=== First start ===

In this page, we are going to see how to create quickly a frame incuding a button just to see how it is easy to do it using '''GENIUS'''.

After that, you just will have to follow the next pages to get explanations with more and more details and functionalities ...

To illustrate this example, we started using [http://www.eclipse.org/ Eclipse] environment but, of course, you are allowed to use any other environment to use '''GENIUS'''. Anyway, we considered that the user owns basic knowledege of Java langage and environment and we will not describe, for example, what is a class and how to create it !

=== Opening Eclipse and creating a project ===

First, we will have to create a Java project. Practically, it could be more interesting to create a [https://maven.apache.org Maven] project, mainly to manage dependencies but we preferred to keep a basic Java project not to impose a solution.

You could see this on the Package Explorer subwindow ...

=== Adding dependencies ===

Then it will be mandatory to add '''GENIUS''' library and other dependencies. To do it, you will have to:
* activate the "''Properties''" subwindow,

* then selecting the "''Java Build Path''" option,
* going to the "''Libraries''" tab
* and finally adding libraries as "''External jars''"

Your project explorer must show this:

=== Adding the Java code ===

Now, you may import the following code ...

<syntaxhighlight lang="java">
import fr.cnes.genius.exception.GException;
import fr.cnes.genius.lowLevel.GButton;
import fr.cnes.genius.lowLevel.GFrame;
import fr.cnes.genius.lowLevel.GPanel;

public class MyPanel extends GPanel {

private GButton but;

public MyPanel () {
but = new GButton("Button");
}
public void display() throws GException {
put(but);
}

public void generic() { }

public static void main(String[] args) {
MyPanel pan = new MyPanel();
GFrame frame = new GFrame("Test", pan);
frame.display();
}

};
</syntaxhighlight>

Note that the import lines must be added (or refreshed) automatically, using the Ctrl-Shift-O Eclipse shortcut.

=== Your first GUI ! ===

You will obtain this tiny frame including a button ...
