StrokeInstall - Enable Strokes in a Widget
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);
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 chil-
dren have been added.
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'.
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 follow-
ing call is made:
XtCallActionProc(W, "PlaySound", NULL, "sound file", 1);
