Getting Started with Form-based Applications in Delphi 7

Introduction

The following topics will help you to use Delphi 7 to write simple form-based applications using buttons, edit boxes, labels and labelled edits. You will learn about the essential code and files that comprise an application and how to create an application from existing unit and form files. Our tutorial on form-based applications covers the access of variables, the calling of procedures, using a string grid, DBGrid, list box, combo box and several types of dialogue boxes, drawing on the canvas and displaying motion graphics based on a timer. (We demonstrate Lazarus for most examples in the tutorial but you should find them helpful for Delphi 7 because you use both IDEs in a very similar way).

In the instructions we will give the key combinations for actions where possible. This table shows ways of firing commonly used actions in the order they appear in the Delphi 7 menu structure.

Menu Action Button (showing tool-tip) Short-cut Key(s)
File > New > Application Create a new application New Items (Opens New Items dialogue) Alt+F then N then A
File > Open ... Open file Open file Alt+F then O

For the screenshots in the following topics we have dragged the dialogue boxes to convenient sizes, so do not expect yours to look exactly the same.
