Problems using DLL

[Chicken Blood Machine]

Thanks for the answer, but the header file is moc'ed. It's in the Generated MOC files in the Visual Studio solution explorer tree.

In Designer, ensure that the export macro is added to your generated base class, by putting it in the 'macros' section of the object viewer tree (I can't remember right now, but it's either called 'macros' or 'defines')

Maybe you can just add the DLL_EXPORT macro to the base class?

He can, but then it will disappear whenever he changes his ui.

Oh, you're right, haha.

I can't find the object viewer tree, is this part of the object inspector?

Yes, sorry Object Inspector. I don't have a copy of Qt3 Designer to hand.

[gfunk]

Where is the macros or defines section in Object Inspector? Or is this just in Qt3? And if yes, is there a Qt4 equivalent? (I'm using Qt4, Windows version, myself)

Thanks,

Thre's nothing in Qt4 (and you don't need it). There is no generated baseclass as such in Qt4*

* You can subclass the ui class in Qt4, but none of the symbols need to be eported.

Thanks for all the answers. There is a export macro property in Qt3 Designer. It's a sub property of the name property. Well hidden!
