wxpython：在调整器内的面板中居中文本

在我看来，以下代码应该在窗口中央显示文本；即在内面板的中心。然而事实并非如此，我想知道为什么不。如果运行代码，您将在框架中间看到一个白色面板，大小为 150 像素 x 150 像素。我根本不希望该区域的大小发生变化，但是当我开始添加一些文本（取消注释片段中间的 txt 变量）时，面板总是会缩小以适合文本。即使指定 StaticText 的大小来匹配面板也不是解决方案，因为文本不会居中对齐。

import wx

class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title)




        self.rootPanel = wx.Panel(self)

        innerPanel = wx.Panel(self.rootPanel,-1, size=(150,150), style=wx.ALIGN_CENTER)
        innerPanel.SetBackgroundColour('WHITE')
        hbox = wx.BoxSizer(wx.HORIZONTAL) 
        vbox = wx.BoxSizer(wx.VERTICAL)

        # I want this line visible in the CENTRE of the inner panel
        #txt = wx.StaticText(innerPanel, id=-1, label="TEXT HERE",style=wx.ALIGN_CENTER, name="")

        hbox.Add(innerPanel, 0, wx.ALL|wx.ALIGN_CENTER)
        vbox.Add(hbox, 1, wx.ALL|wx.ALIGN_CENTER, 5)

        self.rootPanel.SetSizer(vbox)
        vbox.Fit(self)

class MyApp(wx.App):
    def OnInit(self):
        frame = MyFrame(None, -1, 'wxBoxSizer.py')
        frame.Show(True)
        frame.Center()
        return True

app = MyApp(0)
app.MainLoop()

It seems to me that the following code should display text right in the centre of the window; that is, in the centre of the inner panel. It doesn't however, and I'm wondering why not. If you run the code, you'll see a white panel in the middle of the frame, 150px by 150px. I do not want this area to change in size at all, but when I go about adding some text (uncommenting the txt variable in the middle of the snippet)the panel invariably shrinks to fit the text. Even specifying the size of the StaticText to match the panel isn't a solution because the text doesn't then centre-align.

import wx

class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title)




        self.rootPanel = wx.Panel(self)

        innerPanel = wx.Panel(self.rootPanel,-1, size=(150,150), style=wx.ALIGN_CENTER)
        innerPanel.SetBackgroundColour('WHITE')
        hbox = wx.BoxSizer(wx.HORIZONTAL) 
        vbox = wx.BoxSizer(wx.VERTICAL)

        # I want this line visible in the CENTRE of the inner panel
        #txt = wx.StaticText(innerPanel, id=-1, label="TEXT HERE",style=wx.ALIGN_CENTER, name="")

        hbox.Add(innerPanel, 0, wx.ALL|wx.ALIGN_CENTER)
        vbox.Add(hbox, 1, wx.ALL|wx.ALIGN_CENTER, 5)

        self.rootPanel.SetSizer(vbox)
        vbox.Fit(self)

class MyApp(wx.App):
    def OnInit(self):
        frame = MyFrame(None, -1, 'wxBoxSizer.py')
        frame.Show(True)
        frame.Center()
        return True

app = MyApp(0)
app.MainLoop()

您只需要添加几个垫片即可使其发挥作用。

import wx

class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title)

        self.rootPanel = wx.Panel(self)

        innerPanel = wx.Panel(self.rootPanel,-1, size=(150,150), style=wx.ALIGN_CENTER)
        innerPanel.SetBackgroundColour('WHITE')
        hbox = wx.BoxSizer(wx.HORIZONTAL) 
        vbox = wx.BoxSizer(wx.VERTICAL)
        innerBox = wx.BoxSizer(wx.VERTICAL)

        # I want this line visible in the CENTRE of the inner panel
        txt = wx.StaticText(innerPanel, id=-1, label="TEXT HERE",style=wx.ALIGN_CENTER, name="")
        innerBox.AddSpacer((150,75))
        innerBox.Add(txt, 0, wx.CENTER)
        innerBox.AddSpacer((150,75))
        innerPanel.SetSizer(innerBox)

        hbox.Add(innerPanel, 0, wx.ALL|wx.ALIGN_CENTER)
        vbox.Add(hbox, 1, wx.ALL|wx.ALIGN_CENTER, 5)

        self.rootPanel.SetSizer(vbox)
        vbox.Fit(self)

class MyApp(wx.App):
    def OnInit(self):
        frame = MyFrame(None, -1, 'wxBoxSizer.py')
        frame.Show(True)
        frame.Center()
        return True

app = MyApp(0)
app.MainLoop()

You just need to add a couple spacers to make it work.

import wx

class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title)

        self.rootPanel = wx.Panel(self)

        innerPanel = wx.Panel(self.rootPanel,-1, size=(150,150), style=wx.ALIGN_CENTER)
        innerPanel.SetBackgroundColour('WHITE')
        hbox = wx.BoxSizer(wx.HORIZONTAL) 
        vbox = wx.BoxSizer(wx.VERTICAL)
        innerBox = wx.BoxSizer(wx.VERTICAL)

        # I want this line visible in the CENTRE of the inner panel
        txt = wx.StaticText(innerPanel, id=-1, label="TEXT HERE",style=wx.ALIGN_CENTER, name="")
        innerBox.AddSpacer((150,75))
        innerBox.Add(txt, 0, wx.CENTER)
        innerBox.AddSpacer((150,75))
        innerPanel.SetSizer(innerBox)

        hbox.Add(innerPanel, 0, wx.ALL|wx.ALIGN_CENTER)
        vbox.Add(hbox, 1, wx.ALL|wx.ALIGN_CENTER, 5)

        self.rootPanel.SetSizer(vbox)
        vbox.Fit(self)

class MyApp(wx.App):
    def OnInit(self):
        frame = MyFrame(None, -1, 'wxBoxSizer.py')
        frame.Show(True)
        frame.Center()
        return True

app = MyApp(0)
app.MainLoop()
