[Qt-interest] draw a pixmap with a table

[Stefanos Antaris]

Hello.I am going to receive a 2 dimension table which is going to have 
unsigned char on each cell.Every cell is going to show me the brightness 
of the pixels.Now i found that QPixmap can do that but i can't manage 
it.Can anyone help me how could i draw a widget with that table?With 
QPixmap or something else?Thanks.
