我有一个名为TMenuItemSelector的组件,它有两个已发布的属性：PopupMenu – 允许从表单中选择TPopupMenu的实例,而MenuItem允许从表单中选择任何TMenuItem实例.

我想以一种方式修改MenuItem属性的属性编辑器,当分配PopupMenu时,只有来自此PopupMenu的菜单项在下拉列表中可见.

我知道我需要编写自己的TComponentProperty后代并覆盖GetValues方法.问题是我不知道如何访问TMenuItemSelector所在的表单.

原始TComponentProperty使用此方法迭代所有可用实例：

procedure TComponentProperty.GetValues(Proc: TGetStrProc);
begin
  Designer.GetComponentNames(GetTypeData(GetPropType),Proc);
end;

但是,Designer似乎是预编译的,所以我不知道GetComponentNames是如何工作的.

这是我到目前为止所做的,我想我唯一缺少的是GetValues的实现：

unit uMenuItemSelector;

interface

uses
  Classes,Menus,DesignIntf,DesignEditors;

type
  TMenuItemSelector = class(TComponent)
  private
    FPopupMenu: TPopUpMenu;
    FMenuItem: TMenuItem;
    procedure SetPopupMenu(const Value: TPopUpMenu);
    procedure SetMenuItem(const Value: TMenuItem);
  published
    property PopupMenu: TPopUpMenu read FPopupMenu write SetPopupMenu;
    property MenuItem: TMenuItem read FMenuItem write SetMenuItem;
  end;

type
  TMenuItemProp = class(TComponentProperty)
  public
    function GetAttributes: TPropertyAttributes; override;
    procedure GetValues(Proc: TGetStrProc); override;
  end;

procedure Register;

implementation

procedure Register;
begin
  Registerpropertyeditor(TypeInfo(TMenuItem),TMenuItemSelector,'MenuItem',TMenuItemProp);
  RegisterComponents('Test',[TMenuItemSelector]);
end;

{ TMenuItemSelector }

procedure TMenuItemSelector.SetMenuItem(const Value: TMenuItem);
begin
  FMenuItem := Value;
end;

procedure TMenuItemSelector.SetPopupMenu(const Value: TPopUpMenu);
begin
  FPopupMenu := Value;
end;

{ TMenuItemProperty }

function TMenuItemProp.GetAttributes: TPropertyAttributes;
begin
  Result := inherited GetAttributes + [paValueList,paSortList];
end;

procedure TMenuItemProp.GetValues(Proc: TGetStrProc);
begin
  //How to filter MenuItems from the form in a way that only
  //MenuItems which belong to TMenuItemSelector.PopupMenu are displayed? \
  //And how to get to that form?
  //inherited;

end;

end.

有人可以帮忙吗？

谢谢.

procedure TMenuItemProp.GetValues(Proc: TGetStrProc); 
var
  Selector: TMenuItemSelector;
  I: Integer;
begin 
  Selector := GetComponent(0) as TMenuItemSelector;
  if Selector.PopupMenu <> nil then
  begin
    with Selector.PopupMenu.Items do
    begin
      for I := 0 to Count-1 do
        Proc(Designer.GetComponentName(Items[I]));
    end;
  end else
    inherited GetValues(Proc);
end;

顺便说一句,您需要在单独的包中实现TMenuItemSelector和TMenuItemProp.除了RegisterComponents()函数(在运行时包中实现)之外,不允许将设计时代码编译为运行时可执行文件.这是针对EULA的,Embarcadero的设计时间版本不允许分发.您需要在仅运行时的包中实现TMenuItemSelector,然后在仅设计时的包中实现TMenuItemProp和Register(),该包需要仅运行时包并使用声明TMenuItemSelector的单元,例如：

unit uMenuItemSelector;

interface

uses
  Classes,Menus;

type
  TMenuItemSelector = class(TComponent)
  private
    FPopupMenu: TPopUpMenu;
    FMenuItem: TMenuItem;
    procedure SetPopupMenu(const Value: TPopUpMenu);
    procedure SetMenuItem(const Value: TMenuItem);
  protected
    procedure Notification(AComponent: TComponent; Operation: TOperation); override;
  published
    property PopupMenu: TPopUpMenu read FPopupMenu write SetPopupMenu;
    property MenuItem: TMenuItem read FMenuItem write SetMenuItem;
  end;

implementation

{ TMenuItemSelector }

procedure TMenuItemSelector.Notification(AComponent: TComponent; Operation: TOperation);
begin
  inherited;
  if Operation = opRemove then
  begin
    if AComponent = FPopupMenu then
    begin
      FPopupMenu := nil;
      FMenuItem := nil;
    end
    else if AComponent = FMenuItem then
    begin
      FMenuItem := nil;
    end;
  end;
end;

procedure TMenuItemSelector.SetMenuItem(const Value: TMenuItem);
begin
  if FMenuItem <> Value then
  begin
    if FMenuItem <> nil then FMenuItem.RemoveFreeNotification(Self);
    FMenuItem := Value;
    if FMenuItem <> nil then FMenuItem.FreeNotification(Self);
  end;
end;

procedure TMenuItemSelector.SetPopupMenu(const Value: TPopUpMenu);
begin
  if FPopupMenu <> Value then
  begin
    if FPopupMenu <> nil then FPopupMenu.RemoveFreeNotification(Self);
    FPopupMenu := Value;
    if FPopupMenu <> nil then FPopupMenu.FreeNotification(Self);
    SetMenuItem(nil);
  end;
end;

end.
