Creating hierarchy of custom widgets



  • I'm trying to create a base class for a widget, then create 2 or 3 subclassed widgets descending from the base class. I'm using Creator's built-in wizard for creating a plugin project for both the base class and the subclass. I can easily build both, but the subclass doesn't appear in Designer, just the base class. When I go to Tools->Form Editor->About Qt Designer Plugins I see this error:

    Cannot load library /usr/share/qt4/plugins/designer/librdftempprobemonitorplugin.so: (/usr/share/qt4/plugins/designer/librdftempprobemonitorplugin.so: undefined symbol: _ZTI16RDFTempProbeBase)

    RDFTempProbeBase is my base class, and RDFTempProbeMonitor is my subclass descended from RDFTempProbeBase.

    I've done a fair amount of research but have been unable to figure out how to resolve this. Any ideas?

    Thanks,
    Rich



  • It figures...I finally ask for help and then figure it out an hour later. If I add the header and source files for the base class to the subclass project, then the subclass shows up in designer.
