Interface iobjectpicker
Unit
Declaration
type iobjectpicker = interface(inullinterface)
Description
This item has no description. Showing description inherited from inullinterface.
Base of MSEgui's "CORBA-style" interfaces (declared under {$interfaces corba} instead of the default COM-style {$interfaces com}): they carry no reference counting, so classes implementing them keep their usual create/destroy lifetime management instead of being freed implicitly when an interface variable goes out of scope. This avoids the pitfalls of mixing COM-style interface lifetime handling with normal object lifetime handling. Use getcorbainterface to fetch such an interface from an object instance.
