From: Carlos Lopez Date: Wed, 22 Jul 2009 18:05:34 +0000 (+0200) Subject: If press ALT while dragging it performs a SetKeyframeDelta operation. X-Git-Url: https://git.pterodactylus.net/?a=commitdiff_plain;h=47baca24f2eaa508d5f39a524fed0e910a0e45c9;p=synfig.git If press ALT while dragging it performs a SetKeyframeDelta operation. Maybe someone prefer to use the right mouse button but want to reserve for pop up menu. --- diff --git a/synfig-studio/trunk/src/gtkmm/widget_keyframe_list.cpp b/synfig-studio/trunk/src/gtkmm/widget_keyframe_list.cpp index b30632e..a350aa1 100644 --- a/synfig-studio/trunk/src/gtkmm/widget_keyframe_list.cpp +++ b/synfig-studio/trunk/src/gtkmm/widget_keyframe_list.cpp @@ -50,7 +50,7 @@ using namespace studio; /* === M A C R O S ========================================================= */ - +#define WIDGET_KEYFRAME_LIST_DEFAULT_FPS 24.0 /* === G L O B A L S ======================================================= */ /* === P R O C E D U R E S ================================================= */ @@ -58,20 +58,20 @@ using namespace studio; /* === M E T H O D S ======================================================= */ Widget_Keyframe_List::Widget_Keyframe_List(): - editable_(true), - adj_default(0,0,2,1/24,10/24), - adj_timescale(0), - fps(24), + adj_default(0,0,2,1/WIDGET_KEYFRAME_LIST_DEFAULT_FPS,10/WIDGET_KEYFRAME_LIST_DEFAULT_FPS), kf_list_(&default_kf_list_), - time_ratio("4f", fps) + time_ratio("4f", WIDGET_KEYFRAME_LIST_DEFAULT_FPS) { + adj_timescale=0; + editable_=true; + fps=WIDGET_KEYFRAME_LIST_DEFAULT_FPS; set_size_request(-1,64); //!This signal is called when the widget need to be redrawn signal_expose_event().connect(sigc::mem_fun(*this, &studio::Widget_Keyframe_List::redraw)); //!
