25 // This is an experimental GTK theme.
26 //
27 // Comments:
28 // - For now we would keep all the themes in the same assembly to have
29 // handy the internals methods.
30 // - We are using Pinovoke for now to access GTK/GDK to avoid adding
31 // gtk-sharp as a SWF dependency
32 // - The ThemeGtk comes from ThemeWin32Classic, we use it as the default
33 // implementation for the methods that we are not taking care of.
34 // - When GDK is initialised it opens its own display. There is not way of changing it,
35 // then we use that display as SWF display
36 // - You can activate this Theme in Linux doing export MONO_THEME=gtk
37 // - GTK paints controls into a window no a device context. We should inverstigate if we
38 // we can encapsulate a dc in a gtkwindow.

44 // - Streamlined Theme interfaces:
45 // * Each DrawXXX method for a control now is passed the object for the
46 // control to be drawn in order to allow accessing any state the theme
47 // might require
48 //
49 // * ControlPaint methods for the theme now have a CP prefix to avoid
50 // name clashes with the Draw methods for controls
51 //
52 // * Every control now retrieves it's DefaultSize from the current theme
53 //
54 // Revision 1.5 2004/09/02 16:32:54 jordi
55 // implements resource pool for pens, brushes, and hatchbruses
56 //
57 // Revision 1.4 2004/08/24 18:37:02 jordi
58 // fixes formmating, methods signature, and adds missing events
