Window size & position

Free

Allows you to move and resize the window freely, with commands from inside the application (through system calls) or from external user commands (such as grabbing the window border to stretch or move the window).

Floating

Move and resize operations are allowed only from user commands, but internal operations are intercepted and neutralized.

Locked size

It is only possible to move the window from user external commands, and the window can't be stretched or altered from internal operations.

Anchored

The window will remain fixed in its original position.
