Subject: Set the data size in wxEVT_COMMAND_DATAVIEW_ITEM_DROP_POSSIBLE in wxGTK.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/167fc10e3bd7a139442d903c05c901a66264089b?ds=sidebyside

Set the data size in wxEVT_COMMAND_DATAVIEW_ITEM_DROP_POSSIBLE in wxGTK.

Allow wxEVT_COMMAND_DATAVIEW_ITEM_DROP_POSSIBLE handler to examine the data
being dragged by setting not only the pointer to it but also its size, as
otherwise it's impossible to do anything with it.

See #12583.
