这句delphi怎么翻译成C++Builder
if (htOnStateIcon in
treeview.GetHitTestInfoAt(point1.X,point1.Y)) then

[解决办法]

THitTests HT = TreeView1-> GetHitTestInfoAt(point1.X,point1.Y);

if (HT.Contains(htOnItem) || HT.Contains(htOnIcon) || HT.Contains(htOnButton))
{

}
[解决办法]
"in "是delphi的集合操作符。。。
对应BCB要判断的话，应该是用 " < < "移位操作符判断。。。
