RE: [Win32Lib] Best way to get data from input controls

For most fields, I just get the text when it is needed (ie when the button 
is clicked)

If I have fields that have a restriction (ie numbers only), then I do this:
-----------------------------------------------------------------------------------------------------------------------------------
constant num_fields = <list of the controls with this restriction>

procedure number_field (integer self, integer event, sequence 
params)--params is ()
	object num
	num = value(getText(self) )
	if num[1] = GET_SUCCESS then
		setText(self,sprint(num[2]))
	else
		setText(self,"")
	end if
end procedure
setHandler( num_fields, w32HLostFocus, routine_id("number_field"))
