Class InputEventForwarder

java.lang.Object

info.bioinfweb.libralign.alignmentarea.content.InputEventForwarder

All Implemented Interfaces:

TICKeyListener, TICMouseListener, TICMouseWheelListener, java.util.EventListener

public class InputEventForwarder
extends java.lang.Object
implements TICKeyListener, TICMouseListener, TICMouseWheelListener

Forwards key and mouse events received by an AlignmentContentArea to the respective AlignmentSubArea. For key events that is the first sequence area currently containing the cursor and for mouse events the are containing the point where the mouse event occurred.

Instances of this class are used when AlignmentSubAreas paint directly on the toolkit component of AlignmentContentArea (currently only optionally the case in SWT) to allow the subareas to receive input events, even if they have no associated toolkit component. (Since no toolkit components for the subareas exists, it is not possible to determine the subarea owning the focus, which is why the alignment cursor position defines the receiver subarea for key events.)

Events are not forwarded directly but copies are created that reference the respective AlignmentSubArea as the source and mouse event coordinates are transformed to the coordinate system origin used by the respective AlignmentSubArea.

This class is used by LibrAlign components internally. There is usually no need to reference it directly in application code.
