//! What is the importance of this class?
|
|
//!
|
|
//! Plasma is activating the screen edges for the main panel window
|
|
//! unfortunately this isn't possible for the Latte case.
|
|
//! When a window is hidden at an edge it becomes NOT visible
|
|
//! unfortunately that means that all the animations are
|
|
//! stopped (Qt behaviour) and that creates confusion to the user after the window
|
|
//! reappears because various animations are played (adding-removing tasks/launchers)
|
|
//! that aren't relevant any more.
|
|
//!
|
|
//! In order to workaround the above behaviour Latte is using a
|
|
//! fake window to communicate with KWin and the MAIN Latte::View window
|
|
//! continues to use only mask technique to hide
|
|
