32 | /* | |
33 | wxDynamicSashWindow works by internally storing a tree of Implementation | |
34 | objects (wxDynamicSsahWindowImpl) and Leaf objects | |
35 | (wxDynamicSashWindowLeaf). The wxDynamicSashWindow has a pointer to one | |
36 | implementation, and each implementation either has a pointer to a one | |
37 | leaf (m_leaf) or a pointer to two children implementation objects | |
38 | (m_child). The leaves each are responsible for drawing the frame and | |
39 | decorations around one user-provided views and for responding to mouse | |
40 | and scrollbar events. | |
41 | ||
42 | A resulting tree might look something like this: | |
43 | ||
44 | wxDynamicSashWindow | |
45 | | | |
46 | +- wxDynamicSashWindowImpl | |
47 | | | |
48 | +- wxDynamicSashWindowLeaf | |
49 | | | | |
50 | | +- user view window | |
51 | | | |
52 | +- wxDynamicSashWindowImpl | |
53 | | | |
54 | +- wxDynamicSashWindowLeaf | |
55 | | | | |
56 | | +- user view window | |
57 | | | |
58 | +- wxDynamicSashWindowLeaf | |
59 | | | |
60 | +- user view window | |
61 | ||
62 | Each time a split occurs, one of the implementation objects removes its | |
63 | leaf, generates two new implementation object children, each with a new | |
64 | leaf, and reparents the user view which was connected to its old leaf | |
65 | to be one of the new leaf's user view, and sends a Split event to the | |
66 | user view in the hopes that it will generate a new user view for the | |
67 | other new leaf. | |
68 | ||
69 | When a unification ocurrs, an implementation object is replaced by one | |
70 | of its children, and the tree of its other child is pruned. | |
71 | ||
72 | One quirk is that the top-level implementation object (m_top) always | |
73 | keeps a pointer to the implementation object where a new child is needed. | |
74 | (m_add_child_target). This is so that when a new uesr view is added | |
75 | to the hierarchy, AddChild() is able to reparent the new user view to | |
76 | the correct implementation object's leaf. | |
