wx.StaticText's label does not contract using SetSizerAndFit()

Question

I’d like to place a filename after the file is chosen and contract it if the file name is too long. Here is my code:

import wx

class Dlg(wx.Dialog):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        self.input_pnl = wx.Panel(self)
        self.choose_input = wx.Button(self.input_pnl, label='Select')
        self.input_filename = wx.StaticText(self.input_pnl, style=wx.ST_ELLIPSIZE_END)
        self.input_szr = wx.BoxSizer(wx.HORIZONTAL)
        self.input_szr.AddMany([
            (wx.StaticText(self.input_pnl, label='File to analyze'), 0, wx.ALIGN_CENTER),
            (self.choose_input, 0, wx.LEFT|wx.RIGHT, 7),
            (self.input_filename, 0, wx.ALIGN_CENTER)
        ])
        self.input_pnl.SetSizer(self.input_szr)

        borderSizer = wx.BoxSizer(wx.VERTICAL)
        borderSizer.AddMany([
            (self.input_pnl, 0, wx.EXPAND|wx.ALL, 10),
            (wx.StaticText(self, label='Some example text to shift the border to the right'), 0, wx.ALL, 10)])
        self.SetSizerAndFit(borderSizer)

        self.choose_input.Bind(wx.EVT_BUTTON, self.on_choose_input)
    
    def on_choose_input(self, event):
        with wx.FileDialog(self, "Open", wildcard="Plain text (*.txt)|*.txt",
                    style=wx.FD_OPEN | wx.FD_FILE_MUST_EXIST) as fileDialog:

            if fileDialog.ShowModal() == wx.ID_CANCEL:
                return

            self.input_pathname = fileDialog.GetPath()
            self.input_filename.SetLabel(fileDialog.GetFilename())

if __name__ == "__main__":
    app = wx.App()
    dlg = Dlg(None)
    dlg.ShowModal()
    dlg.Destroy()
    app.MainLoop()

But the label is not contracted normally, supposedly, because of the SetSizerAndFit() method.

Calling Layout, once you’ve selected the filename works, on Linux at least.

You might also consider adding wx.RESIZE_BORDER to the dialog, so that the dialog is re-sizeable, as a last resort.

import wx

class Dlg(wx.Dialog):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        self.input_pnl = wx.Panel(self)
        self.choose_input = wx.Button(self.input_pnl, label='Select')
        self.input_filename = wx.StaticText(self.input_pnl, style=wx.ST_ELLIPSIZE_END)
        self.input_szr = wx.BoxSizer(wx.HORIZONTAL)
        self.input_szr.AddMany([
            (wx.StaticText(self.input_pnl, label='File to analyze'), 0, wx.ALIGN_CENTER),
            (self.choose_input, 0, wx.LEFT|wx.RIGHT, 7),
            (self.input_filename, 0, wx.ALIGN_CENTER)
        ])
        self.input_pnl.SetSizer(self.input_szr)

        borderSizer = wx.BoxSizer(wx.VERTICAL)
        borderSizer.AddMany([
            (self.input_pnl, 0, wx.EXPAND|wx.ALL, 10),
            (wx.StaticText(self, label='Some example text to shift the border to the right'), 0, wx.ALL, 10)])
        self.SetSizerAndFit(borderSizer)

        self.choose_input.Bind(wx.EVT_BUTTON, self.on_choose_input)

    def on_choose_input(self, event):
        with wx.FileDialog(self, "Open", wildcard="Plain text (*.txt)|*.txt",
                    style=wx.FD_OPEN | wx.FD_FILE_MUST_EXIST) as fileDialog:

            if fileDialog.ShowModal() == wx.ID_CANCEL:
                return

            self.input_pathname = fileDialog.GetPath()
            self.input_filename.SetLabel(fileDialog.GetFilename())
            self.Layout()

if __name__ == "__main__":
    app = wx.App()
    dlg = Dlg(None, style=wx.RESIZE_BORDER)
    dlg.ShowModal()
    dlg.Destroy()
    app.MainLoop()
