delphi – 我需要有关如何实现可以在对象Inspector中显示的类的

发布时间：2020-12-15 10:04:16 所属栏目：大数据来源：网络整理

导读：我有 ... TDispPitch = class private iLineSize: Integer; iLineColor: TColor; bDisplayAccent: Boolean; bVisible: Boolean; published property LineSize : Integer read iLineSize write iLineSize; ...etc end;... 我想在Object Insepector中显示此功

我有

...
  TDispPitch = class
  private
    iLineSize: Integer;
    iLineColor: TColor;
    bDisplayAccent: Boolean;
    bVisible: Boolean;
  published
    property LineSize : Integer read iLineSize write iLineSize;
    ...etc
  end;
...

我想在Object Insepector中显示此功能来编辑设置.

我尝试添加

property DispPitch: TDispPitch read FDispPitch write FDispPitch. like

可以显示DispPitch但我看不到它的属性.比如LineSize,LineColor等

解决方法

您必须从TPersistent或后代派生您的类,以使其在Object Inspector中可用：

TDispPitch = class(TPersistent)
private
  ...
published
  property ...
  ...
end;

来自Delphi文档：

TPersistent is the ancestor for all objects that have assignment and streaming capabilities.
