36/*
37 wxDynamicSashWindow works by internally storing a tree of Implementation
38 objects (wxDynamicSsahWindowImpl) and Leaf objects
39 (wxDynamicSashWindowLeaf). The wxDynamicSashWindow has a pointer to one
40 implementation, and each implementation either has a pointer to a one
41 leaf (m_leaf) or a pointer to two children implementation objects
42 (m_child). The leaves each are responsible for drawing the frame and
43 decorations around one user-provided views and for responding to mouse
44 and scrollbar events.
45
46 A resulting tree might look something like this:
47
48 wxDynamicSashWindow
49 |
50 +- wxDynamicSashWindowImpl
51 |
52 +- wxDynamicSashWindowLeaf
53 | |
54 | +- user view window
55 |
56 +- wxDynamicSashWindowImpl
57 |
58 +- wxDynamicSashWindowLeaf
59 | |
60 | +- user view window
61 |
62 +- wxDynamicSashWindowLeaf
63 |
64 +- user view window
65
66 Each time a split occurs, one of the implementation objects removes its
67 leaf, generates two new implementation object children, each with a new
68 leaf, and reparents the user view which was connected to its old leaf
69 to be one of the new leaf's user view, and sends a Split event to the
70 user view in the hopes that it will generate a new user view for the
71 other new leaf.
72
73 When a unification ocurrs, an implementation object is replaced by one
74 of its children, and the tree of its other child is pruned.
75
76 One quirk is that the top-level implementation object (m_top) always
77 keeps a pointer to the implementation object where a new child is needed.
78 (m_add_child_target). This is so that when a new uesr view is added
79 to the hierarchy, AddChild() is able to reparent the new user view to
80 the correct implementation object's leaf.
