Remove a JFrame from taskbar in Java

问题

I did a quick topic look, but did not find something similar.

My query is: how can I prevent a child window appearing on the Windows taskbar when it is shown?

回答1:

You need to use a JDialog instead of a JFrame

回答2:

JDK 1.7 brings you method setType. Use following method.

JFrame.setType(javax.swing.JFrame.Type.UTILITY)
