From: Taehyub Kim Date: Tue, 22 Dec 2020 09:09:22 +0000 (+0900) Subject: DnD: Make the accepted callback of elm_drag_start working correctly X-Git-Tag: accepted/tizen/unified/20210104.130306~6 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F49%2F250249%2F2;p=platform%2Fupstream%2Fefl.git DnD: Make the accepted callback of elm_drag_start working correctly problem: The accepted callback of elm_drag_start always returns 0 solved: The accepted callback will be return 1 when drag and drop is finished successfully. (When the drag data is sent) Change-Id: Id877b3f39b1634128fa453d99cde20bd6e44806a --- diff --git a/src/lib/ecore_evas/Ecore_Evas.h b/src/lib/ecore_evas/Ecore_Evas.h index 886b29d..8afc2bd 100755 --- a/src/lib/ecore_evas/Ecore_Evas.h +++ b/src/lib/ecore_evas/Ecore_Evas.h @@ -4081,6 +4081,15 @@ EAPI Eina_Future* ecore_evas_selection_get(Ecore_Evas *ee, unsigned int seat, Ec typedef void (*Ecore_Evas_Drag_Finished_Cb)(Ecore_Evas *ee, unsigned int seat, void *data, Eina_Bool accepted);
