Adobe AIR Keyboard Hook

Question

I\'m trying to add a feature to my AIR app that can listen for (configurable) global keyboard events even when the app is minimized. Ex: CTRL-ALT-SHIFT-F12 to grab a screens

Answer 1

I don't think that Adobe Air programs can process keypress events unless the application is in focus.

Even this question regarding a Global handler for keypresses states that the application must be in focus.

Answer 2

Try hooking onto the stage's KeyboardEvent:

stage.addEventListener(KeyboardEvent.KEY_DOWN,KeyHandler);  

function KeyHandler(e:KeyboardEvent){
    trace ("Key Code: " + e.keyCode);  
    trace ("Control? " + e.ctrlKey);  
    trace ("Shift? " + e.shiftKey);  
    trace ("Alt? " + e.altKey);  
}

One method I use is to monitor the clipboard in the AIR app, that only allows you to react based on copied data, but it's at least sort of a way to listen for input when the app does not have focus.

Answer 4

With NativeProcess, you could write an external app pretty easily to listen for global keyboard events and send them back to your AIR app. I might be going down this path now...

I'm testing my Air application in Flash CS5 and I need to disable keyboard shortcuts so I can test my own shortcuts. I can get ctrl-F to work, but ctrl-C will not.

I notice that my keyboard shortcuts WILL work if it's a standard AS3 file that I'm testing.
