Hello All,

I am a beginner when it comes to Qt/C++ coding and an absolute beginner when it comes to coding graphics...
I am developing an application involving liquid levels in a tank, I would like to have a graphic that shows the liquid level of two different liquids in the tank based on the user input.
I am thinking I will need an image for my tank that I draw a line on for the liquid level and then fill the tank with a colour up to the line.
Is this the right approach?
What class[s] should I look into to accomplish this if this is the right approach?
This may be way more complicated then a rookie should be tackling?
Thanks for any input!
Cheers,
Jon
