Is this possible to draw GtkTreeView listed like GtkIconView?

I am working on a GTK+ application written in python. I obviously use PyGtk. My application is about collections of videos. It's a kind of F-spot or Picasa, but for video.

As you can see in these two apps, you have a central area where you can see all of your photos with tag thumbnails under.

In my app, I want to implement the same kinf of view. For now I simply use this:

A gtk.Table containing a VBox, inside the VBox a Pixbuf (my video thumbnail) and a HBox, and inside the HBox, as many Pixbuf as tags.

It's working but it's ugly and It seems like It's not the better solution.

Looking deeply in the docs, I have found two widgets near my neeeds: IconView and TreeView. But IconView can only display one pixbuf per "row" and TreeView don'开发者_如何学Got display as a grid like IconView.

My question: Is there a way to display a TreeView like an IconView (in a grid) ? How would you implement the F-spot way of arranging photos and tags under?

IconView is what you need. In the ListStore every row represent just one pixbuf but the IconView adjusts the images in a grid. Here a small example, launch it with the image files you want to show as arguments, for example:

python example.py /usr/share/icons/hicolor/16x16/apps/*

.

import sys
import gtk


store = gtk.ListStore(gtk.gdk.Pixbuf)
iv = gtk.IconView(store)
iv.set_pixbuf_column(0)
for arg in sys.argv[1:]:
    pixbuf = gtk.gdk.pixbuf_new_from_file(arg)
    store.append((pixbuf, ))

w = gtk.Window()
w.connect('destroy', lambda w: gtk.main_quit())
sw = gtk.ScrolledWindow()
w.add(sw)
sw.add(iv)
w.show_all()
gtk.main()

The best approach is either to stick with a table and reimplement selections or Use a custom version of IconView with a custom cellrenderer wich can take gtk.HBox().

Some guidelines about custom cellrenderer are :

a discuss occured on pygtk mailing list :

WWWalter make a sample code : http://www.translate.org.za/blogs/walter/en/content/conquering-cellrendererwidget

According to Ruben Vermeersch, f-pot use a modified version of IconView. Code can be found here : http://git.gnome.org/browse/f-spot/?h=icon-view-cleanup
