wxPython与包装staticText的问题

wxPython与包装staticText的问题

我希望以Mike Driscoll的代码为基准，希望这能证明我的问题。使用“ txt”有两种不同的版本。这是我要您尝试的三件事：

1. 按原样运行。用我的StaticWrapText。一开始它显示错误，但是重新调整了窗口大小，并且完全可以按照我的要求工作。在“按钮”之前的文本下方没有空格/浪费空间

2. 更改这两行（更改注释）：
   txt = wx.StaticText（panel，label = text）
   

txt = StaticWrapText（panel，label = text）

现在您将看到没有换行，并且文本始终仅在一行上。绝对不是我们想要的。这是因为“ sizer.Add（txt，0，wx.EXPAND，5）”
…所以继续第3部分…

1. 保留对第2部分
   所做的更改，并将更改：sizer.Add（txt，0，wx.EXPAND，5）
   更改为：
   sizer.Add（txt，1，wx.EXPAND，5）
   现在，静态文本将扩展。这接近工作状态…但是我不想在文本和按钮之间浪费所有空白。如果将窗口放大，则会浪费大量空间。调整窗口大小后，请参阅第1部分，以了解差异。
   

码：

import wxclass StaticWrapText(wx.PyControl):   def __init__(self, parent, id=wx.ID_ANY, label='', pos=wx.DefaultPosition,     size=wx.DefaultSize, style=wx.NO_BORDER,     validator=wx.DefaultValidator, name='StaticWrapText'):      wx.PyControl.__init__(self, parent, id, pos, size, style, validator, name)      self.statictext = wx.StaticText(self, wx.ID_ANY, label, style=style)      self.wraplabel = label      #self.wrap()   def wrap(self):      self.Freeze()      self.statictext.SetLabel(self.wraplabel)      self.statictext.Wrap(self.GetSize().width)      self.Thaw()   def DoGetBestSize(self):      self.wrap()      #print self.statictext.GetSize()      self.SetSize(self.statictext.GetSize())      return self.GetSize()class MyForm(wx.frame):    def __init__(self):        wx.frame.__init__(self, None, wx.ID_ANY, "Tutorial")        # Add a panel so it looks the correct on all platforms        panel = wx.Panel(self, wx.ID_ANY)        text = "I'm subclasses the statictext because I want it to act exactly like a static text, but correctly wordwrap as needed. I've found several examples of it on the web, but none that worked how I wanted. The wordwrap makes it look much nicer when the user may decide to re-size the window, so I would definitely like to have it be wordwrapped. I know about the wx.lib.wordwrap, but chose to use the built in Wrap function of the statictext control instead. It basically does the same thing from what I understand."        #txt = wx.StaticText(panel, label=text)        txt = StaticWrapText(panel, label=text)        wxbutton = wx.Button(panel, label='Button', size=wx.Size(120,50))        sizer = wx.BoxSizer(wx.VERTICAL)        sizer.Add(txt,      0, wx.EXPAND, 5)        sizer.Add(wxbutton, 1, wx.EXPAND, 5)        panel.SetSizer(sizer)# Run the programif __name__ == "__main__":    app = wx.PySimpleApp()    frame = MyForm().Show()    app.MainLoop()

编辑：

AHHH
…终于！我实际上尝试在程序的每个级别上使用Layout（）方法，但实际上我需要在通过GetSizer（）方法找到的SIZER上使用Layout（）-否则您可以将SendSizeEvent（）发送到面板（注释在下面的代码中）。因此，以下内容完全符合我的要求！谢谢您的帮助。唯一的其他更改是将带有self.panel的面板存储在frame类中。注意，我必须在frame.Show（）之后放置此语句，否则它不能正常工作。

码：

import wxclass StaticWrapText(wx.PyControl):   def __init__(self, parent, id=wx.ID_ANY, label='', pos=wx.DefaultPosition,     size=wx.DefaultSize, style=wx.NO_BORDER,     validator=wx.DefaultValidator, name='StaticWrapText'):      wx.PyControl.__init__(self, parent, id, pos, size, style, validator, name)      self.statictext = wx.StaticText(self, wx.ID_ANY, label, style=style)      self.wraplabel = label      #self.wrap()   def wrap(self):      self.Freeze()      self.statictext.SetLabel(self.wraplabel)      self.statictext.Wrap(self.GetSize().width)      self.Thaw()   def DoGetBestSize(self):      self.wrap()      #print self.statictext.GetSize()      self.SetSize(self.statictext.GetSize())      return self.GetSize()class MyForm(wx.frame):    def __init__(self):        wx.frame.__init__(self, None, wx.ID_ANY, "Tutorial")        # Add a panel so it looks the correct on all platforms        self.panel = wx.Panel(self, wx.ID_ANY)        text = "I'm subclasses the statictext because I want it to act exactly like a static text, but correctly wordwrap as needed. I've found several examples of it on the web, but none that worked how I wanted. The wordwrap makes it look much nicer when the user may decide to re-size the window, so I would definitely like to have it be wordwrapped. I know about the wx.lib.wordwrap, but chose to use the built in Wrap function of the statictext control instead. It basically does the same thing from what I understand."        txt = StaticWrapText(self.panel, label=text)        wxbutton = wx.Button(self.panel, label='Button', size=wx.Size(120,50))        sizer = wx.BoxSizer(wx.VERTICAL)        sizer.Add(txt,      0, wx.EXPAND, 5)        sizer.Add(wxbutton, 1, wx.EXPAND, 5)        self.panel.SetSizer(sizer)# Run the programif __name__ == "__main__":    app = wx.PySimpleApp()    frame = MyForm()    frame.Show()    #frame.panel.SendSizeEvent()    frame.panel.GetSizer().Layout()    app.MainLoop()

最后一点，在我发布的原始程序中，需要在frame.Show（）之前或之后添加以下行：
frame.panel.Panel2.GetSizer（）。Layout（）

有趣的是…对于那个原始示例，它可以在frame.Show（）之前或之后，但是另一个示例要求它在frame.Show（）之后。我不知道为什么，但是把它放在后面就可以了。
