如何将cefpython浏览器对象绑定到wxpython中的BoxSizer？

Question

我使用 wxpython 创建了自定义最大化框架。在面板顶部，自定义关闭按钮和底部 cefpython 浏览器需要包含。为了分离，我使用了 BoxSizer。 CreateBrowserSync 正在返回浏览器对象，因此，我收到错误消息。

错误：

[CEF Python] ExceptHook: catched exception, will shutdown CEF

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/wx/core.py", line 2116, in Notify

    self.sizer.Add(self.browser, 1, wx.EXPAND)

代码

  window_info = cef.WindowInfo()
        (width, height) = self.browser_panel.GetClientSize().Get()
        assert self.browser_panel.GetHandle(), "Window handle not available yet"
        window_info.SetAsChild(self.browser_panel.GetHandle(),
                               [1, 1, width, height])

        self.browser = cef.CreateBrowserSync(window_info,
                                             url="https://www.google.com/")

self.sizer = wx.BoxSizer(wx.VERTICAL) 
    closeBtn = wx.Button(self, label="X", size=(30, 30))
    closeBtn.Bind(wx.EVT_BUTTON, self.onClose)
    vbox = wx.BoxSizer(wx.VERTICAL)
    hbox= wx.BoxSizer(wx.HORIZONTAL)
    hbox.Add(closeBtn, 0, flag=wx.ALIGN_RIGHT | wx.ALL)
    vbox.Add(hbox, 0, flag=wx.ALIGN_RIGHT | wx.ALL)
    self.SetSizer(vbox)
    vbox.SetSizeHints(self)
    self.sizer.Add(closeBtn, 0, wx.ALIGN_RIGHT | wx.ALL)
    sizer.Add(self.browser, 1, wx.EXPAND)
    self.SetSizer(sizer)

如何在 wxpython 中将 cefpython 浏览器对象绑定到 BoxSizer。如果有其他替代解决方案，请告诉我。

Answer 1

self.browser 变量包含一个 Python 对象，但BoxSizer.Add 方法需要一个小部件（面板、窗口等）作为第一个参数。

改变这一行：

sizer.Add(self.browser, 1, wx.EXPAND)

到这里：

sizer.Add(self.browser_panel, 1, wx.EXPAND)
