"At the proper time" == update()
Let's say you have a form displaying your Customers. It would be cool
if the form's Caption reflected the currently-selected customer, so to
do this you would write:
def afterInit(self):
self.DynamicCaption = self.getCurrentCustomer
def getCurrentCustomer(self):
return "Editing: %s" % self.PrimaryBizobj.Record.cust_name
Now as you navigate or requery, selecting a record fires the update()
method, causing all controls to display the current record's values,
and will also update the form's Caption property with the value
returned by getCurrentCustomer().
Other common uses are DynamicEnabled/DynamicVisible that are tied to
permissions; DynamicBack/ForeColor to highlight items that need
attention or to display a visual status cue; DynamicHeight/Width/Left/
Right to control sizing/positioning of an object to reflect some other
status/condition; ...
