Examples of org.eclipse.ui.plugin.AbstractUIPlugin

org.eclipse.ui.plugin.AbstractUIPlugin
Abstract base class for plug-ins that integrate with the Eclipse platform UI.
Subclasses obtain the following capabilities:

Preferences
- The platform core runtime contains general support for plug-in preferences (org.eclipse.core.runtime.Preferences). This class provides appropriate conversion to the older JFace preference API (org.eclipse.jface.preference.IPreferenceStore).
- The method getPreferenceStore returns the JFace preference store (cf. Plugin.getPluginPreferences which returns a core runtime preferences object.
- Subclasses may reimplement initializeDefaultPreferences to set up any default values for preferences using JFace API. In this case, initializeDefaultPluginPreferences should not be overridden.
- Subclasses may reimplement initializeDefaultPluginPreferences to set up any default values for preferences using core runtime API. In this case, initializeDefaultPreferences should not be overridden.
- Preferences are also saved automatically on plug-in shutdown. However, saving preferences immediately after changing them is strongly recommended, since that ensures that preference settings are not lost even in the event of a platform crash.
Dialogs
- The dialog store is read the first time getDialogSettings is called.
- The dialog store allows the plug-in to "record" important choices made by the user in a wizard or dialog, so that the next time the wizard/dialog is used the widgets can be defaulted to better values. A wizard could also use it to record the last 5 values a user entered into an editable combo - to show "recent values".
- The dialog store is found in the file whose name is given by the constant FN_DIALOG_STORE. A dialog store file is first looked for in the plug-in's read/write state area; if not found there, the plug-in's install directory is checked. This allows a plug-in to ship with a read-only copy of a dialog store file containing initial values for certain settings.
- Plug-in code can call saveDialogSettings to cause settings to be saved in the plug-in's read/write state area. A plug-in may opt to do this each time a wizard or dialog is closed to ensure the latest information is always safe on disk.
- Dialog settings are also saved automatically on plug-in shutdown.
Images
- A typical UI plug-in will have some images that are used very frequently and so need to be cached and shared. The plug-in's image registry provides a central place for a plug-in to store its common images. Images managed by the registry are created lazily as needed, and will be automatically disposed of when the plug-in shuts down. Note that the number of registry images should be kept to a minimum since many OSs have severe limits on the number of images that can be in memory at once.
For easy access to your plug-in object, use the singleton pattern. Declare a static variable in your plug-in class for the singleton. Store the first (and only) instance of the plug-in class in the singleton when it is created. Then access the singleton when needed through a static getDefault method.
