GtkImage with animation: animation stops when all frames are shown
Hello. I create GtkImage with animation: GdkPixbufSimpleAnim *anim = gdk_pixbuf_simple_anim_new (w, h, RATE); gdk_pixbuf_simple_anim_add_frame (anim, pixbuf1); gdk_pixbuf_simple_anim_add_frame (anim, pixbuf2); gdk_pixbuf_simple_anim_add_frame (anim, pixbuf3); ... GtkWidget *image = gtk_image_new_from_animation (GDK_PIXBUF_ANIMATION (anim)); But when i display it animation stops when all animation frames are shown, but i want to have a circular animation. It looks that I should use some g_timeout_add (...) or anything else. Can someone help me with? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Virtual list boxes (using GtkTreeView or other)
Hello, I have been googling for some form of virtual list boxes, but can't seem to find any reference. How people do with very large list boxes? I was hopping I could have some form of just seting up the column headers and say I have 1 rows and let the widget ask me for the data when it needs it. It seems a bit heavy to add 1 rows one at a time, as it seems I'm forced to do even if I derive my own ListStore. Any hints?

The gdk_pixbuf routines do not support saving exif data. You would need to save your jpeg file, then use libexif, exiv2, or another library to write the exif data to the jpeg (i.e., a second file write). gThumb, for example, uses libexif. - Mike ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: cross compiling and ld auto-import errors
Never mind, I solved it. There were a few g_mutex_lock/unlock calls in the code and that seemed to be the problem. I replaced them with gdk_threads_enter() and gdk_threads_leave() (after ensuring that g_threads_init() and gdk_threads_init() were both called) and the linker was much happier. -Bethany On Fri, 2007-06-01 at 10:43 -0400, Bethany Seeger wrote: Hi, I'm cross compiling a linux application to work on Windows using i586-mingw32msvc-gcc.

Make the drawing area repaint (e.g. with gtk_widget_queue_draw())
and just do not draw anything there in the expose-event
handler this time.

Since GtkAboutDialog is a subclass of GtkDialog, it is intended to be used as a modal dialog. Hence, you would do something like: gtk_dialog_run(about_dialog); gtk_widget_hide(about_dialog); Also, see http://developer.gnome.org/doc/API/2.0/gtk/GtkAboutDialog.html#gtk-show-about-dialog Samuel On 6/2/07, John Zoidberg [EMAIL PROTECTED] wrote: Hi, I have a problem with the gtk about dialog: When I click on the Close button it doesn't close.
