Thanks for your quick reply, Etienne. I understand that the getPreferredSize
would fail, but I was hoping that there would be good solutions to these
very common problems - I really, really don't like the idea of creating
extensions to solve these types of things. Perhaps I can try using
ULCFillers, but it just feels that there should be a more elegant way of
emulating simple Swing stuff like this.

Hi Stuart
At the time you set the max size, the preferred size is not known (you
are on the server-side and no Swing component has been created yet).
combo.setMaximumSize(combo.getPreferredSize());
If I were you, I'd write a combo box extension that returns the
preferred size when asked for the max size or maybe play around with
adding a trailing ULCFiller and see if this helps you achieve the
toolbar layout that you want.

Subject: [ULC-developer] ULCComboBox getPreferredSize/setMaximumSize
Converting a program from Swing to ULC, I notice a change of behavior,
which
I hope you can give me some advise on.
I have included below a class that demonstrates the problem, followed by
a
Swing class that is working as expected. Basically, the combobox in the
toolbar is being extended to the end. This happens by default in Swing,
but
there a simple setMaximumSize of the preferred size sets the width to a
reasonable size. In ULC, this isn't working as it does in Swing. Can you
look at this, please, and offer any suggestions on how I might rework
this
to get it working like Swing?
Thanks!

public class BugsFrameApp extends AbstractApplication {
public void start() {
new BugsFrame().setVisible(true);
}
public static void main(String[] args) {
DevelopmentRunner.setApplicationClass(BugsFrameApp.class);
DevelopmentRunner.run();
}
class BugsFrame extends ULCFrame {
public BugsFrame() {
super("Bugs");
setDefaultCloseOperation(ULCFrame.TERMINATE_ON_CLOSE);
setSize(800, 900);
addComponents();
}
private void addComponents() {
ULCToolBar toolbar = new ULCToolBar();
toolbar.add(new ULCButton("A"));
toolbar.add(new ULCButton("B"));
toolbar.addSeparator();
ULCComboBox combo = new ULCComboBox(new String[]{"Red",
"Green",
"Blue"});
toolbar.add(combo);
combo.setMaximumSize(combo.getPreferredSize());
add(toolbar, ULCBorderLayoutPane.NORTH);
}
}
}
This is the Swing class that works perfectly:
public class BugsFrameApp extends JFrame {
public static void main(String[] args) {
new BugsFrameApp().setVisible(true);
}
public BugsFrameApp() {
super("Bugs");
setDefaultCloseOperation(ULCFrame.TERMINATE_ON_CLOSE);
setSize(800, 900);
addComponents();
}
private void addComponents() {
JToolBar toolbar = new JToolBar();
toolbar.add(new JButton("A"));
toolbar.add(new JButton("B"));
toolbar.addSeparator();
JComboBox combo = new JComboBox(new String[]{"Red", "Green",
"Blue"});
toolbar.add(combo);
combo.setMaximumSize(combo.getPreferredSize());
add(toolbar, BorderLayout.NORTH);
}
}
