Viewport and get visible rect in child component

[otristan]

Hi Jules,

 

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

 

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

 

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.

Good idea.

Thanks !
