关于Dbgrid显示的问题?

[chengxuejun1]

在数据表中有一个逻辑型字段,如何使它在Dbgrid1上以复选框形式出现?如何使复选框的值与数据表中的逻辑型字段值对应起来?

用DXDBGRID
可以实现checkbox,lookup,treeview的功能

也可以通过DBGRID的单元重绘来解决，看一下昨天的论坛
有DBGRID的单元重绘的详细编码。

这是我的一个程序：
C++Builder 的，与Delphi原理一样


void __fastcall TW_MM_P_Receive::dbgIncomeDrawColumnCell(TObject *Sender,
const TRect &Rect, int DataCol, TColumn *Column,
TGridDrawState State)
{
int iLeft = 0;
if (Column->FieldName == "Checked")
{
iLeft =(Rect.Right-Rect.Left-10)/2 + 1/2;

dbgIncome->Canvas->Brush->Color =clWhite; //去掉阴影
dbgIncome->Canvas->FillRect(Rect);

dbgIncome->Canvas->Pen->Color =clBlue; //
dbgIncome->Canvas->Pen->Width =2;

dbgIncome->Canvas->MoveTo(Rect.Left+iLeft,Rect.Top+3);
dbgIncome->Canvas->LineTo(Rect.Left+iLeft+10,Rect.Top+3);
dbgIncome->Canvas->LineTo(Rect.Left+iLeft+10,Rect.Top+13);
dbgIncome->Canvas->LineTo(Rect.Left+iLeft,Rect.Top+13);
dbgIncome->Canvas->LineTo(Rect.Left+iLeft,Rect.Top+2);

if (adoqIncome->FieldByName("Checked")->AsString == "1")
{
dbgIncome->Canvas->MoveTo(Rect.Left+iLeft,Rect.Top+6);
dbgIncome->Canvas->LineTo(Rect.Left+iLeft+4,Rect.Top+11);
dbgIncome->Canvas->LineTo(Rect.Left+iLeft+12,Rect.Top+1);
}
}
}
