如何重新计算JComponent的首选大小？

我知道这样的事实，当我创建JComponent的实例时，它具有自己的首选大小。现在，我们假设我手动设置了JComponent的PreferredSize，尺寸为0
x0。我希望该Component“重置”其自己的preferredSize。我怎么做？

答案1

小编典典

1）将首选大小设置为null可以将组件重置为重新计算其首选大小，就像从未设置过一样。

component.setPreferredSize(null);

这可能并不能满足您的要求，具体取决于您发出的信号是应该重做布局的方式-但至少从技术上讲，这是您问题的答案。

2）一般建议不要使用setPreferredSize，请参阅这篇文章

Angular 2：如何在该Component中访问自定义Component的FormControl实例？

所以我一直在阅读如何在Angular2中构建自定义FormControls,但我无法得到我正在努力完成验证的工作.我有一个正常的输入控件,我想在自定义组件中包装,以便我可以这样做：

<my-control name="something" [(ngModel)]="model.something" required></my-control>

而不是每次都重复这个：

<divhttps://www.jb51.cc/tag/Feed/" target="_blank">Feedback" [ngClass]="{'has-success': someInput.valid,'has-error': someInput.invalid && someInput.dirty}">
    <labelfor="someId">{{label || 'Some Input'}}</label>
    <input type="test"id="someId" placeholder="Some Input" [ngModel]="value" (ngModel)="onChange($event)" name="someInput" required #someInput="ngModel" minlength="8"/>
    <spanhttps://www.jb51.cc/tag/Feed/" target="_blank">Feedback" aria-hidden="true" [ngClass]="{'glyphicon-ok': someInput.valid,'glyphicon-remove': someInput.invalid && someInput.dirty}"></span>
    <div [hidden]="someInput.valid || someInput.pristine || !someInput.errors.required">Some Input is required</div>
    <div [hidden]="someInput.valid || someInput.pristine || !someInput.errors.minlength">Some Input must be at least 8 characters</div>
</div>

所以我通过自定义组件实现了以下有关如何在线创建自定义组件的文章：

https://blog.thoughtram.io/angular/2016/07/27/custom-form-controls-in-angular-2.html

缺少的是能够将验证移出组件,但允许自定义组件处理该验证的显示.因此,如果你看一下我的目的是允许组件的用户指定验证而不是让组件强加特定的验证(注意某些验证是组件固有的,例如电子邮件地址组件会验证它是一封没有用户指定的电子邮件).请注意,必需的是该客户组件的使用情况.

那么如何在该组件的定义中获得对自定义组件的FormControl的引用？注意：我理解如何访问模板的FormControl实例中的输入字段,因为上面的代码完全证明了这一点.我要求的是模板所在的自定义控件的FormControl实例.在我引用的文章中,它将是CounterInputComponent的FormControl.

解决方法

添加这似乎工作：

@ViewChild(NgModel) model: NgModel;

然后你可以通过以下方式访问FormControl：

this.model.control

Angular应用里child Component如何向parent Component发送事件

detail Component里，使用event binding，给button click事件注册一个处理函数delete：

<img src="{
    
    
    {itemImageUrl}}" [style.display]="displayNone">
<span [style.text-decoration]="lineThrough">{
  
  
  { item.name }}
</span>
<button (click)="delete()">Delete</button>

@Output() deleteRequest = new EventEmitter<Item>();

delete() {
   
   
   
  this.deleteRequest.emit(this.item);
  this.displayNone = this.displayNone ? '''' : ''none'';
  this.lineThrough = this.lineThrough ? '''' : ''line-through'';
}

在delete函数里，使用EventEmitter发送一个事件。deleteRequest这个property需要加上@Output的注解。

在parent Component里，监听从child Component发送过来的自定义事件：

<app-item-detail (deleteRequest)="deleteItem($event)" [item]="currentItem"></app-item-detail>
