Here are the IDE events:

What are "instantiated" and "unassigned" forms?

Note that a LFM might need units, not in the uses clause. The IDE only
adds the units for the used component classes, not for the used
property values. So compiling might fail.
The TCompWriterPas has the full list of required units in the property
NeededUnits.
