BUTTON_EVENT_Unavailable
 

#Create main menu object
import vizmenu
menu = vizmenu.add()

#Align the menu in the enter of the top of the screen.
menu.setAlignment( vizmenu.CENTER )

#Scale the menu up
vizmenu.MENU_FONT_SIZE = 24

#Create five menu subjects
n1 = menu.add( 'n1' )
z1 = menu.add( 'z1' )

#Create sub-menu with label for n1
n_checkbox = n1.add( viz.CHECKBOX, 'n11' )
n_checkbox.setScale([3]*3)

#Create sub-menu with label for z1
z_checkbox_p = z1.add( viz.CHECKBOX, 'z11' )
z_checkbox_p.setScale([3]*3)

z_checkbox_n = z1.add( viz.CHECKBOX, 'z12' )
z_checkbox_n.setScale([3]*3)

def onButton_trigger(obj,state):

global z111
global z222

#judgement for z1
if obj == z_checkbox_p:
if state == viz.DOWN:
z111 = True
print 'zt1=',z111
else:
z111 = False

#judgement for z2
if obj == z_checkbox_n:
if state == viz.DOWN:
z222 = True
print 'zt2=',z222
else:
z222 = False
viz.callback(viz.BUTTON_EVENT, onButton_trigger)

def onButton_trigger2(obj,state):

global n11

#judgement for z1
if obj == n_checkbox:
if state == viz.DOWN:
n11 = True
print 'n11=',n11
else:
n11 = False

viz.callback(viz.BUTTON_EVENT, onButton_trigger2)

Why is the code only valid for the later viz.BUTTON_EVENT? But not both of them?

Please follow the guidelines for posting Vizard code. That way it will be easier for us to reproduce the problem and help.

Thanks

If you're going to use the viz.callback command to handle button events then you should set it up with one callback function. Another way to do this is using vizact.onbuttondown and vizact.onbuttonup. In this case, you should create separate callback functions for each button event:
