This patch fixes the following problem in wxTreeCtrl with multiple selection:

  1. select a few items
  1. delete the.

m_htSelStart  will be point to the latest selected item, but we already have deleted it. So if user press shift + arrow up at this point - we get incorrect selected range.

Thanks for the patch, it seems correct to me but I think we should also do the same for m_htClickedItem, shouldn't we?

I'll apply the obvious generalization of this patch for both of them soon if there are no objections.

  • Resolution set to fixed
  • Status changed from confirmed to closed

(In [63170]) Invalidate stored wxTreeItemIds when the corresponding item is deleted in wxMSW.

m_htSelStart and m_htClickedItem stored in wxTreeCtrl must be invalidated when
the item they point to is deleted (which also happens when all the items are
deleted), otherwise the selection doesn't behave correctly after doing it.

Closes #11619.
