XmSelectionBox(3X)
XmSelectionBox --The SelectionBox widget class
As shipped in IRIX 6.5.19. Unchanged since IRIX 6.5.
NAME XmSelectionBox --The SelectionBox widget class SYNOPSIS #include <Xm/SelectioB.h> VERSION This page documents version 1.2 of the Motif library. 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. Ad- ditional 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 cate- gories 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 ar- eas. * 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, Con- straint, 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 program- mer 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 re- maining letters (in either lowercase or uppercase, but include any under- scores 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).

The callback reason is XmCR_APPLY. XmNapplyLabelString 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". XmNcancelCallback Specifies the list of callbacks called when the user activates the Cancel button. The callback reason is XmCR_CANCEL. XmNcancelLabelString Specifies the string label for the Cancel button. The default for this resource depends on the locale. In the C locale the de- fault is "Cancel". XmNchildPlacement 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 XmNdialogType Determines the set of SelectionBox children widgets that are cre- ated 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 XmDIA- LOG_WORK_AREA. XmCreatePromptDialog and XmCreateSelectionDia- log set and append this resource to the creation arglist sup- plied by the application. This resource cannot be modified af- ter creation. XmNhelpLabelString 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". XmNlistItems 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. XmNlistItemCount Specifies the number of items in the SelectionBox list. The value must not be negative. XmNlistLabelString 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. XmNlistVisibleItemCount Specifies the number of items displayed in the SelectionBox list. The value must be greater than 0 unless XmNdialogType is XmDIA- LOG_PROMPT; in that case the value is always 0. The default is dynamic based on the height of the list. XmNminimizeButtons 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. XmNmustMatch Specifies whether the selection widget should check if the user's selection in the text edit field has an exact match in the Selec- tionBox list when the OK button is activated. If the selection does not have an exact match, and XmNmustMatch is True, the XmN- noMatchCallback callbacks are called. If the selection does have an exact match or if XmNmustMatch is False, XmNokCallback call- backs are called. XmNnoMatchCallback Specifies the list of callbacks called when the user makes a se- lection 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 XmN- mustMatch is true. XmNokCallback 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. XmNokLabelString 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". XmNselectionLabelString 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". XmNtextAccelerators Specifies translations added to the Text widget child of the Se- lectionBox. 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. XmNtextColumns Specifies the number of columns in the Text widget. The value must be greater than 0. XmNtextString Specifies the text in the text edit selection field. Inherited Resources SelectionBox inherits behavior and resources from the following super- classes.

Accelerators The XmNtextAccelerators are added to the Text descendant of XmSelectionBox. The default accelerators are listed below. These accelerators may not di- rectly 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: SelectionBoxUpOrDown(0|1|2|3): 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 re- places the text with that item. When called with a 2 argument, selects the first item in the list and re- places the text with that item. When called with a 3 argument, selects the last item in the list and re- places the text with that item. SelectionBoxRestore(): 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: MAny KCancel: Calls the activate callbacks for the cancel button if it is sen- sitive. If no cancel button exists and the parent of the Selec- tionBox is a manager, passes the event to the parent. KActivate:Calls the activate callbacks for the button with the keyboard fo- cus. 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 asso- ciated with KActivate is called before the SelectionBox actions associated with KActivate. In a multi-line Text widget, any KAc- tivate event except KEnter calls the Text action associated with KActivate, then the SelectionBox actions associated with KActi- vate. 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. <OK Button Activated>: 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. <Apply Button Activated>: Calls the XmNapplyCallback callbacks with reason XmCR_APPLY. <Cancel Button Activated>: Calls the XmNcancelCallback callbacks with reason XmCR_CANCEL. <Help Button Activated>: Calls the XmNhelpCallback callbacks with reason XmCR_HELP. <MapWindow>: Calls the callbacks for XmNmapCallback if the SelectionBox is a child of a Dialog shell. <UnmapWindow>: Calls the callbacks for XmNunmapCallback if the SelectionBox is the child of a DialogShell.
