Class UMLChangeDispatch

java.lang.Object
  org.argouml.uml.ui.UMLChangeDispatch

All Implemented Interfaces:

EventListener, ru.novosoft.uml.MElementListener, Runnable, UMLUserInterfaceComponent

public class UMLChangeDispatch

extends Object

implements Runnable, UMLUserInterfaceComponent

This class is used to dispatch a NSUML change event (which may occur on a non-UI) thread) to user interface components. The class is created in response to a NSUML change event being captures by a UMLUserInterfaceContainer and then is passed as an argument to InvokeLater to be run on the user interface thread.

This class is updated to cope with changes to the targetchanged mechanism.

Constructor Detail

UMLChangeDispatch

public UMLChangeDispatch(Container uic,
                         int et)

Creates a UMLChangeDispatch. eventType is overriden if a call to one of the event functions is called.

Parameters:

uic - user interface container to which changes are dispatched.

et - -1 will add event listener to new target, 0 for default.

Method Detail

targetChanged

public void targetChanged()

Configures this instance to dispatch a targetChanged event.

Specified by:

targetChanged in interface UMLUserInterfaceComponent

targetReasserted

public void targetReasserted()

Description copied from interface: UMLUserInterfaceComponent

This method is called when the navigation history has been changed (and navigation buttons may need to be updated). targetChanged implies navigationHistoryChanged, so this method will not be called after a targetChange.

Specified by:

targetReasserted in interface UMLUserInterfaceComponent

See Also:

UMLUserInterfaceComponent.targetReasserted()

propertySet

public void propertySet(ru.novosoft.uml.MElementEvent mee)

Configures this instance to dispatch a propertySet event.

Specified by:

propertySet in interface ru.novosoft.uml.MElementListener

Parameters:

mee - NSUML event

listRoleItemSet

public void listRoleItemSet(ru.novosoft.uml.MElementEvent mee)

Configures this instance to dispatch a listRoleItemSet event.

Specified by:

listRoleItemSet in interface ru.novosoft.uml.MElementListener

Parameters:

mee - NSUML event

recovered

public void recovered(ru.novosoft.uml.MElementEvent mee)

Configures this instance to dispatch a recovered event.

Specified by:

recovered in interface ru.novosoft.uml.MElementListener

Parameters:

mee - NSUML event.

removed

public void removed(ru.novosoft.uml.MElementEvent mee)

Configures this instance to dispatch a removed event.

Specified by:

removed in interface ru.novosoft.uml.MElementListener

Parameters:

mee - NSUML event.

roleAdded

public void roleAdded(ru.novosoft.uml.MElementEvent mee)

Configures this instance to dispatch a roleAdded event.

Specified by:

roleAdded in interface ru.novosoft.uml.MElementListener

Parameters:

mee - NSUML event.

roleRemoved

public void roleRemoved(ru.novosoft.uml.MElementEvent mee)

Configures this instance to dispatch a roleRemoved event.

Specified by:

roleRemoved in interface ru.novosoft.uml.MElementListener

Parameters:

mee - NSUML event

run

public void run()

Called by InvokeLater on user interface thread. Dispatches event to all contained objects implementing UMLUserInterfaceComponent. If event == -1, adds change listener to new target on completion of dispatch.

Specified by:

run in interface Runnable

dispatch

private void dispatch(Container theAWTContainer)

Iterates through all children of this container. If a child is another container then calls dispatch iteratively, if a child supports UMLUserInterfaceComponent then calls the appropriate method.

Parameters:

theAWTContainer - AWT container

synchronizedDispatch

private void synchronizedDispatch(Container cont)
