How can I check whether Exposé is being activated or not?
- by yangumi
Hi,
I'm creating an application that emulates MacBook's multi-touch Trackpad. As you may know, on MacBook's trackpad
if you swipe 4 fingers up, it triggers the Show Desktop.
if you swipe 4 fingers down, it shows the Exposé.
However, if the Show Desktop is being activated and you swipe 4 fingers down, it will come back to the normal mode. The same goes with the Exposé: if the Exposé is being activated and you swipe 4 fingers up, it will also come back to the normal mode.
Here is the problem: I use the keyboard shortcut F3 to show the Exposé and F11 to show the Show Desktop. The problem is, when the Show Desktop is being activated, if I press F3, it will go straight to the Exposé. And when the Exposé is being activated, if I press F11 it will go straight to the Show Desktop. But I want it to behave like Trackpad, which I guess its code may look like this
- FourFingersDidSwipeUp {
if (isExposeBeingActivated() || isShowDesktopBeingActivated()) {
pressKey("Esc");
} else {
pressKey("F11");
}
}
But I don't know how to implement the "isExposeBeingActivated()" and "isShowDesktopBeingActivated()" methods. I've tried creating a window and check whether its size has changed (on assumption that if the Expose is being activated, its size should be smaller), but the system always returns the same size. I tried monitoring the background processes during the Expose, but nothing happened. Does anyknow have any suggestions on this?
(I'm sorry if my English sounds weird.)
