How can i implement a 3-state toggle button? I'm using eclipse and windowBuilder and i'm coding a program which has to have 3-state buttons. I used JToggleButtons and their two state for two bu can't implement the third state. What can i do?
P.S. I want three icon state.
Maybe you can look at the code used by com.jidesoft.swing.TristateCheckBox:
See TristateCheckBox.java.
It does inherit from JToggleButton and has three different icon states.
/**
* Maintenance tip - There were some tricks to getting this code
* working:
* <p/>
* 1. You have to overwite addMouseListener() to do nothing
* 2. You have to add a mouse event on mousePressed by calling
* super.addMouseListener()
* 3. You have to replace the UIActionMap for the keyboard event
* "pressed" with your own one.
* 4. You have to remove the UIActionMap for the keyboard event
* "released".
* 5. You have to grab focus when the next state is entered,
* otherwise clicking on the component won't get the focus.
* 6. You have to make a TristateDecorator as a button model that
* wraps the original button model and does state management.
