I'm writing a little program with a GUI. It's the first time that im using a JTable and so far everything worked as I wanted it to. But there's one problem I can't seem to solve: Whenever the JTable is focused, no keyboard shortcuts for my menu, i.
The reason is propably that JTable has a very good keyboard support with many built-in functions which is pretty cool and therefore doesn't process the keyboard input.
But I still want to be able to use my own keyboard shortcuts for my menus etc. Mnemonics work fine, but accelerators don't work at all. How can I tell my JTable that it should ignore every keyboard input if the control, alt or a combination of alt, control and shift is pressed?
shortcut « Event « Java Swing Q&A
So far im only able to process my keyboard input if ONLY the control key is pressed by manually shifting the keyboard focus from the table to the menubar and shifting it back onto the table after the control key is released. That doesn't work if im pressing shift before control, though. I also have to use: KeyStroke.
That's the only way that it will work. If I try to add another modifier i. The same goes for shift. It only works if I specifiy shift as the modifier and the KeyEvent. I haven't tried alt yet, but it will propably be the same. It's a start that I got the control key to work, because if the user first presses the control key and THEN all other shortcut key it works without a problem for example control, then shift and 'a' for adding a row to the table.
But if he presses shift first If control is released before the user releases all other keys the InputMap of my menubar [that I configured by using a boolean variable to process the focus back onto the table after control is released if the focus came from the table] will not recognize the input. So the user always has to press control as the first button and release it last. And thats not really good. But thats a lot of work and it would be really annoying to implement all actions and shortcuts twice for the menu AND the table.
I would really appreciate it if anyone of you could help me. I'm stuck with this problem for almost a week now and I really can't find any way to solve it effectivly. Many thanks in advance for your help! John Matthews. If anyone has had any thoughts on this in the last 10 years, I'm facing the same problem. Rob Camick. I believe this basic logic is contained in the processKeyBinding As I understand it the table searches for a binding for the JTable and if one is not found it assumes the KeyStroke should be forward to the editor of the cell.
You can prevent this behaviour by using: table. If it does work then it means you would need to manually start editing on a cell by using F2 or double clicking the cell before you can enter data.
If this doesn't work, then maybe you can provide a custom implementation of processKeyBinding Thanks Rob. I tried the putClientProperty approach, but that doesn't seem to work. But pressing the accelerator keys just changes the selected cell in the table, instead of generating the console output you get if you select the menu items 'manually'.

Usefull when your hotkey listener will directly access or modify some swing components. For simplicity reasons, it is currently impossible to unregister some particular hotkey, but all hotkeys can be reset. On some systems DBus does not allow registering hotkeys for media keys. To fix this, you can use GnomeMediaProvider class. Just create new instance and register media hotkeys with it.
It implements same api as other providers. I would really appreciate it if you could test the library and post some bug reports. I've tested Mac OSX code only in bit virtual machine, and a bit on a real bit machine.
So feedback is greatly appreciated, especially from people who have real Mac with real Apple keyboard, BSD users, people with some advanced keyboards, and just anybody who wants to help.
