From fa174461abdc5c33de16428109c7d46b4f150093 Mon Sep 17 00:00:00 2001 From: Jaakko Keränen Date: Thu, 18 Mar 2021 11:26:11 +0200 Subject: Scrollbar fading and periodic commands Added a new mechanism to issue periodic but not per-frame commands. This is used for main-thread operations like checking if it's time to fade away the scrollbars. Scrollbars are faded away completely on Apple platforms. Adjusted list right margins accordingly. --- src/periodic.h | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 src/periodic.h (limited to 'src/periodic.h') diff --git a/src/periodic.h b/src/periodic.h new file mode 100644 index 00000000..acb00aa2 --- /dev/null +++ b/src/periodic.h @@ -0,0 +1,39 @@ +/* Copyright 2021 Jaakko Keränen + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are met: + +1.
