Handle of current object
h = gco
h = gco(figure_handle)
h = gco returns the handle
of the current object.
h = gco(figure_handle) returns
the handle of the current object in the figure specified by
The current object is the last object clicked
or selected via keyboard interaction, excluding
uimenus. If the mouse click did not occur
over a figure child object, the figure becomes the current object. The MATLAB® software
stores the handle of the current object in the figure's
An object can become the current object as a result of pressing the space bar to invoke a callback in a dialog when a uicontrol in that dialog has focus (usually the result of using the Tab key to change focus).

gcbo provides the only completely
reliable way to retrieve the handle to the object whose callback is
executing, at any point in the
