[Qt-interest] About Plugin Architecture in QT

[hakiim warrick]

Hi, thanks a lot, the point i couldnt get is, doesnt it hurt the backward compatibility of the software?
It comes weird to me that plugins should be built with exactly the same version of Qt that the application is built. Say, we built the main app with Qt 4.5 and released it, what if a 3rd party wants to add a plugin, say a video processing filter, to the app after 1 year? Should he build the plugin with the old 4.5 version? And by the way, do you mean that plugins are executables(in win32 for ex.)? Cant they be added as dlls ?
Best regards.
