Question

位于Obeject Inspector底部的两个窗格根本没用，而且它不必要地消耗屏幕，如下面的屏幕截图所示。如何在重新启动IDE后禁用这两个窗格？内置选项或第三方插件对我来说没问题。谢谢。

下面的XE4代码显示了如何隐藏要删除的项目：它们是实例课程THotCommands和TDescriptionPane。

更新此答案的原始版本需要一个包，其中包含一个加载项窗体和一个按钮，用于刷新Object Inspector以隐藏两个不需要的物品在下面的代码中，我完全删除了表单，现在隐藏的项目应该是全自动的。为实现这一目标，我用DesignNotification对象替换了以前的IDENotifier并使用它 SelectionChanged事件，用于调用隐藏THotCommands和TDescriptionPane控件的代码。 TDesignNotification在DesignIntf.Pas

中实现IDesignNotification接口

对于让隐藏过程自动运行至关重要的其他细节是将Height和THotCommands控件的TDescriptionPane设置为0，因为IDE似乎在OI中的组件选择更改后，将Visible属性重置为True。幸运的是，无论什么代码都没有将其高度重置为非零值。

显然，要使用将包含代码的单元添加到包（.Dpk）文件中，然后在IDE中编译并安装该包。

代码：

interface

uses
  [...]ToolsApi, DesignIntf;

type
  TDesignNotification = class(TInterfacedObject, IDesignNotification)
    procedure ItemDeleted(const ADesigner: IDesigner; AItem: TPersistent);
    procedure ItemInserted(const ADesigner: IDesigner; AItem: TPersistent);
    procedure ItemsModified(const ADesigner: IDesigner);
    procedure SelectionChanged(const ADesigner: IDesigner;
      const ASelection: IDesignerSelections);
    procedure DesignerOpened(const ADesigner: IDesigner; AResurrecting: Boolean);
    procedure DesignerClosed(const ADesigner: IDesigner; AGoingDormant: Boolean);
    constructor Create;
    destructor Destroy; override;

    procedure HideFormItems(Form: TForm);

  l : Integer;

  procedure HideControl(AControl : TControl);
  begin
    AControl.Height := 0;  //  This is necessary because the IDE seems to reset
    //  Visible to True when the Object Inspector is refreshed.
    AControl.Visible := False;
  end;

begin
  HideCount := 0;
  for j := 0 to Form.ComponentCount - 1 do begin
    C := Form.Components[j];
    if C is TPanel then begin
      Panel := TPanel(C);
      for l := 0 to Panel.ControlCount - 1 do begin
        if CompareText(Panel.Controls[l].ClassName, 'TDescriptionPane') = 0 then begin
          HideControl(Panel.Controls[l]);
          Inc(HideCount);
        end
        else
          if CompareText(Panel.Controls[l].ClassName, 'THotCommands') = 0 then begin
            HideControl(Panel.Controls[l]);
            Inc(HideCount);
          end;
        if HideCount >= 2 then  //  we're done
          exit;
