| Before a plugin is being deactivated, it has a chance of running some codes to |
| save its state and more importantly doing some cleanup! In order to help you doing |
| the cleanup, here is checklist that can help you. |
| <ul> |
| <!-- UI --> |
| <li>Did you deallocate all the graphics you allocated: fonts, images, colors</li> |
| <!-- RUNTIME --> |
| <li>Did you unregister the IAdapterFactory you created? See IAdapterManager.unregisterAdapters.</li> |
| <!-- RESOURCES --> |
| <li>Did you unregister the IResourceChangeListener you created? See IWorkspace.removeResourceChangeListener.</li> |
| <li>Beside the instances created through createExecutableExtension(), who should |
| collect the other instances?</li> |
| <li>As a matter of example, which plugin is supposed to close the views: the |
| UI plugin, or the plugin providing the view?</li> |
| <li>Does a generic scheme to collect the instance exists?</li> |
| <li>When can a brute force cleanup mechanism be applied?</li> |
| </ul> |
