Hi, thanks for helping! Actually the canvas contains the component's instance and so the component shouldn't need to know anything about the canvas.
I solved the issue with setting explicitWidth and explicitHeight of the component at change. It made the canvas update automatically. Before that I tried with setting .width and .height and it didn't work. Still having the feeling I don't get something right, but I guess another read of the corresponding help files would be enough to make things clearer. Thank you again and thanks to Manish for pointing me in the right direction! --- In [email protected], "Michael Schmalle" <[EMAIL PROTECTED]> wrote: > > Hi, > > Sounds to me from what you have explained, you have not called > setActualSize() on the canvas instance in your custom component;s > updateDisplayList() method. > > Did you ? > > IE > > canvas.setActualSize(canvas.getExplicitOrMeasuredWidth(), > canvas.getExplicitOrMeasuredHeight()) > > Peace, Mike > > On 4/22/07, Manish Jethani <[EMAIL PROTECTED]> wrote: > > > > Is the size of the UIComponent really changing?
