Can you do something like set_child_packing() to change the packing of
a renderer that was already packed?
That would avoid needing the separate pack_start() call, if it
exists/existed.
Take care,

You are inserting the renderer and several properties into the column using
the column constructor. Later you are using pack_start to reinsert the same
renderer into the column. The pack_start method is to be used to insert
multiple renderers into the same column, for instance, if you want to insert
an icon and some text into the same cell.
The following works as a replacment for what you are trying to do
col = gtk.TreeViewColumn (hdrs[i])
col.pack_start (r, expand=gtk.FALSE)
col.add_attribute(r, 'text', i)
renderers[i].set_property ('editable', 1)
The attached example is a works.

self.view = view

view.append_column (col)

[pygtk] auto editable gtk.TreeView
Hi,
I'm trying to create an auto editable gtk.TreeView. What I mean with 'auto' is that
you don't have to press the 'Enter' key when you are on a particular cell to make it
editable. Just moving around the cells should make them editable (think in widgets
like the ones used in spreadsheet programs).
There are two steps to make this possible with gtk.TreeView:
1. When the cursor moves you have to make the new cell editable
2. When we go out of a editable cell we need to move the cursor to the next cell. Here
'next' depends on the key the user presses to go out of the editable cell.
I'm currently working on step 1 and I was succesfull with a small demo in C. The funny
thing is that exactly the same code in Python doesn't work. I'll attach both codes and
I'll try to explain what I think is happening:
What I do is connect_after the 'move-cursor' signal of the gtk.TreeView to a callback.
In this callback I retrieve the current cursor and call treeview.set_cursor(path,
column, start_editing=gtk.TRUE), which should make that cell editable if we trust the
API doc. Note: I use the connect_after and not the connect method because the default
signal handler is the one which actually move the cursor and if our callback is called
first we would be working with the old cursor.
The commented line in the Python code is a nasty hack that make it works. It simply
add a timeout that set the cursor, instead of setting the cursor in the 'move-cursor'
callback. You can uncomment it to see what I mean.
I suppose this is a bug in PyGTK (since the C code works) but I'm not sure so I want
some comments before filling a bug report.
By the way, any clue to implement step 2 is greatly welcomed :)

Lorenzo

[pygtk] TreeView column expanding
Hi,
I have built up an app using glade-2 and it loads and runs fine using
gtk.glade. One of my widgets is a TreeView using a ListStore and I'm
having a bit of trouble figuring out how to make all the columns
expand.
Google hasn't turned up a solution and the PyGTK FAQ Entry 13.19
gives a hint as such:
Another thing to note is that renderers use the normal GTK packing
mechanism. If you want one renderer to expand and take up any extra
space (or `compete' for it if more than one cell has expand=TRUE),
pack it with expand=TRUE, and vice-versa.
I not sure how to perform the packing of the column so I can set
expand to TRUE.
Here's what I've got so far:
class ListView:
def __init__ (self, view, model, hdrs, renderers, sel_cb):
self.view = view
view.set_model (model)
view.set_headers_visible (gtk.TRUE)
for i in xrange (len (hdrs)):
# Set text to i+2 to skip over the PYOBJECT in column 0 of
# the model and the BOOLEAN in column 1.
col = gtk.TreeViewColumn (hdrs[i], renderers[i],
text=i+2, editable=1)
renderers[i].set_property ('xalign', 0.50)
renderers[i].set_property ('font-desc', font_fixed)
col.set_resizable (gtk.TRUE)
col.set_alignment (0.50)
# This is obviously wrong.
col.pack_start (renderers[i], expand=gtk.TRUE)
view.append_column (col)
view.show()
sel = view.get_selection ()
sel.set_mode ('single')
sel.connect ('changed', sel_cb)
Elsewhere, I define the following and pass them to the ListView init
method:
types = [ gobject.TYPE_STRING ] * 10
renderers = [ gtk.CellRendererText () ] * 10
hdrs = [ 'Address', 'Name',
'Bit 7', 'Bit 6', 'Bit 5', 'Bit 4',
'Bit 3', 'Bit 2', 'Bit 1', 'Bit 0' ]
And the view is instantiated with this:
def setup_treeview (self, widget_name, types, hdrs, renderers, sel_cb):
model = ListModel (*types)
view = self.wTree.get_widget (widget_name)
view = ListView (view, model.store, hdrs, renderers, sel_cb)
The problem code is:
# This is obviously wrong.
col.pack_start (renderers[i], expand=gtk.TRUE)
which generates quite a few of these:
(gui.py:26663): Gtk-CRITICAL **: file gtktreeviewcolumn.c: line 1234
(gtk_tree_view_column_pack_start): assertion `!
gtk_tree_view_column_get_cell_info (tree_column, cell)' failed
>From reading the docs, I kinda think that my call to col.pack_start()
is not the right approach as it seems to expect a specific cell, not a
renderer instance.
Just in cases it's of interest, here's how I'm adding my data to the
list store model:
def insert_row (self, data):
"""Also adds the python object, 'data' to the store in the first
column. Set the value of the boolean to TRUE so we can edit the
cells later.
"""
iter = self.store.append ()
args = [0, data, 1, gtk.TRUE]
for i in range (len (data)):
args.extend ([i+2, data[i]])
self.store.set (iter, *args)
I'm using the current 2.2.x gtk+ libs.
Any insight into how to do this is appreciated.
Thanks.
Ted Roth

[pygtk] GnomeEntry and events
Hi all, I'm looking for an event that's fired by a GnomeEntry widget when an entry is selected from the history list. Something like 'selection_changed' from GtkCombo->GtkList. I mean I could connect the 'changed' signal to the widget, but then it would be fired each time the user types something into the Entry... I searched for this topic on the net, and the only hit was an archived posting from this list dated to April(?) 2001 with no reply.
