Some code snippets should make things clearer.
(Colon's show where some lines of code have been skipped.)

ui.py has

from calibre_plugins.ag_normepub.main import PlugMain
:
    self.qaction.triggered.connect(self.show_dialog)
:
    def show_dialog(self):
:
        ufig = self.interface_action_base_plugin.do_user_config
        plug = PlugMain(self.gui, self.qaction.icon(), ufig)
        plug.show()

main.py has:

class PlugMain(QDialog):

    def __init__(self, gui, icon, ufig):

        self.gui = gui
        self.ufig = ufig
        QDialog.__init__(self, gui)
:
        self.btn_norm = QPushButton('Normalise ePub', self)
        self.btn_norm.clicked.connect(self.normalise)
        self.lay.addWidget(self.btn_norm)
:
    def normalise(self):
:

and normalise does all the work. So I want get rid of this QDialog but I can't delete the whole class as normalise() is defined within it.
