The filename of the cursor file displayed when the mouse is over the button.
It is possible to use normal cursors files (extension .CUR) or animated cursors files (extension .ANI).
This property can be changed at design time using the Resources tab of the 3D Button Visual Editor application.
Notes
Note that setting the cursor at design time will not require to redistribute the cursor file because its binary will be stored in the final application code in a compressed format (the redistribution is required only when there is the need of changing and restoring the cursor at runtime).
