XmPushButton(Xm)


XmPushButton -- the PushButton widget class

Syntax

#include <Xm/PushB.h>

Description

PushButton issues commands within an application. It consists of a text label or pixmap surrounded by a border shadow. When a PushButton is selected, the shadow changes to give the appearance that it has been pressed in. When a PushButton is unselected, the shadow changes to give the appearance that it is out.

The default behavior associated with a PushButton in a menu depends on the type of menu system in which it resides. By default, BSelect controls the behavior of the PushButton. In addition, BMenu controls the behavior of the PushButton if it resides in a PopupMenu system. The actual mouse button used is determined by its RowColumn parent.

Thickness for a second shadow, used when the PushButton is the default button, may be specified by using the XmNshowAsDefault resource. If it has a non-zero value, the Label's resources XmNmarginLeft, XmNmarginRight, XmNmarginTop, and XmNmarginBottom may be modified to accommodate the second shadow.

If an initial value is specified for XmNarmPixmap but not for XmNlabelPixmap, the XmNarmPixmap value is used for XmNlabelPixmap.

Classes

PushButton inherits behavior and resources from Core, XmPrimitive, and XmLabel classes.

The class pointer is xmPushButtonWidgetClass.

The class name is XmPushButton.

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).

XmNactivateCallback
Specifies the list of callbacks that is called when PushButton is activated. PushButton is activated when the user presses and releases the active mouse button while the pointer is inside that widget. Activating the PushButton also disarms it. For this callback the reason is XmCR_ACTIVATE.

XmNarmCallback
Specifies the list of callbacks that is called when PushButton is armed. PushButton is armed when the user presses the active mouse button while the pointer is inside that widget. For this callback the reason is XmCR_ARM.

XmNarmColor
Specifies the color with which to fill the armed button. XmNfillOnArm must be set to True for this resource to have an effect. The default for a color display is a color between the background and the bottom shadow color. For a monochrome display, the default is set to the foreground color, and any text in the label appears in the background color when the button is armed.

XmNarmPixmap
Specifies the pixmap to be used as the button face if XmNlabelType is XmPIXMAP and PushButton is armed. This resource is disabled when the PushButton is in a menu.

XmNdefaultButtonShadowThickness
This resource specifies the width of the default button indicator shadow. If this resource is zero, the width of the shadow comes from the value of the XmNshowAsDefault resource. If this resource is greater than zero, the XmNshowAsDefault resource is only used to specify whether this button is the default. The default value is the initial value of XmNshowAsDefault.

XmNdisarmCallback
Specifies the list of callbacks that is called when PushButton is disarmed. PushButton is disarmed when the user presses and releases the active mouse button while the pointer is inside that widget. For this callback, the reason is XmCR_DISARM.

XmNfillOnArm
Forces the PushButton to fill the background of the button with the color specified by XmNarmColor when the button is armed and when this resource is set to True. If False, only the top and bottom shadow colors are switched. When the PushButton is in a menu, this resource is ignored and assumed to be False.

XmNmultiClick
If a button click is followed by another button click within the time span specified by the display's multi-click time, and this resource is set to XmMULTICLICK_DISCARD, do not process the second click. If this resource is set to XmMULTICLICK_KEEP, process the event and increment click_count in the callback structure. When the button is in a menu, the default is XmMULTICLICK_DISCARD; otherwise, for a button not in a menu, XmMULTICLICK_KEEP is the default value.

XmNshowAsDefault
If XmNdefaultButtonShadowThickness is greater than zero, a value greater than zero in this resource specifies to mark this button as the default button. If XmNdefaultButtonShadowThickness is zero, a value greater than zero in this resource specifies to mark this button as the default button with the shadow thickness specified by this resource. The space between the shadow and the default shadow is equal to the sum of both shadows. The default value is zero. When this value is not zero, the Label resources XmNmarginLeft, XmNmarginRight, XmNmarginTop, and XmNmarginBottom may be modified to accommodate the second shadow. This resource is disabled when the PushButton is in a menu.

Callback information

A pointer to the following structure is passed to each callback:
   typedef struct
   {
   	int	reason;
   	XEvent	* event;
   	int	click_count;
   } XmPushButtonCallbackStruct;

reason
Indicates why the callback was invoked.

event
Points to the XEvent that triggered the callback.

click_count
This value is valid only when the reason is XmCR_ACTIVATE. It contains the number of clicks in the last multiclick sequence if the XmNmultiClick resource is set to XmMULTICLICK_KEEP, otherwise it contains 1. The activate callback is invoked for each click if XmNmultiClick is set to XmMULTICLICK_KEEP.

Translations

XmPushButton includes translations from Primitive.

Note that altering translations in #override or #augment mode is undefined.

Additional XmPushButton translations for XmPushButtons not in a menu system are listed below. These translations may not directly correspond to a translation table.

