Method Detail

isWindowReady

public boolean isWindowReady(Window w)

Returns whether the window is ready to receive OS-level event input. A window's "isShowing" flag may be set true before the WINDOW_OPENED event is generated, and even after the WINDOW_OPENED is sent the window peer is not guaranteed to be ready.

Parameters:

w - the given window.

Returns:

whether the window is ready to receive OS-level event input.

eventQueueFor

public EventQueue eventQueueFor(Component c)

Returns the event queue corresponding to the given component. In most cases, this is the same as Component.getToolkit().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.

allEventQueues

public Collection<EventQueue> allEventQueues()

Returns all known event queues.

Returns:

all known event queues.

rootWindows

public 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.

instance

@RunsInEDT
public static WindowMonitor instance()

Returns the singleton instance of this class.

Returns:

the singleton instance of this class.
