Subject: [PATCH 30/39] kconfig qconf: fix the type of the desktop widget

From: Markus Heidelberg <markus.heidelberg@....de>

QApplication::desktop() returns a pointer to QDesktopWidget, not to
QWidget.

Fixes the following compiler error after a quick conversion with 'qt3to4',
which occured with g++ 3.4.6 and 4.1.2, but not anymore with 4.3.2.

scripts/kconfig/qconf.cc: In constructor 'ConfigMainWindow::ConfigMainWindow()':
scripts/kconfig/qconf.cc:1289: error: cannot convert 'QDesktopWidget*' to 'QWidget*' in initialization
