| 11 | <p>In order to debug composite applications using the Newton Eclipse |
| 12 | plugin, use the runtime configuration you created in above, and start it |
| 13 | using a debug session. This will launch a newton container as a separate |
| 14 | process to the Eclipse IDE environment but which can be controlled from |
| 15 | the IDE</p> |
| 16 | |

| 20 | |
| 21 | <p>Install your composite into this container using the Newton context |
| 22 | menu in the package view as documented above. In this example we have |
| 23 | installed the gui.composite component from the fractal render demo into |
| 24 | a Newton debug container.</p> |

| 28 | <img class="figure" alt="Fractal GUI Debug" src="my-images/demo-gui.png"></div> |
| 29 | |
| 30 | <p>You can now add break points within your code to allow you to get a |
| 31 | better idea of what is going on within your application. In this example |
| 32 | we have added a break point to the FractalViewFrame of the fractal |
| 33 | render demo to break out into an interactive debug session when any of |
| 34 | the buttons <em>draw</em>, <em>save</em>, <em>cancel</em> are pressed on |
| 35 | the gui window.</p> |

| 40 | |
| 41 | <p>You can then inspect variable values in top-right-hand corner as per |
| 42 | normal debugging in the Eclipse IDE.</p> |
