Ensemble Graphics Toolkit: Resources

Introduction

In this training, you will learn how to add a *.png image to your application.

Steps:

  • Resources

Prerequisites

You have prepared the Host PC with all the development software tools and Ensemble Graphics Toolkit source code as explained in:

You have installed and prepared the Eclipse IDE for C/C++ Developers as explained in:

You have performed the exercises in:


AnimationSequence Class

In this section, you will modify the timer.cpp source code that you entered in the Ensemble Graphics Toolkit: Animation Part 1 training to construct an animation sequence.

In this training, you will use EgtProject and its settings you entered in the training: Ensemble Graphics Toolkit: Animation Part 1.

1

Modify the event.cpp source code by adding the following lines of code as shown below:

2

Save your program by selecting File > Save. You may also save by pressing CTRL + S.

3

To build the project, hover over EgtProject, right-click, and select Build Project from the menu, or you can click on the Build icon.

The Console window (bottom pane) will display the build progress.

4

Click on the Run button.

5

Observe the WVGA Display on the target:

The timer.cpp executable is running remotely on the target.

Observe the label Ensemble Graphics Toolkit at the top of the WVGA Display move (animate) along the animation sequence entered in the source code above.

AnimationSequence class

From ~/egt/docs/html/annotated.html, click on the AnimationSequence class. All the functions, attributes and, constructor associated with the class are documented here.

The AnimationSequence class allows user to add and manage a series of animation objects and run them as single animation. It also allows user to add one sequence into another to create complex animations.

AnimationDelay class

From ~/egt/docs/html/annotated.html, click on the AnimationDelay class. All the functions, attributes, and constructor associated with the class are documented here.

The AnimationDelay class allows user to insert simple delays into an animation sequence.

6

To stop the program, press the Stop button (upper left hand, just below the menu bar).

Before you start another session, be sure to stop the current session.


Summary

In this training, you learned how to construct an AnimationSequence class and use AnimationDelay class to create an animation sequence.
