Create a QT clock

1. Use of qlcdnumber

# Ifndef mainwindow_h
# Define mainwindow_h

# Include <qmainwindow>

# Include <qtime>
# Include <qtimer>
# Include <qmessagebox>
# Include <qtgui/qlcdnumber>

Public:

Private slots: // keyword
Void Showtime ();

PRIVATE:
Ui: logo * UI;
Qtimer * timer;
};

# Endif // mainwindow_h

# Include "logo. H"
# Include "ui_main1_1_h"

Qtimer * timer = new qtimer (this );
Connect (timer, signal (timeout (), this, slot (Showtime ()));
Timer-> Start (1000 );
Showtime ();
Setwindowtitle (TR ("Digital Clock "));

}

Logo ::~ Logo ()
{
Delete UI;
}

Void logo: Showtime ()

}

2. Image Display

Qstring login: geticonname (qchar X)
