Fast page scrolling in charmap misses refreshes #165

Closed robmcmullen closed 4 years ago

robmcmullen commented 7 years ago

Holding down PageUp/Down so it get into autorepeat somehow misses some refreshes and the cursor index gets ahead of the view in the window. The grid controls are always ok, but the bitmaps get behind.

I think the multiple on_char events that show up are the problem; the scroll position gets out of sync so what it thinks is the first row isn't updated.

On windows this shows up virtually all the time, but provides a clue. Every other window other than the one with the focus is updated correctly.

Not using wx grid control any more!
