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:
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
更改这两行(更改注释): txt = wx.StaticText(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…
码:
import wx
class 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.@R_555_2419@Sizer(wx.VERTICAL)
sizer.Add(txt, 0, wx.EXPAND, 5)
sizer.Add(wxbutton, 1, wx.EXPAND, 5)
panel.SetSizer(sizer)
# Run the program
if __name__ == "__main__":
app = wx.PySimpleApp()
frame = MyForm().Show()
app.MainLoop()
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 wx
class 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.

txt = StaticWrapText(self.panel, label=text)
wxbutton = wx.Button(self.panel, label='Button', size=wx.Size(120,50))
sizer = wx.@R_555_2419@Sizer(wx.VERTICAL)
sizer.Add(txt, 0, wx.EXPAND, 5)
sizer.Add(wxbutton, 1, wx.EXPAND, 5)
self.panel.SetSizer(sizer)
# Run the program
if __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。
