如何更改HTMLPanel的html [英] How to change the html of a HTMLPanel

问题描述

我想要声明一个HTMLPanel的子类。
在构造函数中，我想给它几个参数来构造包含html。

因为我必须将超级构造函数作为第一个语句，所以我必须在构造函数中稍后更改html。

我该如何做？

  public class MyHTMLPanel extends HTMLPanel 
 {
 public MyHTMLPanel（String id，int anotherParameter）
 {super（）; 
 String html =
 // ...一些代码构造html 
 // ??? this.setHtml（HTML）; 
 
 
 
 $ div $解析方案

你不需要子类化HTMLPanel。您可以创建一个简单的Composite组件：

  public class myPanel extends Composite {
 
 private HTMLPanel panel =新的HTMLPanel（）; 
 $ b $ public myPanel（String id，int anotherParameter）{
 //根据您的参数将HTML设置为面板
 initWidget（panel）; 
} 
} 
  




I want do declare a Subclass of an HTMLPanel. In its constructor I want to give it a few paramters to construct the containing html.

Because I have to call the super-constructor as first statement, I have to change the html later in the constructor.

How can I do this?

public class MyHTMLPanel extends HTMLPanel
{ 
  public MyHTMLPanel(String id, int anotherParameter)
  { super("");
     String html=""
    // ... some code th construct the html
    //??? this.setHtml(html);  
  }  
}

解决方案

You don't need to subclass HTMLPanel. You can create a simple Composite widget:

public class myPanel extends Composite {

    private HTMLPanel panel = new HTMLPanel();

    public myPanel(String id, int anotherParameter) {
        // set HTML to panel based on your parameters
        initWidget(panel);
    }
}
