This page is for tracking different parts of the Firefox code that relate to the mouse in different ways.

I suggest looking at widget/src/*/nsWindow.cpp for starters. It seems like the OS-Specific mouse stuff is all done in there.


Here's some code that actually locks the mouse into a rectangle with no width or height in the center of the screen in WIN32.

RECT windowRect;

GetWindowRect(mWnd, &windowRect);

nsIntPoint mousePos; mousePos.x = windowRect.right/2; mousePos.y = windowRect.bottom/2; RECT mouseRect = { mousePos.x, mousePos.y, mousePos.x, mousePos.y }; ClipCursor(&mouseRect); // Forces the mouse to be only within that rectangle on the screen, giving it no width and height means it's locked.
