From 8cffbd694106a2371d297caa008f2290185fed2f Mon Sep 17 00:00:00 2001 From: Matthias Melcher Date: Sun, 21 Jul 2024 13:19:00 +0200 Subject: Adds the FL_AUTO_DELETE_EVENT to suppress auto delete. Language wrappers can have major issues with FLTK auto deleting all children of a group if a group is deleted. This event gives individual widget the opportunity to override auto delete. --- FL/Enumerations.H | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'FL/Enumerations.H') diff --git a/FL/Enumerations.H b/FL/Enumerations.H index d944a13a2..339851d81 100644 --- a/FL/Enumerations.H +++ b/FL/Enumerations.H @@ -407,7 +407,14 @@ enum Fl_Event { // events /** A zoom event (ctrl/+/-/0/ or cmd/+/-/0/) was processed.
