From 8ec46846f6af0da23a1a42f345e40f517ba8f005 Mon Sep 17 00:00:00 2001 From: Alexander Sulfrian Date: Fri, 14 Sep 2012 22:31:38 +0200 Subject: utils: add activator helper The activator should be used to encapsulate activatable objects. It calls enable on construction and disable on deconstruction. It should be used for example to enable some opengl settings, while the activator object is used in local scope. It ensures, that the opengl setting get disabled, if the scope is left even when throwing an exception. --- src/utils/activatable.hpp | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 src/utils/activatable.hpp (limited to 'src/utils/activatable.hpp') diff --git a/src/utils/activatable.hpp b/src/utils/activatable.hpp new file mode 100644 index 00000000..0142ee0d --- /dev/null +++ b/src/utils/activatable.hpp @@ -0,0 +1,38 @@ +/* + * UltraStar Deluxe - Karaoke Game + * + * UltraStar Deluxe is the legal property of its developers, whose names + * are too numerous to list here.
