[pygtk] TreeView/CellRenderText and numbers

[Olaf Devik]

I am struggling with TreeView and CellRendererText.

I have a ListStore containing a number of fields with strings and
integers. The ListStore is connected to a TreeView and the string fields
render well as expected, but the fields with integers will not render.

How can I render integer values in the TreeView?

Probably a simple question with a simple answer, but I have so far not
found any simple solution. Most problems listed in the FAQs are far to
advanced compared to my simple problem.

Tips are welcome

Regards

Olaf Devik

Please put your code.
You should define the right type in ListStore (int/str), and if the int feild is editable, I think you have to handle "edited" signal manually to validate input text.

Exactly like you would render a string value from your model. For
example, assuming field 1 in your model is of type int:

cell = gtk.CellRendererText()
intcolumn = gtk.TreeViewColumn('Amount')
intcolumn.pack_start(cell, True)
intcolumn.add_attribute(cell, 'text', 1)

A complete and working example is attached.

Thanks to both replies. Info from Dieter did the trick, the critical
line was intcolumn.add_attribute(cell,'text',1).

I tried to set same trough use of
gtk.TreeView.insert_column_with_attributes, which was ok for the columns
with string, but failed when an integer was required. When that failed,
my confusion went to a high level.

So basically, I am now one step closer to master the mysteries of
TreeView and ListStore.

Ah yes, insert_column_with_attributes also works (and even
saves a bit of typing). See attachment :)
