the Title states my problem almost completely.
I have some combo box classes which derive from JComboBox, additionally we use the PlasticUI from JGoodies. My Problem is that when I navigate through the available items in the drop down popup those items are automatically being selected. This only happens when I use the navigation keys, hovering with the mouse over the objects is fine. In my case this is pretty bad because it somehow provokes the lazy-loaded data in the object to be loaded and slow the combo box down immensely.
How can I turn this behavior off?
I tried debugging, but I cannot find a place to set a breakpoint properly, too much magic happening in the background :/
Plzz help :)
You can use the function ActionEvent.getModifiers() to check if the ItemChangeEvent got fired with the keyboard or the mouse.
JCheckBox box = new JCheckBox();
box.addActionListener(new ActionListener() {
@Override
public void actionPerformed(final ActionEvent e) {
if (e.getModifiers() == 0) {
System.out.println("keyboard");
} else {
System.out.println("mouse");
}
}
});
