       DtComboBox — the ComboBox widget class

       #include <Dt/ComboBox.h>


	      This  function has been superseded by the equivalent Motif func‐
	      tion XmComboBox. Please refer to the Motif  Programmer's	Refer‐
	      ence for more information.

       The DtComboBox widget is a combination of a TextField and a List widget
       that provides a list of valid choices for the TextField.	 Selecting  an
       item from this list automatically fills in the TextField with that list

       Widget subclassing is not supported for the DtComboBox widget class.

       The resources for the XmList and XmTextField widgets that  are  created
       by  the	DtComboBox are accessible by using the XtNameToWidget(3) func‐
       tion. The names of these widgets are *List and Text, respectively. (The
       *List  notation is required because the List widget is not an immediate
       descendant of the DtComboBox.  See XtNameToWidget(3).)

       The DtComboBox widget inherits behavior and resources  from  the	 Core,
       Composite and XmManager classes.

       The class pointer is dtComboBoxWidgetClass.

       The class name is DtComboBoxWidget.

   New Resources
       The  following  table  defines  a  set  of widget resources used by the
       application to specify data. The application 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,  the
       application  must  remove  the  DtN or DtC prefix and use the remaining
       letters. To specify one of the defined values for a resource in a .Xde‐
       faults  file,  the  application	must  remove the Dt prefix and use the
       remaining letters (in either lower case or upper	 case,	but  including
       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 applica‐
       ble (N/A).

		 Specifies the number of pixels added between the top and bot‐
		 tom of the text widget and the start of the shadow.

		 Specifies  the	 number	 of pixels added between the right and
		 left sides of the text widget and the start of the shadow.

		 This resource is passed through to  the  XmList  to  set  the
		 XmNselectedItemCount  and XmNselectedItems as the single item
		 in the XmNitems that matches this specified XmString  in  the
		 List. Setting both DtNselectedItem and DtNselectedPosition in
		 the same argument list produces undefined behavior.

		 This resource is passed through to  the  XmList  to  set  the
		 XmNselectedItemCount  and XmNselectedItems as the single item
		 at this specified position in the List. Setting  both	DtNse‐
		 lectedItem  and DtNselectedPosition in the same argument list
		 produces undefined behavior.

		 This callback list is issued when an item  is	selected  from
		 the  DtComboBox  widget's  List. The call_data structure con‐
		 tains a DtComboBoxCallbackStruct with the reason DtCR_SELECT.

		 This resource determines the style of the  DtComboBox.	 There
		 are two choices:

			   Provides an editable text area.

			   Provides a static text area.

   Inherited Resources
       The  DtComboBox widget inherits behavior and resources from the follow‐
       ing named superclasses. For a complete description  of  each  resource,
       see the man page for that superclass.

   Callback Information
       A pointer to the following structure is passed to each DtComboBox call‐

       typedef struct {
	       int	       reason;
	       XEvent	       *event;
	       XmString	       item_or_text;
	       int	       item_position;
       } DtComboBoxCallbackStruct;

       The reason argument indicates why  the  callback	 was  invoked;	it  is
       always DtCR_SELECT.

       The event argument points to the XEvent that triggered the callback, or
       NULL if the callback was not triggered by an XEvent.

       The item_or_text argument is the contents of the	 Text  widget  at  the
       time  the  event	 caused the callback to be invoked.  This data is only
       valid within the scope of the call_data structure, so  the  application
       must copy it when it is used outside of this scope.

       The  item_position argument is the new value of the DtNselectedPosition
       resource in the DtComboBox's List. If this is zero, it means  the  user
       entered a value in the XmTextField widget.

       DtComboBoxAddItem(3),  DtComboBoxDeletePos(3), DtComboBoxSelectItem(3),
       DtComboBoxSetItem(3), DtCreateComboBox(3), Composite(3), Constraint(3),
       Core(3),	 XmList(3), XmManager(3), XmText(3), XmTextField(3), XtGetVal‐
       ues(3), XtSetValues(3).
