13	1		## Introduction
14	2
15	3		[[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	4
17	5		This page covers the fpGUI widgetset - a Lazarus LCL widget wrapping the fpGUI code. It is different from [[fpGUI\|pure fpGUI]] code.

53	41		## Creating your first LCL application with fpGUI
54	42
55	43		This is a step-by-step guide to build your first application with the fpGUI widgetset
56	44
57	45		1. Download the latest Lazarus from subversion and build it (not necessary if you downloaded a pre-compiled snapshot)
58	46		2. Download fpGUI source code from the SourceForge.net Git repository as follows:
59		-
60		-
61	47		```
62	48		git clone git://git.code.sf.net/p/fpgui/code
63	49		```
64	50
65	51		3. Make sure you switch the the maint branch of fpGUI.
66		-
67		-
68	52		```
69	53		git checkout maint
70	54		```
71	55
72	56		4. Now we need to make the Lazarus LCL find the fpGUI code.
73	57		1. Using Lazarus (trunk)
74	58		* Option 1)
75	59
76		-	~~Copy the 'src' directory from the fpGUI sources into your Lazarus directory as follows:~~
	60	+	Copy the 'src' directory from the fpGUI sources into your Lazarus directory as follows:
77	61
78	62
79		-	~~<fpgui>/src/ ⇒ <lazarus>/lcl/interfaces/fpgui/src/~~
80		-
	63	+	<fpgui>/src/ ⇒ <lazarus>/lcl/interfaces/fpgui/src/
81	64
	65	+
	66	+
82	67		* Option 2)
83	68
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:~~
	69	+	Use your file system's symbolic linking function to create a link the fpGUI src directory, to the correct location in Lazarus.
	70	+
	71	+	For example:
86	72
87	73
88		-	~~cd /opt/lazarus/lcl/interfaces/fpgui~~
89		-	~~ln -s /path/to/fpgui/src src~~
90		-
	74	+	cd /opt/lazarus/lcl/interfaces/fpgui
91	75
	76	+	ln -s /path/to/fpgui/src src
	77	+
	78	+
	79	+
92	80		2. Using Lazarus 1.0.8 and earlier
93	81		* Option 1)
94	82
95		-	Supported on all platforms. Copy two directories and one file from the downloaded fpgui to lazarus
	83	+	Supported on all platforms. Copy two directories and one file from the downloaded fpgui to lazarus
96	84
97	85
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		-
	86	+	<fpGUI dir>/src/gui ⇒ lazarus/lcl/interfaces/fpgui/gui
102	87
	88	+	<fpGUI dir>/src/corelib ⇒ lazarus/lcl/interfaces/fpgui/corelib
	89	+
	90	+	<fpGUI dir>/src/VERSION_FILE.inc ⇒ lazarus/lcl/interfaces/fpgui/VERSION_FILE.inc
	91	+
	92	+
	93	+
103	94		* Option 2)
104	95
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:~~
	96	+	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	97
107	98
108		-	~~ln -s <fpGUI dir>/src/gui lazarus/lcl/interfaces/fpgui/gui~~
109		-	~~ln -s <fpGUI dir>/src/corelib lazarus/lcl/interfaces/fpgui/corelib~~

	105	+
112	106
113	107		5. Now you need to recompile LCL for the LCL-fpGUI widgetset
114	108		1. Using Lazarus (trunk)
115	109		1. Start a new LCL application
116	110		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	111		* define IDE Macro: LCLWidgetType := fpgui
118	112		* define IDE Macro: fpGUIPlatform := gdi(for Windows)
119	113		* define IDE Macro: fpGUIPlatform := x11(for Linux/FreeBSD)
120	114		3. Compile your project!
121	115		2. Using Lazarus 1.0.8 and earlier
122	116		1. Start a new LCL application
123	117		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	118		3. Go to the menu Compiler Options, select fpGUI as the widgetset
125	119		4. Compile your project!
126	120
127	121		## Implementation details
128	122
129	123		### Component mapping
130	124
131	125		This is a table indication which FPGUI controls are used to build each LCL control.
132	126
133	127		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	128
135	129
136	130
137	131		LCL Control \| FPGUI Control \| Comments
138	132		---\|---\|---
139	133		TPageControl \| TfpgPageControl \| \-
140	134		TButton \| TfpgButton \| \-
141	135		TBitBtn \| TfpgButton \| fpGUI's standard button class supports images.
142	136		TSpeedButton \| TfpgButton \| fpGUI's standard button class supports images and flat look etc.
