Re: [pygtk] Formatting floats in treeview

I use a text renderer with a right justify setting. And convert the
float to a string for the model. That way I can have any number of
decimal points I feel like.
right = gtk.CellRendererText()
right.set_property('xalign',1.0)
column = gtk.TreeViewColumn('number',right)
view.append_column(column)
Hope this helps..

Re: [pygtk] Formatting floats in treeview
Is that code snippet of any help?
def set_foreign_key(self, colnum, SQLObject, colname_1, colname_n):
"""maps a foreign key to a corresponding attribute in the n-table.
colnum is the position of
the column in the treeview (integer), SQLObject is the SQLObject class
the mapped value is
retrieved from, colname_1 is the column name of the foreign key field,
colname_n is the column
the value is retrieved from."""
column = self.get_column(colnum)
cells = column.get_cell_renderers()
cell = cells[0]
column.set_cell_data_func(cell, self.__use_foreign_key_val,
[SQLObject,colname_1,colname_n])
the only problem with this approach is that one col can have various
CellRenderers; this code asserts that only one renderer is assigned to the
cell.

[pygtk] Formatting floats in treeview
If you put a float in a treeview, you get a really long decimal, which

column.set_cell_data_func(renderer,
lambda column, cell, model, iter:
cell.set_property('text', '%.1f' % model.get_value(iter,
column.get_sort_column_id(

GtkTreeViewColumn::get_sort_column_id() to get the column number,
which only works if the column is sortable. Can anyone tell me what
