Class AbstractShapeHandle

java.lang.Object

com.inductiveautomation.ignition.designer.designable.controls.AbstractShapeHandle

All Implemented Interfaces:

IHandle

Direct Known Subclasses:

AbstractShapeTool.AbstractShapeControls.AbstractShapeManipulationHandle, RotationControls.AbstractRotationHandle, RotationControls.RotationAnchorHandle, ScaleControls.AbstractResizeHandle

public abstract class AbstractShapeHandle
extends java.lang.Object
implements IHandle

This class is a useful base class for most handle implementations. It knows how to represent itself with a shape provided by the subclass. It also has all of IHandle's methods stubbed out so a subclass can only implement what it is interested in.

Field Detail

drawShape

protected java.awt.Shape drawShape

The shape that represents this IHandle. Initialized in newDrawShape()

AbstractShapeHandle

protected AbstractShapeHandle()

Method Detail

paintHandle

public void paintHandle(DesignPanel panel,
                        java.awt.Graphics2D g,
                        ShapePaint paint)

newDrawShape

protected java.awt.Shape newDrawShape()

Called to create a new draw shape. Expectation is that a subclass will override this to provide a meaningful shape. Anchor point is at (0,0). Default shape is a 10x10 square anchored in the center.

getBounds

public java.awt.Rectangle getBounds(DesignPanel panel)

Description copied from interface: IHandle

Return the bounds of this handle, in 2d (zoomed) space.

Specified by:

getBounds in interface IHandle

position

protected abstract void position(java.awt.geom.Point2D.Double location)

Updates the argument location with the correct position of this handle's anchor point. Must be in logical (unzoomed) coordinates.

getStatusBarText

public java.lang.String getStatusBarText(int inputMask)

Description copied from interface: IHandle

Called on mouseover and during drag to get the status bar text for the handle.

Specified by:

getStatusBarText in interface IHandle

onClick

public void onClick(int inputMask)

Description copied from interface: IHandle

The mouse was clicked within the handle's bounds.

Specified by:

onClick in interface IHandle

onDrag

public void onDrag(double dX,
                   double dY,
                   int inputMask)

Description copied from interface: IHandle

Called while the handle is being dragged.

Specified by:

onDrag in interface IHandle

Parameters:

dX - The distance along the horizontal axis away from the drag starting point. (Unzoomed, logical)

dY - The distance along the vertical axis away from the drag starting point. (Unzoomed, logical)

inputMask - The extended modifiers from the underlying mouse drag (see MouseEvent.getModifiersEx().)

onDragStart

public void onDragStart(double dX,
                        double dY,
                        int inputMask)

Description copied from interface: IHandle

The handle has started to be dragged.

Specified by:

onDragStart in interface IHandle

Parameters:

dX - The distance along the horizontal axis away from the drag starting point. (Unzoomed, logical)

dY - The distance along the vertical axis away from the drag starting point. (Unzoomed, logical)

inputMask - The extended modifiers from the underlying mouse drag (see MouseEvent.getModifiersEx().)

onDragEnd

public void onDragEnd(double dX,
                      double dY,
                      int inputMask)

Description copied from interface: IHandle

The drag event is complete (mouse has been released).

Specified by:

onDragEnd in interface IHandle

Parameters:

dX - The distance along the horizontal axis away from the drag starting point. (Unzoomed, logical)

dY - The distance along the vertical axis away from the drag starting point. (Unzoomed, logical)

inputMask - The extended modifiers from the underlying mouse drag (see MouseEvent.getModifiersEx().)
