I am trying to create a list of item that the user can select 1 row. I would like to allow the user to sort list based on any of the columns. If I uncomment the line in the follow code then the user to sort on any one column. When I do this the focus on the column heading. I want the focus to start on list.
Also is there any easy why to get the height of the column heading. I have the list in a scrolling window and would like to create the window of the correct size make a number of visible in the scroll window. The call to cell_get_size get me the size of a row in the tree. The header is not the same size and I hate putting constant which is not a good thing to do to make the size correct.
scroll = gtk.ScrolledWindow()
scroll.set_policy(gtk.POLICY_NEVER, gtk.POLICY_ALWAYS) for title in self.config['column']:
if 'type' in title:
type_list.append(title['type'])
else:
type_list.append(gobject.TYPE_STRING) self.store = gtk.ListStore(*type_list)
list = gtk.TreeView(self.store)
self.treeView = list
list.connect('row_activated', self.row_activated_event)
list.set_rules_hint(gtk.TRUE)
list.set_headers_clickable(gtk.TRUE)
selection = list.get_selection()
selection.set_mode(gtk.SELECTION_BROWSE) count = 0
for title in self.config['column']:
if 'hidden' in title:
if title['hidden'] != 'no':
count += 1
continue renderer = gtk.CellRendererText()
column = gtk.TreeViewColumn(title['label'], renderer,
text=count)
self.column.append({})
self.column[count]['viewColumn'] = column self.column[count]['columnID'] = count for key in title: self.column[count][key] = title[key] column.set_resizable(gtk.TRUE) column.set_sizing(gtk.TREE_VIEW_COLUMN_GROW_ONLY) # column.set_clickable(gtk.TRUE) # column.set_sort_column_id(count) # column.set_reorderable(gtk.TRUE) list.append_column(column)
if cell_height == None:
(rectangle, cell_x, cell_y, cell_width, cell_height) =
column.cell_get_sizecount += 1
scroll.set_size_request(-1, cell_height * row_count + 4)
self.treeView.show_all()
