XmToggleButton — The ToggleButton widget class

Synopsis

#include <Xm/ToggleB.h>

Description

ToggleButton sets nontransitory state data within an application. Usually this widget consists of an indicator (square, diamond, or round) with either text or a pixmap on one side of it. However, it can also consist of just text or a pixmap without the indicator.

The toggle graphics display a 1-of-many, N-of-many, or 1-of-many-round selection state. When a toggle indicator is displayed, a square indicator shows an N-of-many selection state, a diamond-shaped indicator shows a 1-of-many selection state, and a circle-shaped indicator shows a 1-of-many-round selection state.

ToggleButton implies a set or unset state. In the case of a label and an indicator, an empty indicator (square, diamond, or round) indicates that ToggleButton is unset, and a filled indicator shows that it is set. The indicator may be filled with a check mark, a cross, or the select color. In the case of a pixmap toggle, different pixmaps are used to display the set/unset states. ToggleButton can also indicate an indeterminate state. In the case of a label and an indicator, an indeterminate state is indicated by a stippled flat box. In the case of a pixmap toggle, a different pixmap is used to display the indeterminate state.

The default behavior associated with a ToggleButton in a menu depends on the type of menu system in which it resides. By default, <Btn1> controls the behavior of the ToggleButton. In addition, <Btn3> controls the behavior of the ToggleButton if it resides in a PopupMenu system. The actual mouse button used is determined by its RowColumn parent.

Label’s resource XmNmarginLeft may be increased to accommodate the toggle indicator when it is created.

ToggleButton uses the XmQTmenuSystem and XmQTspecifyRenderTable traits.

Classes

ToggleButton inherits behavior, resources, and traits from Core, XmPrimitive, and XmLabel.

The class pointer is xmToggleButtonWidgetClass.

The class name is XmToggleButton.

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).

XmNarmCallback

Specifies the list of callbacks called when the ToggleButton is armed. To arm this widget, press the active mouse button while the pointer is inside the ToggleButton. For this callback, the reason is XmCR_ARM.

XmNdetailShadowThickness

Specifies the thickness of the indicator shadow. The default thickness is 2 pixels.

XmNdisarmCallback

Specifies the list of callbacks called when ToggleButton is disarmed. To disarm this widget, press and release the active mouse button while the pointer is inside the ToggleButton. This widget is also disarmed when the user moves out of the widget and releases the mouse button when the pointer is outside the widget. For this callback, the reason is XmCR_DISARM.

XmNfillOnSelect

Fills the indicator with the color specified in XmNselectColor and switches the top and bottom shadow colors when set to True. If unset, fills the indicator with the unselect color. If indeterminate, fills the indicator with half select color and half unselect color. Otherwise, it switches only the top and bottom shadow colors. The default is True only if a box type of indicator (such as a check box) is specified, or if the XmNindicatorType is a 1-of type and a toggle indicator is drawn.

If XmNfillOnSelect is True, XmNset is XmSET, and XmNindicatorOn is XmINDICATOR_NONE the ToggleButton’s background is set to XmNselectColor. For the other XmNindicatorOn values, only the indicator is filled with XmNselectColor.

XmNindeterminateInsensitivePixmap

Specifies the pixmap to be displayed as the button face when the Label XmNlableType resource is XmPIXMAP or XmPIXMAP_AND_STRING, the ToggleButton XmNset resource is XmINDETERMINATE, and the Core XmNsensitive resource is False.

