要更改QGraphicsItem的填充图片,您可以使用setBrush方法。具体来说,您需要创建一个QBrush对象,并将其设置为QGraphicsItem的brush。QBrush对象可以使用QPixmap或QImage作为其填充。
以下是一个例子:
```python
from PyQt5.QtGui import QBrush, QPixmap
from PyQt5.QtWidgets import QGraphicsRectItem, QGraphicsScene, QGraphicsView
from PyQt5.QtCore import Qt
# 创建场景和视图
scene = QGraphicsScene()
view = QGraphicsView(scene)
# 创建矩形项
rect = QGraphicsRectItem(0, 0, 100, 100)
# 创建一个填充为图像的画刷
pixmap = QPixmap("path/to/image.png") # 替换为您的图像路径
brush = QBrush(pixmap)
# 将画刷设置为项的填充
rect.setBrush(brush)
# 将项添加到场景中
scene.addItem(rect)
# 显示视图
view.show()
```
在此示例中,我们创建了一个填充为图像的QBrush对象,并将其设置为QGraphicsRectItem的brush。然后,我们将QGraphicsRectItem添加到场景中,并将场景显示在QGraphicsView中。请注意,这只是一个示例。您可以使用类似的方法将任何QPixmap或QImage设置为QGraphicsItem的填充。
