Question

我在下面编写了一个测试类，但我无法将其添加到com.smartgwt.client.widgets.Window中。

任何人都可以帮我这个吗？提前谢谢！

package com.smartgwt.sample.showcase.client;

import pl.tecna.gwt.connectors.client.ConnectionPoint; import pl.tecna.gwt.connectors.client.Connector; import pl.tecna.gwt.connectors.client.Diagram; import pl.tecna.gwt.connectors.client.SectionDecoration; import pl.tecna.gwt.connectors.client.Shape;

import com.google.gwt.user.client.ui.AbsolutePanel; import com.google.gwt.user.client.ui.Composite; import com.google.gwt.user.client.ui.Image; import com.smartgwt.client.widgets.Label;

公共类NetworkMap {

public NetworkMap（）{ AbsolutePanel widget = new AbsolutePanel（）;

    final Diagram diagram = new Diagram(widget);

    final Label label = new Label("LABEL");

最终图片图片=新图片（“http://code.google.com/images/code_sm.png”）; image.setPixelSize（153,55）;

widget.add（label，50,250）; widget.add（image，200,300）;

Shape shapeForLabel = new Shape（label）; shapeForLabel.showOnDiagram（图）;

Shape shapeForImage = new Shape（image）; shapeForImage.showOnDiagram（图）;

ConnectionPoint labelConnectionPoint = shapeForLabel.connectionPoints [Shape.E]; ConnectionPoint imageConnectionPoint = shapeForImage.connectionPoints [Shape.W];

 Connector label2image = new Connector
     (labelConnectionPoint.getAbsoluteLeft(),
                  labelConnectionPoint.getAbsoluteTop(),
                  imageConnectionPoint.getAbsoluteLeft(),
                  imageConnectionPoint.getAbsoluteTop(),
                  null,
                  new SectionDecoration(SectionDecoration.DECORATE_ARROW));

 label2image.startEndPoint.glueToConnectionPoint(labelConnectionPoint);
 label2image.endEndPoint.glueToConnectionPoint(imageConnectionPoint);

 label2image.showOnDiagram(diagram);  
    /* // Create boundary panel

AbsolutePanel boundaryPanel = new AbsolutePanel（）;

initWidget（boundaryPanel）; boundaryPanel.setSize（“700px”，“700px”）; RootPanel.get（）。add（boundaryPanel，10,10）;

final Diagram diagram = new Diagram（boundaryPanel）;

boundaryPanel.add（new Label（“GWT 1.7的连接器示例”），10,2）;

//添加一些可以连接的元素最终标签标签=新标签（“LABEL”）; 最终图像图像=新图像（“http://code.google.com/images/code_sm.png”）; image.setPixelSize（153,55）;

boundaryPanel.add（label，50,250）; boundaryPanel.add（image，200,300）;

Shape shapeForLabel = new Shape（label）; shapeForLabel.showOnDiagram（图）;

Shape shapeForImage = new Shape（image）; shapeForImage.showOnDiagram（图）;

//连接标签和图片 ConnectionPoint labelConnectionPoint = shapeForLabel.connectionPoints [Shape.E]; ConnectionPoint imageConnectionPoint = shapeForImage.connectionPoints [Shape.W];

 Connector label2image = new Connector
     (labelConnectionPoint.getAbsoluteLeft(),
                  labelConnectionPoint.getAbsoluteTop(),
                  imageConnectionPoint.getAbsoluteLeft(),
                  imageConnectionPoint.getAbsoluteTop(),
                  null,
                  new SectionDecoration(SectionDecoration.DECORATE_ARROW));

 label2image.startEndPoint.glueToConnectionPoint(labelConnectionPoint);
 label2image.endEndPoint.glueToConnectionPoint(imageConnectionPoint);

 label2image.showOnDiagram(diagram);

据我所知，您正在尝试将NetworkMap放入Window小部件中。 NetworkMap类需要实现Composite接口，以便将其视为窗口小部件并显示在Window，Panel等中......一旦实现了Composite接口，您需要通过提供主面板调用initWidget（）函数/在您的NetworkMap类中包含您的小部件的布局（您已完成此操作）。因此你需要写;

public class NetworkMap extends Composite { ... }

将gwt-connectors添加到smartgwt中
