是什么让wxpython TextCtrl水平填充

Question

我在水平TextCtrl中有一个BoxSizer。它的重量为1（重量为0的按钮旁边）。当我运行程序时，TextCtrl将保持固定宽度，旁边有空格，无论窗口大小如何。为什么呢？

以下是代码：

wxapp = wx.App()
wxFrame = wx.Frame(None, -1 , 'Switch Time Zones', (0,0),(340,64))
wxFrame.Centre()
mainBox = wx.BoxSizer(wx.VERTICAL)
wxFrame.SetSizer(mainBox)

...#A few things are added to mainBox

outputBox = wx.BoxSizer(wx.HORIZONTAL)
mainBox.Add(outputBox, 1, wx.ALIGN_BOTTOM)

...#A few things are added to other boxes

submitButton = wx.Button(wxFrame,label='solve:')
outputBox.Add(submitButton,0)
outputText = wx.TextCtrl(wxFrame)
outputText.SetEditable(False)
outputBox.Add(outputText,1)

wxFrame.Show()
wxapp.MainLoop()

Answer 1

mainBox.Add(outputBox, 1, wx.ALIGN_BOTTOM|wx.EXPAND)
