# example 1  label:

from PyQt5.QtWidgets import *
from PyQt5.QtGui import QFont

app=QApplication([])
window=Qwidget()
window.setGeometry(100,100,200,300) window coordinate and dimmentions
window.setWindowTitle(“Houssam App”)

label=QLabel(window)
label.setText(“hello world”)
label.setFont(QFont(“Arial”,16))
label.move(50,100)      #coordinate of label

window.show()
app.exec_()

if __name__ == ‘ __main__’:
    main()



# example 2 layout QVBoxLayout and push button
# and label and text box:

from PyQt5.QtWidgets import *
from PyQt5.QtGui import QFont

app=QApplication([])
window=Qwidget()
window.setGeometry(100,100,200,300) 
window.setWindowTitle(“Houssam App”)

label = QLabel(“Press the button “)
textbox=QTextEdit()
button = QPushButton(“Press Me !”)
button.clicked.connect(on_click)
button2 = QPushButton(“send msg”)
button2.clicked.connect(lambda: on_click2(textbox.toPlainText()))

layout.addWidget(label)
layout.addWidget(button)
layout.addWidget(button2)
layout.addWidget(textbox)
window.setLayout(layout)



window.show()
app.exec_()

def on_click():
    print(“Hello world”)
    message = QMessageBox()
    message.setText(“Hello world”)
    message.exec_()

def on_click2(msg):
    message.setText(msg)
    message.exec_()
    

if __name__ == ‘ __main__’:
    main()

QT Designer :

from PyQt5.QtWidgets import *
from PyQt5 import uic

class MyGUI(QMainWindow):
    def __init__(self):
        super(MyGUI,self).__init__()
        uic.loadUi(“mygui.ui” , self) # mygui.ui is the file from QT Designer
        self.show()
        
        self.pushButton.clicked.connect(self.login) # if pushButton is pushed
        self.pushButton_2.clicked.connect(lambda: self.sayit(self.textEdit.toPlainText()
        self.actionClose.triggered.connect(exit)

def login(self):
    if self.lineEdit.text() == “hrassi” and self.lineEdit_2.text() == “password”:
        self.textEdit.setEnabled(True)
        self.pushButton_2.setEnabled(True)
    else:
        message = QMessageBox()
        message.setText(“invalid login”)
        message.exec_()

def sayit(self, msg):
    message = QMessageBox()
    message.setText(msg)
    message.exec_()


def main():
    app = QApplication([])
    window = MyGUI()
    app.exec_()

if __name__ == ‘ __main__’:
    main()
