question about BUTTON_EVENT

[haohaoxuexi1]

checkbox = viz.addCheckbox(pos=(0.5,0.5,0))

def onButton(obj,state):
if obj == checkbox:
if state == viz.DOWN:
print 'Checked'
else:
pass

viz.callback(viz.BUTTON_EVENT,onButton)

checkbox2 = viz.addCheckbox(pos=(0.5,0.5,0))

def onButton1(obj,state):
if obj == checkbox2:
if state == viz.DOWN:
print 'Checked'
else:
pass

viz.callback(viz.BUTTON_EVENT,onButton1)


when i write the code as above, why is the system only execute the later BUTTON_EVENT but not both of them?

If i have two checkbox, should i put the judging condition in the same function?

I think this is expected behavior when two buttons are stacked on top of each other. What is the reason for having two buttons in the same position?

You could use the vizact.onbuttondown (http://docs.worldviz.com/vizard/#commands/vizact/onbuttondown.htm) command and register a callback function for each button.
