HUD contents not displayed on OS X

[GoogleCodeExporter]

The following code will only display a HUD without contents on OS X. In 
Windows, it works as 
intended.

HudWindow hud = new HudWindow("HUD");
hud.getJDialog().setSize(200, 200);
hud.getJDialog().setVisible(true);
hud.setContentPane(new JButton("foo"));

Using 0.9.5 of Macwidgets with Java 1.6 on Mac OS X 10.5.7.

Hmm... why would you want to set the content pane to a button?

Adding a button is just the easiest way to show what happens. If I add a panel 
with other components on it, the 
same thing happens, ie. nothing is displayed.

Maybe this is not a bug after all, but a human error. If I am not supposed to 
add for example a panel as a content 
pane, what is supposed to go there?

You should be adding to the content pane, not replacing it:

hudWindow.getContentPane().add(new JButton("Hello World");

I tried that method as well, but the results are the same. I still don't have 
any components visible on my HUD 
windows.

I've now tried the following code using both Windows Vista and Mac OS X. I've 
also 
tried both Java 1.5 and 1.6 on OS X with the same results.

HudWindow hud = new HudWindow("foo");
hud.getJDialog().setSize(200,200);
hud.getJDialog().setVisible(true);
hud.getContentPane().add(HudWidgetFactory.createHudButton("bar"));

In OS X, an empty HUD window is displayed. In Vista, the button is added as it 
should.

What happens if you use Java 1.5? I don't have access to 10.5.7 yet, so I won't 
be able to look into this until it's 
released in September.

No improvements when using Java 1.5.

It seems as though the order in which the HudWindow is initialised is 
important. If I for example do like this, 
it works also in OS X:

HudWindow hud = new HudWindow("foo");
hud.getContentPane().add(new JButton("bar"));
hud.getJDialog().setSize(200,200);
hud.getJDialog().setVisible(true);

Thus, if the JButton is added to the content pane before the HudWindow is set 
visible, it works just fine. If 
howerver the line hud.getContentPane().add(new JButton("bar")); is moved to the 
bottom, no button is 
displayed.

This is a workaround that I personally can live with for now.

Do you observe the same behavior with a regular JDialog? If so, I'll close this 
issue. Also, make sure your creating 
your UI on the EDT.

No, with a regular JDialog, contents can be added after the initialization.

Are you sure you ran this against JDK 1.5? I just ran into a bug at work 
involving this same issue when running 
against JDK 6.

[GoogleCodeExporter]

Yes, positive. I tried it with both JDK 1.5 and 1.6 just to be sure, and the 
same thing happened.

I've experienced the same issues when developing with the HUD window.

I'm talking about 1.6 not 1.5.

The order is important, there is a hack around it to change the contents whilst 
the
HUD is showing so long as you don't want to change the size of the HUD (if you 
do
then you get the flicker bug on Mac). At work at the minute, can post code when 
I get
back home.

This is not a Mac Widgets for Java issue, but a standard Swing issue. You have 
two options: 

1) Add your components to your window before you display them
2) Add you components to your window after you display them and then call:

        window.validate();
        window.repaint();
