[pygtk] TreeView
Possibly silly question: I have created an interface with gtk.ListStore and gtk.TreeView into which users drop data. The data should be copied into the cells. All of this works quite well, except that the x,y coordinates sent to the callback seem to point to the following row, rather than the current row. I can compensate with this with simple row arithmetic (what I have done as a stop-gap solution) but this obviously presents a problem when one gets to the first or last row in a table. I could also heuristically tweak the value of y, but this seems almost as inelegant. I suspect that there is a simple way of changing this behavior for the whole table (TreeView.set_drag_dest_row()?) (that is, changing it so the x, y coords returned reflect the row the mouse cursor is hovering over) but I haven't figured out how to do it. Any hints? -- David Mortensen STEDT/Department of Linguistics 1203 Dwinelle Hall; University of California at Berkeley Berkeley, CA 94720-2650 OFFICE: (510)643-9910 CELL: (510)427-2952 AIM: vamchoj ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

A callback for a signal needs to have a certain signature. This means
that the callback for "clicked" specifies a certain number of arguments,
and that number of arguments may not be (and is not) the same as the
number of arguments for GtkWindow.destroy().
In this case, the only approach is to use a proxy function as a callback
and have that function call destroy(). That's not necessarily a bad
thing, though; you'll realize sooner or later that destroy() alone
wasn't what you wanted to call, and that you need to do that "one extra
thing" when closing that window.
The lambda solution is a simplified way of providing that proxy, but I
swear by defining explicit callback functions, even if all they do is
call a gtk method.
Take care,

Really sorry, i pressed the wrong button :)
Here's the code :
button = gtk.Button("Cancel", gtk.STOCK_CANCEL)
button.connect("clicked", exit_window.destroy)
exit_window.action_area.pack_start(button, gtk.FALSE, gtk.FALSE,
0)
button.show()
I've searched on google and found a mail sent to this mailing list :
"Manish Jethani manish.jethani at oracle.com
Fri May 9 07:26:56 WST 2003
To fix this, I changed it to:
self.button.connect("clicked",
lambda x: self.window.destroy())
connect_object has been replaced with connect. This works fine
i.e. calls destroy() successfully. Does this look ok?"
Is there another way ? I mean, something more clean ?
Thanks.

but set_font_name just does not set anything and return false. I am not sure if it is
a pygtk or gtk bug.
Any idea would be appreciated to fix it:
