How do I prevent JDialog from showing in gnome-panel(Linux)?

问题 I have a class: public class ANote extends JDialog{...} In GNOME(Linux) it shows an entry in the gnome-panel. I want it to show nothing (under Windows the instances of JDialog show nothing in the Windows taskbar), because there may be present several instances of the class simultaneously, and this overcrowds the gnome-panel.

How do I get the monitor of an active window in GNOME?

由 跟風遠走 提交于 2019-12-11 17:10:57
问题 I am very new to GNOME extension development, and I am having a hard time working with it, due to a profound lack of documentation (or maybe my Internet is clandestinely censored) of the API.

Now, what I would like to do, is find out
