ExmTabButton

The TabButton widget class demonstration widget

Format

#include <Exm/TabB.h>

DESCRIPTION

ExmTabButton is a demonstration widget. OSF provides this widget solely to teach programmers how to write their own Motif widgets. OSF does not support this widget in any way.

The source code for the ExmTabButton widget illustrates how to do the following:

  1. Use the XmQTjoinSide trait

  2. Use several Xme drawing functions

    ExmTabButton is an instantiable widget. ExmTabButton is a subclass of the ExmCommandButton widget, which is itself a subclass of the ExmString widget. Therefore, ExmTabButton inherits all of ExmString's resources for rendering compound strings.

    When a user activates an ExmTabButton widget, the widget calls the callback procedure associated with the XmNactivateCallback resource.

    3. Classes

    ExmTabButton inherits behavior and resources from Core, XmPrimitive, ExmSimple, ExmString, and ExmCommandButton.

    The class pointer is exmTabButtonWidgetClass.

    The class name is ExmTabButton.

    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, ExmN, XmC or ExmC prefix and use the remaining letters. To specify one of the defined values for a resource in a .Xdefaults file, remove the Xm or Exm 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).


    ExmTabButton Resource Set
    Name Class Type Default Access
    ExmNopenSide ExmCOpenSide ExmROpenSide XmLEFT CSG

    ExmNopenSide
    Specifies the side of the child widget that is to be joined to the manager. ExmNopenSide must be one of the following: XmNONE, XmLEFT, XmRIGHT, XmTOP, or XmBOTTOM. For example, if ExmNopenSide is set to XmLEFT, then the left side of the ExmTabButton will be affixed to the right side of the manager widget. XmNONE specifies that the ExmTabButton will not be affixed to its parent. The parent of the ExmTabButton typically overrides the value of the ExmNopenSide resource.

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