fpGUI

│ English (en) │ español (es) │

fpGUI is a Object Pascal toolkit for cross-platform application development. It provides single-source portability across Linux, MS Windows, *BSD, Solaris/OpenSolaris, ReactOS and embedded devices like Embedded Linux and Windows CE. fpGUI Toolkit can be used for Open Source and Commercial applications.

fpGUI is a widgetset completely written in Object Pascal. It links directly with the underlying windowing system (Xlib, GDI), and thus avoids the need for many large external libraries (eg: Qt, GTK etc). The main design goal is to get a consistent look and behavior across platforms.

Latest release v1.4.1 (2015-09-02):

• http://fpgui.sourceforge.net

Documentation:

• http://fpgui.sourceforge.net/apidocs

Repository:

• https://github.com/graemeg/fpgui

Compile fpGUI code from terminal:

You may use a extrafpc.cfg file and @extrafpc.cfg as fpc parameter.

=> Example of extrafpc.cfg file (change fpGUI_dir according of your installation and save extrafpc.cfg in same directory as application-code):

-Fi/fpGUI_dir/src/
-Fi/fpGUI_dir/src/corelib/
-Fi/fpGUI_dir/src/corelib/x11/
-Fu/fpGUI_dir/src/
-Fu/fpGUI_dir/src/corelib/
-Fu/fpGUI_dir/src/gui/
-Fu/fpGUI_dir/src/corelib/x11/
-FUunits/
-FE./

And you may compile your fpGUI application like that :=>

> fpc myfpguiapp.pas @extrafpc.cfg

Compile fpGUI code from Lazarus:

Configure Lazarus for hosting pure fpGUI applications: =>

- in Package, => Open Package (.lpk)

Choose:

- for Windows : <fpgui>/src/corelib/gdi/fpgui_toolkit.lpk

- for Linux/FreeBSD/OSX : <fpgui>/src/corelib/x11/fpgui_toolkit.lpk

Compile the package.

Now you may compile pure fpGUI applications with Lazarus.

License

fpGUI uses the LGPL v2 license with a static linking exception - the same as the Free Pascal Compiler's RTL.

Support

A dedicated support newsgroup exists for fpGUI Toolkit. Connection details are as follows:

	Details
NNTP Server	geldenhuys.co.uk
Port	119
Group	fpgui.support

Any News Client (eg: Mozilla Thunderbird, XanaNews, Opera Mail etc) can be used to connect to the news group. This is by far the best option and gives you the freedom to use your preferred news client software.

In a pinch, there is also a HTML webnews interface. This interface has some limitations (eg: attachments), but is good enough to read and reply to messages when on the go via a web browser (smartphone or desktop). To access the HTML interface, visit the following URL: [http://geldenhuys.co.uk/webnews/]

Screenshots

This is a small sample of what the fpGUI Toolkit's new 2D graphics engine can do. Full sub-pixel accuracy, anti-aliased line drawing, anti-aliased text, alpha blending, fully customisable gradient and dash-line generator, gamma support etc. The 2D graphics engine is also fully implemented in Pascal, so no external libraries are required, and makes it very portable to other platforms.
