Hi!
I´ve read alle the examples, and wow, this widget isnt easy.
My problem is, that I need to create a TreeStore with Objects defined
in Class Type...
But which Object is an Image? - Is it O.K. to use a Image, I dindt find
any useful Pixbuf-stuff
I tried it with several types, but I only became this:
(java-gnome:1653): Gtk-WARNING **: gtktreestore.c:801: Unable to convert
from gpointer to GObject
I´m really frustrated, I want to learn Java-GTK, but some parts are so
counterintuitive, I dont really understand this widget..
Has anybody already written an app using images in Treeview? Some
sourcecode would help extremly....
Sorry, but I really, really read very much documentation...
thx Linuxhippy
It only says
