[PyQt] (no subject)

[Wes Goodenough]

Hello. I'm learning PyQt for use with Designer for database applications.  
I've been reading all the resources and tutorials, and I have a good amount  
of 
experience with GUI and Database programming in MS ACCESS. I have finally 
decided to put in the effort to lear python and QT but i'm stuck and 
need help seeing what I'm doing wrong. 

I have Ui_Clients.py generated by Eric from "clients.ui" created by  
Designer.

class Ui_MainWindowClients(object):
    def setupUi(self, MainWindowClients):
        MainWindowClients.setObjectName(_fromUtf8("MainWindowClients"))
        MainWindowClients.resize(640, 480)

... etc
Among the widgets is QtGui.QTreeView "ClientTreeView" as follows:

        self.ClientTreeView = QtGui.QTreeView(self.centralwidget)
        self.ClientTreeView.setGeometry(QtCore.QRect(30, 290, 401, 111))

... etc ending with

        self.ClientTreeView.setObjectName(_fromUtf8("ClientTreeView"))

I also have Clients.py as generated by Eric from "clients.ui"

class MainWindowClients(QMainWindow, Ui_MainWindowClients):
    SSN, FNAME,  LNAME,  SEX,  RACE,  DOB = range(6)
    ASC = 0
    DESC = 1
    
    def __init__(self, parent = None):
        QMainWindow.__init__(self, parent)
        self.setupUi(self)
        
        dbType = "QMYSQL"
        dbConnect = "clientsdb"
        dbName = "clients"
        dbTable = "Clients"
        dbUname = "root"    #because db has been created with user name
        dbPW = ""                  #because db password is not set
        db = QSqlDatabase.addDatabase(dbType, dbConnect)
        db.setDatabaseName(dbName)
        db.setUserName(dbUname)

        if not db.open():
            QMessageBox.warning(None,  "ClientTracking:".join(dbName),  
                                QString("Database Open Error:  
%1").arg(db.lastError().text()))
            sys.exit(1)
            
        self.clientModel = QSqlTableModel(None, db)
        self.clientModel.setTable("Clients")
        self.clientModel.setSort(SSN, ASC)
        self.clientModel.select()
        
        self.ClientTreeView = QTreeView(self)
        self.ClientTreeView.setModel(self.clientModel)
        self.ClientTreeView.setGeometry(QtCore.QRect(30, 290, 401, 111))
        self.ClientTreeView.show()
        
    @pyqtSignature("QString")
    def on_cmbBoxUniqueID_editTextChanged(self, p0):
        # TODO: not implemented yet
... etc    

My problem is in connecting self.clientModel to self.ClientTreeView.
When i run this code MainWindowClients is painted including ClientTreeView 
from Designer (blank), but instead of having the model attached to  
Designer's 
widget ClientTreeView, a second QTreeview widget is created at default  
Geometry.


On a related item, also note... the code snippet in the PyQt documentation 
explaining how to use QT Designer with PyQt contains the following for  
multiple 
inheritance instancing: 
The reference to "self.ui.okButton.clicked.connect(self.accept)" is  
confusing.
It makes sense for the simple sub-classing of QDialog presented just before,  
but
it does not help trying to figure out what my problem is...

from PyQt4.QtGui import QDialog
from ui_imagedialog import Ui_ImageDialog

class ImageDialog(QDialog, Ui_ImageDialog):
    def __init__(self):
        QDialog.__init__(self)

        # Set up the user interface from Designer.
        self.setupUi(self)

        # Make some local modifications.
        self.colorDepthCombo.addItem("2 colors (1 bit per pixel)")

        # Connect up the buttons.
        self.ui.okButton.clicked.connect(self.accept)
        self.ui.cancelButton.clicked.connect(self.reject)

Any help will be appreciated... Thanks. I'm looking forward to using the  
power
of PyQt with MySql etc for non-MS bound projects.

Wes
