Capture all button clicked from a widget

[Lesiok]

For every created button do :

QPushButton *b1 = new QPushButton( "A", this );
connect( b1, SIGNAL(clicked()), sm, SLOT(map()) );
connect( b1,SIGNAL(released()),&m_timer ,SLOT(start()));

QPushButton *b1 = new QPushButton( "A", this );
connect( b1, SIGNAL(clicked()), sm, SLOT(map()) );
connect( b1,SIGNAL(released()),&m_timer ,SLOT(start()));

To copy to clipboard, switch view to plain text mode 

where m_timer is a QTimer hiding the keyboard after 50 seconds.
