Actually Qt projects can be compiled on: Linux, Windows, Mac, FreeBSD, Solaris, Sharp Zaurus, Symbian, and more platforms will be available soon.
Qt improvements of C++
Qt libraries are addressing to more "limitations" of the C++. One of them is the access from the inside objects to their outside world. For example if a window contains a block of buttons - objects of the QPushButton class - it is easy to refer to the properties of the buttons from the exterior window but is difficult to refer to the methods of the exterior window from the button. If we want the button to be able to command something to the window, well, we are in trouble.
Qt is introducing: Connect - a sort of "power cord" which can be used to connect - of course - the state of the button - which isClicked() with a slot of the main windows where it can "power" a method of the main window. For example, the method quit() which is usually used to close the opened window.
Usefulness
Actually, important Companies and more and more universities - yes, even from Eastern Europe - are using Qt for their projects. The Qt is used by the European Space Agency, by Boeing, by Nokia and more ...Qt users arises every week.