XmNindeterminatePixmap

XmNindicatorOn

Specifies that if a toggle indicator is to be drawn, it will be drawn to one side of the toggle text or pixmap, depending on the XmNlayoutDirection resource of the widget. The default value is XmINDICATOR_FILL. Toggles accept the following values:

XmINDICATOR_NONE: No space is allocated for the indicator, and it is not displayed. Any shadows around the entire widget are switched when the toggle is selected or unselected.
XmINDICATOR_BOX: The toggle indicator is in the shape of a shadowed box.
XmINDICATOR_FILL: If the value of the XmDisplay XmNenableToggleVisual resource is True , the visuals are those of XmINDICATOR_CHECK_BOX ; if False , the indicator visuals are those of XmINDICATOR_BOX.
XmINDICATOR_CHECK: The toggle indicator is in the shape of a checkmark in the foreground color.
XmINDICATOR_CHECK_BOX: The toggle indicator is in the shape of a checkmark enclosed in a box. This is the default if the XmDisplay XmNenableToggleVisual resource is set.
XmINDICATOR_CROSS_BOX: The toggle indicator is in the shape of a cross enclosed in a box.
XmINDICATOR_CROSS: The toggle indicator is in the shape of a cross.

All ToggleButton checks and crosses should be drawn in the foreground color.

If this resource is not XmINDICATOR_NONE, it will control the appearance of the toggle visual. If XmNset is XmINDETERMINATE and XmNindicatorOn is not XmINDICATOR_NONE, this resource shows a stippled flat box. If XmNset is XmINDETERMINATE, XmNindicatorOn is XmINDICATOR_NONE, and XmNtoggleMode is XmTOGGLE_INDETERMINATE, the label and the ToggleButton are stippled with a combination of the XmNselectColor and the XmNunselectColor color, and the border is flat.

XmNindicatorSize

Sets the size of the indicator. If no value is specified, the size of the indicator is based on the size of the label string or pixmap. If the label string or pixmap changes, the size of the indicator is recomputed based on the size of the label string or pixmap. Once a value has been specified for XmNindicatorSize, the indicator has that size, regardless of the size of the label string or pixmap, until a new value is specified. The size of indicators inside menus may differ from those outside of menus. Note that a change in this resource may also cause a change in the values of the inherited resources XmNmarginTop, XmNmarginBottom, and XmNmarginLeft.

XmNindicatorType

Specifies if the indicator is a 1-of or N-of indicator. For the 1-of indicator, the value can be XmONE_OF_MANY, XmONE_OF_MANY_ROUND, or XmONE_OF_MANY_DIAMOND. For the N-of indicator, the value is XmN_OF_MANY. This value specifies only the visuals and does not enforce the behavior. When the ToggleButton is in a radio box, the default is XmONE_OF_MANY; otherwise, the default is XmN_OF_MANY. Legal values are:

XmONE_OF_MANY: When the Display XmNenableToggleVisual resource is set, indicators are drawn with the same appearance as XmONE_OF_MANY_ROUND; otherwise, they appear the same as XmONE_OF_MANY_DIAMOND.
XmN_OF_MANY: The indicators are drawn as specified by the XmNindicatorOn resource.
XmONE_OF_MANY_ROUND: A shadowed circle.
XmONE_OF_MANY_DIAMOND: A shadowed diamond.

XmNselectColor

Allows the application to specify what color fills the center of the square, diamond-shaped, or round indicator when it is set. If this color is the same as either the top or the bottom shadow color of the indicator, a one-pixel-wide margin is left between the shadows and the fill; otherwise, it is filled completely. The results of this resource depend on the value of the Display resource XmNenableToggleColor. A value of True causes the fill color to use the XmHIGHLIGHT_COLOR color by default. A value of False causes the fill color to use the background color. This resource’s 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. To set the background of the button to XmNselectColor when XmNindicatorOn is XmINDICATOR_NONE, the value of XmNfillOnSelect must be explicitly set to True.

This resource is also used as the background color when all of the following conditions are met: the button is armed in a menu, the XmNenableEtchedInMenu resource is True, the XmNindicatorOn resource is False, and the XmNfillOnSelect resource is True.

This resource can take the following values:

XmDEFAULT_SELECT_COLOR: Is the same as the current dynamic default, which is a color between the background and the bottom shadow color.
XmREVERSED_GROUND_COLORS: Forces the select color to the foreground color and causes the default color of any text rendered over the select color to be in the background color.
XmHIGHLIGHT_COLOR: Forces the fill color to use the highlight color.

