//更换窗体或某个控件的光标可以不通过 Screen 对象, 譬如:
begin
Self.Cursor := crAppStart;
Panel1.Cursor := crHandPoint;

{光标可选值:
crDefault = TCursor(0);
crNone = TCursor(-1);
crArrow = TCursor(-2);
crCross = TCursor(-3);
crIBeam = TCursor(-4);
crSize = TCursor(-22);
crSizeNESW = TCursor(-6);
crSizeNS = TCursor(-7);
crSizeNWSE = TCursor(-8);
crSizeWE = TCursor(-9);
crUpArrow = TCursor(-10);
crHourGlass = TCursor(-11);
crDrag = TCursor(-12);
crNoDrop = TCursor(-13);
crHSplit = TCursor(-14);
crVSplit = TCursor(-15);
crMultiDrag = TCursor(-16);
crSQLWait = TCursor(-17);
crNo = TCursor(-18);
crAppStart = TCursor(-19);
crHelp = TCursor(-20);
crHandPoint = TCursor(-21);
crSizeAll = TCursor(-22);
}
//其中 crDefault 是默认光标
end;
--------------------------------------------------------------------------------

//使用 Screen 更换光标, 是给本程序的全局更换光标, 譬如:
begin
Screen.Cursor := crSize;
end;
--------------------------------------------------------------------------------

//如果让控件有不同的光标, Screen.Cursor 必须是默认值, 也就是:
Screen.Cursor := crDefault;
