Splash screen in pyqt

解决方案

Try it:

import sys
from PyQt5.QtGui import QPixmap
from PyQt5.QtWidgets import QDialog, QPushButton, QVBoxLayout, QApplication, QSplashScreen 
from PyQt5.QtCore import QTimer

class Dialog(QDialog):
    def __init__(self, parent=None):
        super(Dialog, self).__init__(parent)

        self.b1 = QPushButton('Display screensaver')
        self.b1.clicked.connect(self.flashSplash)

        layout = QVBoxLayout()
        self.setLayout(layout)
        layout.addWidget(self.b1)

    def flashSplash(self):
        self.splash = QSplashScreen(QPixmap('D:/_Qt/img/pyqt.jpg'))

        # By default, SplashScreen will be in the center of the screen.
        # You can move it to a specific location if you want:
        # self.splash.move(10,10)

        self.splash.show()

        # Close SplashScreen after 2 seconds (2000 ms)
        QTimer.singleShot(2000, self.splash.close)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    main = Dialog()
    main.show()
    sys.exit(app.exec_())

Example 2

import sys
from PyQt5 import QtCore, QtGui, QtWidgets     # + QtWidgets


import sys
from PyQt5.QtWidgets import QApplication, QLabel
from PyQt5.QtCore    import QTimer, Qt

if __name__ == '__main__':
    app = QApplication(sys.argv)

    label = QLabel("""
            <font color=red size=128>
               <b>Hello PyQt， The window will disappear after 5 seconds！</b>
            </font>""")

    # SplashScreen - Indicates that the window is a splash screen. This is the default type for .QSplashScreen
    # FramelessWindowHint - Creates a borderless window. The user cannot move or resize the borderless window through the window system.
    label.setWindowFlags(Qt.SplashScreen | Qt.FramelessWindowHint)
    label.show()

    # Automatically exit after  5 seconds
    QTimer.singleShot(5000, app.quit) 
    sys.exit(app.exec_())
