Mixing Qt3 and Qt4 core in an application
We have a key library used by many of our applications in which no Qt is currently be used for its implementation. The applications which use this library are written with both Qt3 and Qt4. We are interested in using Qt4 core in this library for new functionality we are developing but don't want to break our Qt3 applications. The Qt4 use will be isolated from the library interface and thus there will be no direct interaction between the Qt3 code and the Qt4 core code. Are there known issues that we will run into mixing Qt3 and Qt4 core in this manner? Any pointers to potential issues that we could investigate?
