How to delete a button using PYQT4?

Question

I am trying to delete this button

btn = QtGui.QPushButton("Log in", self)
btn.clicked.connect(self.remove)

When the button is clicked, it should disappear,but this doesn't work

btn.deleteQPushButton()

Or if there's any way to entirely delete every button in the window?

Answer 1

An elegant solution is to use deleteLater() :

btn = QtGui.QPushButton("Log in", self)
btn.clicked.connect(btn.deleteLater)

Answer 2

Yep, use deleteLater

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QHBoxLayout, QPushButton

if __name__ == '__main__':

    app = QApplication(sys.argv)

    wMain = QWidget()
    wMain.resize(250, 150)
    wMain.setWindowTitle('Main')
    wMain.show()

    centralLayout = QHBoxLayout(wMain)
    wMain.setLayout(centralLayout)

    button = QPushButton('Delete me',wMain)
    button.clicked.connect(button.deleteLater)
    centralLayout.addWidget(button)

    sys.exit(app.exec_())
