Bug#370557: libgtk2.0-0: Editable cells in TreeStore are not correctly aligned

[markus koller]

Package: libgtk2.0-0
Version: 2.8.18-1
Severity: minor

Hi

It seems the libgtk2.0-0 update from 2.8.17 to 2.8.18 introduced a minor
cosmetic bug where the text entry for editable cells in a TreeView isn't
correctly aligned, i.e. it's about 10 pixels too far to the right.
This only happens when you press enter on the selected cell, if you click
on it, the entry is correctly aligned.

I've attached two samples, one for PyGTK and one for Ruby-GTK2, which both
exhibit the bug. I can confirm that they both behave correctly if I
downgrade to 2.8.17 again.


Cheers,
Markus
