TAutoCursor AutoCursor;

Place the statement above at the point in any function that an hourglass screen cursor should appear. When the function exits, the old screen cursor will be restored (usually an arrow) by AutoCursor's destructor.

With AutoCursor, there's no need to write "Screen->Cursor = crDefault;" before every possible function exit point.

class TAutoCursor
TCursor OldCursor;
TAutoCursor() {OldCursor = Screen->Cursor; Screen->Cursor = crHourGlass;}
~TAutoCursor(){Screen->Cursor = OldCursor;}

While AutoCursor exists, the screen cursor can still be manually changed to any TCursor desired.

This class can be enhanced by adding another constructor to the class to take the startup cursor desired:

TAutoCursor(TCursor Value){OldCursor = Screen->Cursor; Screen->Cursor = Value;}

The usage would then be:

TAutoCursor AutoCursor(crHandPoint); //or any other TCursor type
