[pygtk] Need help with pixbuf's in treeview

[The Midnight Coder]

Hi. I need some help getting pictures to be shown in a treeview row. After some searching I found that the only way to do this is by using Pixbufs. I tried getting it to work but no luck so far :(

Can someone help me. This is the code:



self.liststore = gtk.ListStore(gtk.gdk.Pixbuf, str, str)

self.treeview = gtk.TreeView(self.liststore)
self.treeview.set_size_request(20,380)
self.treeview.set_headers_visible(False)

self.column = gtk.TreeViewColumn('Pixbuf')
self.column1 = gtk.TreeViewColumn('Text')

self.img1 = gtk.gdk.pixbuf_new_from_file("file.jpg")

self.liststore.append([self.img1, True, 'Text'])

self.treeview.append_column(self.column)
self.treeview.append_column(self.column1)

self.cellpb = gtk.CellRendererPixbuf()
self.cell1 = gtk.CellRendererText()

self.column.pack_start(self.cellpb, True)
self.column1.pack_start(self.cell1, True)

self.column1.set_attributes(self.cell1, text=2)

Quick example (change image file names as appropriate):


#!/usr/bin/env python

import gtk

window = gtk.Window()

liststore = gtk.ListStore(gtk.gdk.Pixbuf)
for f in ["img1.jpg", "img2.jpg", "img3.jpg"]:
i = gtk.gdk.pixbuf_new_from_file(f)
liststore.append([i])

treeview = gtk.TreeView(liststore)
cell = gtk.CellRendererPixbuf()
column = gtk.TreeViewColumn("Pixbuf", cell)
column.add_attribute(cell, "pixbuf", 0)
treeview.append_column(column)

window.connect("destroy", lambda w: gtk.main_quit())

window.add(treeview)
window.show_all()

gtk.main()

From the looks of the code you posted, you were missing the attributes method on the pixbuf column.

In most cases, the following steps are required to setup TreeView's (and is often the part that trips people up as they forget one of them, or get them in the wrong order):


Create the model
Create the treeview and attach model
Setup the appropriate cells
Specify and attach the columns to the TreeView
Attach the cells to columns
Specify the column/cell attributes

Wow thanks. That did the trick. I'll keep that list in mind because its simple. I had ended up combining alot of examples I had tried to get the treeview to work but after the headache I went through I won't be doing that again.

Thanks steeleyuk, that really helped!
