Package: libgtk2.0-0
Version: 2.12.9-2
Severity: normal
Hi,
Under some circumstances, GtkTreeView fails to properly resize columns which
have their expand property set to TRUE.
In the attached testcase (using pygtk), the middle column has its expand
property set to TRUE and is allowed to ellipsize text. Click on the zoom
button, and see how the column is not resized as it should be. Resize the
window using the bottom-right handle and see how it magically gets resized
as it should.
Stumbled upon this bug while using a GtkTreeView this week in an application;
discussed the problem with Josselin who asked for a testcase for this
particular situation, as it's unclear whether the current patch lacks this
particular case or is broken for this particular case.
Thanks,
JB.
