Generate event on key release

[max]

I would like to create an event to trigger an action when I press a key on the keyboard, and an other event to trigger another action, when I release the key. First part is straightforward, but the release part seems more tricky, since only keypress events show up in the log window. Does anybody know how to do this in eventghost?

Since the KB Plugin doesn't generate KeyPressed KeyReleased Events, you will have to use a small trick.

The KB plugin generates enduring Events, which allow you to repeat the assigned macro as long as the key is down (using autorepeat action).
So what you need to do is generate an event when the macro ends its repeat.
You will want to use a timer for that.

Each time the macro runs, it will reset the timer.
As long as the macro runs before the timer ends, the timer won't generate any event.
When the repeat stops, the timer will expire and generate its event.

Of course, you will get the event some time after the key is actually released.
This delay depends on how you set up the autorepeat action and the timer.

I have attached a sample Tree. The assigned Key is LShift.

I realize that my demo tree will only fire Timer.keyUp events. This is not really usefull if you want to do this for several keys.

So if you want to get events that looks like :
Timer.LShift_up (and have LShift automatically replaced by the name of the key that is down)

In the demo tree of my previous post, replace the timer action by this one :

Code: Select all

<?xml version="1.0" encoding="UTF-8" ?>
<EventGhost Version="1610">
    <Action>
        EventGhost.PythonCommand(u'eg.plugins.Timer.TimerAction(u\'KeyUp\', 0, 1, 0.15, eg.event.suffix+"_up", False, True, 1, u\'00:00:00\')')
    </Action>
</EventGhost>

That seems to work really well. That was exactly what I was looking for. In fact I only need for one button at the moment, but it obviously becomes a lot more useful with the suffix after. Thank you very much.
