QApplication::restoreOverrideCursor() can not restore cursor
Message 1 in thread
Hi Sir,
Under QT 4.3.0Beta, QApplication::restoreOverrideCursor() can not
restore the cursor set by
QApplication::setOverrideCursor( QCursor(Qt::WaitCursor) )
It is easy to reproduce by running the following example under
different version(ex. Qt 4.2.3 and Qt 4.3.0Beta).
===============================================
#include <QApplication>
#include <QLabel>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QApplication::setOverrideCursor( QCursor(Qt::WaitCursor) );
(new QLabel(QT_VERSION_STR))->show();
QApplication::restoreOverrideCursor();
return app.exec();
}
===============================================
Cursor was restored under Qt 4.2.3, but not under Qt 4.3.0Beta.
Confirm please.
Regards,

You are right, seems the cursor can not be restored from the widget(s)
created between
QApplication::setOverrideCursor( QCursor(Qt::WaitCursor) )
and
QApplication::restoreOverrideCursor()

Confirmed and fixed ;) Tomorrow's snapshot will work as expected.
