| Modifier and Type | Method and Description |
|---|---|
protected Angle |
computeRotationAngleCW(javafx.scene.input.MouseEvent e,
IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> part)
Computes the clock-wise rotation angle based on the initial mouse
position and the actual mouse position.
|
protected javafx.scene.ImageCursor |
createRotateCursor()
Returns the
Cursor that is shown to indicate that this policy
will perform a rotation. |
protected java.util.List<IContentPart<javafx.scene.Node,? extends javafx.scene.Node>> |
determineTargetParts()
Returns a
List containing the whole selection. |
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 javafx.scene.Cursor |
getRotateCursor()
Returns the
Cursor that indicates rotation. |
protected java.util.List<IContentPart<javafx.scene.Node,? extends javafx.scene.Node>> |
getTargetParts()
Returns the target parts of this policy.
|
protected FXTransformPolicy |
getTransformPolicy(IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> part)
Returns the
FXTransformPolicy that is installed on the given
IVisualPart. |
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 |
isRotate(javafx.scene.input.MouseEvent event)
Returns
true if the given MouseEvent should trigger
rotation. |
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 boolean |
showIndicationCursor(boolean isControlDown)
If the given flag isControlDown is
true, then the
mouse cursor is changed to a rotate cursor. |
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. |
