Question

我有wx.Frame来调用wx.Dialog。

现在，他们都做了相应的工作并且开得很好。问题是，当他们这样做时，他们也打开一个小窗口＆＃34;它位于我框架的左上角，在那之后我无法使用鼠标自动调整框架大小。关闭dialog没有任何效果，因为那个小窗口仍然在那里。

在wx.Frame内，我有以下事件调用：

def OnTerminalSettings(self, event):
    """Open Terminal settings dialog"""
    dlg = TerminalSettingsDialog(self, wx.ID_ANY, "", settings=TerminalPanel(self).settings)
    dlg.ShowModal()
    dlg.Destroy()

和TerminalSettingsDialog wx.Dialog看起来像这样：

class TerminalSettingsDialog(wx.Dialog):
    """Simple dialog with common terminal settings."""

    def __init__(self, *args, **kwds):
        self.settings = kwds['settings']
        del kwds['settings']
        kwds["style"] = wx.DEFAULT_DIALOG_STYLE
        wx.Dialog.__init__(self, *args, **kwds)
        self.checkbox_echo = wx.CheckBox(self, wx.ID_ANY, "Local Echo")
        self.checkbox_unprintable = wx.CheckBox(self, wx.ID_ANY, "Show unprintable characters")
        self.radio_box_newline = wx.RadioBox(self, wx.ID_ANY, "Newline Handling", choices=["CR only", "LF only", "CR+LF"], majorDimension=0, style=wx.RA_SPECIFY_ROWS)
        self.button_ok = wx.Button(self, wx.ID_ANY, "OK")
        self.button_cancel = wx.Button(self, wx.ID_ANY, "Cancel")

        self.__set_properties()
        self.__do_layout()

        self.__attach_events()
        self.checkbox_echo.SetValue(self.settings.echo)
        self.checkbox_unprintable.SetValue(self.settings.unprintable)
        self.radio_box_newline.SetSelection(self.settings.newline)

    def __set_properties(self):
        self.SetTitle("Terminal Settings")
        self.radio_box_newline.SetSelection(0)
        self.button_ok.SetDefault()

    def __do_layout(self):
        sizer_2 = wx.BoxSizer(wx.VERTICAL)
        sizer_3 = wx.BoxSizer(wx.HORIZONTAL)
        sizer_4 = wx.StaticBoxSizer(wx.StaticBox(self, wx.ID_ANY, "Input/Output"), wx.VERTICAL)
        sizer_4.Add(self.checkbox_echo, 0, wx.ALL, 4)
        sizer_4.Add(self.checkbox_unprintable, 0, wx.ALL, 4)
        sizer_4.Add(self.radio_box_newline, 0, 0, 0)
        sizer_2.Add(sizer_4, 0, wx.EXPAND, 0)
        sizer_3.Add(self.button_ok, 0, 0, 0)
        sizer_3.Add(self.button_cancel, 0, 0, 0)
        sizer_2.Add(sizer_3, 0, wx.ALL|wx.ALIGN_RIGHT, 4)
        self.SetAutoLayout(1)
        self.SetSizer(sizer_2)
        sizer_2.Fit(self)
        sizer_2.SetSizeHints(self)
        self.Layout()

    def __attach_events(self):
        self.Bind(wx.EVT_BUTTON, self.OnOK, id = self.button_ok.GetId())
        self.Bind(wx.EVT_BUTTON, self.OnCancel, id = self.button_cancel.GetId())

    def OnOK(self, events):
        """Update data with new values and close dialog."""
        self.settings.echo = self.checkbox_echo.GetValue()
        self.settings.unprintable = self.checkbox_unprintable.GetValue()
        self.settings.newline = self.radio_box_newline.GetSelection()
        self.EndModal(wx.ID_OK)

    def OnCancel(self, events):
        """Do not update data, but rather close dialog."""
        self.EndModal(wx.ID_CANCEL)

我不知道这是否重要，但框架中有一个顶部wx.Panel，而wx.Panel又包含其他两个TerminalPanel。我希望能够在其中一个面板中安装一个终端。

我从PySerial examples获得了终端的代码，所以我猜他们的工作正常。

任何人都可以借给我一个手吗？

dlg = TerminalSettingsDialog(self, wx.ID_ANY, "", settings=TerminalPanel(self).settings)

此语句正在创建TerminalPanel的新实例，每次创建对话框实例时，该实例都是self的子项。那是你额外的窗口。如果你已经有TerminalPanel某个地方的实例，那么你应该从中获取设置对象，而不是创建一个新实例。

为什么在关闭wxPython中的对话框时会出现一个小窗口？
