[PyQt] Using a QCompleter with a QLineEdit

[Greg Smith]

Hey Everyone, 

 

I'm trying to get a LineEdit I have in a tool I am writing to have the
ability to auto complete the user's entry based on what they have typed.
>From the sounds of it, QCompleter is exactly what I am after and they
work on QLineEdit widgets. However I am having difficulty getting it to
work, so I was wondering if I could share what I am trying to do and see
if I am doing anything wrong or not doing something that I should be in
order to get it to work.

 

So here's an abridged example of what I am doing.

------------------------------------------------------------------------
--------------------------------------------

>From PyQt4 import QtCore, QtGui, uic

 

defaultList = ['foo', 'bar', 'alpha', 'beta', 'ceti', 'delta']

completerList = QtCore.QStringList()

 

for i in defaultList:

    completerList.append(QtCore.QString(i))

 

#defining my QDialog

class MyPyQtTool(QtGui.QDialog):

    def __init__(self):

        QtGui.QDialog.__init__(self)

        self.ui = uic.loadUi ('C:\\myUiFile.ui')

        lineEditCompleter = QtGui.QCompleter(completerList)

 
lineEditCompleter.setCompletionMode(QtGui.QCompleter.InlineCompletion)

        lineEditCompleter.setCaseSensitivity(QtCore.Qt.CaseInsensitive)

        self.ui.myLineEdit_widget.setCompleter(lineEditCompleter)

        #... defining other tool logic

 

    # I also have the list being modified in another method based off of
user's selection.

    def onMyComboBoxActivated(self)

        # code here where a string list is created from a mysql db query
based on combo box selection.

        for i in dbQryList:

            completerList.append(QtCore.QString(i))

            lineEditCompleter = QtGui.QCompleter(completerList)

 
lineEditCompleter.setCompletionMode(QtGui.QCompleter.InlineCompletion)

 
lineEditCompleter.setCaseSensitivity(QtCore.Qt.CaseInsensitive)

            self.ui.myLineEdit_widget.setCompleter(lineEditCompleter)

 

app = QtGui.QApplication(sys.argv)

dialog = MyPyQtTool()

dialog.ui.show()

app.exec_()

------------------------------------------------------------------------
-----------------------------------------------

This may not be the cleanest way of doing what I want but from the
example shown in the class reference web page, this should be sound.

However when I try to test it, I get no completion what so ever. No
errors are thrown so I am not exactly sure what I am doing wrong.

Is there another method that needs to be executed before it should work?


 

Any help would be truly appreciated!

 

Thanks, 

Greg
