Get a valur for make some calculates

[Andrea]

Hi all,

I have a little gui that provide 4 textctrl for insert some data.
After that the user insert the data I would like to do some operation
with this data like a * b = c but I receive some type error because I
don't have a int variables.

How can I get the value from GetValue() function and use thus like
integer or float number for do the calculates?

---Code---
...
...
self.local = wx.TextCtrl(self.panel, -1, '', pos = (200, 45))
self.scontolocal = wx.TextCtrl(self.panel, -1, '', pos = (200, 75))
...
...
 def OnCalculate(self, event):
    	tot_local = self.local.GetValue()
    	scontolocal_mr = self.scontolocal.GetValue()
    	sconto = (tot_local * scontolocal_mr)/100
    	res = tot_local - sconto
    	self.totscontato = wx.TextCtrl(self.panel, -1, res, pos = (200,
105))
...
...

Thanks
Andrea
