Remove a JFrame from taskbar in Java

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 Wi开发者_如何学运维ndows taskbar when it is shown?

JDK 1.7 brings you method setType. Use following method.

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

You need to use a JDialog instead of a JFrame
