convert my mainwindow in one .dll with qt

[SirJonas]

Hi it's possible to convert my mainwindow in one dll dynamic link library? And my other question is if i did one static link library i can include in one dynamic link library to include all features of this and then use like a dynamic link library calling the functions and all things with my dynamic link library. And the last question is what will be the problem if i want to use this .dll with one program that it is not for qt. thanks!

The dll is done with qt.

I have no idea what you mean by this. Convert mainwindow to what?

This probably will not work unless you implement a QApplication instance inside your DLL so there is an event loop for the Qt QObject-based class instances to use.

in other words libraries of qt are not prepared for being used by other class of program's. They will work only with qt program's but if i want to get to work with other program's, i must to implement a QApplication instance inside my DLL. So i think it's a little difficult to implement with qt so maybe i must to use pure c++.
