Re: GDK_POINTER_MOTION_HINT_MASK has no effect

This is the paradigm I use in all my drawing apps that has served me well: 1) Do all drawing to one or more background pixmaps. 2) Do all drawing in routines separate from your configure handler or your expose handler. 3) Call your drawing routine(s) from the configure handler. 4)

Paul, Thanks for the information, it's good to learn about how GTK+ does its double buffering in detail. However... On Nov 29, 2007 5:22 PM, Paul Davis [EMAIL PROTECTED] wrote: And this particular case is wholly not addressed in code sample 1; there, you must redraw the entire

Re: GDK_POINTER_MOTION_HINT_MASK has no effect

Hi, I'm not really sure what *is_hint* is intended to provide, but anyway, what you are trying to achieve is totally possible without its use (if I understand you properly). Going on the assumption I do understand what you are trying to achieve, I am providing below some code to illustrate this.

PNG image creation without a physical display

or program? Or am I missing something obvious here (which I hope)? thanks for any tips or pointers, this is really the final open question that will make the system I've been developing for the last three years (graphically, at least) complete. cheers, richard boaz

Gdk GC and Associated Colormap

Re: g_option_context_parse under cron execution

Yes, I've fully debugged the cron-executed version. All arguments are identical to when executed from the command line, i.e., are properly constructed and fully valid. I was wondering, too: Does this particular glib routine require there be a display available? Still, I would expect the error

Re: g_option_context_parse under cron execution

Hi John, Thanks. Going through the exercise of providing a small example, the cause of the problem became known: I had included the following call when setting up the context: g_option_context_add_group (context, gtk_get_option_group (TRUE)); as indicated in the documentation example.