Action routines

The XmPushButton action routines are described below:

Activate():
This action draws the shadow in the unarmed state. If the button is not in a menu and if XmNfillOnArm is set to True, the background color reverts to the unarmed color. If XmNlabelType is XmPIXMAP, the XmNlabelPixmap is used for the button face. If the pointer is still within the button, this action calls the callbacks for XmNactivateCallback.

Arm():
This action arms the PushButton. It draws the shadow in the armed state. If the button is not in a menu and if XmNfillOnArm is set to True, it fills the button with the color specified by XmNarmColor. If XmNlabelType is XmPIXMAP, the XmNarmPixmap is used for the button face. It calls the XmNarmCallback callbacks.

ArmAndActivate():
In a menu, does the following: Unposts all menus in the menu hierarchy. Unless the button is already armed, calls the XmNarmCallback callbacks. Calls the XmNactivateCallback and XmNdisarmCallback callbacks.

Outside a menu, does the following: Draws the shadow in the armed state and, if XmNfillOnArm is set to True, fills the button with the color specified by XmNarmColor. If XmNlabelType is XmPIXMAP, the XmNarmPixmap is used for the button face. Calls the XmNarmCallback callbacks.

Outside a menu, this action also arranges for the following to happen, either immediately or at a later time: The shadow is drawn in the unarmed state and, if XmNfillOnArm is set to True, the background color reverts to the unarmed color. If XmNlabelType is XmPIXMAP, the XmNlabelPixmap is used for the button face. The XmNactivateCallback and XmNdisarmCallback callbacks are called.


BtnDown():
This action unposts any menus posted by the PushButton's parent menu, disables keyboard traversal for the menu, and enables mouse traversal for the menu. It draws the shadow in the armed state and, unless the button is already armed, calls the XmNarmCallback callbacks.

BtnUp():
This action unposts all menus in the menu hierarchy and activates the PushButton. It calls the XmNactivateCallback callbacks and then the XmNdisarmCallback callbacks.

Disarm():
Calls the callbacks for XmNdisarmCallback.

Help():
In a Pulldown or Popup MenuPane, unposts all menus in the menu hierarchy and, when the shell's keyboard focus policy is XmEXPLICT, restores keyboard focus to the widget that had the focus before the menu system was entered. Calls the callbacks for XmNhelpCallback if any exist. If there are no help callbacks for this widget, this action calls the help callbacks for the nearest ancestor that has them.

MenuShellPopdownOne():
In a toplevel Pulldown MenuPane from a MenuBar, unposts the menu, disarms the MenuBar CascadeButton and the MenuBar, and, when the shell's keyboard focus policy is XmEXPLICT, restores keyboard focus to the widget that had the focus before the MenuBar was entered. In other Pulldown MenuPanes, unposts the menu.

In a Popup MenuPane, unposts the menu and restores keyboard focus to the widget from which the menu was posted.


MultiActivate():
If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing.

If XmNmultiClick is XmMULTICLICK_KEEP, this action does the following: Increments click_count in the callback structure. Draws the shadow in the unarmed state. If the button is not in a menu and if XmNfillOnArm is set to True, the background color reverts to the unarmed color. If XmNlabelType is XmPIXMAP, the XmNlabelPixmap is used for the button face. If the pointer is within the PushButton, calls the callbacks for XmNactivateCallback. Calls the callbacks for XmNdisarmCallback.


MultiArm():
If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing.

If XmNmultiClick is XmMULTICLICK_KEEP, this action does the following: Draws the shadow in the armed state. If the button is not in a menu and if XmNfillOnArm is set to True, fills the button with the color specified by XmNarmColor. If XmNlabelType is XmPIXMAP, the XmNarmPixmap is used for the button face. Calls the XmNarmCallback callbacks.


ProcessDrag():
Drags the contents of a PushButton label, identified by pressing BDrag. This action creates a DragContext object whose XmNexportTargets resource is set to COMPOUND_TEXT for a label type of XmSTRING; otherwise, PIXMAP if the label type is XmPIXMAP. This action is undefined for PushButtons used in a menu system.

Additional behavior

This widget has the additional behavior described below:

<EnterWindow>:
In a menu, if keyboard traversal is enabled, this action does nothing. Otherwise, it draws the shadow in the armed state and calls the XmNarmCallback callbacks.

If the PushButton is not in a menu and the cursor leaves and then reenters the PushButton's window while the button is pressed, this action draws the shadow in the armed state. If XmNfillOnArm is set to True, it also fills the button with the color specified by XmNarmColor. If XmNlabelType is XmPIXMAP, the XmNarmPixmap is used for the button face.


<LeaveWindow>:
In a menu, if keyboard traversal is enabled, this action does nothing. Otherwise, it draws the shadow in the unarmed state and calls the XmNdisarmCallback callbacks.

If the PushButton is not in a menu and the cursor leaves the PushButton's window while the button is pressed, this action draws the shadow in the unarmed state. If XmNfillOnArm is set to True, the background color reverts to the unarmed color. If XmNlabelType is XmPIXMAP, the XmNlabelPixmap is used for the button face.
