PyQt4 and MySQL I want to learn how to insert data using QLineEdit and QPushButton

Can someone please teach me how to insert data in MySQL using QLineEdit and QPushButton?

Do you have any piece of code so far? Its hard to guess where to start without knowing what you already have/know.

@the_ i want to enter a data in QlineEdit and pass it to my database how to do it?

Thanks for your code sniplet (i assume you use python2.x)

First of all in python the constructor is __init__(self) instead of init(self)

so using

class Window(QtGui.QMainWindow):
    def __init__(self):
        super(Window, self).__init__()
        self.setGeometry(50,50,0,0)
        self.setFixedSize(900,600)
        self.setWindowTitle("IMS Delta EarthMoving")
        self.setWindowIcon(QtGui.QIcon('delta.png'))
        pic = QtGui.QLabel(self)
        pic.setGeometry(240, -165, 698, 500)
        pic.setPixmap(QtGui.QPixmap(os.getcwd() + "/delta2.png"))

        self.Input()
        self.search()
        self.button()
        self.database()

and

lateron

def run():
    app = QtGui.QApplication(sys.argv)
    GUI = Window()
#show the GUI window
    GUI.show()
    sys.exit(app.exec_())

run()

brings your window to front

I will have a look at the rest of your code a bit later

@the_ i am looking forward for that thank you sir

Had some more time to look at your piece of code. One of the problem is, that the input fields you declare are not "visible" to other class methods.

A variable that is declared inside a method is only visible locally in this function, so you need to make it global.

class MyClass(QWidget):
  """
  Constructor
  """
  def __init__(self):
    initUI() #and whatever has to be called in here

  """
  A function that does all the ui setup
  """
  def initUI(self):
    self.label = Qlabel("",self)
    secondlabel = QLabel("",self)
    button = QPushButton("Click Me",self)
    button.clicked.connect(self.setTextValue)
  """
  the SLOT that is called on button click
  """
  def setTextValue(self):
    self.label.setText("Button Clicked")
    secondlabel.setText("Button Clicked") # this will throw an error, because secondlabel is not defined here

def main():
  app = QtGui.QApplication(sys.argv)
  mywindow = MyClass()
  sys.exit(app.exec_())

if __name__ == '__main__':
  main()

Also you may use a layout on your main window and put the widgets in this layout instead of moving them around with move()

@the_ Thank you so much for your help ^__^
