Components don't set explicitWidth and explicitHeight on themselves, they're (optionally) set by the container, and actual sizing is set by the container through setActualSize().
Override measure(), and set measuredWidth and measuredHeight to match your label, and your problems may go away. Also in updateDisplayList you want to set the actual size of the label to the minimu of it's measured size and unscaledWidth x unscaledHeight. -Josh On Wed, Jul 16, 2008 at 2:07 AM, polestar11 <[EMAIL PROTECTED]> wrote: > Hi > > I've been working with custom components & only just noticed a strange > re-drawing issue where I get ghost versions of the children in my > component appearing. > > I've only just noticed this since I set the child's position relative > to unscaledWidth, which changes and so allows me to see N different > older versions of the child.
