请问这个问什么不对(0分)

那么这个呢？
void __fastcall TForm1::test2DrawItem(TObject *Sender, TCanvas *ACanvas, TRect &ARect, bool Selected)
{
//如果当前的菜单项是选择状态的话。那么将当前菜单项的范围填充为蓝色的。
if(Selected==true)
{
//如果想修改菜单项被选择时的颜色，请改这里。
ACanvas->Brush->Color=clRed;
ACanvas->FillRect(ARect);
}
}

up

给你一段代码试试看：
void __fastcall TForm1:rawItem(TMenuItem *MenuItem,TCanvas *ACanvas,TRect &DrawRect,bool Selected)
{
TColor BackGround;
if (Selected)
{
ACanvas->Pen->Color = clRed;
BackGround = clBlue;
Screen->Cursor = crHandPoint;
}
else
{
ACanvas->Pen->Color = clBtnFace;
BackGround = clBtnFace;
Screen->Cursor = crDefault;
}
ACanvas->Rectangle(DrawRect);
ACanvas->Brush->Color = BackGround;
ACanvas->FillRect(Rect(DrawRect.Left + 1,DrawRect.Top + 1,DrawRect.Right - 1,DrawRect.Bottom - 1));
ACanvas->Pen->Color = clBlack;
ACanvas->TextOutA(DrawRect.Left + 14,DrawRect.Bottom - 16,MenuItem->Caption);
}
这是前几天写的
