Types that compute geometries for arbitrary amounts of windows.

The only input such objects get are TilingArea and number of windows. The trait inherits from Debug for purely practical reasons: some types we want to output (WmCommand in particular) rely on derived Debug instances and all types implementing Layout implement Debug anyway.

Required Methods

Compute window geometries.

If a None is returned at a particular position, that window is not to be made visible.

Get the index of the window to the right of the nth window.

Get the index of the window to the left of the nth window.

Get the index of the window to the top of the nth window.

Get the index of the window to the bottom of the nth window.

Decide whether to insert new windows as master.

React to a LayoutMessage, returning true on change.

Provided Methods

React to the first applicable LayoutMessage.

If any reaction is triggered, return true, else false.
