Wxpython Sizer 位置

Question

我有下面的示例应用程序，其中有几个简单的大小调整器，由于某种原因，它们垂直居中，这是我不想要的（请参阅附件）。我希望 wxchoice sizer 位于窗口的顶部，而不是垂直的中间，即使调整窗口大小时，它也保持在那个位置，但我就是找不到答案。

import wx

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

        super(Mywin, self).__init__(parent, title=title)
        self.panel = wx.Panel(self)

        self.vbox = wx.BoxSizer(wx.VERTICAL)
        nm = wx.StaticBox(self.panel, -1, 'Drop List:')
        nmSizer = wx.StaticBoxSizer(nm, wx.VERTICAL)

        self.workflowList = ["choice 1", "choice 2"]
        nmbox = wx.BoxSizer(wx.HORIZONTAL)
        self.workflowChoice = wx.Choice(self.panel, choices=self.workflowList)

        self.vbox.Add(nmSizer, 0, wx.ALL | wx.EXPAND, 0)
        nmbox.Add(self.workflowChoice, 0, wx.ALL, 5)
        nmSizer.Add(nmbox, 0, wx.ALL, 5)

        self.btnSizer = wx.BoxSizer(wx.HORIZONTAL)
        self.buttonGo = wx.Button(self.panel, -1, "Go")

        self.buttonClose = wx.Button(self.panel, -1, "Quit")

        self.btnSizer.Add(self.buttonGo, 0, wx.ALL, 5)
        self.btnSizer.Add(self.buttonClose, 0, wx.ALL, 5)

        self.vbox.Add(nmSizer, 0, wx.ALL | wx.CENTER | wx.TOP, 5)
        self.vbox.Add(self.btnSizer, 0, wx.ALL | wx.CENTER, 5)

        self.panel.SetSizer(self.vbox)

        self.panel.Fit()
        self.Show()

app = wx.App()
Mywin(None, -1, 'Test App ')
app.MainLoop()

您正在将 StaticBox 添加到 StaticBoxSizer，因此它的内裤可能会发生变化。

尝试以下方法：

import wx

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

        super(Mywin, self).__init__(parent, id=id, title=title)
        self.panel = wx.Panel(self)

        self.vbox = wx.BoxSizer(wx.VERTICAL)
        nm = wx.StaticBoxSizer(wx.VERTICAL, self.panel, 'Drop List:')

        self.workflowList = ["choice 1", "choice 2"]
        self.workflowChoice = wx.Choice(self.panel, choices=self.workflowList)
        nm.Add(self.workflowChoice, 0, wx.ALL|wx.EXPAND, 5)

        self.vbox.Add(nm, 0, wx.ALL, 5) # Add the box to the sizer

        self.btnSizer = wx.BoxSizer(wx.HORIZONTAL)
        self.buttonGo = wx.Button(self.panel, -1, "Go")

        self.buttonClose = wx.Button(self.panel, -1, "Quit")

        self.btnSizer.Add(self.buttonGo, 0, wx.ALL, 5)
        self.btnSizer.Add(self.buttonClose, 0, wx.ALL, 5)

        self.vbox.Add(self.btnSizer, 0, wx.ALL|wx.EXPAND, 0)

        self.panel.SetSizer(self.vbox)

        self.Bind(wx.EVT_CLOSE, self.OnClose)
        self.buttonClose.Bind(wx.EVT_BUTTON, self.OnClose)
        self.Show()

    def OnClose(self, event):
        self.Destroy()

app = wx.App()
Mywin(None, -1, 'Test App ')
app.MainLoop()
