Hi,
I have made progress, i use this function to make the resize: pixbuf =
gdk_pixbuf_scale_simple(pixbuf, widget->allocation.width,
widget->allocation.height, GDK_INTERP_BILINEAR);
This works, but application blocks after a while..
Here is the Expose event function:
void on_layout_Home_expose_event(GtkWidget *widget, GdkEvent *event,
gpointer user_data){
GtkAllocation allocation;
GtkWidget *homeWindow;
GdkPixmap *background;
GtkStyle *style;
pixbuf = gdk_pixbuf_scale_simple(pixbuf, widget->allocation.width,
widget->allocation.height, GDK_INTERP_BILINEAR);
gdk_pixbuf_render_pixmap_and_mask (pixbuf, &background, NULL, 0);
style = gtk_style_new ();
style->bg_pixmap[0] = background;
gtk_widget_set_style (GTK_WIDGET(widget), GTK_STYLE(style));
return TRUE;
}
Thanks
