Hey people,
I have a simple question about using QListView in my application.
Lets say, I want QListView to display a number of strings.
On the command line the following works:
str_list = ['str1', 'str2', ... , 'strn']
qstr = QStringList(str_list)
qstr_model = QStringListModel(qstr)
lv = QListView()
lv.setModel(qstr_model)
lv.show()
I get a ListView with the strings in there. Great.
Now I got the following code in my app and it doesn't show anything:
class ListViewTest(QtGui.QMainWindow):
def __init__(self, *args):
apply(QtGui.QMainWindow.__init__, (self, ) + args)
self.setGeometry(300, 300, 300, 50)
self.setWindowTitle('ListViewTest')
qstr = QtCore.QStringList(QtCore.QString('foo'))
qstr_model = QtGui.QStringListModel(qstr)
self.lv = QtGui.QListView(self)
self.lv.move(120,10)
self.lv.setModel(qstr_model)
self.pb = QtGui.QPushButton('Update', self)
self.pb.move(10,10)
QtCore.QObject.connect(self.pb, QtCore.SIGNAL('clicked()'),
self.update_list)
def update_list(self):
qstr = QtCore.QStringList(QtCore.QString('bar'))
qstr_model = QtGui.QStringListModel(qstr)
self.lv.setModel(qstr_model)
print 'Button pressed'
app = QtGui.QApplication(sys.argv)
mywin = ListViewTest()
mywin.show()
app.exec_()
Any ideas about that? I surely am confused.
Cheers, Ralph
