Description

• Windows are represented as the leaves of a binary tree.

• To each leaf corresponds exactly one window.

• The only nodes which can be focused are the leaves.

• The leaves are called window nodes.

• The other nodes are called container nodes.

• Each container node is a split rectangle.

• Only two methods of node insertion will be provided: replace and pair.

    Example: insertion of a new node (number 4) into the given tree with the
    *replace* method:
  
                 b                                   c
                / \                                 / \
               3   a              -->              4   b
               ^  / \                              ^  / \
                 2   1                               3   a
                                                        / \
                                                       2   1
    +-------------------------+         +-------------------------+
    |            |            |         |            |            |
    |            |     2      |         |            |     3      |
    |            |            |         |            |            |
    |     3      |------------|   -->   |     4      |------------|
    |     ^      |            |         |     ^      |     |      |
    |            |     1      |         |            |  2  |  1   |
    |            |            |         |            |     |      |
    +-------------------------+         +-------------------------+
  
    And with the *pair* method:
  
                 b                                   b
                / \                                 / \
               3   a              -->              c   a
               ^  / \                             / \ / \
                 2   1                           4  3 2  1
                                                 ^
    +-------------------------+         +-------------------------+
    |            |            |         |            |            |
    |            |     2      |         |     4      |     2      |
    |            |            |         |     ^      |            |
    |     3      |------------|   -->   |------------|------------|
    |     ^      |            |         |            |            |
    |            |     1      |         |     3      |     1      |
    |            |            |         |            |            |

Features

• Triple window borders. Rationale: with single borders, it might happen that the color of the window border is too close to the color of its inner or outer environment to be visible.
• Directional pair splitting preselection (the feedback will be drawn in the window border pixman).
• Set or get settings and call methods at runtime.
• Configuration file in Lua.

Planned Features

• Don't automatically give the focus to toolbar windows.
• When a fullscreen window looses the focus, its fullscreen state will be set to false if the window to be focused is in the same desktop.
• Close every window except the focused one.
• Tree transformations: directional leaf swap, node pulling, rotation...
• Rounded corners ? (cairo).
