XmCommand(Xm)


XmCommand -- the Command widget class

Syntax

#include <Xm/Command.h>

Description

Command is a special-purpose composite widget for command entry that provides a built-in command-history mechanism. Command includes a command-line text-input field, a command-line prompt, and a command-history list region.

One additional WorkArea child may be added to the Command after creation.

Whenever a command is entered, it is automatically added to the end of the command-history list and made visible. This does not change the selected item in the list, if there is one.

Many of the new resources specified for Command are actually SelectionBox resources that have been renamed for clarity and ease of use.

Classes

Command inherits behavior and resources from Core, Composite, Constraint, XmManager, XmBulletinBoard, and XmSelectionBox classes.

The class pointer is xmCommandWidgetClass.

The class name is XmCommand.

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).

XmNcommand
Contains the current command-line text. This is the XmNtextString resource in SelectionBox, renamed for Command. This resource can also be modified via XmCommandSetValue and XmCommandAppendValue functions. The command area is a Text widget.

XmNcommandChangedCallback
Specifies the list of callbacks that is called when the value of the command changes. The callback reason is XmCR_COMMAND_CHANGED. This is equivalent to the XmNvalueChangedCallback of the Text widget, except that a pointer to an XmCommandCallbackStructure is passed, and the structure's value member contains the XmString.

XmNcommandEnteredCallback
Specifies the list of callbacks that is called when a command is entered in the Command. The callback reason is XmCR_COMMAND_ENTERED. A pointer to an XmCommandCallback structure is passed.

XmNhistoryItems
Lists XmString items that make up the contents of the history list. This is the XmNlistItems resource in SelectionBox, renamed for Command. XtGetValues for this resource returns the list items themselves, not a copy of the list items. The application must not free the returned items.

XmNhistoryItemCount
Specifies the number of XmStrings in XmNhistoryItems. This is the XmNlistItemCount resource in SelectionBox, renamed for Command. The value must not be negative.

XmNhistoryMaxItems
Specifies the maximum number of items allowed in the history list. Once this number is reached, an existing list item must be removed before a new item can be added to the list. For each command entered, the first list item is removed from the list, so the new command can be added to the list. The value must be greater than 0.

XmNhistoryVisibleItemCount
Specifies the number of items in the history list that should be visible at one time. In effect, it sets the height (in lines) of the history list window. This is the XmNlistVisibleItemCount resource in SelectionBox, renamed for Command. The value must be greater than 0. The default is dynamic based on the height of the list.

XmNpromptString
Specifies a prompt for the command line. This is the XmNselectionLabelString resource in SelectionBox, renamed for Command. The default may vary depending on the value of the XmNstringDirection resource and the locale. In the C locale the default is ``>''.

Inherited resources

Command inherits behavior and resources from the following superclasses. For a complete description of each resource, 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;
   	XmString	value;
   	int		length;
   } XmCommandCallbackStruct;

reason
Indicates why the callback was invoked.

event
Points to the XEvent that triggered the callback.

value
Specifies the XmString in the CommandArea.

length
Specifies the size of the command in value.

Translations

XmCommand inherits translations from XmSelectionBox.

Accelerators

The XmNtextAccelerators from XmSelectionBox are added to the Text descendant of XmCommand.

Action routines

The XmCommand action routines are described below:

SelectionBoxUpOrDown(0|1|2|3):
When called with a 0 argument, selects the previous item in the history list and replaces the text with that item.

When called with a 1 argument, selects the next item in the history list and replaces the text with that item.

When called with a 2 argument, selects the first item in the history list and replaces the text with that item.

When called with a 3 argument, selects the last item in the history list and replaces the text with that item.

Calls the callbacks for XmNcommandChangedCallback.

Additional behavior

The Command widget has the additional behavior described below:

MAny KCancel:
If the parent of the Command is a manager, the event is passed to the parent.

KActivate in Text:
Calls the Text widget's XmNactivateCallback callbacks. If the text is empty, this action then returns. Otherwise, if the history list has XmNhistoryMaxItems items, it removes the first item in the list. It adds the text to the history list as the last item, clears the text, and calls the XmNcommandEnteredCallback callbacks.

<Key> in Text:
When any change is made to the text edit widget, this action calls the callbacks for XmNcommandChangedCallback.

<DoubleClick> or <KActivate> in List:
Calls the List widget's XmNdefaultActionCallback callbacks. If the history list has XmNhistoryMaxItems items, this action removes the first item in the list. It adds the selected List item to the history list as the last item, clears the text, and calls the XmNcommandEnteredCallback callbacks.

<FocusIn>:
Calls the callbacks for XmNfocusCallback.

<MapWindow>:
When a Command that is the child of a DialogShell is mapped, this action calls the callbacks for XmNmapCallback.

<UnmapWindow>:
When a Command that is the child of a DialogShell is unmapped, this action calls the callbacks for XmNunmapCallback.

Virtual bindings

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