What is Gambas Programming?
Gambas is a free and open-source programming language that aims to make programming easier and more accessible, especially for beginners. It's based on the Gambas Basic language, which is a dialect of the BASIC programming language. You can think of it as a user-friendly way to create applications for your Linux operating system.
Why should you consider Gambas?
- Easy to Learn: If you're new to programming, Gambas's syntax is relatively straightforward and resembles other popular languages like Python or JavaScript.
- Cross-Platform Development: Gambas can be used to create applications that work on various Linux distributions, including Ubuntu, Debian, Fedora, and more.
- GUI Development Made Simple: One of Gambas's key strengths is its ability to create graphical user interfaces (GUIs) easily. You don't need to worry about complex libraries or frameworks; you can design your application's user interface visually using the Gambas IDE.
- Object-Oriented Programming: While Gambas has roots in the procedural BASIC paradigm, it also supports object-oriented programming concepts, enabling you to build structured and modular programs.
Getting Started with Gambas
1. Installation:
- Installing Gambas is usually as simple as using your distribution's package manager. On Debian-based systems (like Ubuntu), you'd use the following command in your terminal:
sudo apt-get install gambas3
2. The Gambas IDE:
- Once installed, you'll have access to the Gambas IDE. This is where you write, edit, and execute your Gambas code. It's a powerful environment with features like code completion, debugging tools, and a visual form designer for building your application's interface.
3. Your First Gambas Program:
Let's start with a classic: a "Hello World" program.
Print "Hello World!"
- Save this code in a file named "hello.bas" (the file extension for Gambas programs).
- Open the file in the Gambas IDE.
- Click the "Run" button, and you should see "Hello World!" printed in the console.
Building a Simple GUI Application
1. Designing the Interface:
- Within the Gambas IDE, start a new project and choose "Form" as the type.
- This will open a visual form designer where you can add elements like buttons, text boxes, and labels. Let's add a button with the text "Click Me!" and a label to display a message.
2. Adding Functionality:
- Double-click the "Click Me!" button. This will open a code editor window where you can write the button's click event handler.
- Add the following code to display a message in the label when the button is clicked:
Label1.Text = "You clicked the button!"
3. Running Your Application:
- Save your project.
- Click the "Run" button, and your GUI application will launch. Click the "Click Me!" button, and the label's text will change as you defined.
