ControlContext :: addInputHelp - Add a Input help for a Multiline edit
In order to support user input in an edit field, a selection list can be displayed when detecting specific patterns in the input area. Input help pops up with a selection list that is displayed in the control sControl which must be defined in design class sClassName.
The help control pops up at current cursor position when one of the provided activation strings (sActivate) is recognized as user's input.
Any number of input help controls might be added to a control. When adding several input help controls, activation strings should differ. In order to be able to remove input help controls properly, control names for input help controls should differ.
The context refers to a DBBaseContext instance, which is the base class for all database context classes (Property, Instance, ObjectSpace and Database).
