*.cs : Added .dll extension to a load of DllImports. * makefile : now can make the project with one make windows and on both NT and Win98. * gdk/Event.cs : Fixed some invalid symbol names and commented out a load of stuff. * gdk/SimpleEvent.cs : Relocated file from unnecessary subdir and fixed several event keyword clashing bugs. Need to relocate the EventArgs class out of here into its own file. Fixed loads of typos. * glib/Object.cs : Killed the Constructor, this should be a purely abstract class. made Events property public until I can fix the Signal proxying system's broken reliance on it. * glib/SimpleSignal.cs : Relocated, namespaces, and named this Class. Loads of bugfixes. Still doesn't work worth a damn, but it builds. * glib/TypeFundamentals.cs : New enum for use in the Value code. * glib/Value.cs : Implemented a more opaque approach with heap allocated memory and g_value_init and friends. Still doesn't work. Will probably switch to a more C# like approach and avoid GValues altogether. * gtk/Button.cs : Commented out some brokeness until I can get around to fixing it later. * gtk/Widget.cs : Commented out a bunch of the new signal stuff until I get around to it. * gtk/Window.cs (Title): using g_object_set until I work out the details of the new Value/SetProperty system. It looks like g_object_set will end up being easier to use via PInvoke. svn path=/trunk/gtk-sharp/; revision=1008
