Subject: QClipboard: Fix autotest fails
X-Git-Tag: qt-v5.0.0-alpha1~735
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=63017136a1a6625c3528f9b237468a55b7fab12c;p=profile%2Fivi%2Fqtbase.git

QClipboard: Fix autotest fails

tst_qclipboard.cpp still has Q_WS_WIN which must be clear away. After
clean up, auto test will fail under windows: When setMimeData() is
called, dataChanged() signal will be emited twice.

The solution for QTBUG-24184 has partially solved the problem, but it
still there. Make sure emitChanged() only called by QPlatformClipboard
will give our more control for this.

Task-number: QTBUG-24484
