Hi,

I am the author of the Byecycle plugin for eclipse.
http://byecycle.sourceforge.net/

I am having trouble getting scrollbars to work correctly. They just sit
there grayed-out and do nothing:

FigureCanvas canvas = new FigureCanvas(shell);
canvas.setScrollBarVisibility(FigureCanvas.ALWAYS);

IFigure figure = new Figure();
XYLayout layout = new XYLayout();
figure.setLayoutManager(layout);

Label label = new Label("Banana");
figure.add(label);
label.setSize(label.getPreferredSize());
label.setLocation(new Point(30, 30));

canvas.setContents(figure);


You can run the example below to see what I mean. I am using
org.eclipse.draw2d_3.2.1.v20060921.jar but I get the same problem on
draw2d jars since 2005.

Could somebody please help me?

Thanks, Klaus.

canvas.setContents(figure);


shell.open();
shell.layout();

try {
Thread.sleep(1000);
} catch (InterruptedException e) {}

while (!shell.isDisposed()) {
while (!_display.readAndDispatch()) {
}
}
}
