Re: [pygtk] GtkCTree
On Sat, 27 May 2000, James Henstridge wrote: 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']) node4 = tree.insert_node(node2, node3, ['another subitem']) OK, I tried that, and I get a tree with two visible nodes, and no way to expand the second node. So, I was poking around the GTK+ documentation, and that turned up nothing, so I poked through the gtk.py file, and found that node2 when created above defaults to being a leaf, and apperently you have to manually tell it that it isn't a leaf. Here is the way the node2 = line should read (this is probably clunkier than it needs to be, but I'm very new to python): node2 = MyTree.insert_node(None, None, ['another item'], 5, None, None, None, None, FALSE) The 5, followed by the 4 Nones are the default parameters for various optional parameters (due to being very new to python, I wasn't sure how to set the last parameter in the parameter list without having to set the prior ones. The FALSE says that this node isn't a leaf (leaf nodes obviously should say TRUE there). Maybe everyone in the world but me knew this, but I thought I'd post it anyway just in case.

[pygtk] Default button
I have a simple form with a GtkEntry and two button (ok/cancel). I want that the ok button is the default button (activate with the enter key) and that the Entry has the focus when the form is showed. I write this code: file_entry.grab_focus() ok_button.set_flags(CAN_DEFAULT) ok_button.grab_default() But if the "file_entry" has the focus the ok_button isn't the default. Someone can help me?

[pygtk] string.atof(str) causing problems in xmlparse.py
Hi there,
being mostly new to python and this list, i do not
want to miss the opportunity to report a strange
behavior:
string.atof('0.5') is valid when used by itself.
However, when processing my glade-file in
xmlparse.py it is causing problems:
[...]
File "/usr/lib/python1.5/site-packages/pyglade/build.py", line 83,
in __new_widget
widget = create(node)
File "/usr/lib/python1.5/site-packages/pyglade/build.py", line 225,
in label_new
misc_set(label, node)
File "/usr/lib/python1.5/site-packages/pyglade/build.py", line 214,
in misc_set
xalign = info.get_float('xalign', 0.5)
File "/usr/lib/python1.5/site-packages/pyglade/xmlparse.py", line
88, in get_float
return string.atof(self.__tags[key])
ValueError: invalid literal for atof(): 0.5
this seems quite strange to me. only to me?
if this is a bug, i can not see why i should be the first to
encounter.
cheers, christian folini

[pygtk] Ctree bug
Hi all,
When using Ctree trying to read text from the 0th row, pygtk
generates an execption.
However, if I access row 1 and above things work fine.
I have data in row zero, so what's wrong?
Here's the stack trace. I've included the test program. (select a row
to see it crash.)
[ezolt@pulitzer test]$ python hello.py
Traceback (innermost last):
File "/usr/lib/python1.5/site-packages/gtk.py", line 125, in __call__
ret = apply(self.func, a)
File "hello.py", line 12, in on_epoch_tree_tree_select_row
print tree.node_get_text(node, 0)
File "/usr/lib/python1.5/site-packages/gtk.py", line 1412, in node_get_text
return _gtk.gtk_ctree_node_get_text(self._o, node, col)
ValueError: can't get text value
