From: Mikko Rasa Date: Wed, 6 Nov 2013 11:12:24 +0000 (+0200) Subject: Make autosize_special const and add a const autosize overload X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=707b59d45ae50b69c94918f8f74313283b304597;p=libs%2Fgltk.git Make autosize_special const and add a const autosize overload This should reduce useless back-and-forth resizing of widgets in several common patterns. --- diff --git a/source/button.cpp b/source/button.cpp index 8fd2de6..57e5fa4 100644 --- a/source/button.cpp +++ b/source/button.cpp @@ -16,7 +16,7 @@ Button::Button(const std::string &t): set_text(t);
