Examples of org.eclipse.jface.preference.IPreferenceStore.addPropertyChangeListener()

org.eclipse.jface.preference.IPreferenceStore.addPropertyChangeListener()

Adds a property change listener to this preference store.

Note The types of the oldValue and newValue of the generated PropertyChangeEvent are determined by whether or not the typed API in IPreferenceStore was called. If values are changed via setValue(name,type) the values in the PropertyChangedEvent will be of that type. If they are set using a non typed API (i.e. #setToDefault or using the OSGI Preferences) the values will be unconverted Strings.

A listener will be called in the same Thread that it is invoked in. Any Thread dependant listeners (such as those who update an SWT widget) will need to update in the correct Thread. In the case of an SWT update you can update using Display#syncExec(Runnable) or Display#asyncExec(Runnable).

Likewise any application that updates an IPreferenceStore from a Thread other than the UI Thread should be aware of any listeners that require an update in the UI Thread.
