Method Detail

checkObjectType

public boolean checkObjectType(Object obj)

Override of parent. Called when testing if action should be enabled base on current selection. We check the selected object is one of our subsystems, and if we are currently connected.

Overrides:

checkObjectType in class SystemBaseAction

run

public void run()

Called when this action is selection from the popup menu.

Specified by:

run in interface IAction

Overrides:

run in class SystemBaseAction

See Also:

Action.run()

updateSelection

public boolean updateSelection(IStructuredSelection selection)

Description copied from class: SystemBaseAction

First opportunity to decide if the action should be enabled or not based on the current selection. Called by default implementation of selectionChanged, which converts the ISelection to an IStructuredSelection, which is all we support. The return result is used to enable or disable this action.

The default implementation of this method:

• Returns false if calling checkObjectType on any object in the selection list returns false.
• Returns true otherwise.

If desired, override this method for a different algorithm to decide enablement.

Overrides:

updateSelection in class SystemBaseAction
