Re: [pygtk] [Fwd: Using cairo to shape windows]
I have changed it to be a simple window with a HScale slider in the
middle to dictate how round the edges are, so that it might actually be
a demonstratable application, as per pachi's request. Additionally, the
window when resized will scale and maintain the rounding of the corner.

It sounds like that may be able to do what you would like. Or at least part way to what you are trying to achieve. -- Brian <[EMAIL PROTECTED]> ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
Re: [pygtk] [Fwd: Using cairo to shape windows]
I have modified it slightly in order to expunge the last traces of
gdk.GC and gdk.draw_* APIs, which are now deprecated.
Cheers.

[pygtk] User defined interface
Hi First I'm new to Python and PyGTK, but I have used Gtk for some years now. Currently I'm making an application with PyGTK. The application is supposed to show some data that is read from an XML file. Now what I need is to give the user the flexibility that she/he can set up how she/he wants the display widget to look like. My idea is to use a table widget as the base and that the user can put Labels, Pixmaps, and choose where in the table to display the data (and later also be able to edit data). So my question is: Given that the layout is defined in an XML file is it better to: 1. in some way (if possible) to use libglade to read a XML file that doesn't have a main window but only a Table widget as the base? As the layout will change depending on what data to display. 2. make ones own parser to read and generate the display GUI from the XML structure. I'm also thinking that later when I want to add edit capabilities I need to hook callbacks to the different edit widgets and that may be easier without libglade 3. or has somebody already made something like this that is available in as a library or similar? The program will be licensed as GPL or BSD if finished. Thanks in advanced for any hints.
