Question

Coming from the .NET world over to Python and PyQt4. Was wondering if anyone is familiar with any functionality that would allow me to bind data to Qt widgets? For example (using sqlalchemy for data):

gems = session.query(Gem).all() list = QListWidget() list.datasource = gems 

Is such a thing possible?

Answer 1

One option would have a function that returns a list (or tuple) object from a query, and then use that to update the QListWidget. Remember that the QListWidget stores QListStrings. Your update function might look like this:

def updateQListWidget(qlistwidget, values):         ''' Updates a QListWidget object with a list of values         ARGS:             qlistwidget  - QListWidget object             values       - list of values to add to list widget         '''         qlistwidget.clear()         qlist = QtCore.QStringList()         for v in values:             s = QtCore.QString(v)             qlist.append(s)         qlistwidget.addItems(qlist)
