Dans cette leçon, vous activez EGL et un projet EGL pour contenir vos fichiers source EGL.
All code, files, and artifacts in the workbench must be associated
with a project. A project works like a top-level folder to hold your files.
In this case, you will need an EGL project for your EGL application.
- In the workbench, click . The Preferences
window opens.
- In the left pane of the Preferences window, click .
- In the list of capabilities in the right pane, select the EGL
Developer check box. Enabling this capability
tells the workbench that you will be working with EGL. You may have many other
capabilities in the list, but for now the EGL Developer capability
is the only one that matters.
- Click OK.
- Click . The New Project
window opens.
- In the New Project window, expand EGL and
click EGL Project.
- Click Next.
- In the New EGL Project wizard, assign a Project name such
as Hello.
- Click General Project. The other
types of EGL project enable particular types of user interfaces, but since
you don't need a dedicated user interface for this project, the general EGL
project is appropriate. The first window of the New EGL
Project wizard looks like this:
- Fill in the project name, and then, click Next.
- Under Target Runtime Platform, click Java. You can generate EGL code either to Java or to COBOL. You will use Java for
this tutorial because the workbench can run Java code directly.
- Make sure that Create a new build descriptor is
selected. Build descriptors contain options for generating your
program into another language. You do not need to worry about them at this
point because the wizard will create an appropriate build descriptor for you. The second window of the New EGL Project wizard looks like this:
- Click Finish.
- You may see a message window that asks, "This kind of project is
usually associated with the EGL Perspective. Do you want to switch to this
perspective now?" If you see this window, click Yes. The different workbench perspectives display editors, information windows,
and tools appropriate to specific tasks. The Project
Explorer view in the upper left of the default workbench displays
a new folder called Hello. This is your new EGL project.
- Expand the Hello project by clicking the plus sign next to it and
note the folders and files that EGL automatically created for you.
The EGLSource folder will
contain your EGL code. Right now, it contains an EGL build file named Hello.eglbld,
which contains an EGL Build Descriptor part. By default, the EGLSource folder
contains an EGL deployment descriptor file named Hello.EGLDD. The deployment
descriptor file contains information on deploying your project as a web service
and information on web services in other applications that your project will
use. Since your project will not contain or use any services, you can ignore
this file for now.
Now you have an EGL project. In the next lesson, you will create an
EGL program in this project.