XmNselectInsensitivePixmap

Specifies a pixmap used as the button face when the ToggleButton is selected, the button is insensitive, and the Label resource XmNlabelType is set to XmPIXMAP or XmPIXMAP_AND_STRING. If the ToggleButton is unselected and the button is insensitive, the pixmap in XmNlabelInsensitivePixmap is used as the button face. If no value is specified for XmNlabelInsensitivePixmap, that resource is set to the value specified for XmNselectInsensitivePixmap.

XmNselectPixmap

Specifies the pixmap to be used as the button face when XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING, and the ToggleButton is selected. When the ToggleButton is unselected, the pixmap specified in the Label’s XmNlabelPixmap is used. If no value is specified for XmNlabelPixmap, that resource is set to the value specified for XmNselectPixmap.

XmNset

Represents the state of the ToggleButton. A value of XmUNSET indicates that the ToggleButton is not set. A value of XmSET indicates that the ToggleButton is set. A value of XmINDETERMINATE indicates that the ToggleButton is in an indeterminate state (neither set nor unset). The ToggleButton states cycle through in the order of XmSET, XmINDETERMINATE (if XmNtoggleMode is set to XmTOGGLE_INDETERMINATE), and XmUNSET, and then back around to XmSET. If XmNtoggleMode is set to XmTOGGLE_BOOLEAN, then the ToggleButton states cycle through in the order of XmSET, then XmUNSET, and then back around to XmSET. Setting this resource sets the state of the ToggleButton.

XmNspacing

Specifies the amount of spacing between the toggle indicator and the toggle label (text or pixmap).

XmNtoggleMode

Specifies the mode of the ToggleButton as either XmTOGGLE_BOOLEAN or XmTOGGLE_INDETERMINATE. The XmTOGGLE_INDETERMINATE value allows the XmNset resource to be able to accept the values XmINDETERMINATE, XmSET, and XmUNSET. The XmNtoggleMode resource is forced to XmTOGGLE_BOOLEAN if the toggle is in an XmRowColumn widget whose radio behavior is XmONE_OF_MANY. In XmTOGGLE_BOOLEAN mode, the XmNset resource can only accept XmSET and XmUNSET.

XmNunselectColor

Allows the application to specify what color fills the center of the square, diamond-shaped, or round indicator when it is not set. If this color is the same as either the top or the bottom shadow color of the indicator, a one-pixel-wide margin is left between the shadows and the fill; otherwise, it is filled completely. This resource’s default for a color display is XmNbackground. For a monochrome display, the default is set to the background color. To set the background of the button to XmNunselectColor when XmNindicatorOn is XmINDICATOR_NONE, the value of XmNfillOnSelect must be explicitly set to True. This resource acts like the XmNselectColor resource, but for the case when XmNset is XmUNSET.

XmNvalueChangedCallback

Specifies the list of callbacks called when the ToggleButton value is changed. To change the value, press and release the active mouse button while the pointer is inside the ToggleButton. This action also causes this widget to be disarmed. For this callback, the reason is XmCR_VALUE_CHANGED.

XmNvisibleWhenOff

Indicates that the toggle indicator is visible in the unselected state when the Boolean value is True. When the ToggleButton is in a menu, the default value is False. When the ToggleButton is in a RadioBox, the default value is True.

Callback Information

A pointer to the following structure is passed to each callback:

typedef struct
{
 int reason;
 XEvent * event;
 int set;
} XmToggleButtonCallbackStruct;

reason: Indicates why the callback was invoked
event: Points to the XEvent that triggered the callback
set: Reflects the ToggleButton’s state, either XmSET (selected), XmUNSET (unselected), or XmINDETERMINATE (neither). Note that the reported state is the state that the ToggleButton is in after the event has been processed. For example, suppose that a user clicks on a ToggleButton to change it from the unselected state to the selected state. In this case, ToggleButton changes the value of set from XmUNSET to XmSET prior to calling the callback.

Translations

XmToggleButton includes translations from Primitive. Additional XmToggleButton translations for buttons not in a menu system are described in the following list.

