verschiedene label mittels variable ansteuern/eigenschaften ändern

[terence14]

Oder, wenn Du die Komponenten schon auf deinem Formular hast,

dann:

Delphi-Quellcode:

component-change_a_property_in_all_components_of_a_tform

change a property in all components of a form



procedure TForm1.SetProperties(ClassName, SomeProperty: string; Value: Integer);
var
  i: integer;
  PropInfo: PPropInfo;
  Component: TComponent;
begin
  for i := 0 to ComponentCount - 1 do
  begin
    Component := Components[i];
    if (Component is TControl) and ((Component.ClassName = ClassName)
      or (ClassName = 'AllComponents')) then
    begin
      PropInfo := GetPropInfo(Component.ClassInfo, SomeProperty);
      if Assigned(PropInfo) then
        SetOrdProp(Component, PropInfo, Integer(Value));
    end;
  end;
end;

// Examples, Beispiele:

procedure TForm1.Button1Click(Sender: TObject);
begin
  // Make all components readonly
  SetProperties('AllComponents', 'readonly', 1);
  // Make all components of Class TEdit invisible
  SetProperties('TEdit', 'visible', 0);
  // Set the Height Property of all TLabels
  SetProperties('TLabel', 'Height', 30);
  // Set ShowHint to false for all components
  SetProperties('AllComponents', 'ShowHint', 0);
  // Disable all TMemo Components
  SetProperties('TMemo', 'Enabled', 0);
  // Set Autosize to true for all TLabels
  SetProperties('TLabel', 'Autosize', 1);
end;
