DockDropZone

public DockDropZone(DockElement target,
 DockPosition position,
 DockDropZoneType type,
 javafx.geometry.Bounds bounds,
 int depth,
 Integer tabIndex,
 Double insertLineX)

Creates one resolved drop-zone candidate.

Parameters:

target - drop target element

position - proposed dock position on the target

type - drop-zone type

bounds - scene-space zone bounds

depth - target depth in the layout tree

tabIndex - target tab index for tab operations, or null

insertLineX - scene x-position for tab insert indicator, or null

Method Details

getTarget

public DockElement getTarget()

Returns the target element this zone docks into.

Returns:

target element

getPosition

public DockPosition getPosition()

Returns the resolved dock position for this zone.

Returns:

drop position

getType

public DockDropZoneType getType()

Returns the semantic drop-zone type.

Returns:

zone type

getBounds

public javafx.geometry.Bounds getBounds()

Returns the scene-space bounds used for hit testing.

Returns:

zone bounds, or null

getDepth

public int getDepth()

Returns the target depth in the layout tree.

Returns:

depth (higher is deeper)

getTabIndex

public Integer getTabIndex()

Returns the tab index used for tab-header drops.

Returns:

tab index or null

getInsertLineX

public Double getInsertLineX()

Returns the tab insert-line x-coordinate in scene space.

Returns:

scene x-coordinate or null

contains

public boolean contains(double sceneX,
 double sceneY)

Tests whether a scene-space point is inside this zone.

Parameters:

sceneX - scene x-coordinate

sceneY - scene y-coordinate

Returns:

true when the point is inside the zone bounds

area

public double area()

Returns the area of this zone in square pixels.

Returns:

zone area, or 0.0 when bounds are unavailable
