python - 覆盖 mousePressEvent 后 Qt Widget 调整大小

转载作者：行者123 更新时间：2023-12-01 00:45:27

我正在尝试在 QtTreeView 小部件中实现上下文菜单。使用中的建议 Why mouseMoveEvent does nothing in PyQt5我创建了 QTreeView 的子类:

class TreeView(QTreeView):
def mousePressEvent(self, event):
    if event.type() == QEvent.MouseButtonPress:
        if event.button() == Qt.LeftButton:
            print( "Left click")
        elif event.button() == Qt.RightButton:
            print( "Right click")
        elif event.button() == Qt.MiddleButton:
            print( "Middle click")
    super(TreeView, self).mousePressEvent(event)

我将覆盖 QtTreeView(我在 Qt Designer 中设计的)，如下所示:

self.dockWidget.treeView = TreeView(self.dockWidget.treeView)

这可以工作并允许在 TreeView 中捕获 mousePressEvents，但它会更改 TreeView 中内容的大小:

当它应该看起来像:

Correct TreeView Size[3]

我尝试设置 SizePolicy:

self.dockWidget.treeView.setSizePolicy(QSizePolicy.Expanding,QSizePolicy.Expanding)

但这并没有什么区别。我正在寻找一种方法来防止它改变大小或在改变后将其恢复到原始大小。

最佳答案

您假设以下代码:

self.dockWidget.treeView = TreeView(self.dockWidget.treeView)

正在替换 Qt Designer 创建的 QTreeView，因为不，您只是创建另一个 QTreeView，它是原始 QTreeView 的子级。

您的逻辑类似于:

x = 10
y = x
x = 100

你认为 y 的值为 100，但显然不是。
