jframe 里面的 Graphstream small

Question

我正在尝试更改图形流中图形的大小，但它失败了，而且变得越来越小。

这是我的代码。起初，我无法设置 window 标题，所以我唯一的选择是创建一个 JFRAMe 并将视图嵌入其中。所以，如果有设置图表标题的选项，我将不胜感激。

这是我的代码。

public class Clicks implements ViewerListener {
    protected boolean loop = true;

    public static void main(String args[]) throws InterruptedException {
        new Clicks();
    }
    public Clicks() throws InterruptedException {
             System.setProperty("org.graphstream.ui.renderer", "org.graphstream.ui.j2dviewer.J2DGraphRenderer");
        // We do as usual to display a graph. This
        // connect the graph outputs to the viewer.
        // The viewer is a sink of the graph.
        Graph graph = new MultiGraph("Clicks");
                graph.addAttribute("ui.stylesheet", "node#D{ fill-color:red; }node{ stroke-mode: plain;size:20;text-size:30;stroke-color:#333333;text-background-color:#FFF;text-background-mode:plain;text-alignment:above;}");




                Node D = graph.addNode("D");
                Node J = graph.addNode("J");
        Viewer viewer = new Viewer(graph, Viewer.ThreadingModel.GRAPH_IN_ANOTHER_THREAD);
                View view = viewer.addDefaultView(false);


                JFrame frame = new JFrame("title");
                frame.setSize(1000, 1000);
                frame.add((Component) view);
                frame.pack();
                frame.setVisible(true);

                ViewerPipe fromViewer = viewer.newViewerPipe();
        fromViewer.addViewerListener(this);
        fromViewer.addSink(graph);



        while(loop) {
            fromViewer.blockingPump();// or fromViewer.blockingPump(); in the nightly builds
        }
    }

    public void viewClosed(String id) {
        loop = false;
    }

    public void buttonPushed(String id) {

    }

    public void buttonReleased(String id) {
        System.out.println("Button released on node "+id);
    }
}

@edit

即使应用建议的更改，也没有用。

public Clicks() 抛出 InterruptedException { System.setProperty("org.graphstream.ui.renderer", "org.graphstream.ui.j2dviewer.J2DGraphRenderer"); // 我们像往常一样显示图表。这个 // 将图形输出连接到查看器。 // 查看器是图形的接收器。 Graph graph = new MultiGraph("Clicks"); graph.addAttribute("ui.stylesheet", "node#D{ fill-color:red; }node{ stroke-mode: plain;size:20;text-size:30;stroke-color:#333333;text-background-color:#FFF;text-background-mode:plain;text-alignment:above;}");

        Node D = graph.addNode("D");
        Node J = graph.addNode("J");
Viewer viewer = new Viewer(graph, Viewer.ThreadingModel.GRAPH_IN_ANOTHER_THREAD);
        View view = viewer.addDefaultView(false);


        JFrame frame = new JFrame("title");
        frame.add((Component) view);


        ViewerPipe fromViewer = viewer.newViewerPipe();
fromViewer.addViewerListener(this);
fromViewer.addSink(graph);

        frame.pack();
        frame.setVisible(true);


while(loop) {
    fromViewer.blockingPump();// or fromViewer.blockingPump(); in the nightly builds
}

}

当我运行时，window尺寸小，我必须手动调整它。

有什么问题吗？

Answer 1

When i run it, the window size is small, i have to manually resize it.

frame.pack();
frame.setVisible(true);

ViewerPipe fromViewer = viewer.newViewerPipe();
fromViewer.addViewerListener(this);
fromViewer.addSink(graph);

在使框架可见之前，您需要将所有组件添加到框架中。

所以代码应该是：

ViewerPipe fromViewer = viewer.newViewerPipe();
fromViewer.addViewerListener(this);
fromViewer.addSink(graph);

frame.pack();
frame.setVisible(true);

也不需要下面一行：

//frame.setSize(1000, 1000);

pack() 方法将根据添加的所有组件的首选大小重置大小。
