Class tdblookup1
Unit
Declaration
type tdblookup1 = class(tcustomdataedit, idblookupdispfieldlink, idbdispfieldlink)
Description
This item has no description. Showing description inherited from tmsecomponent.
Extends the FPC tcomponent with object linking facilities and the like; base of every MSEgui component. This unit, mseclasses, must be added to uses after classes in code that also uses a third-party unit expecting the plain FPC tcomponent (e.g. TPSScript.Create(TComponent)), since MSEgui forks the FPC classes unit.
