寻找控件的后构造函数事件 [英] Looking for a Post-Constructor Event of a Control

问题描述

我已经创建了一个 Label 子类，并需要初始化其几个属性。

一些我可以在构造函数中设置，但其他人正在窗体的设计器代码中重置，因此必须设置

$在设计者完成其 InitializeComponent

之后但在<$ c之前的b $ b

• $ c> Paint 事件运行，需要它们。

我现在正在使用一个解决方法：我设置一个标志 bool needsInit = true; Paint 事件中检查的如果为true，我调用 doInit（）方法，清除标志并进行初始化。

<对于运行的窗体和VS设计器窗口..但我闻到一个标志

所以，也许有一个更好的，做吗？

解决方案

覆盖InitLayout方法。

  protected override void InitLayout（）
 {
 //这里做一些事情
 base.InitLayout（）; 
} 
  

I have made a Label subclass and need to initialize a few of its Properties.

Some I can set in the constructor, but others are being reset in the designer code of the form, so they must be set

• after the designer has done its InitializeComponent
• but before the Paint event runs, which needs them in place.

Of course the control should be self-sufficient, so I can't add anything to the form's code.

I am using a workaround now: I set a flag bool needsInit = true; which I check in the Paint event. If true I call a doInit() method, which clears the flag and does the initializations.

It works, both for the running Form and for the VS Designer window.. but I smell a flag

So is there maybe a better, flagless way to do it? Or the Right Way?

解决方案

Override the InitLayout method.

protected override void InitLayout()
{
    // do something here
    base.InitLayout();
}
