Constructor Detail

QuickDiffToggleAction

public QuickDiffToggleAction()
Method Detail

setActiveEditor

public void setActiveEditor(
IAction action,
                            
IEditorPart targetEditor)
Description copied from interface: IEditorActionDelegate
Sets the active editor for the delegate. Implementors should disconnect from the old editor, connect to the new editor, and update the action to reflect the new editor.

Specified by:
setActiveEditor in interface IEditorActionDelegate
Parameters:
action - the action proxy that handles presentation portion of the action
targetEditor - the new editor target

run

public void run(
IAction action)
Description copied from interface: 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 IActionDelegate
Parameters:
action - the action proxy that handles the presentation portion of the action

selectionChanged

public void selectionChanged(
IAction action,
                             
ISelection selection)
Description copied from interface: 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 IActionDelegate
Parameters:
action - the action proxy that handles presentation portion of the action
selection - the current selection, or null if there is no selection.

update

public void update()
Description copied from interface: IUpdate
Requests that this object update itself.

Specified by:
update in interface IUpdate
