For Russell on OnMeasureItem answer

----------------------------------------------------------
1. Make sure the menu/popupmenu has OwnerDraw set to true.
2. You have to handle the OnMeasureItem for the menu items, and change the Width Setting there.  The easiest way to do this is to create one method and assign all the menu items OnMeasureItem to it.

Russell,

I can't find the OnMeasureItem for PopupMenu, it is under PopupMenu.Items.

Can you show me smoe sample code? Thanks.

MyMenuItem1.OnMeasureItem := MyMeasureItem;
MyMenuItem2.OnMeasureItem := MyMeasureItem;
MyMenuItem3.OnMeasureItem := MyMeasureItem;
etc.

Or you can do it visually by creating an event handler for the first handler, then clicking on the event handler for the rest of the menu items and selecting the one created first. The Sender parameter will then contain the menuitem that it is measuring.

The OnMeasureItem is not an event of the popupmenu/menu, but rather of the menu items (TMenuItem).

Simple example that binds all the popup menu items OnMeasureItem to a forms method

type
  TForm1            =  class(TForm)
     PopupMenu1:    TPopupMenu;
     miOne:         TMenuItem;
     miTwo:         TMenuItem;
     miThree:       TMenuItem;
     procedure      FormCreate(Sender: TObject);
     // Added to handle the OnMeasureItem for the menu items
     procedure      OnMeasureItem(Sender: TObject; ACanvas: TCanvas; var Width, Height: Integer);
     // Added so you can bind the popupup menu items to the forms OnMeasureItem handler
     procedure      BindPopupMenu(PopupMenu: TPopupMenu);
  private
     // Private declarations
  public
     // Public declarations
  end;

var
  Form1:            TForm1;

implementation
{$R *.DFM}

procedure TForm1.BindPopupMenu(PopupMenu: TPopupMenu);
var  dwIndex:    Integer;
begin

  // Make sure OwnerDraw is set
  PopupMenu.OwnerDraw:=True;

  // Iterate the items
  for dwIndex:=0 to Pred(PopupMenu.Items.Count) do
     // Set the OnMeasureItem event handler
     PopupMenu.Items[dwIndex].OnMeasureItem:=OnMeasureItem;

end;

procedure TForm1.OnMeasureItem(Sender: TObject; ACanvas: TCanvas; var Width, Height: Integer);
begin

  // Adjust the width only (set to your desired width)
  Width:=30;

end;

procedure TForm1.FormCreate(Sender: TObject);
begin

  // Bind PopupMenu1 to the form handler for OnMeasureItem
  BindPopupMenu(PopupMenu1);

end;


Hope this helps,
Russell
