handling TAB in JTable celleditor

[Manuel Moons]

Hello,

Does anyone know how I can stop a tablecelleditor from losing focus when the tab key is pressed? I have an editor which contains 2 combo boxes. I want to switch between those 2 combos when pressing tab. At the moment the focus of the editor is lost. How can I fix this?

By default JTable has an action bound to the tab key. I don't know if this will work, but you can try removing that binding:

InputMap ima = yourTable.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
ima.put(KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0), "do-nothing");

Here the string "do-nothing" can be anything so long as it doesn't match anything in the action map. (So "selectNextColumnCell" would be a poor choice.)

Hey thanks,

I actually already came up with that solution myself. It worked. I attached a custom action to my cellEditor component and by doing that I made sure that it (the key) will not be forwarded to the table. So for other editors it will still work and I can handle my own TAB key.
