Hi,

I have a Problem with the display update System of our beloved prefuse

The main discussion should stay in
https://sourceforge.net/forum/forum.php?..._id=343013
but here I have the chance to show a screesshot.

In short: I have an Overview Window for my GraphDisplay (MainWindow). I try to show the area that is visible in the MainWindow as an Rectagle in the Overview Windows (via an PaintListener).

All works more or less, but the Overview Window does not update in areas where there are no Nodes. So the "Border" gets cut or not shown.

See attachments

Try adding a custom repaint listener to the main display (and pass your overview Display into it) which runs overviewdisplay.repaint() on postPaint(Display,Graphics2D)... Works fine

ex:

public class UnderviewPaintListener implements PaintListener
{
private Display overDisplay;
public UnderviewPaintListener(Display o)
{
overDisplay=o;
}
public void postPaint(Display d, Graphics2D g)
{
int xscale = (int) d.getDisplayX();
int yscale = (int) d.getDisplayY();
int wscale = (int) d.getWidth();
int hscale = (int) d.getHeight();
overDisplay.damageReport();
overDisplay.repaint(xscale,yscale,wscale,hscale);
}
public void prePaint(Display d, Graphics2D g)
{
}
}
