                      extended by 

org.eclipse.ui.actions.WorkspaceAction
                          extended by 
org.eclipse.ui.actions.OpenResourceAction
All Implemented Interfaces:
EventListener, IResourceChangeListener, IAction, ISelectionChangedListener

public class OpenResourceAction

Standard action for opening the currently selected project(s).

Note that there is a different action for opening an editor on file resources: OpenFileAction.

This class may be instantiated; it is not intended to be subclassed.

Restriction:
This class is not intended to be subclassed by clients.

Constructor Detail

OpenResourceAction

public OpenResourceAction(
Shell shell)
Deprecated.  OpenResourceAction(IShellProvider)

Creates a new action.

Parameters:
shell - the shell for any dialogs

OpenResourceAction

public OpenResourceAction(
IShellProvider provider)
Creates a new action.

Parameters:
provider - the shell for any dialogs
Since:
3.4
Method Detail

getOperationMessage

protected 
String getOperationMessage()
Description copied from class: WorkspaceAction
Returns the string to display for this action's operation.

Note that this hook method is invoked in a non-UI thread.

Subclasses must implement this method.

Specified by:
getOperationMessage in class WorkspaceAction
Returns:
the message

getProblemsMessage

protected 
String getProblemsMessage()
Description copied from class: WorkspaceAction
Returns the string to display for this action's problems dialog.

The WorkspaceAction implementation of this method returns a vague message (localized counterpart of something like "The following problems occurred."). Subclasses may reimplement to provide something more suited to the particular action.

Overrides:
getProblemsMessage in class WorkspaceAction
Returns:
the problems message

getProblemsTitle

protected 
String getProblemsTitle()
Description copied from class: WorkspaceAction
Returns the title for this action's problems dialog.

The WorkspaceAction implementation of this method returns a generic title (localized counterpart of "Problems"). Subclasses may reimplement to provide something more suited to the particular action.

Overrides:
getProblemsTitle in class WorkspaceAction
Returns:
the problems dialog title

invokeOperation

protected void invokeOperation(
IResource resource,
                               
IProgressMonitor monitor)
                        throws 
CoreException
Description copied from class: WorkspaceAction
Performs this action's operation on each of the selected resources, reporting progress to, and fielding cancel requests from, the given progress monitor.

Note that this method is invoked in a non-UI thread.

Subclasses must implement this method.

Overrides:
invokeOperation in class WorkspaceAction
Parameters:
resource - one of the selected resources
monitor - a progress monitor
Throws:
CoreException - if the operation fails

resourceChanged

public void resourceChanged(
IResourceChangeEvent event)
Handles a resource changed event by updating the enablement if one of the selected projects is opened or closed.

Specified by:
resourceChanged in interface IResourceChangeListener
Parameters:
event - the resource change event
See Also:
IResourceDelta

run

public void run()
Description copied from class: WorkspaceAction
The CoreWrapperAction implementation of this IAction method uses a ProgressMonitorDialog to run the operation. The operation calls execute (which, in turn, calls invokeOperation). Afterwards, any CoreExceptions encountered while running the operation are reported to the user via a problems dialog.

Subclasses may extend this method.

Specified by:
run in interface IAction
Overrides:
run in class WorkspaceAction

shouldPerformResourcePruning

protected boolean shouldPerformResourcePruning()
Description copied from class: WorkspaceAction
Returns whether this action should attempt to optimize the resources being operated on. This kind of pruning makes sense when the operation has depth infinity semantics (when the operation is applied explicitly to a resource then it is also applied implicitly to all the resource's descendents).

The WorkspaceAction implementation of this method returns true. Subclasses should reimplement to return false if pruning is not required.

Overrides:
shouldPerformResourcePruning in class WorkspaceAction
Returns:
true if pruning should be performed, and false if pruning is not desired

updateSelection

protected boolean updateSelection(
IStructuredSelection s)
The OpenResourceAction implementation of this SelectionListenerAction method ensures that this action is enabled only if one of the selections is a closed project.

Overrides:
updateSelection in class WorkspaceAction
Parameters:
s - the new selection
Returns:
true if the action should be enabled for this selection, and false otherwise
