Of course, everything done in the designer can be done via source code at runtime too. Even embedding a form into another form as a subcomponent can be done visually. Descendants can be created visually that inherit from this dialog. For example, a base form can be created for all of an application's dialogs. The designer also allows you to inherit forms visually. No extra source code is required for this, just some mouse clicks. That means a component on form1 can access the components on form2. The IDE even supports connecting two designed forms.

Remove a method from the code, and the IDE will disconnect it from the designed form. No further work is needed-simply compile and run. For instance, double-clicking on a button in the designer automatically creates the OnClick in the source code and connects the button and the event handler. Lazarus' designer works directly with the corresponding Pascal unit source. The Lazarus IDE uses the LCL and has an integrated visual form designer, which allows you to edit forms graphically, like Glade or Trolltech's Qt Designer.

So, if you don't care about native widgets and you want your application to look and feel exactly the same on all platforms, you can make use of the LCL and the fpgui library, which currently runs on MS Windows, MS Windows CE and Linux with X.

Some other LCL interfaces are under development-for example, fpgui, a widget set written completely in Object Pascal and Cocoa for the new Mac OS X libraries. This allows you simply to copy a project developed under Linux to Windows and compile. The widget set can be chosen automatically by the IDE or selected manually in the dialog for the compiler options. Under Mac OS X, the choices are Carbon, GTK and Qt. For Windows CE, the back end is called wince. Under Windows, the choices are the WinAPI, GTK and Qt. The code itself needs to access only the LCL API, so no change is required when switching the widget set.Īn LCL application compiled with GTK creates a native GTK application running on most Linux distributions out of the box. The LCL calls the back-end widget sets and provides the glue between the platform-independent API and the widget set. Additionally, on Linux, you have the choice between GTK or Qt as a back end. These components run on Linux, MS Windows, Mac OS X, FreeBSD and Solaris using native widgets. Lazarus gives FPC a face by providing the Lazarus Component Library (LCL), a library of visual components, such as buttons, edit fields, file dialogs and much more.

At the time of this writing, the compiler is at version 2.2.4. The Free Pascal Compiler itself is written entirely in Object Pascal. After a while, you'll compile without thinking, just to highlight even obvious errors. This saves a lot of time, even for small programs, and allows you to be more productive. That is because in Object Pascal, forward declarations are more limited than in C/C++. The speed and size of the created code is comparable to GCC.įPC also compiles fast-normally more than 10,000 lines of code per second.

Free Pascal creates native code executables, like C and C++, and uses the GNU tools and object format, so it can use C libraries directly, and, of course, C/C++ code can use FPC libraries. You can find binaries, packages and daily snapshots at the Free Pascal and Lazarus Web sites (see Resources). It is available for the following operating systems: Linux, FreeBSD, Mac OS X/Darwin, DOS, Win32, Win64, WinCE, OS/2, Netware (libc and classic) and MorphOS, and for different processors: Intel x86, AMD64/x86_64, PowerPC, PowerPC64, SPARC and ARM.

Free Pascal (aka, FPK Pascal) is a 32- and 64-bit professional Object Pascal compiler. Lazarus uses the powerful Free Pascal Compiler (FPC), which understands Object Pascal (a descendant of Pascal).
