Created attachment 416728 [details] Test script to show DeprecationWarning Description of problem: I have a code which tries to prevent line wrap by calling dialog.label.set_line_wrap(False) on RHEL 6, and pygtk2 (?) complains about the call being deprecated. Using set_property does not help either. Colleagues at #desktop say that it is not marked as deprecated in C API, so I believe it should not be in python either. Version-Release number of selected component (if applicable): # rpm -q pygtk2 pygtk2-2.16.0-3.el6.i686 How reproducible: Deterministic. Steps to Reproduce: 1. Run the attached script with python. Actual results: /tmp/test_wrap.py:11: DeprecationWarning: use set_markup() instead dialog.label.set_line_wrap(False) /tmp/test_wrap.py:12: DeprecationWarning: use set_markup() instead dialog.label.set_use_markup(True) Expected results: No DeprecationWarnings. Additional info:
I can avoid the set_use_markup by using --- /tmp/test_wrap.py.orig 2010-05-26 11:31:27.581399590 +0200 +++ /tmp/test_wrap.py 2010-05-26 11:31:40.452312105 +0200 @@ -7,9 +7,9 @@ is not reflowed, so every even line is very short because it just has those ends.

The deprecation warning is coming from your accessing "dialog.label", which is supposed to be private. See https://bugzilla.gnome.org/show_bug.cgi?id=309180. GtkMessageDialog is rather restrictive in what it will let you do with the labels. You would probably be better off constructing an equivalent window out of GtkDialog, where you'd have full access to the label. Closing this as NOTABUG since the deprecation is intentional.
Alright. How do I achieve the set_line_wrap equivalent then?
As I said, build your own GtkDialog.
