Hello Guys !!!

I have an editor which extends a GraphicalEditor .......... and my editor a few connectable figures.

I want to copy and paste a connectable figure on the editor ...... all the copying and pasting stuff works fine for me.

The issue is with the calculation of the paste location (in this case ... the cursor position after copying a connectable figure)

I do something like this ........

public Point getCursorPosition() {
Display display = Display.getDefault();
Point point = getGraphicalViewer().getControl().toControl(display.getCurso rLocation());
return point;
}

This works fine as long as the graphical editor has no scrolling !!!

Once i place the connectabe figures such that the editor has a scroll bar ..... and then do the copy ..... and paste ..... the paste does not happen at the location of my mouse pointer ...... but at positions little off my cursor !!!

Please help me out here .....

Thanx in advance Sad

	public Point getCursorPosition() {
		Display display = Display.getDefault();
		Point point = getGraphicalViewer().getControl().toControl(display.getCursorLocation());
		FigureCanvas figureCanvas = (FigureCanvas)getGraphicalViewer().getControl();
		org.eclipse.draw2d.geometry.Point location = figureCanvas.getViewport().getViewLocation();
		point = new Point(point.x + location.x, point.y + location.y);
		return point;
	}

Regards,
Prasad
