      Sorry, but what are you talking about? Which tutorial are you following? What is the rectangle you mention (part of an application? A design done in Qt Creator? Or maybe something else...)? What OS are you on? Which version of Qt Creator and Qt libraries are you using?

          Thank you. This is indeed weird. However, I am not using tutorials myself, so can't really help. Let's hope someone else spots this topic.

              There are lots and lots of tutorials, in the documentation, here on DevNet, etc.

              What I meant to say is that with 7 years of Qt coding past me, I feel little need to follow the tutorials for beginners.

              Maybe you should try a different solution: "the QmlBook":http://qmlbook.org/ It should make your start easier.

                its long time ago but i was busy reading avr

                the tutorial you gave me is great but i have a question:

                is Qt a whole language or just a library/tool for making GUI in C++ :? :\

                  The latter. Qt is C++. It "expands" the language by various interesting concepts (signals and slots, meta object system, etc.) but it is still a C++ framework.

                  Since several years there is additional level available, too: QML (which is indeed a different language), but it in no way stops Qt from being a set of C++ libraries and tools.
