I think we can all agree: components are essential elements of the Delphi environment. One of the most important features of Delphi is that we can use Delphi to create our own components.
We can derive a new component from any existing component, but the following are the most common ways to create components: modifying existing controls, creating windowed controls, creating graphic controls, subclassing Windows controls and creating nonvisual components. Visual or not, with or without property editor, from scratch...you name it.
Developing Delphi components isn't a simple task, it involves quite a bit of knowledge of the VCL. However, developing custom components is not an impossible task; writing components is just pure programming.
What are you waiting for? Everything about creating custom components in Delphi.
