Overview of this book

A good integrated development environment can be the key to creating and delivering software on time and budget. Having a programming language and a development environment that runs on multiple platforms greatly eases and lessens the time taken on creating cross-platform applications. An IDE that is compatible with a legacy code base allows developers to leverage existing libraries in future applications."Getting Started with Lazarus" is a practical, hands-on guide that provides you with a number of clear step-by-step exercises, which will help you take advantage of the power of the Lazarus IDE and Free Pascal to develop software that can be created for cross-platform use."Getting started with Lazarus" discusses developing software with the open source cross platform integrated development environment and the Free Pascal language. We'll learn how to install Lazarus on various platforms such as Linux and Windows, as well as how to create new projects and convert existing Delphi projects to Lazarus projects by learning the differences between Delphi's Pascal syntax and Free Pascal's Object Pascal using a real world example project. We'll learn how to create custom components for use in Lazarus. We'll also learn the basics of documenting a Lazarus project using the Lazarus Documentation Editor. Finally we will learn that the IDE can be rebuilt using a different widget type, specifically GTK 2. Teach yourself the basics of programming with Lazarus and the open source IDE for the Free Pascal language.

Examining existing source documentation


When you run the application, you should be presented with a window similar to the following screenshot:

To become familiar with the LazDE tool, let us first open an existing documentation file.

  1. Click on the File menu and choose Open from the submenu.

  2. Browse to the directory in which Lazarus is installed, and select the /docs/xml/lcl subdirectory.

  3. Select the file buttons.xml and click on the Open button.

In the upper-left corner of the LazDE window is a treeview with the label Documentation Structure. You should now see a new node titled Packages. The steps to be followed are:

  1. Click the plus sign next to the new node to expand it.

  2. The node titled lcl is now visible. Expand this node.

  3. Now the node titled Buttons is visible; click on this node title.

The treeview Elements for selected node will now populate with the names of constants, types, and classes defined in the buttons.xml unit, as seen in the following screenshot. Other units that use the buttons unit...
