Hi Jules,

&nbsp;

Is there a way to get the visible portion of a component in a viewport in the child component wirthout

asking for the viewport ?

The widget doesn't know it is a viewport

&nbsp;

Right now I'm using the&nbsp;getClipBounds of the Graphics but it could be smaller in case of a partial redraw.

&nbsp;

Thanks,

You could convert the bounds of the child component into the parent's coord space, and then clip it to the parent's bounds? Doing that operation recursively would be a more general way of getting the visible area.