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

The following key names are listed in the X standard key event translation table syntax. This format is the one used by Motif to specify the widget actions corresponding to a given key. A brief overview of the format is provided under VirtualBindings(3). For a complete description of the format, please refer to the X Toolkit Instrinsics Documentation.

c<Btn1Down>:: ButtonTakeFocus()
≈c<Btn1Down>:: Arm()
≈c<Btn1Up>:: Select() Disarm()

Action Routines

The XmToggleButton action routines are

Arm():: If the button was previously unset, this action does the following: if XmNindicatorOn is True, it draws the indicator shadow so that the indicator looks pressed; if XmNfillOnSelect is True, it fills the indicator with the color specified by XmNselectColor. If XmNindicatorOn is False, it draws the button shadow so that the button looks pressed. If XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING, the XmNselectPixmap is used as the button face. This action calls the XmNarmCallback callbacks.; If the button was previously set, this action does the following: if both XmNindicatorOn and XmNvisibleWhenOff are True, it draws the indicator shadow so that the indicator looks raised; if XmNfillOnSelect is True, it fills the indicator with the background color. If XmNindicatorOn is False, it draws the button shadow so that the button looks raised. If XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING, the XmNlabelPixmap is used as the button face. This action calls the XmNarmCallback callbacks.
ArmAndActivate():: If the ToggleButton was previously set, unsets it; if the ToggleButton was previously unset, sets it.; In a menu, this action unposts all menus in the menu hierarchy. Unless the button is already armed, it calls the XmNarmCallback callbacks. This action calls the XmNvalueChangedCallback and XmNdisarmCallback callbacks.; Outside a menu, if the button was previously unset, this action does the following: if XmNindicatorOn is True, it draws the indicator shadow so that the indicator looks pressed; if XmNfillOnSelect is True, it fills the indicator with the color specified by XmNselectColor. If XmNindicatorOn is False, it draws the button shadow so that the button looks pressed. If XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING, the XmNselectPixmap is used as the button face. This action calls the XmNarmCallback, XmNvalueChangedCallback, and XmNdisarmCallback callbacks.; Outside a menu, if the button was previously set, this action does the following: if both XmNindicatorOn and XmNvisibleWhenOff are True, it draws the indicator shadow so that the indicator looks raised; if XmNfillOnSelect is True, it fills the indicator with the background color. If XmNindicatorOn is False, it draws the button shadow so that the button looks raised. If XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING, the XmNlabelPixmap is used as the button face. This action calls the XmNarmCallback, XmNvalueChangedCallback, and XmNdisarmCallback callbacks.
BtnDown():: This action unposts any menus posted by the ToggleButton’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. If the ToggleButton was previously set, unsets it; if the ToggleButton was previously unset, sets it. It calls the XmNvalueChangedCallback callbacks and then the XmNdisarmCallback callbacks.
ButtonTakeFocus():: Causes the ToggleButton to take keyboard focus when Ctrl<Btn1Down> is pressed, without activating the widget.
Disarm():: Calls the callbacks for XmNdisarmCallback.
Help():: In a Pulldown or Popup MenuPane, unposts all menus in the menu hierarchy and 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 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.
ProcessDrag():: Drags the contents of a ToggleButton label, identified when BTransfer is pressed. This action sets the XmNconvertProc of the DragContext to a function that calls the XmNconvertCallback procedures, possibly multiple times, for the _MOTIF_DROP selection. This action is undefined for ToggleButtons used in a menu system.
Select():: If the pointer is within the button, takes the following actions: If the button was previously unset, sets it; if the button was previously set, unsets it. This action calls the XmNvalueChangedCallback callbacks.

Additional Behavior

This widget has the following additional behavior:

<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 ToggleButton is not in a menu and the cursor leaves and then reenters the ToggleButton’s window while the button is pressed, this action restores the button’s armed appearance.
<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 ToggleButton is not in a menu and the cursor leaves the ToggleButton’s window while the button is pressed, this action restores the button’s unarmed appearance.
