我正在尝试更改图形流内部图形的大小,但它的失败甚至变小。
这是我的代码。起初,我无法设置窗口标题,所以我唯一的选择是创建一个JFRAMe并将视图嵌入其中。所以,如果有一个选项来设置图表的标题,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
即使应用所提出的更改,它也无效。
public Clicks()抛出InterruptedException { System.setProperty(“org.graphstream.ui.renderer”,“org.graphstream.ui.j2dviewer.J2DGraphRenderer”); //我们照常显示图表。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 - 颜色:#FFF;文本背景模式:平纹;文本对齐:上面;}“);
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);

当我运行它时,窗口大小很小,我必须手动调整它的大小。
问题是什么?

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);
此外,不需要以下一行:
//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。
