Hi list
You can't if you're in the constructor.
What you have to do, is have your constructor post an event to show or exit. I
use a singleshot timer with a time of 0. This will post the event immediately
after the constructor is done.

Thanks.

Qt can pass its fundamental types across threads - and use them in
signals/slots.
You can only access/manipulate GUI elements in the main thread. Use a
signal/slot between the two threads and have the slot in the main thread update
the GUI. Your line for the *** line should be an emit.
It is relatively easy. You need a QWidget-detived widget that will collect
mouse up/down events and store pixel data. Color is set by setting a pen via a
toolbar. After that you can incorporate zoom/scaling and additional tools.
