Hi
In PyQt5, we will consider another widget, groupbutton the QButtonGroup() class.
Ideal for use when we can combine different buttons in the same selection category.
As an example, we have 3 buttons named save, save as, exit without save.
We can use groupbutton here because its work is different but similar in category.
Our Example :
This is how we define our groubutton.
self.group_button = QButtonGroup()
We defined the method to be triggered when any of the buttons are clicked
self.group_button.buttonClicked[int].connect(self.handleClickGroupButton)
We added our widgets to our layout.
my_vertical_layout = QVBoxLayout() my_vertical_layout.addWidget(self.btn_save) my_vertical_layout.addWidget(self.btn_save_and_exit) my_vertical_layout.addWidget(self.btn_exit_without_save) my_vertical_layout.addWidget(self.result_label)
Result :
Full source code:
from PyQt5.QtWidgets import *
import sys
W_WIDTH = 400
W_HEIGHT = 250
W_X = 400
W_Y = 150
class MainFrame(QWidget):
def __init__(self):
super().__init__()
self.init()
def init(self):
self.group_button = QButtonGroup()
self.group_button.buttonClicked[int].connect(self.handleClickGroupButton)
self.btn_save = QPushButton("Save")
self.group_button.addButton(self.btn_save,1)
self.btn_save_and_exit = QPushButton("Save And Exit")
self.group_button.addButton(self.btn_save_and_exit,2)
self.btn_exit_without_save = QPushButton("Exit Without Save")
self.group_button.addButton(self.btn_exit_without_save,3)
self.result_label = QLabel("")
my_vertical_layout = QVBoxLayout()
my_vertical_layout.addWidget(self.btn_save)
my_vertical_layout.addWidget(self.btn_save_and_exit)
my_vertical_layout.addWidget(self.btn_exit_without_save)
my_vertical_layout.addWidget(self.result_label)
self.setGeometry(W_WIDTH, W_HEIGHT, W_X, W_Y)
self.setLayout(my_vertical_layout)
self.setWindowTitle("www.langpy.com | Python GUI Tutorial")
self.show()
def handleClickGroupButton(self,button_id):
for btn in self.group_button.buttons():
if btn is self.group_button.button(button_id):
self.result_label.setText("Clicked Button: " + btn.text())
app = QApplication(sys.argv)
win = MainFrame()
sys.exit(app.exec_())
