TCalendar年历可以让某些日期自定义填充颜色吗

TCalendar日历可以让某些日期自定义填充颜色吗?
就是软件的工作日志查看,在日历上想有有操作日志的日期标出来.

刚才看了看，原来TCCalendar是继承自TCustomGrid，这样就好办了：

class TCrnCalendar: public TCCalendar

{

public:

    void __fastcall DrawCell(int ACol, int ARow, const TRect &ARect,

            TGridDrawState AState)

    {

        // 假设第4行第3列需要变色

        if (ACol == 2 && ARow == 3)

        {

            Canvas->Brush->Color = clSkyBlue;

            Canvas->Font->Color = clRed;

            Canvas->Font->Style = Canvas->Font->Style << fsBold;

        }

        else

        {

            Canvas->Brush->Color = clWhite;

            Canvas->Font->Color = clBlack;

            Canvas->Font->Style = Canvas->Font->Style >> fsBold;

        }


        TCCalendar::DrawCell(ACol, ARow, ARect, AState);

    }

    __fastcall virtual TCrnCalendar(TComponent *AOwner): TCCalendar(AOwner)

    {}

};



void __fastcall TForm1::Button1Click(TObject *Sender)

{

    TCrnCalendar *cc = new TCrnCalendar(this);

    cc->Parent = this;

    cc->Left = 100;

    cc->Top = 100;


    cc->Show();

}
