problem: so im using a GdkPixmap as a backend for a GtkImage. the problem im having is that they are not redrawing. hell, i dont know if they are ever drawing. im not loading from an image file, the pixmap is created manually. additionally, the pixmap gets altered and the GtkImage needs to be able to be updated at anytime. i know it's not the non-Gtk stuff because it worked fine when i was using a GtkDrawingArea. the API documentation is a little vague about GtkImages with GdkPixmaps especially since it didnt mention that GtkImage has no "window" which breaks the fake OO. ive posted pertainent code here because you need it to figure out what im really doing: http://pastebin.com/533165
background info: i dont know about Gtk's "referencing" system as it's not documented, as far as i know. additionally, there are no tutorials for GtkDrawingArea and GtkImage. i think the referencing may be part of this issue because it is mentioned on the GtkImage API documentation page but i really dont know as it's completely alien to me. why im not (still) using GtkDrawingArea: i had previously used a GtkDrawingArea (and it worked) but i ran into a few problems. first, it does not allocate the memory for the image until it was exposed. i used a Insight, my gdb based debugged to verify this. all functions to invalidate/expose it failed to be effective at all. second, i have to draw on it when a file is loaded which can come before it is ever exposed. third, i really cant afford to use a pixmap buffer or something because my image is 64MB in size and is in an encoded format which is too slow to be decoded on the fly. also, about 28MB of the image can be displayed at once so using a buffer is still a bad idea. with this major pain in the ass i have to use a pixmap in combonation with a GtkImage because it does not copy the data at all. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
