12 FIXME for virtual list controls
13
14 +1. clicking on the item with a mouse is awfully slow, what is going on?
15 note that selecting with keyboard seems to be much faster
16 => fixed HighlightAll() - iterating over 1000000 items *is* slow
17
18 2. background colour is wrong?
19 */
20
21 /*
22 TODO for better virtual list control support:
23
24 1. less dumb line caching, we should cache at least all those visible
25 in the control itself and probably twice as many (we might also need to
26 cache the first one always for geometry calculations?)
27
28 +2. storing selections: we can't use an array to store the selected indices
29 like right now as selecting all in a control with 1000000 items is not
30 doable like this - instead, store selections as collection of individual
31 items and ranges
32
33 => wxSelectionStore
34
35 3. we need to implement searching/sorting somehow
36
37 4. the idea of storing the line index in the line itself is really stupid,
38 we shouldn't need it - but for this we have to get rid of all calles to
39 wxListLineData::GetFoo() and replace them with something like
40 if ( IsVirtual()
41 ... we have it ourselves ...
42 else
43 line->GetFoo();
