Capturing key events with Griffon

I'm building a Griffon application, and I want to be able to react to key up events so users can easily navigate forward and back with key presses. Are there any examples around that show us how to listen for key events using Griffon?

Solution

  • Remember that Griffon always gives you choices, in this case you can drop down one level and register KeyEventListeners on the target component. Another option would to be to use the keyStrokeAction node exposed by SwingBuilder, like it's shown by the slideware plugin here https://github.com/griffon/griffon-slideware-plugin/blob/master/griffon-app/views/griffon/plugins/slideware/DeckPlayerView.groovy

    keyStrokeAction(component: deck,
    keyStroke: shortcut('UP'),
    condition: 'in focused window',
    action: lookupAction)
