Class MenuDragMouseEvent

  • All Implemented Interfaces:
    Serializable 

    public class MenuDragMouseEvent
extends MouseEvent
    MenuDragMouseEvent is used to notify interested parties that the menu element has received a MouseEvent forwarded to it under drag conditions.

    Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

      • MenuDragMouseEvent

        public MenuDragMouseEvent(Component source,
                          int id,
                          long when,
                          int modifiers,
                          int x,
                          int y,
                          int clickCount,
                          boolean popupTrigger,
                          MenuElement[] p,
                          MenuSelectionManager m)
        Constructs a MenuDragMouseEvent object.

        Absolute coordinates xAbs and yAbs are set to source's location on screen plus relative coordinates x and y. xAbs and yAbs are set to zero if the source is not showing.

        Parameters:
        source - the Component that originated the event (typically this)
        id - an int specifying the type of event, as defined in MouseEvent
        when - a long identifying the time the event occurred
        modifiers - an int specifying any modifier keys held down, as specified in InputEvent
        x - an int specifying the horizontal position at which the event occurred, in pixels
        y - an int specifying the vertical position at which the event occurred, in pixels
        clickCount - an int specifying the number of mouse-clicks
        popupTrigger - a boolean -- true if the event {should?/did?} trigger a popup
        p - an array of MenuElement objects specifying a path to a menu item affected by the drag
        m - a MenuSelectionManager object that handles selections

        MouseEvent.MouseEvent(java.awt.Component, int, long, int, int, int, int, int, int, boolean, int)

        public MenuDragMouseEvent(Component source,
                          int id,
                          long when,
                          int modifiers,
                          int x,
                          int y,
                          int xAbs,
                          int yAbs,
                          int clickCount,
                          boolean popupTrigger,
                          MenuElement[] p,
                          MenuSelectionManager m)
        Constructs a MenuDragMouseEvent object.

        Even if inconsistent values for relative and absolute coordinates are passed to the constructor, the MenuDragMouseEvent instance is still created.

        Parameters:
        source - the Component that originated the event (typically this)
        id - an int specifying the type of event, as defined in MouseEvent
        when - a long identifying the time the event occurred
        modifiers - an int specifying any modifier keys held down, as specified in InputEvent
        x - an int specifying the horizontal position at which the event occurred, in pixels
        y - an int specifying the vertical position at which the event occurred, in pixels
        xAbs - an int specifying the horizontal absolute position at which the event occurred, in pixels
        yAbs - an int specifying the vertical absolute position at which the event occurred, in pixels
        clickCount - an int specifying the number of mouse-clicks
        popupTrigger - a boolean -- true if the event {should?/did?} trigger a popup
        p - an array of MenuElement objects specifying a path to a menu item affected by the drag
        m - a MenuSelectionManager object that handles selections
