我在手册或SO中找不到答案。我想用JGraphX制作一个显示一些顶点和边缘的图形,但是我不希望用户能够移动任何东西,也不希望这些绿色的编辑框出现在涡旋或边缘上。它仅用于显示。
我尝试对“Hello World”示例进行的这种修改无济于事。有什么建议么?
package com.mxgraph.examples.swing;
import java.util.Hashtable;
import javax.swing.JFrame;
import com.mxgraph.swing.mxGraphComponent;
import com.mxgraph.util.mxConstants;
import com.mxgraph.view.mxGraph;
import com.mxgraph.view.mxStylesheet;
public class HelloWorld extends JFrame
{
/**
*
*/
private static final long serialVersionUID = -2707712944901661771L;
public HelloWorld()
{
super("Hello, World!");
mxGraph graph = new mxGraph();
Object parent = graph.getDefaultParent();
//my addition of a stylesheet, I used it on the first node to see if it mad
//a difference, it didn't regarding dragability//////////////////////////////
mxStylesheet stylesheet = graph.getStylesheet();
Hashtable<String, Object> style = new Hashtable<String, Object>();
style.put(mxConstants.STYLE_SHAPE, mxConstants.SHAPE_ELLIPSE);
style.put(mxConstants.STYLE_OPACITY, 50);
style.put(mxConstants.STYLE_FONTCOLOR, "#774400");
style.put(mxConstants.STYLE_EDITABLE, false);
stylesheet.putCellStyle("ROUNDED", style);
//tried this too///////////////////////////////////////////////
graph.setCellsEditable(false);
graph.getModel().beginUpdate();
try
{
Object v1 = graph.insertVertex(parent, null, "Hello", 20, 20, 80,
30, "ROUNDED");
Object v2 = graph.insertVertex(parent, null, "World!", 240, 150,
80, 30);
graph.insertEdge(parent, null, "Edge", v1, v2);
}
finally
{
graph.getModel().endUpdate();
}
mxGraphComponent graphComponent = new mxGraphComponent(graph);
getContentPane().add(graphComponent);
}
public static void main(String[] args)
{
HelloWorld frame = new HelloWorld();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(400, 320);
frame.setVisible(true);
}
}
最佳答案
您可以禁用整个图形组件mxGraphComponent
:
graphComponent.setEnabled(false);
关于java - JGraphX-希望整个图形不可编辑,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/19847637/
