I tried to use webbrowser balloon example in my code. Here is the layoutchildren method I override in my balloon window
public override void LayoutChildren(GoObject childchanged)
if (this.Label == null) return; GoControl c = this.Host; if (c == null) return; RectangleF r = this.Label.Bounds; r.Inflate(0, -10); c.Bounds = r;
When I start to drag the balloon window, I see a flashing image of the internal web brower, when release the mouse button, the duplicated image disappears.
What’s the reason that the duplicated image shown while user drags the balloon and How to prevent it?
