让JButton手动保持沮丧

Question

我想让JButton保持按下状态，并且在某些事件发生之前无法再次按下是否有一种简单的方法可以做到这一点？

Answer 1

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.

Answer 2

Perhaps you just want to disable the button? Try setEnabled(false) in your callback for the button.

Answer 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.
