FXBendOnSegmentDragPolicy() |
| 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()
Returns the
FXBendConnectionPolicy of the host. |
protected CursorSupport |
getCursorSupport()
Returns the
CursorSupport of this policy. |

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. |
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 |
isBend(javafx.scene.input.MouseEvent event)
Returns
true if the given MouseEvent should trigger
bending. |
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.
