Starting your first RAD Studio application Index (IDE Tutorial)
This section explains how to use the Rapid Application Development tools of Embarcadero RAD Studio to create a GUI (Graphical User Interface) application. You start with creating the main form, customizing it, and adding the necessary visual and nonvisual components.
The sections of code in the application to handle user actions are called event handlers, which you also need to implement. User events handled include clicking items under the menus and typing or clicking inside the edit window.
After following the steps, given both for Delphi and C++, you will have a basic text editor, with a few additional features like word-wrapping and the ability to change the font and display or the current cursor position in the status bar.
