I have a very simple program:
from PyQt4 import QtGui, QtCore
import sys
class Win(QtGui.QWidget):
SaveFiles = QtCore.pyqtSignal()
def __init__(self,parent=None):
QtGui.QWidget.__init__(self,parent)
self.fileDialog = QtGui.QDialog()
self.SaveFiles.connect(self.fileDialog.exec_)
self.SaveFiles.emit()
app = QtGui.QApplication(sys.argv)
win = Win()
win.show()
win.raise_()
sys.exit(app.exec_())
which produces the error:
Traceback (most recent call last):
File "jif.py", line 23, in <module>
win = Win()
File "jif.py", line 18, in __init__
self.SaveFiles.connect(self.fileDialog.exec_)
TypeError: 'exec_()' has no overload that is compatible with 'SaveFiles()'
This is with PyQt 4.7.2. The problem is not apparent in 4.7.
If I subclass QDialog, the problem persists, but I can workaround by
defining my own exec_ method.
Best Wishes,
Stuart McNicholas
