Updated gtk2 and atk packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The gtk2 packages provide a multi-platform toolkit for creating graphical user interfaces, GIMP Toolkit (GTK+). GTK+ offers a complete set of widgets and is suitable for small projects as well as complete application suites.
The ATK library provides a set of interfaces for adding accessibility support to applications and graphical user interface toolkits. By supporting the ATK interfaces, an application or toolkit can be used with tools such as screen readers, magnifiers, and alternative input devices.
The gtk2 packages have been upgraded to upstream version 2.20.1, which provides a number of bug fixes and enhancements over the previous version. (BZ#883022
The atk packages have been upgraded to upstream version 1.30.0, which provides a number of bug fixes and enhancements over the previous version. (BZ#883027
When rendering the text in a combo box, the GTK+ cell renderer always rendered text that was rendered last time as the first item. Consequently, if the previously rendered text did not match any item in the name set, the first item in the "Categories" combo box in the Contacts view could have been rendered as empty, which affected accessibility and automated tests. This update ensures that the cell renderer is now properly updated and renders items for the current combo box call so the aforementioned problem no longer occurs.
Due to a bug in the GtkTreeView interface, the expand arrows in a tree view in Evolution stopped functioning after clicking on an icon in the system tray. This update increases robustness of the tree expanding and collapsing code, which fixes this bug.
Users of gtk2 and atk are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
