Hi,
I would like to know how to get the preferred size of the Figure which
contains other children (and is the contents of the FigureCanvas) before
it's layed out on the screen. Figure.getClientArea(), and getBounds()
return only (64,36) as well as FigureCanvas.computeSize(-1, -1) - (60,32).
The actual shell size is much bigger.
Thank you,
Ihor

public class Test {
public static void main(String[] args) {

Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
shell.setSize(1100, 700);
TestView view = new TestView(shell);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
private static class TestView {
TestView(Composite parent) {
createView(parent);
}
private void createView(Composite parent) {
FigureCanvas fc = new FigureCanvas(parent);
fc.setContents(buildContents());
fc.setLayoutData(new GridData(GridData.FILL_BOTH));
fc.getViewport().setContentsTracksHeight(true);
fc.getViewport().setContentsTracksWidth(true);
}
public Figure buildContents() {
Figure contents = new Panel();
contents.setBackgroundColor(ColorConstants.white);
contents.setLayoutManager(new XYLayout());
contents.setBorder(new LineBorder());
RectangleFigure bar = new RectangleFigure();
Rectangle bounds = new Rectangle(10, 10, 100, 100);
//How can I dynamically fill the whole available canvas area
with this RectangleFigure?
bar.setBounds(bounds);
contents.add(bar, bounds);
System.out.println("contents clientArea: " +
contents.getClientArea());
System.out.println("contents preferredSize: " +
contents.getPreferredSize());
return contents;
}
}
}
Is there a way to find the canvas size before I start putting Figures onto
it?
Thanks Patrik,
Ihor

You're asking what the size of the shell is going to be? Since that
determine the size of everything else. You can invoke layout on the Shell
before you show it.

Change contents' layout to StackLayout (You might not even need the outer
panel; the RectangleFigure can be the contents).
