How to use the LCL without the Lazarus IDE?
Requirements
Things you'll need: Free Pascal 2.4.4 Lazarus 0.9.30
Tested on Microsoft Windows XP SP3.
Introduction
You aren't forced to use the Lazarus IDE if you want to develop with the LCL. You can use it directly from the Free Pascal Compiler.
The installation process
First download the Free Pascal 2.4.4 and the Lazarus 0.9.30 and install them.
Our FPC install directory will be this
X:\FPC\2.4.4\
"X" is the drive letter
The Lazarus install directory will be this
X:\Lazarus\
Then copy the lcl folder.
Copy this folder:
X:\Lazarus\lcl
Paste it to this location:
X:\FPC\2.4.4\units\i386-win32\lcl
Now you can remove the Lazarus from your computer. In the next section we'll informa the FPC that the LCL's been installed.
The settings
Start the FP. Click on the Options menu and then the Directories menu item. Select the Units tab (default).
Add these directories:
X:\FPC\2.4.4\units\i386-win32\lcl X:\FPC\2.4.4\units\i386-win32\lcl\units\i386-win32 X:\FPC\2.4.4\units\i386-win32\lcl\widgetset X:\FPC\2.4.4\units\i386-win32\lcl\interfaces\win32
Then click on the Include files tab.
Add this directory:
X:\FPC\2.4.4\units\i386-win32\lcl\include
Now, you should be able to use the LCL. However, above should be done for all Modes in Options if you plan to switch the mode in the future. Somehow easier is to edit fp.cfg directly. In the next section we'll try out creating a form with a button on it.
The code
This is the base-code:
program lcl_base; {$mode objfpc} {$H+} uses Classes, Interfaces, Forms; //Interfaces is important BEGIN END.
First we'll create a form:
program lcl_base; {$mode objfpc} {$H+} uses Classes, Interfaces, Forms; //Interfaces is very important type TForm1 = class(TForm) end; //Our Form class var Form1: TForm1; //Declare the Form1 BEGIN Application.Initialize; Application.CreateForm(TForm1, Form1); Application.Run; //We do exactly the same as the Lazarus does END.
And then we'll create a nice button;
program lcl_base; {$mode objfpc} {$H+} uses Classes, Interfaces, Forms, StdCntrls; //Interfaces is very important type TForm1 = class(TForm) Button1: TButton; end; //Our Form class var Form1: TForm1; //Declare the Form1 BEGIN Application.Initialize; Application.CreateForm(TForm1, Form1); Button1 := TButton.Create(Form1); With Form1.Button1 Do Begin Parent := Form1; Visible := TRUE; Left := 10; Top := 10; Width := 100; Height := 100; Caption := 'PRESS ME'; End; Application.Run; //We do exactly the same as the Lazarus does END.
That's it. Now, you are able to use the LCL without the Lazarus IDE.
