The Elementary cursor is an internal smart object used to customize the mouse cursor displayed over objects (or widgets). In the most common scenario, the cursor decoration comes from the graphical engine Elementary is running on. Those engines may provide different decorations for cursors, and Elementary provides functions to choose them (think of X11 cursors, as an example).
By default, Elementary searches cursors only from engine. There's also the possibility of, besides using engine provided cursors, also use the ones coming from Edje theme files. Both globally and per widget, Elementary makes it possible for one to make the cursors lookup to be held on engines only or on Elementary's theme file, too. To set cursor's hot spot, two data items should be added to cursor's theme: "hot_x" and "hot_y", that are the offset from upper-left corner of the cursor (coordinates 0,0).

Set the cursor to be shown when mouse is over the object
Set the cursor that will be displayed when mouse is over the object. The object can have only one cursor set to it, so if this function is called twice for an object, the previous set will be unset. If using X cursors, a definition of all the valid cursor names is listed on Elementary_Cursors.h. If an invalid name is set the default cursor will be used.

obj | the object being set a cursor. |
cursor | the cursor name to be used. |
