Pycharm: Python Qt code code completion

Question

I am a beginner with Qt in Python.

I create simple from using Qt Designer.

Answer 1

1) generate python code: pyuic4 -o mygui.py mygui.ui

2) write code:

import sys
from PyQt4 import QtCore, QtGui
from mygui import Ui_MainWindow

class StartQT4(QtGui.QMainWindow):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        QtCore.QObject.connect(self.ui.pushButton, QtCore.SIGNAL("clicked()"), self.abc)

    def abc(self):
        input = self.ui.lineEdit.text()
        self.ui.label_2.setText(input)

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = StartQT4()
    myapp.show()
    sys.exit(app.exec_())

It works, but is possible to write QtCore.QObject.connect(self.ui.pushButton, QtCore.SIGNAL("clicked()"), self.abc) simpler?
