如果您想让QComboBox的下拉菜单的样式与QMenu一样,可以使用QProxyStyle类来自定义QComboBox的样式。
以下是一个示例代码,可以实现将QComboBox的下拉菜单的样式设置为与QMenu相同:
```python
from PyQt5.QtWidgets import QApplication, QComboBox, QProxyStyle, QStyle
class CustomStyle(QProxyStyle):
def drawControl(self, element, option, painter, widget=None):
if element == QStyle.CE_ComboBoxDropDown:
# 将箭头图标修改为QMenu的箭头图标
option.subControls = QStyle.SC_ComboBoxArrow
super().drawControl(element, option, painter, widget)
app = QApplication([])
combo_box = QComboBox()
combo_box.addItems(['A', 'B', 'C'])
style = CustomStyle()
combo_box.setStyle(style)
combo_box.show()
app.exec_()
```
在这个示例中,我们创建了一个名为CustomStyle的自定义QProxyStyle类。在这个类中,我们覆盖了drawControl方法,并在其中判断如果元素是CE_ComboBoxDropDown(即下拉菜单的箭头),则将其subControls属性设置为SC_ComboBoxArrow(即QMenu的箭头)。然后我们将这个自定义样式应用到QComboBox上,这样就可以实现将QComboBox的下拉菜单的样式设置为与QMenu相同了。
