lazarus menu组件(2024-11-15增加菜单阴影)

lazarus的menu控件在银河麒麟显示(GTK2)灰黑色背景，荆通大神通过修改gtk2源码（gtk2proc.inc和gtk2wsmenus.pp）可以修改背景但效果还是不理想。近日在GitHub找到一个LazarusMenu，经试用发现问题很多，其中还使用了bgracontrols控件。

我修改的版本删除bgracontrols控件，修正了大量的Bug，已可以使用。

修改TAdvancedMenu的menu背景及高亮颜色：

unit TAdvancedMenu;

{$mode ObjFPC}{$H+}

interface

uses
  Classes, SysUtils, Forms, Controls, Graphics, Dialogs, Menus, StdCtrls, ExtCtrls,
  dataTypes;

const
  MenuBackColor  = clWhite;              //menu背景颜色
  MenuItemTextColor  = clBlack;          // menu文字颜色
  MenuHighlightColor =clInactiveCaption; //激活时的颜色
  MenuItemHighlightTextColor = clBlack;  //激活时文字颜色

在unit添加TAdvancedMenu单元。
demo:

unit Unit1;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils, Forms, Controls, Graphics, Dialogs, ExtCtrls, Menus,
  TAdvancedMenu, Themes,ActnList, LCLProc;

type
  { TForm1 }
  TForm1 = class(TForm)
    Action1: TAction;
    ActionList1: TActionList;
    Panel2: TPanel;
    procedure FormCreate(Sender: TObject);
    procedure FileClick(Sender: TObject);
    procedure quitApplication(Sender: TObject);
    procedure printData(Sender: TObject);
    procedure sendData(Sender: TObject);
  private

  public

  end;
