Question

When working with NativeWindow‘s in AIR, can you get an event everytime the window is minimized / unminimized? I tried hooking up with DisplayStateChanged but its not firing when the window is minimized. Do you know how to get such an event?

I’m on Windows 7, 32-bit, and I’m running AIR 3.5.

This is the init code:

        var init:NativeWindowInitOptions = new NativeWindowInitOptions();
        init.maximizable = true;
        init.resizable = true;
        init.type = NativeWindowType.NORMAL;
        init.minimizable = true;
        window = new NativeWindow(init);
        window.alwaysInFront = true;
        window.addEventListener(NativeWindowDisplayStateEvent.DISPLAY_STATE_CHANGE, dispChange, false, 0, true);

And this is the handler:

    private function dispChange(e:NativeWindowDisplayStateEvent):void {


        // if minimized / un-minimized
        if (e.beforeDisplayState == NativeWindowDisplayState.NORMAL && e.afterDisplayState == NativeWindowDisplayState.MINIMIZED) {
            trace("MINIMIZED!");

        }else if (e.beforeDisplayState == NativeWindowDisplayState.MINIMIZED && e.afterDisplayState == NativeWindowDisplayState.NORMAL) {
            trace("Un-MINIMIZED!");

        }
    }

The closest thing I could get to a minimized event was the activate events. Whenever the user clicks outside the app, that window gets deactivated. You can then minimize the window automatically using minimize(). But the deactivated event is also called when the user minimizes the window / switches to another. And when the user switches back you get a call to activate.

window.addEventListener(Event.ACTIVATE, dispActive, false, 0, true);
window.addEventListener(Event.DEACTIVATE, dispDective, false, 0, true);

private function dispActive(e:Event):void {
    // un-minimized
}
private function dispDective(e:Event):void {
    // deactivated .. minimize again to be sure
    window.minimize();
}
