public class FXResizeTranslateFirstAnchorageOnHandleDragPolicy extends AbstractFXInteractionPolicy implements IFXOnDragPolicy
FXResizeTranslateFirstAnchorageOnHandleDragPolicy is an
IFXOnDragPolicy that handles the resize and relocation of its
(selected) first anchorage when an AbstractFXSegmentHandlePart of the
box selection of the first anchorage is dragged with the mouse.adaptableadaptableIAdaptable.Bound.Impl<T extends IAdaptable>| Constructor and Description |

| Modifier and Type | Method and Description |
|---|---|
protected IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> |
determineTargetPart()
Returns the target
IVisualPart for this policy. |
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 CursorSupport |
getCursorSupport()
Returns the
CursorSupport of this policy. |
AbstractFXSegmentHandlePart<? extends javafx.scene.Node> |
getHost()
|
protected FXResizePolicy |
getResizePolicy()
Returns the
FXResizePolicy that is installed on the
getTargetPart(). |
protected double |
getSnapToGridGranularityX()
Returns the horizontal granularity for "snap-to-grid" where
1 means it will snap to integer grid positions. |
protected double |
getSnapToGridGranularityY()
Returns the vertical granularity for "snap-to-grid" where
1
means it will snap to integer grid positions. |
protected IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> |
getTargetPart()
Returns the target part of this policy.
|
protected FXTransformPolicy |
getTransformPolicy()
Returns the
FXTransformPolicy that is installed on the
getTargetPart(). |
void |
hideIndicationCursor()
Restores the original mouse cursor when it was previously changed by a
call to
IFXOnDragPolicy.showIndicationCursor(KeyEvent) or
IFXOnDragPolicy.showIndicationCursor(MouseEvent). |
protected boolean |
isResizeTranslate(javafx.scene.input.MouseEvent event)
Returns
true if the given MouseEvent should trigger
resize and translate. |
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.
|
protected void |
setTargetPart(IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> determinedTargetPart)
Sets the target part (i.e. the part that is resized and translated) of
this policy to the given value.
|
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. |
