如何在不知道组件名称的情况下访问组件的属性? [英] How to access component's properties without knowing its name?

问题描述

是否有一种方法可以使用运行时创建的组件的属性而不知道其名称?意思是说，在您完成此操作之后.

Is there a way to use the properties of a component created in run-time without knowing its name? And by this I mean after you already done this.

with TPanel.Create(self) do
  begin
  Name := 'Panel' + IntToStr(ComponentCount + 1);
  Height := 50;
  Width := 100;
  Top := 30;
  Left := 30;
  Parent := self;
  end;

推荐答案

声明类型为 TPanel 的变量，并将对组件的引用存储在该变量中.

Declare a variable of type TPanel and store a reference to your component in that variable.

var
  Panel: TPanel;
.... 
Panel := TPanel.Create(Self);

然后可以使用此变量引用控件.

You can then refer to the control using this variable.

您可能需要将变量作为表单的成员字段，数组或其他容器保存.

You will likely need to hold the variable as a member field of the form, or in an array, or indeed some other container.
