Actually it doesn't work in the case of a shared callback. I think a
callback needs to be able to reference the widget that the event
occured for. Here is a hackish solution but my question still remains
#!/usr/bin/python
from fltk import *
class MyButton(Fl_Button):
def __init__(self,x,y,w,h,label=None):
Fl_Button.__init__(self,x,y,w,h,label)
self.secret=""
class MyWindow(Fl_Window):
def __init__(self,x,y,w,h,label=None):
Fl_Window.__init__(self,x,y,w,h,label)
self.pack=Fl_Pack(0,0,w,h)
self.array=[] #create an empty array
for x in range(0,3):
self.array.append(MyButton(0,0,0,50))
self.array[x].callback(self.but_cb)
self.array[x].callback(self.but_cb, x) #pass x as userdata
self.array[x].secret=chr(65+x)
self.pack.end()
self.end()
def but_cb(self, widget, userdata):
widget.label("okay")#works because label is method of Fl_Widget
print self.array[userdata].secret #this works
#print widget.secret #this still pukes
win=MyWindow(200,200,200,200)
win.show()
Fl.run()

Leading whitespace matters! No more improperly indented code.
