Buttons overlap each other

I have the following code:

    self.btn1 = wx.Button(self, -1, _("a"))
    self.btn2 = wx.Button(self, -1, _("b"))
    btnSizer = wx.BoxSizer(wx.HORIZONTAL)
    btnSizer.Add(self.btn1 , 0, wx.RIGHT, 10)
    btnSizer.Add(self.btn2 , 0, wx.RIGHT, 10)

This works well. However there is a case where I change the title of btn2 :

self.btn1.SetLabel('bbbbb')

When I do that btn1 overlaps btn2....

first row is the original second row is after set label.

enter image description here

How do I make the screen refresh to the new size of buttons?

Solution

  • You can use self.Layout() but in this case it really shouldn't be necessary. There must be some issue that you are having with your code.

    import wx

class ButtonFrame(wx.Frame):
    def __init__(self, value):
        wx.Frame.__init__(self,None)
        self.btn1 = wx.Button(self, -1, ("a"))
        self.btn2 = wx.Button(self, -1, ("b"))
        self.btnSizer = wx.BoxSizer(wx.HORIZONTAL)
        self.btnSizer.Add(self.btn1 , 0, wx.RIGHT, 10)
        self.btnSizer.Add(self.btn2 , 0, wx.RIGHT, 10)
        self.btn1.Bind(wx.EVT_BUTTON, self.OnPressA)
        self.btn2.Bind(wx.EVT_BUTTON, self.OnPressB)
        self.SetSizer(self.btnSizer)
        self.Centre()
        self.Show()

    def OnPressA(self,evt):
        self.btn1.SetLabel('bbbbbbbbbbbbbbbbbbbbbbbbbb')
#        self.Layout()

    def OnPressB(self,evt):
        self.btn2.SetLabel('aaaaaaaaaaaaaaaaaaaaaaaaaa')
#        self.Layout()

if __name__ == "__main__":
    app = wx.App(False)
    ButtonFrame(None)
    app.MainLoop()
