位于 Obeject Inspector 底部的两个窗格根本没有用处，而且它不必要地占用了屏幕空间，如下面的屏幕截图所示。即使在重新启动 IDE 后如何禁用这两个窗格？内置选项或第三方插件对我来说没问题。谢谢。 在此处输入图像描述

下面的 XE4 代码显示了如何隐藏要删除的项目：它们是类THotCommands和TDescriptionPane.

更新这个答案的原始版本需要一个包，包括一个加载项表单和一个按钮来刷新对象检查器以隐藏两个不需要的项目。在下面的代码中，我完全删除了表单，项目的隐藏现在应该是全自动的。为了实现这一点，我用一个对象替换了之前的 IDENotifier，DesignNotification并使用它的 SelectionChanged事件来调用隐藏THotCommands和TDescriptionPane控件的代码。 TDesignNotification在 DesignIntf​​.Pas 中实现IDesignNotification接口

事实证明，对于让隐藏过程自动工作至关重要的另一个细节是将Height和THotCommands控件设置TDescriptionPane为 0，因为 IDE 似乎在更改 OI 中的组件选择后将其Visible属性重置为。True幸运的是，无论做什么代码都不会将它们的高度重置为非零值。

显然，要使用您将包含代码的单元添加到包 (.Dpk) 文件中，然后在 IDE 中编译和安装包。

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;
  private
    procedure HideItems;
    procedure HideFormItems(Form: TForm);
  end;

var
  DesignNotification : TDesignNotification;

implementation

procedure SetUp;
begin
  DesignNotification := TDesignNotification.Create;
  RegisterDesignNotification(DesignNotification);
end;

constructor TDesignNotification.Create;
begin
  inherited Create;
end;

procedure TDesignNotification.DesignerClosed(const ADesigner: IDesigner;

var
  j,
  l : Integer;
  Panel : TPanel;
  C : TComponent;
  HideCount : 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;
      end;
    end;
  end;
end;

  for i := 0 to Screen.FormCount - 1 do begin
    Form := Screen.Forms[i];
    if CompareText(Form.ClassName, 'TPropertyInspector') = 0 then begin
      HideFormItems(Form);
      Break;
    end;
  end;
end;

procedure TDesignNotification.DesignerOpened(const ADesigner: IDesigner;

  //  This can get called with ADesigner = Nil
  if ADesigner = Nil then
    exit;
  C := ADesigner.Root;
  if C <> Nil then begin

  end
end;

  SetUp;
finalization
  if DesignNotification <> Nil then begin
    UnRegisterDesignNotification(DesignNotification);
  end;
end.
