/*
- FIXME for virtual list controls
+ TODO
- +1. clicking on the item with a mouse is awfully slow, what is going on?
- note that selecting with keyboard seems to be much faster
- => fixed HighlightAll() - iterating over 1000000 items *is* slow
-
- 2. background colour is wrong?
- */
-
-/*
- TODO for better virtual list control support:
-
- 1. less dumb line caching, we should cache at least all those visible
- in the control itself and probably twice as many (we might also need to
- cache the first one always for geometry calculations?)
-
- +2. storing selections: we can't use an array to store the selected indices
- like right now as selecting all in a control with 1000000 items is not
- doable like this - instead, store selections as collection of individual
- items and ranges
-
- => wxSelectionStore
-
- 3. we need to implement searching/sorting somehow
-
- 4. the idea of storing the line index in the line itself is really stupid,
- we shouldn't need it - but for this we have to get rid of all calles to
- wxListLineData::GetFoo() and replace them with something like
- if ( IsVirtual()
- ... we have it ourselves ...
- else
- line->GetFoo();
-
- => done
-
- 5. attributes support: we need OnGetItemAttr() as well!
+ 1. we need to implement searching/sorting for virtual controls somehow
+ ?2. when changing selection the lines are refreshed twice
