NAME

XmSelectionBox - The SelectionBox widget class  

SYNOPSIS

#include <Xm/SelectioB.h>


 

DESCRIPTION

SelectionBox is a general dialog widget that allows the user to select one item from a list. By default a SelectionBox includes the following: A scrolling list of alternatives An editable text field for the selected alternative Labels for the list and text field Three or four buttons

The default button labels are OK, Cancel, and Help. By default an Apply button is also created; if the parent of the SelectionBox is a DialogShell it is managed, and otherwise it is unmanaged. Additional children may be added to the SelectionBox after creation. The first child is used as a work area. The value of XmNchildPlacement determines if the work area is placed above or below the Text area, or above or below the List area. Additional children are laid out in the following manner: Menubar--The first menu bar child is placed at the top of the window. Buttons--All XmPushButton widgets or gadgets, and their subclasses are placed after the OK button in the order of their creation. The layout of additional children which are not in the above categories is undefined.

The user can select an item in two ways: by scrolling through the list and selecting the desired item or by entering the item name directly into the text edit area. Selecting an item from the list causes that item name to appear in the selection text edit area.

The user may select a new item as many times as desired. The item is not actually selected until the user presses the OK PushButton.

The default value for the XmBulletinBoard resource XmNcancelButton is the Cancel button unless XmNdialogType is XmDIALOG_COMMAND, when the default is NULL. The default value for the XmBulletinBoard resource XmNdefaultButton is the OK button unless XmNdialogType is XmDIALOG_COMMAND, when the default is NULL.

For SelectionBox and its subclasses, the default value for XmNinitialFocus is the text edit area.

The user can specify resources in a resource file for the automatically created widgets and gadgets of SelectionBox. The following list identifies the names of these widgets (or gadgets) and the associated SelectionBox areas. List Items Label--``Items'' List Items--``ItemsList'' Selection Label--``Selection'' Selection Text--``Text'' Selection Separator--``Separator''
 

Classes

SelectionBox inherits behavior and resources from Core, Composite, Constraint, XmManager, and XmBulletinBoard Classes.

The class pointer is xmSelectionBoxWidgetClass.

The class name is XmSelectionBox.
 

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).

Specifies the list of callbacks called when the user activates the Apply button. The callback reason is XmCR_APPLY. Specifies the string label for the Apply button. The default for this resource depends on the locale. In the C locale the default is ``Apply''. Specifies the list of callbacks called when the user activates the Cancel button. The callback reason is XmCR_CANCEL. Specifies the string label for the Cancel button. The default for this resource depends on the locale. In the C locale the default is ``Cancel''. Specifies the placement of the work area child. The possible values are: XmPLACE_ABOVE_SELECTION--places the work area child above the Text area XmPLACE_BELOW_SELECTION--places the work area child below the Text area XmPLACE_TOP--places the work area child above the List area, and below a menubar, if one is present Determines the set of SelectionBox children widgets that are created and managed at initialization. The following are possible values: XmDIALOG_PROMPT--all standard children except the list and list label are created, and all except the Apply button are managed XmDIALOG_COMMAND--only the list, the selection label, and the text field are created and managed XmDIALOG_SELECTION--all standard children are created and managed XmDIALOG_FILE_SELECTION--all standard children are created and managed XmDIALOG_WORK_AREA--all standard children are created, and all except the Apply button are managed
If the parent of the SelectionBox is a DialogShell, the default is XmDIALOG_SELECTION; otherwise, the default is XmDIALOG_WORK_AREA. XmCreatePromptDialog and XmCreateSelectionDialog set and append this resource to the creation arglist supplied by the application. This resource cannot be modified after creation. Specifies the string label for the Help button. The default for this resource depends on the locale. In the C locale the default is ``Help''. Specifies the items in the SelectionBox list. XtGetValues for this resource returns the list items themselves, not a copy of the list items. The application must not free the returned items. Specifies the number of items in the SelectionBox list. The value must not be negative. Specifies the string label to appear above the SelectionBox list containing the selection items. The default for this resource depends on the locale. In the C locale the default is ``Items'' unless XmNdialogType is XmDIALOG_PROMPT; in that case the default is NULL. Specifies the number of items displayed in the SelectionBox list. The value must be greater than 0 unless XmNdialogType is XmDIALOG_PROMPT; in that case the value is always 0. The default is dynamic based on the height of the list. Sets the buttons to the width of the widest button and height of the tallest button if False. If True, button width and height are not modified. Specifies whether the selection widget should check if the user's selection in the text edit field has an exact match in the SelectionBox list when the OK button is activated. If the selection does not have an exact match, and XmNmustMatch is True, the XmNnoMatchCallback callbacks are called. If the selection does have an exact match or if XmNmustMatch is False, XmNokCallback callbacks are called. Specifies the list of callbacks called when the user makes a selection from the text edit field that does not have an exact match with any of the items in the list box. The callback reason is XmCR_NO_MATCH. Callbacks in this list are called only if XmNmustMatch is true. Specifies the list of callbacks called when the user activates the OK button. The callback reason is XmCR_OK. If the selection text does not match a list item, and XmNmustMatch is True, the XmNnoMatchCallback callbacks are called instead. Specifies the string label for the OK button. The default for this resource depends on the locale. In the C locale the default is ``OK''. Specifies the string label for the selection text edit field. The default for this resource depends on the locale. In the C locale the default is ``Selection''. Specifies translations added to the Text widget child of the SelectionBox. The default includes bindings for the up and down keys for auto selection of list items. This resource is ignored if XmNaccelerators is initialized to a nondefault value. Specifies the number of columns in the Text widget. The value must be greater than 0. Specifies the text in the text edit selection field.

