How do I get the real usable resolution

Question

With

Toolkit.getDefaultToolkit().getScreenSize()

I get the screen size.

But usually this isn't the available size I have for my own program, because on the mac there is a menubar on top and on the bottom an iconbar. Windows also has an iconbar. So how do I get the real available space?

From Java forum:

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
Rectangle bounds = ge.getMaximumWindowBounds();

Now you have the bounds sans platform-dependent desktop decorations. I don't have a Mac around so I only verified that it works on WinXP/JDK6.

Note that if you auto-hide taskbar, the bounds do NOT include taskbar, which is correct.

@Geoffrey This has the side-effect of changing the Look and Feel of the application, correct? Is this necessary? I don't understand what effect it has on the local `GraphicsEnvironment`. – muffin Aug 08 '14 at 19:22
@muffin I think they're just telling you to put the `GraphicsEnvironment` part after look and feel – Nosrep Oct 01 '20 at 13:29

I'm not sure if this will work, but try the GraphicsConfiguration/GraphicsDevice instead. You might not be able to get a bounding box that discount the dock on OS X since the area of the dock is still considered screen space. I can move windows on top of it. I can also move the dock to be on the side and not at the bottom of the screen (same goes for the Windows task bar).

My answer is just one tiny step forward from this. – Geoffrey Zheng Sep 16 '10 at 14:55 — Geoffrey Zheng, Sep 16 '10 at 14:55
