Method Details

rootWindows

Collection<Window> rootWindows()

Return all available root windows. A root window is one that has a null parent. Nominally this means a list similar to that returned by Frame.getFrames(), but in the case of an Applet may return a few dialogs as well.

Returns:

all available root windows.

storedQueueFor

EventQueue storedQueueFor(Component c)

removeContextFor

void removeContextFor(Component component)

addContextFor

void addContextFor(Component component)

eventQueueFor

@RunsInEDT
EventQueue eventQueueFor(Component c)

Return the event queue corresponding to the given component. In most cases, this is the same as Toolkit.getSystemEventQueue(), but in the case of applets will bypass the AppContext and provide the real event queue.

Parameters:

c - the given component.

Returns:

the event queue corresponding to the given component

topParentOf

@RunsInEDT
private static Component topParentOf(Component c)

allEventQueues

Collection<EventQueue> allEventQueues()

Returns all known event queues.

Returns:

all known event queues.
