Review request for KDE Frameworks, KDE Usability and Christoph Feck.


Repository: kwidgetsaddons


Description
-------

If we enable word-wrap on a vanilla KMessageWidget (with no additional tool buttons added), the close button is placed on row number 1 (in the grid layout), resulting in wasted space (see first messagewidget in the screenshots).

This patch places the close button on row number 1 only when we actually have other buttons in the messagewidget. This way we save space in the normal case.
