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