public abstract class PopupWindow
extends Window

PopupWindow is the parent for a variety of different types of popup based windows including Popup and Tooltip and ContextMenu.

A PopupWindow is a secondary window which has no window decorations or title bar. It doesn't show up in the OS as a top-level window. It is typically used for tool tip like notification, drop down boxes, menus, and so forth.

The PopupWindow cannot be shown without an owner. PopupWindows require that an owner window exist in order to be shown. However, it is possible to create a PopupWindow ahead of time and simply set the owner (or change the owner) before first being made visible. Attempting to change the owner while the PopupWindow is visible will result in an IllegalStateException.

The PopupWindow encapsulates much of the behavior and functionality common to popups, such as the ability to close when the "esc" key is pressed, or the ability to hide all child popup windows whenever this window is hidden. These abilities can be enabled or disabled via properties.

Property Details

ownerWindow

public final ReadOnlyObjectProperty<Window> ownerWindowProperty

The window which is the parent of this popup. All popups must have an owner window.

See Also:

getOwnerWindow()

ownerNode

public final ReadOnlyObjectProperty<Node> ownerNodeProperty

The node which is the owner of this popup. All popups must have an owner window but are not required to be associated with an owner node. If an autohide Popup has an owner node, mouse press inside the owner node doesn't cause the Popup to hide.

See Also:

getOwnerNode()

autoFix

public final BooleanProperty autoFixProperty

This convenience variable indicates whether, when the popup is shown, it should automatically correct its position such that it doesn't end up positioned off the screen.

Default value:

true

See Also:

isAutoFix(), setAutoFix(boolean)

autoHide

public final BooleanProperty autoHideProperty

Specifies whether Popups should auto hide. If a popup loses focus and autoHide is true, then the popup will be hidden automatically.

The only exception is when owner Node is specified using show(javafx.scene.Node, double, double). Focusing owner Node will not hide the PopupWindow.

Default value:

false

See Also:

isAutoHide(), setAutoHide(boolean)

onAutoHide

public final ObjectProperty<EventHandler<Event>> onAutoHideProperty

Called after autoHide is run.

See Also:

getOnAutoHide(), setOnAutoHide(EventHandler)

hideOnEscape

public final BooleanProperty hideOnEscapeProperty

Specifies whether the PopupWindow should be hidden when an unhandled escape key is pressed while the popup has focus.

Default value:

true

See Also:

isHideOnEscape(), setHideOnEscape(boolean)

consumeAutoHidingEvents

public final BooleanProperty consumeAutoHidingEventsProperty

Specifies whether the event, which caused the Popup to hide, should be consumed. Having the event consumed prevents it from triggering some additional UI response in the Popup's owner window.

Default value:

true

Since:

JavaFX 2.2

See Also:

getConsumeAutoHidingEvents(), setConsumeAutoHidingEvents(boolean)

anchorX

public final ReadOnlyDoubleProperty anchorXProperty

Since:

JavaFX 8.0

See Also:

getAnchorX(), setAnchorX(double)

anchorY

public final ReadOnlyDoubleProperty anchorYProperty

Specifies the y coordinate of the popup anchor point on the screen. If the anchorLocation is set to WINDOW_TOP_LEFT or WINDOW_TOP_RIGHT the y and anchorY values will be identical.

Since:

JavaFX 8.0

See Also:

getAnchorY(), setAnchorY(double)

anchorLocation

public final ObjectProperty<PopupWindow.AnchorLocation> anchorLocationProperty

Specifies the popup anchor point which is used in popup positioning. The point can be set to a corner of the popup window or a corner of its content. In this context the content corners are derived from the popup root node's layout bounds.

In general changing of the anchor location won't change the current window position. Instead of that, the anchorX and anchorY values are recalculated to correspond to the new anchor point.
