可以使用QPropertyAnimation来实现pyqt5的翻转动画切换显示stackedwidget。以下是示例代码:
```python
from PyQt5.QtCore import QPropertyAnimation, QRect
from PyQt5.QtWidgets import QApplication, QStackedWidget, QWidget, QVBoxLayout, QPushButton
class FlipWidget(QWidget):
def __init__(self, parent=None):
super(FlipWidget, self).__init__(parent)
self.frontWidget = QWidget(self)
self.backWidget = QWidget(self)
self.frontWidget.setStyleSheet("background-color: red;")
self.backWidget.setStyleSheet("background-color: blue;")
self.frontWidget.setGeometry(0, 0, 200, 200)
self.backWidget.setGeometry(0, 0, 200, 200)
self.frontWidget.show()
self.backWidget.hide()
self.animation = QPropertyAnimation(self, b"geometry")
self.animation.setDuration(500)
self.animation.setStartValue(QRect(0, 0, 200, 200))
self.animation.setEndValue(QRect(0, 0, 200, 200))
self.animation.setKeyValueAt(0.5, QRect(100, 0, 0, 200))
self.animation.finished.connect(self.flip)
self.isFlipped = False
def flip(self):
if self.isFlipped:
self.frontWidget.show()
self.backWidget.hide()
else:
self.frontWidget.hide()
self.backWidget.show()
self.isFlipped = not self.isFlipped
def startAnimation(self):
self.animation.start()
class MainWindow(QWidget):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.stack = QStackedWidget(self)
self.stack.addWidget(FlipWidget(self.stack))
self.stack.addWidget(FlipWidget(self.stack))
self.stack.addWidget(FlipWidget(self.stack))
self.stack.addWidget(FlipWidget(self.stack))
self.stack.setCurrentIndex(0)
layout = QVBoxLayout(self)
layout.addWidget(self.stack)
button = QPushButton("Next", self)
button.clicked.connect(self.next)
layout.addWidget(button)
def next(self):
index = self.stack.currentIndex()
if index == self.stack.count() - 1:
index = 0
else:
index += 1
self.stack.setCurrentIndex(index)
self.stack.currentWidget().startAnimation()
if __name__ == "__main__":
app = QApplication([])
window = MainWindow()
window.show()
app.exec_()
```
这个示例代码演示了如何使用QPropertyAnimation实现翻转动画切换显示stackedwidget。在这个示例中,我们创建了一个FlipWidget类,它包含了两个QWidget:frontWidget和backWidget。我们使用QPropertyAnimation来控制FlipWidget的geometry属性,从而实现翻转动画。在FlipWidget的flip方法中,我们根据当前的状态来显示或隐藏frontWidget和backWidget。在MainWindow中,我们创建了一个QStackedWidget,并将多个FlipWidget添加到其中。我们还添加了一个按钮,用于切换当前显示的FlipWidget。
