![]() ![]() The VCL is fundamentally a group of objects that descend from the abstractclass TObject. ![]() ![]() The remainder of this topic will take a very brief look at the hierarchy ofVCL objects in general. You can spendmore time building the working blocks of your application rather than having tospend repetitive time with the framework of each Windows application youdevelop. Obviously, writing code is required to make theapplication fully functional, but the VCL handles most of the work for you,making application development very expedient and more enjoyable. A developer can dropcomponents onto a form and have a working Windows application almost withoutwriting a single line of code. This architecture is joined with the Component Palette,Object Inspector, and IDE, giving developers a rapid approach to buildingapplications known as Rapid Application Development (RAD). The VCL is based on what is known as the PME model, including properties,methods, and events. The explanation is simple: The VCL is muchmore than objects descending from other objects. What you can't see, however,is the true complexity of the VCL. Not surprisingly, this chart hasexpanded with each new version of C++Builder. Supplied with C++Builder is a chart that schematically represents the VisualComponent Library (VCL) object hierarchy.
