+ + * Size negotiation. Basically make sure this works. It should be no + different than the usual GtkWidget size request/allocation. The + applets shouldn't be allowed to be any bigger than the panel. The + other issue is with applets that want to expand to fill the available + space on the panel. At the moment this is solved with getExpandFlags, + but this ends up with some freaky stuff going on when you're moving + applets. Maybe we should consider having a re-sizable flag which would + make the applets have grabs for re-sizing. diff --git a/libmate-panel-applet/libmatepanelapplet-3.0-uninstalled.pc.in b/libmate-panel-applet/libmatepanelapplet-3.0-uninstalled.pc.in new file mode 100644 index 00000000..40f02130 --- /dev/null +++ b/libmate-panel-applet/libmatepanelapplet-3.0-uninstalled.pc.in @@ -0,0 +1,11 @@ +prefix=@prefix@ +exec_prefix=@exec_prefix@ +libdir=@libdir@ +includedir=@includedir@ + +Name: libmate-panel-applet-3 +Description: libmate-panel-applet-3 +Requires: glib-2.0 mateconf-2.0 gtk+-2.0 +Version: @VERSION@ +Libs: ${pc_top_builddir}/${pcfiledir}/libmate-panel-applet-3.la +Cflags: -I${pc_top_builddir}/${pcfiledir} diff --git a/libmate-panel-applet/libmatepanelapplet-3.0.pc.in b/libmate-panel-applet/libmatepanelapplet-3.0.pc.in new file mode 100644 index 00000000..97fee38a --- /dev/null +++ b/libmate-panel-applet/libmatepanelapplet-3.0.pc.in @@ -0,0 +1,11 @@ +prefix=@prefix@ +exec_prefix=@exec_prefix@ +libdir=@libdir@ +includedir=@includedir@ + +Name: libmate-panel-applet-3 +Description: libmate-panel-applet-3 +Requires: glib-2.0 mateconf-2.0 gtk+-2.0 +Version: @VERSION@ +Libs: -L${libdir} -lmate-panel-applet-3 +Cflags: -I${includedir}/mate-panel-3.0/libmate-panel-applet diff --git a/libmate-panel-applet/mate-panel-applet-factory.c b/libmate-panel-applet/mate-panel-applet-factory.c new file mode 100644 index 00000000..96eab326 --- /dev/null +++ b/libmate-panel-applet/mate-panel-applet-factory.c @@ -0,0 +1,263 @@ +/* + * mate-panel-applet-factory.c: panel applet writing API. + * + * Copyright (C) 2010 Carlos Garcia Campos + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Library General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
