Subject: Fix child selection in multi-selection generic wxTreeCtrl.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/59cd3bbd6c35a797b3ddbd268a49cfc844b2b639?ds=inline

Fix child selection in multi-selection generic wxTreeCtrl.

The children which are not currently shown on the screen shouldn't be affected
by Shift-selecting in multi-selection control.

Closes #1312.
