Hi Thomas,
Sorry for the mistake i have done in earlier mail thomas. Actually i want
both 'undo/redo' cases.
1. want 'undo/redo' moves of your group with lines?
2. want 'undo/redo' moves of the canvas (whole canvas pan)?
To achieve this, i have added GVTTreeRendererListener for my SVGCanvas. While
doing zoom in,zoom out and moving group elements , it's not executing
RenderingTransform's gvtRenderingCompleted(). Why it's not executing
RenderingCompleted even GVTTreeRendererListener added??
svgCanvas.addGVTTreeRendererListener(new GVTTreeRendererAdapter() {
public void gvtRenderingPrepare(GVTTreeRendererEvent e) {
System.out.println("Renderer Started...");
}
public void gvtRenderingCompleted(GVTTreeRendererEvent e) {
System.out.println("Renderer Completed...");
transformHistory.update(svgCanvas.getRenderingTransform());
previousTransformAction.update();
nextTransformAction.update();
}
});
Thanks,
Selva
