试试看:
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_())
示例 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_())
【讨论】:
self.splash = QSplashScreen(QPixmap('path/name.jpg'))。如果您的图像位于当前目录(您启动应用程序的位置),您可以简单地指定其名称self.splash = QSplashScreen(QPixmap('name.jpg'))
我喜欢在加载我的主小部件之前添加它并稍微淡化 - 请注意,这仅对显示徽标有用,如果您的应用程序加载时间很长,您可以使用像 @S. Nick 这样的启动屏幕如上所示,在您显示启动画面时允许加载时间:
if __name__ == "__main__":
app = QApplication([])
# Create splashscreen
splash_pix = QtGui.QPixmap('icons/Image.png')
splash = QtGui.QSplashScreen(splash_pix, QtCore.Qt.WindowStaysOnTopHint)
widget = Main()
# add fade to splashscreen
opaqueness = 0.0
step = 0.06
splash.setWindowOpacity(opaqueness)
splash.show()
while opaqueness < 1:
splash.setWindowOpacity(opaqueness)
time.sleep(step) # Gradually appears
opaqueness+=step
time.sleep(1.2)
splash.close()
# Run the normal application
widget.show()
app.exec_()
