Public bug reported:
According to the documentation: "If you only plan to have simple (text-only)
tooltips on full rows, you can use this function to have GtkTreeView handle
these automatically for you. column should be set to the column in tree_view's
model containing the tooltip texts, or -1 to disable this feature."
This works fine in most cases, but it fails to show anything in the tooltip if
the text contains & or <, or some other odd characters. It shows warnings like
this:
test.py:62: GtkWarning: Failed to set text from markup due to error parsing
markup: Error on line 1: Entity did not end with a semicolon; most likely you
used an ampersand character without intending to start an entity - escape
ampersand as &
gtk.main()
test.py:62: GtkWarning: Failed to set text from markup due to error parsing
markup: Error on line 1 char 12: '<' is not a valid name
gtk.main()
In the attached example, you can see the tooltip on all text unless it has odd
characters like & or <.
Also, commenting out the line with self.window.set_size_request causes the
desktop effects to crash on 10.04.
