Re: Using By-Value Compound Getters (Re: gtk_widget_get_allocation)
I think that using pass-by-value struct will bring more headache for language bindings developers, because this complicates ABI and not every language's foreign function interface supports passing structs by value. (I think that passing structs by value is not part of C language, but of C++ (or am I wrong?), so it is problematic to support) I would support having both kinds of accessors: "simple" ones (option "a") and convenient for C (option "b"). Just the same as with other kinds of functions, e.g., g_object_get and g_object_get_property. One part of interface for convenience of C programming, one part for convenience of other languages. signature.asc Description: This is a digitally signed message part. ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list

Is it just the button that's getting the redraw > or something else? Button-*-event signal is raised not when pressing and releasing GtkButton (the widget on the screen), but when pressing and releasing button of a mouse. So, e.g., mouse clicks on form => form redrawn twice. signature.asc Description: This is a digitally signed message part. ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list

This method will thread-safe. I think that this is much easier than pipes. Or you can call gdk_threads_enter/gdk_threads_leave and call gtk functions normally. > > I also saw that it could be a visual studio issue in this thread > http://mail.nl.linux.org/xchat-discuss/2004-03/msg00177.html > > Any suggestions? signature.asc Description: This is a digitally signed message part. ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
