13	+	## Introduction
14	+
15	+	[[fpGUI]] is a widgetset completely written in Object Pascal. It links directly with the underlying windowing system, and thus avoids the need for many external libraries. More information on its website: <http://fpgui.sourceforge.net>
16	+
17	+	This page covers the fpGUI widgetset - a Lazarus LCL widget wrapping the fpGUI code. It is different from [[fpGUI\|pure fpGUI]] code.

53	+	## Creating your first LCL application with fpGUI
54	+
55	+	This is a step-by-step guide to build your first application with the fpGUI widgetset
56	+
57	+	1. Download the latest Lazarus from subversion and build it (not necessary if you downloaded a pre-compiled snapshot)
58	+	2. Download fpGUI source code from the SourceForge.net Git repository as follows:
59	+
60	+
61	+	```
62	+	git clone git://git.code.sf.net/p/fpgui/code
63	+	```
64	+
65	+	3. Make sure you switch the the maint branch of fpGUI.
66	+
67	+
68	+	```
69	+	git checkout maint
70	+	```
71	+
72	+	4. Now we need to make the Lazarus LCL find the fpGUI code.
73	+	1. Using Lazarus (trunk)
74	+	* Option 1)
75	+
76	+	Copy the 'src' directory from the fpGUI sources into your Lazarus directory as follows:
77	+
78	+
79	+	<fpgui>/src/ ⇒ <lazarus>/lcl/interfaces/fpgui/src/
80	+
81	+
82	+	* Option 2)
83	+
84	+	Use your file system's symbolic linking function to create a link the fpGUI src directory, to the correct location in Lazarus.
85	+	For example:
86	+
87	+
88	+	cd /opt/lazarus/lcl/interfaces/fpgui
89	+	ln -s /path/to/fpgui/src src
90	+
91	+
92	+	2. Using Lazarus 1.0.8 and earlier
93	+	* Option 1)
94	+
95	+	Supported on all platforms. Copy two directories and one file from the downloaded fpgui to lazarus
96	+
97	+
98	+	<fpGUI dir>/src/gui ⇒ lazarus/lcl/interfaces/fpgui/gui
99	+	<fpGUI dir>/src/corelib ⇒ lazarus/lcl/interfaces/fpgui/corelib
100	+	<fpGUI dir>/src/VERSION_FILE.inc ⇒ lazarus/lcl/interfaces/fpgui/VERSION_FILE.inc
101	+
102	+
103	+	* Option 2)
104	+
105	+	Linux or any other Unix type platforms. Create symbolic links from the fpGUI's corelib , gui directories and VERSION_FILE.inc to the Lazarus LCL directory as follows:
106	+
107	+
108	+	ln -s <fpGUI dir>/src/gui lazarus/lcl/interfaces/fpgui/gui
109	+	ln -s <fpGUI dir>/src/corelib lazarus/lcl/interfaces/fpgui/corelib
110	+	ln -s <fpGUI dir>/src/VERSION_FILE.inc lazarus/lcl/interfaces/fpgui/VERSION_FILE.inc
111	+
112	+
113	+	5. Now you need to recompile LCL for the LCL-fpGUI widgetset
114	+	1. Using Lazarus (trunk)
115	+	1. Start a new LCL application
116	+	2. Tell it to use the LCL-fpGUI widgeset by using the Additions and Overrides dialog. This can be found by selecting "Project Options -> Compiler Options -> Additions and Overrides". You can use the drop-down button menus in that dialog to define the following IDE Macros, or type them in by hand. For the fpGUIPlatform macro, only define one, dependent on the platform you are compiling for.
117	+	* define IDE Macro: LCLWidgetType := fpgui
118	+	* define IDE Macro: fpGUIPlatform := gdi(for Windows)
119	+	* define IDE Macro: fpGUIPlatform := x11(for Linux/FreeBSD)
120	+	3. Compile your project!
121	+	2. Using Lazarus 1.0.8 and earlier
122	+	1. Start a new LCL application
123	+	2. Open Lazarus, open the menu "Tools -> Configure Build Lazarus", select all options to None and LCL to Build+Clean, select fpGUI widgetset and rebuild it.
124	+	3. Go to the menu Compiler Options, select fpGUI as the widgetset
125	+	4. Compile your project!
126	+
127	+	## Implementation details
128	+
129	+	### Component mapping
130	+
131	+	This is a table indication which FPGUI controls are used to build each LCL control.
132	+
133	+	NOTE: This table is incomplete and out of date. Many other controls have already been implemented in LCL-fpGUI, but not listed in this table.
134	+
135	+
136	+
137	+	LCL Control \| FPGUI Control \| Comments
138	+	---\|---\|---
139	+	TPageControl \| TfpgPageControl \| \-
140	+	TButton \| TfpgButton \| \-
141	+	TBitBtn \| TfpgButton \| fpGUI's standard button class supports images.
142	+	TSpeedButton \| TfpgButton \| fpGUI's standard button class supports images and flat look etc.
