delphi cxgrid +toolBar做一个紧贴表头的条件搜索框

效果图:

type
  TFrame2 = class(TFrame)
    Panel1: TPanel;
    TV: TcxGridDBTableView;
    cxGrid1Level1: TcxGridLevel;
    cxGrid1: TcxGrid;
    TVColumnName: TcxGridDBColumn;
    TVColumnAge: TcxGridDBColumn;
    TVColumnAddress: TcxGridDBColumn;
    scToolBar1: TscToolBar;
    Edit2: TEdit;
    Edit3: TEdit;
    Edit1: TEdit;
    procedure FrameResize(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
    constructor Create(AOwner: TComponent); override;
    procedure ToResize();
  end;

implementation

{$R *.dfm}

constructor TFrame2.Create(AOwner: TComponent);
begin
  inherited Create(AOwner);
  Self.Align := alClient;
end;

procedure TFrame2.FrameResize(Sender: TObject);
begin
  ToResize();
end;

procedure TFrame2.ToResize();

　　//注意红色部分.如果直接使用TVColumnName.Width 只能取到列的预设宽度
  w1 := TV.ViewInfo.HeaderViewInfo.Items[TVColumnName.Index].Width;
  Edit1.width := w1;
  Edit1.Text := 'name: ' + w1.ToString;

  w2 := TV.ViewInfo.HeaderViewInfo.Items[TVColumnAge.Index].Width;
  Edit2.width := w2;
  Edit2.Text := 'age: ' + w2.ToString;

  w3 := TV.ViewInfo.HeaderViewInfo.Items[TVColumnAddress.Index].Width;
  Edit3.width := w3;
  Edit3.Text := 'address: ' + w3.ToString;
end;
