Method Detail

drag

public void drag(javafx.scene.input.MouseEvent e,
                 Dimension delta)

Description copied from class: AbstractFXOnDragPolicy

This callback method is invoked when the mouse is moved while a button is pressed.

Specified by:

drag in class AbstractFXOnDragPolicy

Parameters:

e - The original MouseEvent.

delta - The mouse offset since AbstractFXOnDragPolicy.press(MouseEvent) (in pixel).

getHost

public AbstractFXSegmentHandlePart<? extends javafx.scene.Node> getHost()

Description copied from interface: IPolicy

Returns the host of this IPolicy, i.e. the IVisualPart this IPolicy is attached to.

Specified by:

getHost in interface IPolicy<javafx.scene.Node>

Overrides:

getHost in class AbstractPolicy<javafx.scene.Node>

Returns:

The host of this IPolicy.

getResizeRelocatePolicy

protected FXResizeRelocatePolicy getResizeRelocatePolicy()

Returns the FXResizeRelocatePolicy that is installed on the getTargetPart().

Returns:

The FXResizeRelocatePolicy that is installed on the getTargetPart().

getTargetPart

protected IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> getTargetPart()

Returns the target IVisualPart for this policy. Per default the first anchorage is returned.

Returns:

The target IVisualPart for this policy.

press

public void press(javafx.scene.input.MouseEvent e)

Description copied from class: AbstractFXOnDragPolicy

This callback method is invoked when a mouse button is pressed on the host.

Specified by:

press in class AbstractFXOnDragPolicy

Parameters:

e - The original MouseEvent

release

public void release(javafx.scene.input.MouseEvent e,
                    Dimension delta)

Description copied from class: AbstractFXOnDragPolicy

This callback method is invoked when the previously pressed mouse button is released.

Specified by:

release in class AbstractFXOnDragPolicy

Parameters:

e - The original MouseEvent.

delta - The mouse offset since AbstractFXOnDragPolicy.press(MouseEvent) (in pixel).

updateDeltas

protected void updateDeltas(javafx.scene.input.MouseEvent e)

Computes the resize and relocation deltas from the given MouseEvent. The AbstractFXSegmentHandlePart.getSegmentIndex() of the host determines the logical position of the handle:

• 0: top left
• 1: top right
• 2: bottom right
• 3: bottom left

Parameters:

e - The drag MouseEvent.
