android-discuss, How I can make transparent Keyguard

 Hi, I've change the behavior of LockScreen.java to my own but I don't
know how to make transparent or translucent Keyguard. I just wanna see
behind windows(e.g Home app, another users activities etc).
I suppose that I should change something in KeyguardViewManager.java
in show() function but I don't what exactly...
Can anyone help me?

P.S. I have sources for Froyo 2.2.

 Never mind. I found out how to do it.
The first we should change doesForceHide() function in
PhoneWindowManager.java. For Keyguard window this function returns
true.
It cause to forcibly hide everything behind window, in our case it's
Keyguard. Change it to false.

Next we should remove FLAG_SHOW_WALLPAPER in show() in
KeyguardViewManager.java

After this, we'll see transparent keyguard.
