<UL>
|
|
<LI>The function does not check if the mouse cursor is currently within the
|
|
given rectangle. Placing the mouse cursor within the bounding box is the
|
|
responsibility of the programmer.</LI>
|
|
<LI>While the bounding box may be larger than the actual screen size, the
|
|
standard mouse cursor draw routines may fail to set the cursor to coordinates
|
|
outside of the screen area. Depending on the platform, you may have to supply
|
|
your own mouse cursor routines.</LI>
|
|
<LI>The function is only available as fastcall function, so it may only be
|
|
used in presence of a prototype.</LI>
