Un TCheckGroup est un contrôle qui comporte un groupe d'articles avec des TCheckBox placé dans un composant conteneur.

Usage

Pour utiliser un TCheckGroup sur une fiche, vous pouvez simplement le sélectionner dans l'onglet Standard de la palette de composants et le placer en cliquant sur la fiche.

Petit exemple

Il modifie la couleur de fond d'une fiche. Cette couleur est obtenue en additionnant les composants individuelles de couleur :

pascal
procedure TForm1.cgRedItemClick(Sender: TObject; Index: integer);
var
  i, c: Integer;
begin
  c := $000000;                                         // first the color is black
  for i := 0 to 7 do begin                              // test Items 0..7 of all Checkgroups
    if cgRed.Checked[i]   then c := c + 1 shl i;        // amount of red   $000000..$0000FF
    if cgGreen.Checked[i] then c := c + 1 shl (i + 8);  // amount of green $000000..$00FF00
    if cgBlue.Checked[i]  then c := c + 1 shl (i + 16); // amount of blue  $000000..$FF0000
  end;
  Color := c;
end;
