使用 GIF 和图像创建启动画面

Question

我想要一个包含图像和 GIF 的启动画面（gif 将位于图像之上）。

我已经这样做了，但我认为这不是一个好方法，并且由于我使用了计时器，所以我放弃了使用启动画面的想法。

如何避免使用计时器。

这是我的最后一个代码：

import time

from PyQt5.QtCore import QRect, QMetaObject, QCoreApplication, Qt
from PyQt5.QtGui import QMovie, QPixmap
from PyQt5.QtWidgets import QHBoxLayout, QLabel, QApplication, QWidget


class Ui_Form(QWidget):

    def __init__(self, parent=None):
        super(Ui_Form, self).__init__(parent)
        self.setObjectName("self")
        self.resize(400, 400)
        self.label = QLabel(self)
        self.label.setText("This is main application")
        self.label.setObjectName("label")

def showStartScreen():
    start = time.time()

    # PNG image
    img_path = f".../splash_image.PNG"
    image = QPixmap(img_path)

    # set layout in order to put GIF in above (on top) a word that are in splash image
    layout = QHBoxLayout()

    # big image for Splash screen
    image_container = QLabel()
    image_container.setWindowFlag(Qt.SplashScreen, Qt.FramelessWindowHint)
    image_container.setLayout(layout)
    image_container.setPixmap(image)

    # label for displaying GIF
    label_2 = QLabel()
    label_2.setStyleSheet("margin-bottom:21px; margin-right:21px")

    movie = QMovie(".../loading_text_border_animation.gif")
    label_2.setMovie(movie)

    layout.addWidget(label_2, 0, Qt.AlignRight | Qt.AlignBottom)
    movie.start()
    image_container.show()

    # My problem is here, As you can say i made a timer for 5s in order to keep that GIF moving,
    # so making splash screen here is pointless, because
    # for example if the app needs only 3s to start then we slow it down by 2s
    while time.time() < start + 5:
        app.processEvents()


if __name__ == "__main__":
    import sys

    app = QApplication(sys.argv)
    ui = Ui_Form()
    showStartScreen()
    ui.show()
    sys.exit(app.exec_())

一种可能的解决方案是使用 QTimer：

    image_container = QLabel()
    image_container.setAttribute(Qt.WA_DeleteOnClose) // <--
    image_container.setWindowFlag(Qt.SplashScreen, Qt.FramelessWindowHint)
    image_container.setLayout(layout)
    image_container.setPixmap(image)

    # ...

    layout.addWidget(label_2, 0, Qt.AlignRight | Qt.AlignBottom)
    movie.start()
    image_container.show()

    return image_container


if __name__ == "__main__":
    import sys

    app = QApplication(sys.argv)
    ui = Ui_Form()
    splash_screen = showStartScreen()
    QTimer.singleShot(5 * 1000, splash_screen.close)
    QTimer.singleShot(5000, ui.show)
    sys.exit(app.exec_())
