wxPython-按钮

Question

Here is my code:

for i in posortowane:
    z += 20
    result = '%s: %s' % (i[0], i[1])
    wx.StaticText(panel, -1, result, (345, 125 + z), style=wx.ALIGN_CENTRE)
    btn4 = wx.Button(panel, -1, u"Remove", (485, 120 + z))
    self.Bind(wx.EVT_BUTTON, self.Rem, btn4)

There are 2 buttons one below the other. They call Rem function:

def Rem(self, i):
    print i

I would like to write 'i' from 'posortowane' when I click button. It doesn't work. I tried:

self.Bind(wx.EVT_BUTTON, self.Rem(i), btn4)

but it calls Rem function before I click a button. How can I achieve this? I am sorry for my english. Thank you for any help.

Answer 1

When you add paranthesis, you are telling interpreter to call that function right away.
To pass parameters without calling callback immediatly, you should use lambda .

self.Bind(wx.EVT_BUTTON, lambda evt, i: self.Rem(evt,i), btn4)
