public class FXBendFirstAnchorageOnSegmentHandleDragPolicy extends AbstractFXInteractionPolicy implements IFXOnDragPolicy
FXBendFirstAnchorageOnSegmentHandleDragPolicy
is an
IFXOnDragPolicy
that can be installed on the handle parts of an
Connection
, so that the user is able to manipulate that connection by
dragging its handles. This policy expects that a handle is created for each
anchor point of the connection (start, way, end), as well as for each middle
point of a segment. Moreover, this policy expects that the respective handles
are of type FXCircleSegmentHandlePart
.Constructor and Description |
---|
FXBendFirstAnchorageOnSegmentHandleDragPolicy() |
Modifier and Type | Method and Description |
---|---|
void |
drag(javafx.scene.input.MouseEvent e,
Dimension delta)
This callback method is invoked when the mouse is moved while a button is
pressed.
|
void |
dragAborted()
This callback method is invoked when the mouse drag gesture is aborted,
i.e. the gesture ends unexpectedly, without a mouse release event being
fired.
|
protected FXBendConnectionPolicy |
getBendPolicy(IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> targetPart)
Returns the
FXBendConnectionPolicy that is installed on the given
IVisualPart . |
protected CursorSupport |
getCursorSupport()
Returns the
CursorSupport of this policy. |
AbstractFXSegmentHandlePart<? extends javafx.scene.Node> |
getHost()
|
protected IVisualPart<javafx.scene.Node,? extends Connection> |
getTargetPart()
Returns the target
IVisualPart for this policy. |
void |
hideIndicationCursor()
Restores the original mouse cursor when it was previously changed by a
call to
IFXOnDragPolicy.showIndicationCursor(KeyEvent) or
IFXOnDragPolicy.showIndicationCursor(MouseEvent) . |
void |
press(javafx.scene.input.MouseEvent e)
This callback method is invoked when a mouse button is pressed on the
host, which starts a mouse drag gesture.
|
void |
release(javafx.scene.input.MouseEvent e,
Dimension delta)
This callback method is invoked when the initially pressed mouse button
is released, which ends the gesture.
|
boolean |
showIndicationCursor(javafx.scene.input.KeyEvent event)
Changes the mouse cursor depending on the given
KeyEvent to
indicate the action that is performed by this policy. |
boolean |
showIndicationCursor(javafx.scene.input.MouseEvent event)
Changes the mouse cursor depending on the given
MouseEvent to
indicate the action that is performed by this policy. |
protected void |
updateHandles()
Re-computes the handle parts.
