Python Code Examples

DoWhileUserIsIdle

//If you try to execute a script while holding down a modifier like ctrl or shift, it will postpone execution until you release the modifier
#python
import lx, lxifc
 
class visitor(lxifc.Visitor):                  
    def __init__(self):     # The initial setup method 
        pass
 
    def vis_Evaluate(self):

//Too cancel it you need to pass exactly the same com object and flags
