Hi,

I have a JPanel using the gridlayout layout manager which diplays rows of information. In another JPanel I have a button which causes the information displayed to increase by one (the remaining empty rows are filled with empty JPanels).
The problem is that, after clicking the add button, the Panel clears and shows nothing until I either resize the window or just click the frame. Doing either of these seem to force a panel refresh?

In the redraw code I do the following:

CODE


addARowOfInfo(JPanel panel)
{
   panel.removeAll();
   panel.repaint();
   drawAllRows();
}

Works perfectly, thanks!

I do have to re-add the layout manager though which I guess is removed by panel.removeAll()?

Yeah, I think that removeAll would remove everything including the layout manager, but I don't really know. Glad to know it worked anyway icon_up.gif
