Dropping Visual Studio 2008 as official tier 1 platform and replacing it with Visual Studio 2010 has the side effect that the current minimum supported Qt version 4.6.2 does not officially support VS2010.
I would suggest to move to Qt 4.7 as a minimum required. It officially introduced VS 2010 support and there are still offical VS2008 binaries available.

Update Qt minimum version to 4.7.
With Qt 4.7 we can remove QmitkLineEdit which is a wrapper for QLineEdit that allows to set a placeholder text. In Qt 4.7, QLineEdit has a method called setPlaceholderText(). QmitkLineEdit is only used in the Properties view.
Thanks for the hint. Since QmitkLineEdit is public API, I will deprecate it and we can remove it after the release.

Use QLineEdit from Qt 4.7 directly.
