[pygtk] GtkCTree: Right-click on a node?
Greetings! I am in the process of migrating a tool from a GtkTree to a GtkCTree. One of the things the old GtkTree used to do was catch right-clicks on the tree elements, which it used to pop-up an input dialog. I'm trying to implement the same functionality in the GtkCTree, but it seems there are no node-level signals available, because the GtkCTreeNode objects are not themselves widgets. I can catch the button-press-event for the GtkCTree as a whole, and test the event structure for right-click-ness, but it's not obvious to me how to go from a tree-level click event to a node. I am reluctant to make right-clicking operate on the selected node, because I am already using selection state to convey other information. I've gone a couple of rounds with the documentation, in case there is a widget hidden inside the GtkCTreeNode, but this does not appear to be the case. Anyone have any good clues? -- Andrew Reid [EMAIL PROTECTED] ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

[pygtk] GtkCTree not updating
I've got a weird problem with GtkCTree, and before I tell you what it is I'll say that I'm using Python2.2aX and pyGTK 0.6.8. I know, but it's working fine for the most part, I'm developing for a pyGTK-release running system (Linux on iPAQ), and I can't get the beta of pyGTK1.99 to compile because of failed dependancies (pkg-config? pango? it can't find glib, but I have it installed, blahh). If this is going to cause the problem, you needn't read further- just yell at me to upgrade :). Oh, all the structures I'm using are those from Python2.0- there's no 2.2 specific stuff in this one. Quick problem synopsis: CTree built recursively from a dictionary (dict is in instance, ie self.dict) in a method of a single class. When I update the dictionary, freeze() or clear() the tree, then rebuild the tree with the same method that originally built the tree, it freezes and trips out (words write on top of words in the tree, branches disappear, etc.) If I freeze() or clear() the tree, then add a node manually, it works fine. If I don't return to the original method, but update the dictionary manually, it freezes. I need a way to update both the tree and dictionary, or otherwise keep them in sync, because the tree should reflect changes over multiple runs of the program (It's an expense tracker/calculator). If this is the wrong way to do it, I guess I can make all changes to the tree directly and figure out a method to dump the tree to a file. I'll send code if needed, but thought this might be a conceptual error on my part, rather than a programming error. Hmm, just thought of something... can I pickle a CTree and load it on the next startup, thereby eliminating the need for the dictionary altogether? I know that *technically* I can, because Pickle can handle arbitrary data types, but can I from a pyGTK perspective. Not handling the dictionary at all would save a lot of code!

Am i missing something obvious? You are using the wrong method: to attach data to a row in a GtkCTree, you need to call ctree.node_set_row_data(node, "hey") ^ By the way, you will have something much better if you insert your nodes using a list of labels, as in: node = ctree.insert_node(None, None, ['hey']) (a GtkCTree can have multiple columns, and you need to provide a list of strings to insert a new item. By default, there is only one column, and it is the tree column, so a one element list is fine) Cheers Alexandre, who might have been asking the same question just one month ago... -- Alexandre Fayolle http://www.logilab.com - "Mais où est donc Ornicar ?" - LOGILAB, Paris (France). ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk

For the GtkCTree, you don't use GtkTree of GtkTreeItem widgets. Instead,
you create the items in the tree with the insert_node method.
tree = gtk.GtkCTree(1, 0)
node1 = tree.insert_node(None, None, ['an item'])
node2 = tree.insert_node(None, None, ['another item'])
node3 = tree.insert_node(node2, None, ['a subitem'])

[pygtk] GtkCTree
I've been trying to play a bit with GtkCTree, and I can't seem to get anything useful out of it. Does anyone have small sample code which displays a GtkCTree? Thanks. -- Moshe Zadka <[EMAIL PROTECTED]>. INTERNET: Learn what you know. Share what you don't. To unsubscribe: echo "unsubscribe" | mail [EMAIL PROTECTED]

Thankyou very much for the quick response. Seeing your answer I realise now that it was a stupid question and I should have paid more attention to the chain of inheritance before posting. I'll try to be a bit less daft in the future :) Thanks again, -Rob To unsubscribe: echo "unsubscribe" | mail [EMAIL PROTECTED]

[pygtk] GtkCTree in a GtkScrolledWindow strange behaviour
I was wondering if anybody could explain how a GtkCTree goes about
deciding how wide it is? (Or more to the point, how to make one only
be as wide as it needs to be, to contain its contents -- I'd like to
be able to place one inside a scrolled window and have the horizontal
scrollbar represent the width of the contents -- which of course is
what normally happens automatically with most widgets.)
Furthermore, something strange happens if you put one inside a
GtkScrolledWindow with POLICY_AUTOMATIC set on the scrollbars: each
time you expand and collapse the tree, it gets wider! Can anybody
shed light on this oddity?
(Also, is it a bug that the text argument to GtkCTree.insert_node is
seemingly truncated after the first character?)
The following script is sufficient to demonstrate the width-altering
behaviour:
#! /usr/bin/env python
from gtk import *
win = GtkWindow()
tree = GtkCTree()
tree.show()
basenode = tree.insert_node(None,None,'base',expanded=TRUE,is_leaf=FALSE)
tree.node_set_text(basenode,0,'base') #otherwise we only get 'b' (???)
for name in map(str, range(100)):
n = tree.insert_node(basenode, None, " ")
tree.node_set_text(n, 0, name)
for node in tree.base_nodes():
tree.sort_recursive(node)
treewin = GtkScrolledWindow()
treewin.set_policy(POLICY_AUTOMATIC, POLICY_AUTOMATIC)
win.add(treewin)
treewin.add(tree)
treewin.show()
win.connect("delete_event", mainquit)
win.show()
mainloop()
Thanks,
