Hi all,
I would like to be able to use the mouse pointer outside my SimpleGame, and gaing focus when I am hovering the SimpleGame window. I do not want to use Swing to do that.
Any clue?
Thanx!

hmm, detecting the cursor moving out of your window is easy, then call MouseInput.get().setCursorVisible( true ).
the problem is to detect when it's moving back into the window. As you don't know if it's occluded and/or the position of the lwjgl window…
…does somebody know methods to detect that? maybe lwjgl methods we could wrap?
Hi,
i'm not sure if this is what you want.
I use something like the following:

} catch (LWJGLException e) {

}
So i can have a custom mouse cursor but the mouse is not grabbed.
Note that the cursor image have to be RGBA.
Hope it helps.

I think LWJGL has a webstart that does this.

Exactly where i get it from. ^^
