1 - Créer un Bouton PyQt5 avec la classe QPusButton
Pour créer un bouton de commande du type QPusButton, il suffit d'instancier la classe QPusButton:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
import sys from PyQt5.QtWidgets import QApplication, QWidget, QPushButton app = QApplication(sys.argv) win = QWidget() win.setGeometry(100 , 100 , 500 , 300) # create a QPusButton q_btn = QPushButton(win) q_btn.setText("This is a QPusButton ! ") q_btn.setGeometry(100 , 100 , 200 , 50) win.show() app.exec_() |
2 - Associer une action à un bouton QPushButton PyQt5
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
import sys from PyQt5.QtWidgets import QApplication, QWidget, QPushButton # create a button action def action(): print("Why you clicked the button !") app = QApplication(sys.argv) win = QWidget() win.setGeometry(100 , 100 , 500 , 300) # create a QPusButton q_btn = QPushButton(win) q_btn.setText("This is a QPusButton ! ") q_btn.setGeometry(100 , 100 , 200 , 50) # bind an action to the button q_btn.clicked.connect(action) win.show() app.exec_() |
Ce qui affiche à l'écran une fenêtre avec un bouton de commande et en cliquant sur ce dernier, on aperçoit l'affichage à l'écran du message:
Why you clicked the button !
