If you put a float in a treeview, you get a really long decimal, which
is almost always not desired. So, after playing around with it for a
while, I came up with this code to truncate floats at 1 decimal place:
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())))
The problem with this is that it uses
GtkTreeViewColumn::get_sort_column_id() to get the column number,
which only works if the column is sortable. Can anyone tell me what
to do if I want the formatting to work on any column, not just
sortable columns? Thank you.
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..
Regards Neil.
