Subject: Return NULL from wxAuiNotebook::GetCurrentPage() if there is no selection.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/b98eb28a50fcb379b1eb52f365cea430cd7a956e

Return NULL from wxAuiNotebook::GetCurrentPage() if there is no selection.

Make it behave as wxBookCtrlBase::GetCurrentPage() and just silently return
NULL instead of asserting if there is no selection.

Closes #13932.
