What's the better way to construct an application with two or more windows?

njrizzo

I tried with QT Creator but I'm not has be successful.
I'm a newbie on QT structure.
I need some pointers (links) or tutorials.
The application is too simple but I need one windows with commands buttons and
other to show a picture (jpeg, png or other open format) and I can to click on it to get the RGB value.

I don't want the full application, but an exemple showing how I create two or more windows and integrate all and the best object to show the image on the screen ( Qpainter or QLabel or other)
TIA,

Rizzo

Hi and welcome to devnet,

You should take a look at Qt's documentation examples and demos, they show pretty much all the basics you need.
