I've trying to understand how to make a cmd button call a method when the
button is pressed.
I havne't been seen an example in the Signals & Slots section of the QT docs
which describe how to connect a widget signal to a callback function, only
how to call a widget slot function.
I don't get any runtime errors in my attempt to do this, but the callback
function isn't being called.
What is the preferred method of registering a non-widget slot to be called
by a widget signal?
class Dialog(QtGui.QDialog):
def __init__(self, parent=None):
QtGui.QDialog.__init__(self, parent)
self.patchBrowser = QtGui.QTextEdit()
# layout code omitted for brevity
def updateTextBox(self): # this function shoul dbe called, when the
button is pressed
self.patchBrowser.setPlainText(self.tr("Callback was called"))
def createPatchnameComboBox(self):
self.patchNames = QtGui.QComboBox()
self.patchNames.addItem("Entry 1")
self.patchNames.addItem("Entry 2")
# layout code omitted for brevity
#self.connect(self.patchNames, QtCore.SIGNAL("higlighted"), self,
QtCore.SLOT("updateTextBox") ) # doesn't call updateTextBox
self.connect(self.patchNames, QtCore.SIGNAL("activated"), self,
QtCore.SLOT("updateTextBox") )
