[Qt-interest] newbe alert - I am trying to convert plotting from C# to QT4

[Doug Stewart]

I am just learning QT4 and want to do a plotting program in qt4 similar to
the one I have running in C#

In C# I have a Panel added to a Form and I do all the drawing on this panel.
In C# when I double click on the Panel it makes a function called
Panel_paint.. etc.

Panel_paint gets called whenever It needs refreshed (from the OS or from an
Invalidate call).
I then put inside Panel_paint all the code to read an array and use the
line_draw function to plot the graph.

Now in qt-creator I am trying to do the same steps
  - I can't fined a Panel
  - I did find graphicView  but am not sure how to use it
   -I also see  slot   and select a signal but nothing for painting!

Could some one help me get to the point where I can plot an array full of
numbers?
Once I get past this hurdle The rest of QT4 looks fairly smooth sailing!
