public class FXMarqueeOnDragPolicy extends AbstractFXInteractionPolicy implements IFXOnDragPolicy
FXMarqueeOnDragPolicy
is an IFXOnDragPolicy
that performs
marquee selection when the mouse is dragged. The start and end position of
the mouse span a marquee area. Everything within that area will be selected.adaptable

protected void |
addFeedback()
Adds a feedback rectangle to the root part of the
host
. |
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.
|
static java.util.List<javafx.scene.Node> |
findContainedNodes(javafx.scene.Node root,
double x0,
double y0,
double x1,
double y1)
Returns a
List of all Node s that are descendants of the
given root Node and fully contained within the bounds specified
by [x0, y0, x1, y1] . |
protected CursorSupport |
getCursorSupport()
Returns the
CursorSupport of this policy. |
protected java.util.List<IContentPart<javafx.scene.Node,? extends javafx.scene.Node>> |
getParts(java.util.List<javafx.scene.Node> nodes)
|
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.
|
protected void |
removeFeedback()
Removes the feedback rectangle.
|
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 |
