Example 2, Accessing internal DataInput
page from ScriptButton on DataInput page
def DataInputScriptButtonClick(Sender,Args):
#insert the button handler code
t=GetBaseTool(Args.name) #Args the a generic tool instance, get the BaseTool instance
di=t.getDataInput('Config') #get the BaseTool's 'Config' DataInput object
if di: #check if available, ie. config dialog is open
di.update() #refresh content
Example 3, Generic button click handling
in DataInput buttonsdef ButtonClicked(Sender,Args):
#Sender is the clicked button
#Insert the control on clicked code
di=Args.getDataInputByChild(Sender)
param=di.getParameterByChild(Sender)
#print di,param.group,param.name,Sender.caption
if param.name.find('Tower')>-1:

elif Sender.caption.find('+')>0:
print 'increasing %s for %s'%(param.group,param.name)
