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 CursorSupport |
getCursorSupport()
Returns the
CursorSupport of this policy. |
protected Point |
getInitialMouseLocationInScene()
Returns the initial mouse location in scene coordinates.
|
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 java.util.List<IContentPart<javafx.scene.Node,? extends javafx.scene.Node>> |
getTargetParts()
Returns a
List containing all IContentPart s that should
be relocated by this policy. |
protected FXTransformPolicy |
getTransformPolicy(IContentPart<javafx.scene.Node,? extends javafx.scene.Node> part)
Returns the
FXTransformPolicy that is installed on the given
IContentPart . |
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 |
isTranslate(javafx.scene.input.MouseEvent event)
Returns whether the given
MouseEvent should trigger translation. |
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 |
setInitialMouseLocationInScene(Point point)
Sets the initial mouse location 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)
