public ToggleXtextNatureAction()

Method Detail

run

public void run(org.eclipse.jface.action.IAction action)

Description copied from interface: org.eclipse.ui.IActionDelegate

Performs this action.

This method is called by the proxy action when the action has been triggered. Implement this method to do the actual work.

Note: If the action delegate also implements IActionDelegate2, then this method is not invoked but instead the runWithEvent(IAction, Event) method is called.

Specified by:

run in interface org.eclipse.ui.IActionDelegate

Parameters:

action - the action proxy that handles the presentation portion of the action

selectionChanged

public void selectionChanged(org.eclipse.jface.action.IAction action,
                             org.eclipse.jface.viewers.ISelection selection)

Description copied from interface: org.eclipse.ui.IActionDelegate

Notifies this action delegate that the selection in the workbench has changed.

Implementers can use this opportunity to change the availability of the action or to modify other presentation properties.

When the selection changes, the action enablement state is updated based on the criteria specified in the plugin.xml file. Then the delegate is notified of the selection change regardless of whether the enablement criteria in the plugin.xml file is met.

Specified by:

selectionChanged in interface org.eclipse.ui.IActionDelegate

Parameters:

action - the action proxy that handles presentation portion of the action

selection - the current selection, or null if there is no selection.

setActivePart

public void setActivePart(org.eclipse.jface.action.IAction action,
                          org.eclipse.ui.IWorkbenchPart targetPart)

Description copied from interface: org.eclipse.ui.IObjectActionDelegate

Sets the active part for the delegate. The active part is commonly used to get a working context for the action, such as the shell for any dialog which is needed.

This method will be called every time the action appears in a popup menu. The targetPart may change with each invocation.

Specified by:

setActivePart in interface org.eclipse.ui.IObjectActionDelegate

Parameters:

action - the action proxy that handles presentation portion of the action; must not be null.

targetPart - the new part target; must not be null.
