Delphi XE4 IDE，如何始终隐藏对象检查器的底部窗格

Question

Obeject Inspector 底部的两个窗格完全没有用，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。

Answer 1

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

更新这个答案的原始版本需要一个包，包括一个插件表单和一个按钮来刷新对象检查器以隐藏这两个 不需要的物品。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DesignNotification 对象替换了以前的 IDENotifier 并使用它的 SelectionChanged 事件调用隐藏THotCommands 和TDescriptionPane 控件的代码。 TDesignNotification 在 DesignIntf​​.Pas 中实现 IDesignNotification 接口

另一个对隐藏过程自动运行至关重要的细节是将THotCommands 和TDescriptionPane 控件的Height 设置为0，因为IDE 似乎重置了它们的Visible在更改 OI 中的组件选择后，属性为 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;

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

  inherited Create;

  AGoingDormant: Boolean);

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;

procedure TDesignNotification.HideItems;
var
  i : Integer;
  Form : TForm;
begin
  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;
  AResurrecting: Boolean);
