是什么让wxpython TextCtrl水平填充

Question

我有TextCtrl一个水平的BoxSizer。它的权重为1（权重为0的按钮旁边）。当我运行该程序TextCtrl时，无论窗口的大小如何，它将保持固定的宽度，并在其旁边留有空白。为什么？

这是代码：

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()
