To put this in context, it's for auto-previewing audio files. The simple implementation causes an audio file to be previewed when gtk_dialog_run is called* or when the current folder is changed in the chooser. By using a "dont_preview" boolean and connecting the "current-folder-changed" signal to a callback I can then use g_timeout_add to cancel the "dont_preview" flag. The flag must be set before gtk_dialog_run is called, and will always be set when the folder is changed. *provided the item initially selected in the chooser is an audio file. > Is this normal? Is there a more standard way of doing this? I'm guessing it is normal/standard and that work-a-rounds are necessary if you want to do something like this. > > I'm using GTK 2.24.10 in 64bit Arch Linux. > > Thanks, > James. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
