XmTabStack - Man Page

TabStack inherits behavior and resources form Core, Composite, Constraint, XmManager and XmBulletinBoard Classes.

The class pointer is xmTabStackWidgetClass.

The class name is XmTabStack.

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 or 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).

XmNfontList

Specifies the XmFontList to use when drawing the label strings for the tabs.

XmNhighlightThickness

Specifies the thickness of the rectangle drawn around the label string and label pixmap of the tab with keyboard traversal.

XmNstackedEffect

Specifies if the visuals should depict a stack of folders, True, or if the XmTabStack should use all available space for its children, False.

XmNtabAutoSelect

Specifies if a tab is automatically selected when it receives keyboard traversal.

XmNtabCornerPercent

Specifies the percent of the font height that should be used for the corner visual.

XmNtabLabelSpacing

Specifies the amount of space to leave between a text label and a pixmap in the tab area.

XmNtabMarginHeight

Specifies the vertical border that is placed around the label area of a tab.

XmNtabMarginWidth

Specifies the horizontal border that is placed around the label area of a tab.

XmNtabMode

Specifies the mode in which the XmTabStack distributes the tabs. Valid values for this resource include:

XmTABS_BASIC

Distributes the tabs in either a vertical or horizontal row and clips the tabs if there is not enough room to display all the tabs.

XmTABS_STACKED

Distributes the tabs in either a vertical or horizontal row. If there is not enough room to display all the tabs additional rows are added. When a tab is selected, its row is moved next to the children in the stack.

XmTABS_STACKED_STATIC

Distributes the tabs in either a vertical or horizontal row. If there is not enough room to display all the tabs additional rows are added. The positions of rows are not changed when tabs are selected.

XmNtabOffset

Specifies the amount of indentation used to stagger the tab rows when displaying tabs in either the XmTABS_STACKED or XmTABS_STACKED_STATIC mode.

XmNtabOrientation

Specifies the orientation of the tab, and the rotation factor of the tab label. Valid values for this resource include:

XmTAB_ORIENTATION_DYNAMIC

Specifies that the orientation of the tabs should be calculated dynamically based on the XmNtabSide resource.

XmTABS_LEFT_TO_RIGHT

Specifies that the text appears at the default rotation.

XmTABS_RIGHT_TO_LEFT

Specifies that the text appears upside down.

XmTABS_TOP_TO_BOTTOM

Specifies that the text should be rotated to the vertical position with the first character drawn at the lowest y position and the bottom of the text faces the lowest x position.

XmTABS_BOTTOM_TO_TOP

Specifies that the text should be rotated to the vertical, position with the first character drawn at the highest y position and the bottom of the text faces the highest x position.

XmNtabSelectColor

Specifies the color of the selected tab.

XmNtabSelectedCallback

Specifies the list of callbacks to call when a child becomes the selected tab.

XmNtabSelectPixmap

Specifies the pixmap of the selected tab.

XmNtabSide

Specifies the location of the tab with respect to the children of the XmTabStack. Valid values for this resource include:

XmTABS_ON_TOP

Specifies that the tabs should be placed above the children.

XmTABS_ON_BOTTOM

Specifies that the tabs should be placed below the children.

XmTABS_ON_RIGHT

Specifies that the tabs should be placed to the right of the children.

XmTABS_ON_LEFT

Specifies that the tabs should be placed to the left of the children.

XmNtabStyle

Specifies the appearance of the tabs associated with the children of the XmTabStack. Valid values for this resource include:

XmTABS_BEVELED

Draws the corners of the tabs as an angled line.

XmTABS_ROUNDED

Draws the corners of the tabs as a quarter of a circle.

XmTABS_SQUARED

Draws the tabs as rectangles.

XmNuniformTabSize

Determines if all tabs should have a uniform major dimension, where the major dimension is width if the tab orientation is XmTABS_LEFT_TO_RIGHT or XmTABS_RIGHT_TO_LEFT or height if the tab orientation is XmTABS_TOP_TO_BOTTOM or XmTABS_BOTTOM_TO_TOP. When XmNtabMode is either XmTABS_STACKED or XmTABS_STACKED_STATIC, this resource is forced to True.

XmNuseImageCache

Destermines if the Xmmages used for rotating text and pixmaps should be cached. This increases performance but uses up more memory.

XmNfreeTabPixmap

Specifies that the pixmaps assigned to the XmNlabelPixmap resources should be freed when the widget is destroyed.

XmNtabAlignment

Specifies the alignment of the tab label. Valid values for this resource include:

XmALIGNMENT_BEGINNING

Aligns the label to the left side of the available space.

XmALIGNMENT_CENTER

Aligns the label centered in the available space.

XmALIGNMENT_END

Aligns the label to the right side of the available space.

XmNtabBackground

Specifies the background pixel for the tab.

XmNtabBackgroundPixmap

Specifies the background pixmap for the tab.

XmNtabForeground

Specifies the foreground pixel for the tab.

XmNtabLabelPixmap

Specifies the pixmap to display in the tab label.

XmNtabLabelString

Specifies the XmString to display as the textual portion of the tab label. This is copied when set on the widget. The value fetched via XtGetValues should not be freed as it returns a pointer to the widgets value. If you wish to use the value returned from XtGetValues use XmStringCopy the returned value.

XmNtabPixmapPlacement

Specifies the location of the pixmap with respect to the text in the tab label. Valid values for this resource include:

XmPIXMAP_TOP

Specifies that the pixmap should be above the XmString.

XmPIXMAP_BOTTOM

Specifies that the pixmap should be below the XmString.

XmPIXMAP_RIGHT

Specifies that the pixmap should be to the right of the XmString.

XmPIXMAP_LEFT

Specifies that the pixmap should be to the left of the XmString.

XmPIXMAP_ONLY

Specifies that only the pixmap portion of the tab label should be displayed.

XmPIXMAP_NONE

Specifies that only the XmString portion of the tab label should be displayed.

XmNtabStringDirection

Specifies the string direction for the XmString portion of the tab label. Valid values for this resouce include:

XmSTRING_DIRECTION_L_TO_R

Left to right

XmSTRING_DIRECTION_R_TO_L

Right to left

TabStack inherits behavior and resources from the following superclasses. For a complete description of each resource, refer to the man page for that superclass.

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

typedef struct _XmTabStackCallbackStruct {
	int	reason;
	XEvent	*event;
	Widget	selected_child;
} XmTabStackCallbackStruct;

reason

Indicates why the callback was invoked. Valid callbacks reasons include:

XmCR_TAB_SELECTED

Indicates that a child has been made the selected widget.

event

Points to the XEvent that triggered the callback.

selected_child

Contains the widget ID of the selected child.

XmTabStack includes the translations from the XmManager.

The XmTabStack has no additional behavior.

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