Hi.
Each row in my TreeView contains a column with: toggle, pixbuf and
text renderer respectively. If need to maintain the following
situations:
- user clicks on the toggle - toggle receives 'toggled' event;
treeview row cursor should not change.
- user clicks on the rest of the row (pixbuf, text) - treeview row
cursor should change, toggle should not receive 'toggled' event.
The program does not work as I expected. I receive 'toggled' and
'cursor-changed' events no matter what part the user clicks. If the user
clicks on the toggle, the treeview row cursor changes to the row clicked
toggle is in.
The following code sets up the TreeView (SETS_COL_TOGGLE is 0,
SETS_COL_ICON is 1, SETS_COL_NAME is 2).
store = gtk.TreeStore( bool, gtk.gdk.Pixbuf, str, int )
col = gtk.TreeViewColumn( 'Sets' )
# Toggle.
cell = gtk.CellRendererToggle()
cell.set_property( 'activatable', True )
cell.connect_object( 'toggled', self.on_set_toggled, store )
col.pack_start( cell, False )
col.add_attribute( cell, 'active', SETS_COL_TOGGLE )
# Pixbuf.
cell = gtk.CellRendererPixbuf()
col.pack_start( cell, False )
col.add_attribute( cell, 'pixbuf', SETS_COL_ICON )
# Text.
cell = gtk.CellRendererText()
col.pack_start( cell, True )
col.add_attribute( cell, 'text', SETS_COL_NAME )
self.treesets.append_column( col )
self.treesets.set_model( store )
I successfuly set up this kind of tree behavior using Qt, I'm fighting
Gtk right now.
Any kind of suggestion would be appreciated.
you need to check the path in the toggled callback to see if it is on
the toggle.
Here is some code from our app that uses several columns in a treeview,
one of which is a toggle (not always shown/used for some views). Sorry,
I wasn't the one that originated this code and I have not worked on it
lately. You should be able to figure out what you need from it and the
embedded comments.

# Note! this is a gtk.TreeView type class and swap out the treeview
models

self.connect(button_press_event, self.on_button_press)

self.event = event # save the event so we can access it in _clicked()

on_button_press() callback...)

displayed.
