PyQt signals/slots dialogs question

[AlienBaby]

Hi,

I'm just starting to get to grips with PyQt, and I'm having a bit of
trouble connecting slots / signals, or understanding how I should do
so to achieve what I am after.

I am trying to write an application that will display a sequence of
dialogs, with back / next / cancel buttons to step through the
dialogs. Each dialog will capture user input, ask the user to browse
for a file, present some radio-buttons for a selection etc..

I've put the dialogs together in Designer, and I come to startup the
app with a small piece of python code, create an instance of each
dialog, and then connect up the buttons to any methods needed to
control the movement through the dialogs etc.

I'm having a brain-freeze though, and just can't figure out what I
should be doing next, or the best approach to take.

for example, Currently I am thinking I would need to connect the
clicked() signal of the Next button on dialog 1 to a method say,
'dialog1Next' that would then hide dialog1 and show dialog2.  I would
then need to connect Dialog 2's clicked() signal of its next button to
a method called 'dialog2Next' that hides dialog2 and shows dialog3
etc...

I would also, for example,  need methods for dialog2Back,
dialog2cancel, dialog1cancel etc..

I'm having trouble figuring out how to setup the connections, and
where the slot-methods should live..

I have this so far;

from PyQt4 import QtCore, QtGui
from WELCOME import Ui_Dialog as welcomeDialog
from SOURCE_TYPE_SELECT import Ui_Dialog as sourceTypeSelectDialog
from SOURCE_TYPE_CONFIRMATION import Ui_Dialog as
sourceTypeConfirmationDialog
from ACCEPT_EULA import Ui_Dialog as acceptEulaDialog
from CONFIRM_REQUIREMENTS import Ui_Dialog as
confirmRequirementsDialog
from SOURCE_BINARY_LOCATE import Ui_Dialog as sourceBinaryLocateDialog
from SOURCE_BINARY_PROBLEMS import Ui_Dialog as
sourceBinaryProblemsDialog
from OUTFILE_LOCATE import Ui_Dialog as outfileLocateDialog
from OUTFILE_PROBLEMS import Ui_Dialog as outfileProblemsDialog
from COLLECTION_PROGRESS import Ui_Dialog as collectionProgressDialog
from OUTFILE_LOCATION import Ui_Dialog as outfileLocationDialog



class StartQT4(QtGui.QDialog):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.Welcome = welcomeDialog()
        self.Welcome.setupUi(self)
        self.SourceTypeSelect = sourceTypeSelectDialog()
        self.SourceTypeConfirmation = sourceTypeConfirmationDialog()
        self.AcceptEula = acceptEulaDialog()
        self.ConfirmRequirements=confirmRequirementsDialog()
        self.SourceBinaryLocate=sourceBinaryLocateDialog()
        self.SourceBinaryProblems=sourceBinaryProblemsDialog()
        self.OutfileLocate=outfileLocateDialog()
        self.OutfileProbelms=outfileProblemsDialog()
        self.CollectionProgress=collectionProgressDialog()
        self.OutfileLocation=outfileLocationDialog

        #Connect up next/back/cancel etc.. buttons

???     self.Welcome.connect(self.Welcome.welcomeNext,
QtCore.SIGNAL("clicked()"),WelcomeNext)



def WelcomeNext():
        #Code here to hide Welcome dialog and show SourceTypeSelect
dialog



if __name__ == "__main__":
	app = QtGui.QApplication(sys.argv)
	myapp = StartQT4()
	myapp.show()
	sys.exit(app.exec_())





My questions are, am I approaching this the right way, with a method
per action per dialog to move through the dialogs, and just how do I
setup the connections I need. I'm getting confused with scope etc. IE:
if the connect is right, and WelcomeNext fires, how can it refer to
myapp.SourceTypeSelect.show() or myapp.Welcome.hide()


Any help much appreciated.
