java - GXT : destroying Dialogbox didn't work

Question

我有一个对话框类:

public class Dialogbox {

    public static final Window dialogbox = new Window();

    public Dialogbox() {
        dialogbox.setAnimateMinimize(true);

        dialogbox.setWidth(469);
        dialogbox.setHeight(487);
        dialogbox.setShowMinimizeButton(true);
        dialogbox.setAutoSize(true);
        dialogbox.setCanDragReposition(true);
        dialogbox.setCanDragResize(true);
        dialogbox.setIsModal(true);
        // dialogbox.setShowModalMask(true);
        dialogbox.addCloseClickHandler(new CloseClickHandler() {
            @Override
            public void onCloseClick(CloseClientEvent event) {
                // TODO Auto-generated method stub
                dialogbox.destroy();
            }
        });

    }

    public void show(Widget name, String txt) {
        dialogbox.setTitle(txt);
        dialogbox.addItem(name);
        dialogbox.setPadding(10);
        AnimationCallback callback = null;
        dialogbox.animateMove(400, 100, callback, 1000);


        dialogbox.show();

    }

当我尝试复合时:

f list = new f();
dia.show(f, "price");

我收到错误:

[ERROR] 15:34:20.020:WARN:Canvas:isc_WidgetCanvas_1:Attempt to access destroyed widget in the DOM - destroy() called at invalid time (eg: mid-draw) or invalid method called on destroy()d widget. Stack Trace:

我的内置合成器是一个小部件:

    Canvas canvas = new Canvas();
    canvas.addChild(btnNewButton);
    initWidget(canvas);

为什么我不能销毁我的对话框？我必须先删除该小部件吗？

是的，如果您只想隐藏对话框，那么你可以使用 dialogbox.hide()如果您想删除对话框，然后您可以使用

将其从父元素中分离/删除

dialogbox.removeFromParent()

但是，正如我所期望的，您只想隐藏对话框。

这里我给出了两种方式，大家可以根据自己的需求来使用。
