Hi guys,
unfortunately I am pretty new to Python and Qt and all that. Well, I managed to successfully program a little stuff for my work (computational neuroscientist... no comment please), using a simple graphical interface and binding it to my long existing C library. There was no problem, everything was running fine...
... until I decided to upgrade everything to kubuntu's Edgy and PyQt4. Well, I understood that I need to port my original PyQt3 stuff, as there are many principle changes in PyQt4. Anyway, I created my interfaces with Qt4 builder from Trolltech, and connected the buttons in my main Python program (that's the normal way to do, I guess?) However, this most basic "connect" does not work anymore, and I am to new to all that to understand why. Here is an example code which explains the problem:
First, the python code for the ui, generated with pyuic4:
-
import sys
-
from PyQt4 import QtCore, QtGui
-
-
class Ui_Dialog(object):
-
def setupUi(self, Dialog):
-
Dialog.setObjectName("Dialog")
-
Dialog.resize(QtCore.QSize(QtCore.QRect(0,0,400,300).size()).expandedTo(Dialog.minimumSizeHint()))
-
-
self.buttonBox = QtGui.QDialogButtonBox(Dialog)
-
self.buttonBox.setGeometry(QtCore.QRect(30,240,341,32))
-
self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
-
self.buttonBox.setStandardButtons(QtGui.QDialogButtonBox.Cancel|QtGui.QDialogButtonBox.NoButton|QtGui.QDialogButtonBox.Ok)
-
self.buttonBox.setObjectName("buttonBox")
-
-
self.okButton = QtGui.QPushButton(Dialog)
-
self.okButton.setGeometry(QtCore.QRect(70,70,80,27))
-
self.okButton.setObjectName("okButton")
-
-
self.retranslateUi(Dialog)
-
QtCore.QObject.connect(self.buttonBox,QtCore.SIGNAL("accepted()"),Dialog.accept)
-
QtCore.QObject.connect(self.buttonBox,QtCore.SIGNAL("rejected()"),Dialog.reject)
-
#QtCore.QObject.connect(self.okButton,QtCore.SIGNAL("clicked()"),self.bok0)
-
QtCore.QMetaObject.connectSlotsByName(Dialog)
-
-
#def bok0(self):
-
#print "OK !!!!!!!!"
-
-
def retranslateUi(self, Dialog):
-
Dialog.setWindowTitle(QtGui.QApplication.translate("Dialog", "Dialog", None, QtGui.QApplication.UnicodeUTF8))
-
self.okButton.setText(QtGui.QApplication.translate("Dialog", "New OK", None, QtGui.QApplication.UnicodeUTF8))
-
Now the main python code, which evokes the ui and tries to connect the OK button:
-
#!/usr/bin/env python
-
-
import sys
-
from PyQt4 import QtCore, QtGui
-
from untitled import Ui_Dialog
-
-
class TestDialog(QtGui.QDialog, Ui_Dialog):
-
def __init__(self):
-
QtGui.QDialog.__init__(self)
-
-
# Set up the user interface from Designer.
-
self.setupUi(self)
-
-
# Connect up the buttons.
-
self.connect(self.okButton, QtCore.SIGNAL("clicked"), self.bok)
-
-
@QtCore.pyqtSignature("")
-
def bok(self):
-
print "OK 2 !!!!!!!!"
-
-
if __name__ == '__main__':
-
app = QtGui.QApplication(sys.argv)
-
window = QtGui.QDialog()
-
ui = TestDialog()
-
ui.setupUi(window)
-
-
window.show()
-
sys.exit(app.exec_())
-
As I said, I must make a principal mistake here, as there is no output "OK 2!!!!" on my shell when I press the button. There is also no error message or crash or whatever nasty thing, it just doesn't work. However, if I uncomment the same type of code in the ui (bok0 function), then it works. But that's not what I want.
I would very much appreciate if there is somebody who could help me in this matter. Please feel free to tell me that I am stupid as I made a stupid mistake... no hard feelings ;-)
Cheers,
Michelle