Callback Information

A pointer to the following structure is passed to each callback: typedef struct {
  int      reason;
  XEvent   * event;
  XmString value;
  int      length; } XmSelectionBoxCallbackStruct;

Indicates why the callback was invoked Points to the XEvent that triggered the callback Indicates the XmString value selected by the user from the SelectionBox list or entered into the SelectionBox text field Indicates the size in bytes of the XmString value
 

Translations

XmSelectionBox inherits translations from XmBulletinBoard.
 

Accelerators

The XmNtextAccelerators are added to the Text descendant of XmSelectionBox. The default accelerators are listed below. These accelerators may not directly correspond to a translation table. KUp: SelectionBoxUpOrDown(0) KDown: SelectionBoxUpOrDown(1) KBeginData: SelectionBoxUpOrDown(2) KEndData: SelectionBoxUpOrDown(3) KRestore: SelectionBoxRestore()


 

Action Routines

The XmSelectionBox action routines are described below: When called with a 0 argument, selects the previous item in the list and replaces the text with that item.

When called with a 1 argument, selects the next item in the list and replaces the text with that item.
When called with a 2 argument, selects the first item in the list and replaces the text with that item.
When called with a 3 argument, selects the last item in the list and replaces the text with that item. Replaces the text value with the list selection. If no item in the list is selected, clears the text.
 

Additional Behavior

The SelectionBox widget has the additional behavior described below: Calls the activate callbacks for the cancel button if it is sensitive. If no cancel button exists and the parent of the SelectionBox is a manager, passes the event to the parent. Calls the activate callbacks for the button with the keyboard focus. If no button has the keyboard focus, calls the activate callbacks for the default button if it is sensitive. In a List widget or single-line Text widget, the List or Text action associated with KActivate is called before the SelectionBox actions associated with KActivate. In a multi-line Text widget, any KActivate event except KEnter calls the Text action associated with KActivate, then the SelectionBox actions associated with KActivate. If no button has the focus, no default button exists, and the parent of the SelectionBox is a manager, passes the event to the parent. If XmNmustMatch is True and the text does not match an item in the file list, calls the XmNnoMatchCallback callbacks with reason XmCR_NO_MATCH. Otherwise, calls the XmNokCallback callbacks with reason XmCR_OK. Calls the XmNapplyCallback callbacks with reason XmCR_APPLY. Calls the XmNcancelCallback callbacks with reason XmCR_CANCEL. Calls the XmNhelpCallback callbacks with reason XmCR_HELP. Calls the callbacks for XmNmapCallback if the SelectionBox is a child of a Dialog shell. Calls the callbacks for XmNunmapCallback if the SelectionBox is the child of a DialogShell.
 

Virtual Bindings

The bindings for virtual keys are vendor specific. For information about bindings for virtual buttons and keys, see VirtualBindings(3X).
