Hi,
I have the following error when running my C++ code from python.
The C++ code is a multiple inheritance class. It is a worker thread
which has to emit events.
Why doesn't this work ?
File "test.py", line 165, in __init__
self.didSomething.connect(self.handletrigger)
TypeError: pyqtSignal must be bound to a QObject, not 'ImageWriter'
C++ header file:
class QtWorker: public QObject, public Worker {
public:
QtWorker(const std::string& name=""): Worker(name),
p_widget(0) {}
virtual ~QtWorker() {}
QWidget* GetWidget() {return p_widget;}
protected:
QWidget* p_widget;
};
SIP Code:
namespace core
{
class QtWorker: QObject, core::Worker
{
%TypeHeaderCode
#include "core/Qtworker.h"
%End
public:
QtWorker(const string& name);
void *GetWidget();
};
};
Python Code:
class ImageWriter(core.QtWorker):
didSomething = pyqtSignal()
def __init__(self):
super(ImageWriter,self).__init__()
self.didSomething.connect(self.handletrigger)
def Process(self):
self.didSomething.emit()
return True
def handletrigger(self):
print "ImageWriter signal received"
