Field Detail

ATTR_REFRESH_RECURSIVE

public static final String ATTR_REFRESH_RECURSIVE

Boolean attribute indicating if a refresh scope is recursive. Default value is false.

ATTR_REFRESH_SCOPE

public static final String ATTR_REFRESH_SCOPE

String attribute identifying the scope of resources that should be refreshed after an external tool is run. The value is either a refresh variable or the default value, null, indicating no refresh.

public RefreshTab()

Method Detail

createControl

public void createControl(Composite parent)

Description copied from interface: ILaunchConfigurationTab

Creates the top level control for this launch configuration tab under the given parent composite. This method is called once on tab creation, after setLaunchConfigurationDialog is called.

Implementors are responsible for ensuring that the created control can be accessed via getControl

Parameters:

parent - the parent composite

See Also:

ILaunchConfigurationTab.createControl(org.eclipse.swt.widgets.Composite)

setDefaults

public void setDefaults(ILaunchConfigurationWorkingCopy configuration)

Description copied from interface: ILaunchConfigurationTab

Initializes the given launch configuration with default values for this tab. This method is called when a new launch configuration is created such that the configuration can be initialized with meaningful values. This method may be called before this tab's control is created.

Parameters:

configuration - launch configuration

See Also:

ILaunchConfigurationTab.setDefaults(org.eclipse.debug.core.ILaunchConfigurationWorkingCopy)

initializeFrom

public void initializeFrom(ILaunchConfiguration configuration)

Description copied from interface: ILaunchConfigurationTab

Initializes this tab's controls with values from the given launch configuration. This method is called when a configuration is selected to view or edit, after this tab's control has been created.

Parameters:

configuration - launch configuration

See Also:

ILaunchConfigurationTab.initializeFrom(org.eclipse.debug.core.ILaunchConfiguration)

performApply

public void performApply(ILaunchConfigurationWorkingCopy configuration)

Description copied from interface: ILaunchConfigurationTab

Copies values from this tab into the given launch configuration.

Parameters:

configuration - launch configuration

See Also:

ILaunchConfigurationTab.performApply(org.eclipse.debug.core.ILaunchConfigurationWorkingCopy)

getName

public String getName()

Description copied from interface: ILaunchConfigurationTab

Returns the name of this tab.

Returns:

the name of this tab

See Also:

ILaunchConfigurationTab.getName()

getImage

public Image getImage()

Description copied from interface: ILaunchConfigurationTab

Returns the image for this tab, or null if none

Specified by:

getImage in interface ILaunchConfigurationTab

Overrides:

getImage in class AbstractLaunchConfigurationTab

See Also:

ILaunchConfigurationTab.getImage()

isValid

public boolean isValid(ILaunchConfiguration launchConfig)

Description copied from interface: ILaunchConfigurationTab

Returns whether this tab is in a valid state in the context of the specified launch configuration.

This information is typically used by the launch configuration dialog to decide when it is okay to launch.

Specified by:

isValid in interface ILaunchConfigurationTab

Overrides:

isValid in class AbstractLaunchConfigurationTab

See Also:

ILaunchConfigurationTab.isValid(ILaunchConfiguration)

refreshResources

public static void refreshResources(ILaunchConfiguration configuration,
                                    IProgressMonitor monitor)
                             throws CoreException

Refreshes the resources as specified by the given launch configuration.

Parameters:

configuration - launch configuration

monitor - progress monitor which may be null

Throws:

CoreException - if an exception occurs while refreshing resources

getRefreshResources

public static IResource[] getRefreshResources(String scope)
                                       throws CoreException

activated

public void activated(ILaunchConfigurationWorkingCopy workingCopy)

Description copied from class: AbstractLaunchConfigurationTab

This method was added to the ILaunchConfigurationTab interface in the 3.0 release to allow tabs to distinguish between a tab being activated and a tab group be initialized for the first time, from a selected launch configuration. To maintain backwards compatible behavior, the default implementation provided, calls this tab's initializeFrom method. Tabs should override this method as required.

The launch tab framework was originially designed to take care of inter tab communication by applying attributes from the active tab to the launch configuration being edited, when a tab is exited, and by initializing a tab when activated. The addition of the methods activated and deactivated allow tabs to determine the appropriate course of action.

Specified by:

activated in interface ILaunchConfigurationTab

Overrides:

activated in class AbstractLaunchConfigurationTab

See Also:

ILaunchConfigurationTab.activated(org.eclipse.debug.core.ILaunchConfigurationWorkingCopy)

deactivated

public void deactivated(ILaunchConfigurationWorkingCopy workingCopy)

Description copied from class: AbstractLaunchConfigurationTab

This method was added to the ILaunchConfigurationTab interface in the 3.0 release to allow tabs to distinguish between a tab being deactivated and saving its attributes to a launch configuration. To maintain backwards compatible behavior, the default implementation provided, calls this tab's performApply method. Tabs should override this method as required.
