def onButton_trigger(obj,state):

#judgement for x axis
if obj == r_checkbox_x:
if state == viz.DOWN:
print "state=down"

else:
print "state=up"

#judgement for y axis
if obj == r_checkbox_y:
if state == viz.DOWN:
print "state=down"

else:
print "state=up"

#judgement for z axis
if obj == r_checkbox_z:
if state == viz.DOWN:
print "state=down"

else:
print "state=up"

viz.callback(viz.BUTTON_EVENT, onButton_trigger)



is that possible to set up some limit to guarantee that there is only one "obj" to be checked?

For example, when obj == r_checkbox_z state is down, the states of obj == r_checkbox_x, obj == r_checkbox_y are up.

The states of the three cannot be "up" at the same time.

Yes, each time one checkbox is changed by the user, you could use the button.set (http://docs.worldviz.com/vizard/#commands/node3d/GUI/button/set.htm) command to change the states of the other checkboxes.
