您可以使用以下代码在QTdesigner中为QTreeWidget滚动条设置弹出菜单样式:
```python
from PyQt5.QtGui import QStandardItemModel
from PyQt5.QtWidgets import QTreeView, QMenu, QAction
from PyQt5 import QtCore
class CustomTree(QTreeView):
def __init__(self, parent=None):
super(CustomTree, self).__init__(parent)
self.setModel(QStandardItemModel())
self.setContextMenuPolicy(QtCore.Qt.CustomContextMenu)
self.customContextMenuRequested.connect(self.showContextMenu)
self.menu = QMenu(self)
self.menu.setStyleSheet("QMenu {background-color: #f0f0f0;}")
self.scrollAction = QAction("滚动至此", self)
self.scrollAction.triggered.connect(self.scroll_to_item)
self.menu.addAction(self.scrollAction)
def showContextMenu(self, position):
index = self.indexAt(position)
if index.isValid() and self.model().hasChildren(index):
self.menu.exec_(self.viewport().mapToGlobal(position))
def scroll_to_item(self):
index = self.currentIndex()
if index.isValid():
self.scrollTo(index, self.PositionAtCenter)
```
在QTdesigner中,将QTreeWidget的类更改为CustomTree,并将其添加到您的窗口中。现在,当您右键单击QTreeWidget的滚动条时,将弹出一个菜单,您可以选择滚动至该位置。您可以使用CSS样式表为该弹出菜单设置样式。在上面的代码中,我已经为其设置了背景颜色为#f0f0f0。
