I would like to make a JButton stay pressed down and not be able to be pressed again until some event occurs is there an easy way to do this?
回答1:
Perhaps you just want to disable the button? Try setEnabled(false) in your callback for the button.
回答2:
You should probably look at the JToggleButton class. Associate it with an Action which calls setEnabled(false) to disable interaction.
Once your event happens you call setEnabled(true) and setSelected(false) to restore the original state of the button.
回答3:
I think you should have a look at the JButton Swing class Here. It allows you to have a 2 state button, and so for what you need, you may just need to attach your button to some boolean, allowing it to be selected or not.
