Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The TForm class, which is an ancestor to TFormSettings, is, in turn, inherited from the TComponent class."

A block of code is set as follows:

Application.Initialize; 
Application.CreateForm(TFormMain, FormMain); 
Application.CreateForm(TFormSettings, FormSettings); 
Application.Run;

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold: 

const EL = #13; 
 
procedure TForm1.ButtonMultilineClick(Sender: TObject); 
begin 
  ShowMessage('Welcome!' + EL + 'Good morning!'); 
end; 

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "In the New Items window, make sure that the Delphi Projects node is selected, and double-click on the Console Application icon."
