Member Function Documentation

void LayeredCanvas::clear (    )  [inline]

Clear the canvas, i.e. remove all objects from the canvas and draw the background color on the entire canvas. Reimplemented in ScribbleCanvas.

int LayeredCanvas::getNrOfLayers (    )  [inline]

void LayeredCanvas::enableLayer (  int    layer )  [inline]

void LayeredCanvas::disableLayer (  int    layer )  [inline]

boolean LayeredCanvas::isEnabled (  int    layer )  [inline]

int LayeredCanvas::addObject (  CanvasObject    obj )  [inline]

int LayeredCanvas::addObject (  CanvasObject    obj, int    index, int    objID )  [inline]

This is the only function that really adds objects. If index or objID are -1 a suited value will be determined. NOTE TO PROGRAMMERS: take care that supplying an object ID can cause multiple objects to have the same identifier! In normal situations the repository should supply the ID.

CanvasObject LayeredCanvas::getObject (  int    objID )  [inline]

CanvasObject LayeredCanvas::getObject (  int    layer, int    index )  [inline]

CanvasObject LayeredCanvas::getObjectCopy (  int    objID, boolean    ics )  [inline]

CanvasObject LayeredCanvas::getObjectCopy (  int    layer, int    index, boolean    ics )  [inline]

void LayeredCanvas::removeObject (  int    objID )  [inline]

void LayeredCanvas::removeObject (  int    layer, int    index )  [inline]

void LayeredCanvas::removeAllObjects (    )  [inline]

int LayeredCanvas::getObjectID (  CanvasObject    obj )  [inline]

String [] LayeredCanvas::whichClassesAt (  int    layer )  [inline]

boolean LayeredCanvas::declareClassAt (  String    className, int    layer )  [inline, protected]

int LayeredCanvas::findLayer (  CanvasObject    obj )  [inline, protected]
