Fix empty window title regression, add application display name to window title
This increases consistency a lot: all windows and dialogs from a Qt application will show the app display name in the caption, on Windows and X11. This helps identifying which app a dialog belongs to, which is especially useful when the dialog is very generic and shows up unexpectedly. For compatibility reasons, the app name is added to the caption only if setApplicationDisplayName() was called -- or if the caption would be completely empty. The standard Qt4 case (setWindowTitle + no display name) is unchanged. Change-Id: Ib284c62c1f4c0bc923e5bc2d10247d95e9aa76c1 Reviewed-by: Samuel Rødal <>

This property only makes sense for windows. It associates a file path with
a window. If you set the file path, but have not set the window title, Qt
- sets the window title to contain a string created using the following
- components.
- On Mac OS X:
- \list
- \li The file name of the specified path, obtained using QFileInfo::fileName().
- \endlist
- On Windows and X11:
- \list
- \li The file name of the specified path, obtained using QFileInfo::fileName().
- \li An optional \c{*} character, if the \l windowModified property is set.
- \li The \c{0x2014} unicode character, padded either side by spaces.
- \li The application name, obtained from the application's
- \l{QCoreApplication::}{applicationName} property.
- \endlist

If the window title is set at any point, then the window title takes precedence and
will be shown instead of the file path string.
