Swing-未调用paintComponent方法（尚未调用beginbuild）

我只是实现了继承JPanel的类，如下所示

public class Orpanel extends JPanel {....    @Override    public void paintComponent(Graphics g) {        super.paintComponent(g);        Graphics2D g2d = (Graphics2D)g;        g2d.setPaint(tpaint);        g2d.fill(rect);     }....}

Orpanel类正在加载图像并调整其自身大小。

这是问题。

调用JFrame的setContentpane（Orpanel的实例）使其工作正常，但是当我将Orpanel附加到JFrame时，调用add（）方法而不是setContentpane（我知道setcontentpane并不意味着attach
..反正），它就行不通了。

终于弄清楚了当我使用add（）方法时，添加到JFrame的Component不会调用paintComponent（）方法。即使我手动调用repaint（）方法，仍然不会调用paintComponent（）方法。

我错过了什么？任何帮助将不胜感激！

提前。海永信

我添加了额外的代码。

public Test(OwPanel op) {    super();    Dimension monitor = Toolkit.getDefaultToolkit().getScreenSize();    op.setBackground(Color.white);    this.setBackground(Color.white);            this.setBounds(monitor.width / 2 - 200 , monitor.height / 2 - 200, 400, 400);           this.setDefaultCloseOperation(EXIT_ON_CLOSE);    this.setTitle("test");          this.setLayout(null);    this.getContentPane().add(op);    //this.setContentPane(op);    this.setVisible(true);    this.validate();}    public static void main(String[] args) {    // TODO Auto-generated method stub    SwingUtilities.invokeLater(new Runnable() {        @Override        public void run() {            OwPanel op = new OwPanel("d:\\java_workplace\\img\\img1.jpg", 100, 100);            OwLabel ol = new OwLabel("d:\\java_workplace\\img\\img2.jpg", 300, 50);            Test tst =  new Test(op);            tst.add(ol);        }    });

如果将setContentpane（）方法替换为getContentpane（）。add（），仍然无法正常工作。不要困惑。Owpanel和Orpanel相同：)

小编典典

在您的示例代码中，我看到您选择不使用LayoutManager，这是一个非常糟糕的主意，但是无论如何，按照这种方式，我看到了一个Orpanel.paintComponent()不被调用的原因：它可能在框架内不可见！

如果没有LayoutManager，则必须（通过setBounds()）显式设置添加到框架的所有组件的大小和位置。

您可能没有这样做，因此Orpanel实例的大小可能为0，因此它永远不会被绘制。

Angular 2：ngSwitch或ViewContainerRef.createComponent

我有一个案例,我在列表中动态创建组件(刷新很多)并使用像这样的ngSwitch：

<div *ngFor='let item of items'>
   <div [ngSwitch]="item.view">
        <view-one *ngSwitchCase="'one'"></view-one>
        <view-two *ngSwitchCase="'two'"></view-two>
        <view-three *ngSwitchCase="'three'"></view-three>
    </div>
</div>

我想知道是否有更好的更有效的方法,或者这是正确的方法吗？

我见过人们动态创建组件,但api已经改变了很多次,很难知道什么是正确的.似乎ViewContainerRef.createComponent()可能是另一种选择？

解决方法

我更喜欢createComponent()而不是ngSwitch,因为我认为它更容易测试和扩展.我还没有看到任何表现不足.

这是我当前方法的简化形式：

@Component({
    selector: "my-item",template: `
        <div #placeholder></div>
    `
})
export class MyItemComponent implements AfterViewInit {
    @input() item: any;
    @ViewChild("placeholder",{read: ViewContainerRef}) placeholderRef: ViewContainerRef;

    constructor(
        private componentFactoryResolver: ComponentFactoryResolver) {
    }

    ngAfterViewInit() {
        switch(this.item.view) {
            case "one":
                this.loadItem(OneItemComponent);
            case "two":
                this.loadItem(TwoItemComponent);
            default:
                throw new Error("UnkNown item!");
        }
    }

    private loadItem(component: Type<any>) {
        const factory = this.componentFactoryResolver.resolveComponentFactory(component);
        const componentRef = this.placeholderRef.createComponent(factory);
        componentRef.instance.item = this.item;
        componentRef.changeDetectorRef.detectChanges();
    }
}

现在您可以通过以下方式使用它：

<my-item *ngFor="let item of items" [item]="item"></my-item>
