  • All Implemented Interfaces:
    ILayerDrawer, ILayerMouseListener
    public class LayerMultiObjectGridDrawer
extends java.lang.Object
implements ILayerDrawer
    It is able to draw objects contained by a MultiObjGrid on a LayeredSurfaceFrame.

    • Method Detail

      • isDisplayed

        public boolean isDisplayed()
        Return if the layer is currently displayed on the LayeredSurfaceFrame.
        Specified by:
        isDisplayed in interface ILayerDrawer
        Returns:
        True if it is currently painted, false otherwise.

      • setDisplay

        public void setDisplay​(boolean display)
        Decide if layer has to be painted or not.
        Specified by:
        setDisplay in interface ILayerDrawer
        Parameters:
        display - True if you want the layer to be painted, false otherwise.

      • getDescription

        public java.lang.String getDescription()
        Return the name of the layer.
        Specified by:
        getDescription in interface ILayerDrawer
        Returns:
        The name passed to the constructor.

      • paint

        public void paint​(java.awt.Graphics g,
                  int cellLen)
        Draw the layer using the given cell length.
        Specified by:
        paint in interface ILayerDrawer
        Parameters:
        g - The graphic context passed by container.
        cellLen - The length of a cell in pixels.

      • setMouseListener

        public void setMouseListener​(ILayerMouseListener listener)
        Set a manager for mouse events. If not defined, mouse events are managed by the class itself.
        Parameters:
        listener - A ILayerMouseListener object.

      • performDblClickActionAt

        public boolean performDblClickActionAt​(int atX,
                                       int atY)
        If a mouse listener has been defined the double-click event, it is passed to it, otherwise it is shown a CellObjectChooser that allows the user to choose which object to be probed.
        Specified by:
        performDblClickActionAt in interface ILayerMouseListener
        Parameters:

        atY - The y coordinate of the clicked cell.
        Returns:
        always true if no mouse listener is defined. This value is used by caller to know if the layer wants to manage the event.

      • performRightClickActionAt

        public boolean performRightClickActionAt​(int atX,
                                         int atY)
        If a mouse listener has been defined the right-click event, it is passed to it, otherwise it is returned false.
        Specified by:
        performRightClickActionAt in interface ILayerMouseListener
        Parameters:
        atX - The x coordinate of the clicked cell.
        atY - The y coordinate of the clicked cell.
        Returns:
        always false if no mouse listener is defined. This value is used by caller to know if the layer wants to manage the event.

      • performMouseMovedFromTo

        public boolean performMouseMovedFromTo​(int fromX,
