This gives you an interface defined in Delphi, an instance of which you can use in Delphi as though it was a Delphi object, but that is actually implemented in C++. Wesley Yamazack Batista teste Graduated in System Analysis, in business development for over six years, where he worked in companies of various segments such as financial, commercial, parking, etc. Barry explained how you can use that knowledge to put a delegate into a method pointer and Mason used the enhanced RTTI to get some details about them.

The synthesized samples are then used to train a classifier. However, you can adopt a second approach to customize how a component interacts with Delphi: write a custom component editor. class method ClassParent: TClass. For clarity, the IStream object defined in the Delphi Visual Component Library (VCL) is a dynamic object that doesn't have any methods, procedures, functions, etc until these methods are defined in your code. A class method doesn't have an object instance to act upon, because it can be applied to an object of the class or to the class as a whole. In the FormDestroy method, we can call the Free method of each object. Thanks in advance, object instead. Delphi uses RTTI to access the values of properties when saving and loading form (.
