From: Nikita Kitaev Date: Mon, 17 May 2010 03:48:03 +0000 (-0700) Subject: Change transform tool to read key states rather than events X-Git-Url: https://git.pterodactylus.net/?a=commitdiff_plain;h=a5a93271c52a9b4b5eebb8f324d7a2c68f8732be;p=synfig.git Change transform tool to read key states rather than events The code checks if ctrl/alt/shift are pressed any time the mouse moves within the workarea. The checkboxes in the tool options have been replaced with text hints about the shortcuts. --- diff --git a/synfig-studio/src/gtkmm/state_normal.cpp b/synfig-studio/src/gtkmm/state_normal.cpp index 66c7453..7eea702 100644 --- a/synfig-studio/src/gtkmm/state_normal.cpp +++ b/synfig-studio/src/gtkmm/state_normal.cpp @@ -115,30 +115,21 @@ class studio::StateNormal_Context : public sigc::trackable synfigapp::Settings& settings;
