AW: StringGrid-Komponente mit Checkbox

  Alt 10. Apr 2017, 18:11
hallo freunde,
danke für den tip hier.
Doch mein Probleme sind in meinem Prg 2:

1) Zeichne nur alle 2. Rows eine Checkbox. (rote Pfeile)
EDIT: Lösung zu 1 einfach mit mod einschränken
Delphi-Quellcode:
begin
  with TStringGrid(Sender) do
    if ((Arow mod 2)=0) and ((ACol in CheckBoxCols) and not (gdFixed in State) )then
    begin
      Canvas.FillRect(Rect);
      InflateRect(Rect, -4, -4);
      DrawFrameControl(Canvas.Handle, Rect,DFC_Button,
                       CheckBox(Trim(Cells[ACol, ARow])));
    end; // if gdFixed in State
end;




2) Kann man zu jeder row in Col=0 die zweite nachfolgende Row zusammenfassen, so daß beide Zeilen in einer Cell drin sind. (grün Feile)

Mein Code:
Delphi-Quellcode:
unit DelphiForm;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Vcl.Grids;

type
  TForm2 = class(TForm)
    ButtonQMCcalc: TButton;
    Memo1: TMemo;
    CheckBox1: TCheckBox;
    CheckBox2: TCheckBox;
    Label1: TLabel;
    Edit1: TEdit;
    Memo2: TMemo;
    ButtonTTCreate: TButton;
    StringGrid1: TStringGrid;
    procedure ButtonQMCcalcClick(Sender: TObject);
    procedure ButtonTTCreateClick(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure FormClose(Sender: TObject; var Action: TCloseAction);
    procedure StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
      Rect: TRect; State: TGridDrawState);
    procedure StringGrid1MouseDown(Sender: TObject; Button: TMouseButton;
      Shift: TShiftState; X, Y: Integer);
