[Qt-interest] Block all signals of ui class

[Lucas Pereira Caixeta]

 Bool QObject::blockSignals ( bool *block* )

If *block* is true, signals emitted by this object are blocked (i.e.,
emitting a signal will not invoke anything connected to it). If *block* is
false, no such blocking will occur.

The return value is the previous value of
signalsBlocked<http://qobject.html#signalsBlocked>
().

Note that the destroyed <http://qobject.html#destroyed>() signal will be
emitted even if the signals for this object have been blocked.

See also signalsBlocked <http://qobject.html#signalsBlocked>().



Have fun!! [?]
