为什么树簿中的ScrolledPanel不自动调整大小？

Question

由于我需要滚动条，所以我用ScrolledPanel更改了默认面板，但是插入到ScrolledPanel中的内容并不会根据窗口的大小使其自动大小。

然后，我尝试创建一个默认面板，并通过BoxSizer插入其中的所有小部件，最后通过另一个BoxSizer插入ScrolledPanel中的这个面板，但是内容在不进行自动调整的情况下继续进行。

我还尝试了相反的方法，即我创建了一个标准面板，并使用ScrolledPanel插入了我的BoxSizers，但也没有工作。

另一个细节是，这个ScrolledPanels必须在TreeBook中，因为我有一个树来管理每个ScrolledPanel的调用。

我的代码：

我想要的是点击树中的一个项目，打开面板旁边的内容，根据窗口的大小调整内容大小(静态文本，静态文本)。

Answer 1

我不确定我是否正确理解，但：

• StaticText不会自动断线，所以即使“内部面板”调整正确，文本也是不可见的。您可能希望使用某种类型的TextCtrl，可能是一个富文本ctrl。
• 如果您有一个滚动面板，那么面板的内部有它所需的大小，而滚动面板只是添加滚动条。

因此，您需要的是:在MenuPanel中创建另一个面板，并在这个新面板的MenuPanel子块中创建所有小部件。然后为MenuPanel添加一个超大规模的处理程序。

    self.Bind(wx.EVT_SIZE, self.OnSize)

def OnSize(self, evt):
    evt.Skip(False)
    self.p.SetSize(evt.GetSize())

(- MenuPanel)。但这设置了面板的大小，因此永远不需要滚动条。您可能只想要垂直滚动条，只有在需要时才需要，对吗？然后，我可能会尝试设置窗口的宽度，只有在可能的情况下，或者设置宽度和非常大的高度，测量，并再次设置大小。
