Like I said, the slot must be a member of a QObject derived class. Also,
sender() should be from the receiver - there's no point in asking the
sender who the sender is :)
So, testDlg should sub-class from QObject and the lostFocus() method
should be...
def lostFocus(self):
print self.sender()

RE: [PyKDE] Static member functions
Followup: I seem to have found sender(), but I get the usual 'you can't
do this because it was not created in python' error.
So I still don't know how to go about it. Here's a sample class that I
just typed up:
class testDlg:
def __init__(self):
self.dlg=QWidgetFactory.create('lineedit.ui') #just a
dialog with 2 lineedit boxes named lineedit1 and lineedit2, clicking
between them should print out different instances
self.dlg.connect(self.dlg.child('lineedit1'),
SIGNAL('lostFocus()'), self.lostFocus)
def lostFocus(self):
print self.dlg.sender() # error here
def show(self):
self.dlg.show()
if __name__=='__main__':
d=testDlg()
d.show()
qApp.exec_loop()

Re: [PyKDE] Static member functions
Hi,
I think I understand your problem as follows: You have a non-parametrized
signal, lostFocus, that you want to connect to one slot - but then somehow
"magically" there shall be a reference to the object the signal came from is
passed.
May be what could help is somthing like this:
class Magic(QObject):
def __init__(self, dialog, key):
QObject.__init__(self)
self.dialog = dialog
self.key = key
def focusLost(self):
self.dialog.keyLostFocus(self.key)
Now you connect your signals in a loop like this:
for key in keys:
self.connect(key, SIGNAL("focusLost()"), Magic(self, key).focusLost)
That assumes that self is the dialog and keys the list of key-widgets.
HTH,
Diez

Re: [PyKDE] Static member functions
I heard Hihn, Jason said: > How can I do this in python? It may be I'm not getting your question, but... What's the problem exactly? You can have global objects (which includes functions) all you want, really. Example: ---[ globalstuff.py ]-- data = None --- ---[ A.py ] import globalstuff def functionA(): globalstuff.data = 42 --- ---[ B.py ] import globalstuff def functionB(): print "The global data contains:", globalstuff.data --- ---[ main.py ]- import globalstuff from A import functionA from B import functionB # Set the global bit of data with functionA() from module A: functionA() # Print the global bit of data with functionB() from module B: functionB() # Set the global bit of data ourselves: globalstuff.data = "Nobody expects the Spanish Inquisition!" # Then print it with functionB() from module B: functionB() print "See, Jason?

RE: [PyKDE] Static member functions
Ok, my problem is that I want to provide some function that is called by
the widget that generates the signal.
I have an On-Screen Keyboard. Each text-control gets assigned a
lostFocus handler. I need that handler to do one thing. I need it to
store that widget's id (or instance) so the OSK knows where to write the
characters to.
The issue I am having is in my previous environment, I could just say
the equivalent of:
Dlg.child('text1').lostFocusEvent=some_func()
#0 params passed
And some_func() would be given the 'this' object by the interpreter
(because it was then a member function of the class). This is not the
case for python. Assigning a global some_func() to an object does not
get the self object, even though it is now in the object's name space.
For connects, I tried:
Dlg.connect(dlg.child('text'), SIGNAL('lostFocus()'), setKeyboardDest)
#0 params passed
Dlg.connect(dlg.child('text'), SIGNAL('lostFocus()'),
self.setKeyboardDest)
# 1 param, self, passed, but this is the dialog instance
Furthermore, the dialogs that receive input are created from
QWidgetFactory, so I don't know if I can subclass the text controls at
runtime.
I am lost, lost, lost. I figure the ultimate way out is to assign each
slot to a separate function, but that is not elegant, since they would
all be of the form:
Def text1_lostfocus(self)
Globals.lastText=self.dlg.child('text1')
... repeat for each text box...
Then connect the signal to each indivisual slot. It is quite a waste
though. Also, adding text boxes would require recoding of the python
script, where the old method would not.

[PyKDE] Static member functions
I need to have a lostfocus event store the object that created the event. In my previous language, I had a global function that could do it, because I could bring it in to the class by setting it at run-time. The ‘this’ object, would then be the object that generated the event. It was then easy enough to say : global lostFicusObj=this Then later, I could use this.whatever() How can I do this in python? I’d really hate to have a function for every possible widget.
