Method Detail

computeObjectSelected

public Object computeObjectSelected(IlvBasicView view,
                                    String[] params)

This method returns the object that was selected in the specified coordinates in manager coordinates system.
The parameters passed to this method are:

• params[0]: the x coordinate of the clicked point.
• params[1]: the y coordinate of the clicked point.
• params[2]: the x coordinate of the current view bounding box.
• params[3]: the y coordinate of the current view bounding box.
• params[4]: the width of the current view bounding box.
• params[5]: the height of the current view bounding box.
• params[6]: the width of the image.
• params[7]: the height of the image.

This method will decode the parameters and call the computeObjectSelected(IlvFacesView, IlvPoint, IlvTransformer) method, so subclasses should override this method.

Specified by:

computeObjectSelected in interface IlvObjectSelectedFinder

Parameters:

view - The faces view component.

params - The parameter array.

Returns:

The clicked object or a collection of objects.
