Thanks for looking into this Lars!
If you wish to see the entire code, see the attachment below,
Otherwise pseudo code is listed below:
[...]
DEFAULT_PATH='~'
RECURSE=1
[...]
Class FileLister()
def __init__(self, path=None):
# Create a new window
[...]
# Create TreeStore & TreeView
self.treestore = gtk.TreeStore(str, gtk.gdk.Pixbuf, int, bool, str)
self.treeview = gtk.TreeView(self.treestore)
# Set TreeView Options
[...]
# Set TreeView Columns
[...]
# Set TreeView Signals
self.treeview.connect('row-activated', self.on_row_activated)
self.treeview.connect('row-expanded', self.on_row_expanded)
# Populate the TreeStore with initial data
self.path = os.path.expanduser(DEFAULT_PATH)
self.dir_walk(path=self.path, recurse=RECURSE)
self.dump_treestore()
# Add Scrolled window with TreeView Object
[...]
# Show Window
[...]
def dir_walk(self, path, parent=None, recurse=RECURSE):
# Populate TreeStore with additional (unique) data
[...]
def on_row_expanded(self, treeview, iter, path):
# PROBLEM:
# (1) Adding in new children data does not enable expanders
model = treeview.get_model()
filename = model.get_value(iter, 4)
self.debug("File : row_expanded(): %s" % filename)
ts = self.dir_walk(filename, parent=iter, recurse=RECURSE)
treeview.set_model(ts) # <== Expanders do not
work for new children!
treeview.expand_row(path, True) # <== Does not seem to work
return
[...]
Kind regards,
Dan
