Hi,
I'm planning on writing a window manager with the following
characteristics:
- 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*.
- 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 |
| | | | | |
+-------------------------+ +-------------------------+
- Each container node is a split rectangle.
- The splitting method of a container node is either *automatic* or *manual*.
- In the *automatic* splitting mode, the split type is vertical if the width of
the rectangle of the node is greater that its height and horizontal
otherwise.
- Several tree transformations will be provided: directional leaf swap, node
pulling, rotation, contraction, dilatation...
Greetings,
