drop-down type, then this action does nothing.
- CBListAction(ListNextPage):
- Scrolls the list to the next page, moving the location cursor to a new
item. This action also selects the new item, deselects any current
selection, and calls the XmNbrowseSelectionCallback callbacks. If
the ComboBox is not a drop-down type, then this action does nothing.
- CBListAction(Up):
- Moves the location cursor to the previous item in the list. This action
also selects the previous item, deselects any current selection, and calls
the XmNbrowseSelectionCallback callbacks. Note that, unlike the
List ListPrevItem action, this action wraps around.
- CBListAction(Down):
- Moves the location cursor to the next item in the list. This action also
selects the next item, deselects any current selection, and calls the
XmNbrowseSelectionCallback callbacks. Note that, unlike the List
ListNextItem action, this action wraps around.
Virtual Bindings¶
The bindings for virtual keys are vendor specific. For information about
bindings for virtual buttons and keys, see
VirtualBindings(3).
