Subject: Send wxEVT_COMMAND_DATAVIEW_CACHE_HINT to proper window.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/99f44d9704f7a45fb4ee627336798eae4c941a1e

Send wxEVT_COMMAND_DATAVIEW_CACHE_HINT to proper window.

The event was sent to wxDataViewCtrl parent instead of the control itself for
some reason, fix this.

Closes #13020.
