NAME

       StrokeInstall - Enable Strokes in a Widget

SYNOPSIS

       #include <Stroke.h>

       void StrokeInstall(Widget W);
       void StrokeRemove(Widget W);

       void StrokeSetButton(Widget W, int button);
       int StrokeGetButton(Widget W);

       void StrokeSetDebug(Widget W, Boolean Debug);
       Boolean StrokeGetDebug(Widget W);

       void StrokeSetMapping(Widget W, String Map);
       String StrokeGetMapping(Widget W);

DESCRIPTION

       Enable  Strokes	to  be recognized in the given widget. It first retrieves the resources and installs an Xt event for button press, release
       and, motion on the given widget and all of its children.  Therefore this function should not be called until all of  the  widgets  children
       have been added.

   Resources
       Resources are specified as if they belong to the widget that the strokes are enabled in.

       strokes: stroke action [[,stroke action]...]
	      This provides a mapping of strokes to actions.  By default the action `Stroke-456' is called for stroke `456'.

       strokeSlop: int
	      This  is	used  to  define  a buffer zone between the boxes of the grid.	The amount of slop tolerated is actually the resulting box
	      dimension divided by this slop number. Therefore the larger the slop number the  more  accurate  your  strokes  must  be.   A  value
	      approaching  3 will make it all but impossible to recognize a stroke.  The default value is currently 20.  Run the stroke(1) program
	      with StrokeDebug turned on to show what this means.

       strokeDebug: True | False
	      Turns on `stroke debug mode'.  In this mode the strokes are not erased from the screen when the button is released  and  a  grid	is
	      drawn around the stroke.	Try the stroke(1) program to see what I mean.

       strokeButton: 1 | 2 | 3 | 4 | 5
	      Specifies the button to be used to draw strokes. By default Btn3 is used.

       strokeSound: sound file
	      If  given,  the contents of this resource will be provided as an argument to the `PlaySound' action at the conclusion of the stroke.
	      If the PlaySound action is not defined in your application do not specify this resource.	Specifically the following call is made:

	      XtCallActionProc(W, "PlaySound", NULL, "sound file", 1);

       Boolean XtIsApplicationShell(Widget w);

       Boolean XtIsSessionShell(Widget w);

ARGUMENTS

       w	 Specifies the widget.

       widget_class
		 Specifies the widget class.

       message	 Specifies the message that is to be used.

DESCRIPTION

       The XtClass function returns a pointer to the widget's class structure.

       The XtSuperclass function returns a pointer to the widget's superclass class structure.

       The XtIsSubclass function returns True if the class of the specified widget is equal to or is a subclass of the specified class. The wid-
       get's class can be any number of subclasses down the chain and need not be an immediate subclass of the specified class. Composite widgets
       that need to restrict the class of the items they contain can use XtIsSubclass to find out if a widget belongs to the desired class of
       objects.

       The XtCheckSubclass macro determines if the class of the specified widget is equal to or is a subclass of the specified widget class.  The
       widget can be any number of subclasses down the chain and need not be an immediate subclass of the specified widget class.  If the speci-
       fied widget is not a subclass, XtCheckSubclass constructs an error message from the supplied message, the widget's actual class, and the
       expected class and calls XtErrorMsg.  XtCheckSubclass should be used at the entry point of exported routines to ensure that the client has
       passed in a valid widget class for the exported operation.

       XtCheckSubclass is only executed when the widget has been compiled with the compiler symbol DEBUG defined; otherwise, it is defined as the
       empty string and generates no code.

       To test if a given widget belongs to a subclass of an Intrinsics-defined class, the Intrinsics defines macros or functions equivalent to
       XtIsSubclass for each of the built-in classes. These procedures are XtIsObject, XtIsRectObj, XtIsWidget, XtIsComposite, XtIsConstraint,
       XtIsShell, XtIsOverrideShell, XtIsWMShell, XtIsVendorShell, XtIsTransientShell, XtIsTopLevelShell, XtIsApplicationShell, and XtIsSession-
       Shell.
