Hi, I'm with troubles in this applet, I created a button that when clicked creates another.

But the screen doesn't show the new button unless I resize the screen with the mouse.

here's a code example of what I'm doing:



how can it repaint without resizing?

thanks

When adding or removing components the layout needs to be redone. The easiest way to do that is to call "invalidate()" before "repaint()".
