Package org.locationtech.jts.jump.workbench.ui.cursortool

Class AbstractCursorTool

java.lang.Object

org.locationtech.jts.jump.workbench.ui.cursortool.AbstractCursorTool

All Implemented Interfaces:

MouseListener, MouseMotionListener, EventListener, CursorTool

Direct Known Subclasses:

DragTool, MultiClickTool, SnapIndicatorTool

public abstract class AbstractCursorTool
extends Object
implements CursorTool

A tool that draws an XOR visual indicator. Subclasses need not keep track of the XOR state of the indicator -- that logic is all handled by this class. Even if the LayerViewPanel is repainted while the XOR indicator is on-screen.

Constructor Detail

AbstractCursorTool

public AbstractCursorTool()

Method Detail

allowSnapping

public void allowSnapping()

Makes this CursorTool obey the snapping settings in the Options dialog.

wasShiftPressed

protected boolean wasShiftPressed()

wasControlPressed

protected boolean wasControlPressed()

createCursor

public static Cursor createCursor(Image image)

The cursor will look best if the image is a 32 x 32 transparent GIF.

createCursor

public static Cursor createCursor(Image image,
                                  Point hotSpot)

getCursor

public Cursor getCursor()

Specified by:

getCursor in interface CursorTool

isGestureInProgress

public boolean isGestureInProgress()

Used by OrCompositeTool to determine whether a CursorTool is busy interacting with the user.

Specified by:

isGestureInProgress in interface CursorTool

isRightMouseButtonUsed

public boolean isRightMouseButtonUsed()

Specified by:

isRightMouseButtonUsed in interface CursorTool

Returns:

true if this CursorTool uses the right mouse button; false to allow the panel to show a popup-menu on right-clicks
