QLibrary in PyQt

Hi there,

The PyQt docs for QLibrary include the following common-usage snippet:

Code:

---

QLibrary myLib("mylib");
 typedef void (*MyPrototype)();
 MyPrototype myFunction = (MyPrototype) myLib.resolve("mysymbol");
 if (myFunction)
     myFunction();

---

That is not terribly useful, as is, within Python. What I'm wondering is what the Python equivalent would be? This is what I've tried:

Code:

---

def getKeyboardHooks(self):
		kcLib = QLibrary('path\to\my.dll')
		f = kcLib.resolve('installhook')
		if not f:
			print 'DEBUG: no resolve() installhook', kcLib.errorString()
		else:
			print 'DEBUG:', f
			try:
				f(self.winId())
			except Exception as (errstr):
				logger.exception(errstr)

---

On STDOUT I get the else print statement, and the log file gets the following exception: "TypeError: 'sip.voidptr' object is not callable". It seems I need the Python equivalent of a typedef cast but I have no idea how to do this. Web searches on Python typedef and sip.voidptr have yielded very little information, although there is a sip.cast(obj, type) method that looks promising? I don't know. Thanks in advance to any PyQt coders who respond.
