Hello All,

Heres the scenario.
I populate my combobox (in my treeview) dynamically and want to display it in
more than one column if the list is large.
This is how I set it up :
model = gtk.Liststore(str)
tree_store_col = 0
cell_renderer = gtk.CellRendererCombo()
cell_renderer.set_property("model",model)
cell_renderer.set_property('text-column', 0)
cell_renderer.set_property('editable', True)
new_col = gtk.TreeViewColumn(col_name, cell_renderer, text=tree_store_col)
tree.append_column(new_col)
cell_renderer.connect('editing-started', populate_combo, (tree_store,))
And this is how I populate the combobox in the populate_combo callback
def populate_combo(self, cell, editable, path, data):
store = data[0]
iter = store.get_iter(path)
items = self.get_list() # my function get_list() returns a list of strings
m = cell.get_property('model')
m.clear()
items.sort()
for s in items:
m.append([s])
so if my items list is large, it gets frustrating to scroll the entire list to
get to the required item. It would be nice if the items were displayed in more
than one column (for eg.)
Any suggestions on how to make this better?
In populate_combo() the ComboBox is the "editable" param so
editable.set_wrap_width(width) should allow you to display the items in
multiple columns.

Re: [pygtk] Win32 file chooser
FWIW, one small step further: here is a short script that will show the
Windows dialog on windows if possible, and fall back to the PyGTK one
where necessary (on Linux or on Windows without win32all). See attached.
It's only designed for opening files at this stage, but perhaps it can
be taken further.
Cheers

[pygtk] Drag and drop: retaining selection?
I'm trying to set up DnD in my program to retain the selection after dragging, but I can't seem to get it work. We have some rather crazy code to handle the drag and drop itself (which I can paste but I don't think it's relevant) because the TreeModel simply mirrors a backend list which we have to update. In Glade, I've connected 'drag-end' to my after_drag_drop callback, and set it to call *after*. Here's the callback: def after_drag_drop(self, treeview, drag_context): model = treeview.get_model() sel = treeview.get_selection() # self._selected is created in the DnD code, and is simply a list of selected paths. for path in self._selected: sel.select_path(path) The treeview's selection mode is set to gtk.SELECTION_MULTIPLE. It seems like it works (just eyeballing it), because the selection 'sticks' for a moment, but then the selected rows are unselected. Any idea what would be causing this or what other code I could paste to help figure this out?

new_col = gtk.TreeViewColumn(col_name, cell_renderer, text=tree_store_col)
tree.append_column(new_col)
cell_renderer.connect('editing-started', populate_combo, (tree_store,))

items = self.get_list() # my function get_list() returns a list of strings

[pygtk] Taking action when a window is raised
[I'm re-posting this from http://www.gnomedev.com/viewtopic.php?t=36] Hi there. I'm trying to work out how to run a callback when my application's main window is given top level focus. I'm using PyGTK, but I think my question is really a general GTK+ one. How are you supposed to do it? I can't find a signal on a GtkWindow that I could connect to, which has left me stumped. I'm not sure how else it would work. I know it's possible (the wonderful gossip [http://live.gnome.org/Gossip] does it), but a cursory scan of the source didn't reveal anything obvious (to me). Any pointers? Cheers, Graham ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
