当我点击一个按钮(在swing jar应用程序内)时,如何打开一个新的条形图窗口(JavaFX)?
我已经有一个带有按钮处理程序的GUI功能,但我无法将该示例从Oracle(http://docs.oracle.com/javafx/2/charts/bar-chart.htm)与按钮连接,以便在单击按钮时打开条形图。
我正在使用桌面Java开发工具包(版本7更新40,64位)和Eclipse Juno。
基本上我试过这个:
...
BarChartSample chart = new BarChartSample();
Stage stage = new Stage();
chart.start(stage);
...
答案 0 :(得分:1)
最简单的方法是使用摇摆的窗口(包含图表的窗口)来完成。
如果你这样做,代码看起来像这样:
JFrame frame = new JFrame("Chart");
final JFXPanel fxPanel = new JFXPanel();
frame.add(fxPanel);
之后你应该将图表添加到fxPanel,因为javaFx是线程安全的,你将不得不使用Platform.runLater:
Platform.runLater(new Runnable() {
@Override
public void run() {
BarChartSample chart = new BarChartSample();
fxPanel.setScene(new Scene(chart));
}
});
希望它有所帮助!
编辑:
图表应该是这样的:
BarChart<String, Number> chart = getChart();
上一行代码应位于:
Platform.runLater(new Runnable() {
@Override
public void run() {
//CODE HERE
}
});
同样,这是因为javaFx是线程安全的。
以及创建它的方法:
public BarChart<String, Number> getChart() {
final CategoryAxis xAxis = new CategoryAxis();
final NumberAxis yAxis = new NumberAxis();
final BarChart<String, Number> bc = new BarChart<String, Number>(xAxis,
yAxis);
bc.setTitle("Country Summary");
xAxis.setLabel("Country");
yAxis.setLabel("Value");
XYChart.Series series1 = new XYChart.Series();
series1.setName("2003");
series1.getData().add(new XYChart.Data(austria, 25601.34));
series1.getData().add(new XYChart.Data(brazil, 20148.82));
series1.getData().add(new XYChart.Data(france, 10000));
series1.getData().add(new XYChart.Data(italy, 35407.15));
series1.getData().add(new XYChart.Data(usa, 12000));
XYChart.Series series2 = new XYChart.Series();
series2.setName("2004");
series2.getData().add(new XYChart.Data(austria, 57401.85));
series2.getData().add(new XYChart.Data(brazil, 41941.19));
series2.getData().add(new XYChart.Data(france, 45263.37));
series2.getData().add(new XYChart.Data(italy, 117320.16));
series2.getData().add(new XYChart.Data(usa, 14845.27));
XYChart.Series series3 = new XYChart.Series();
series3.setName("2005");
series3.getData().add(new XYChart.Data(austria, 45000.65));
series3.getData().add(new XYChart.Data(brazil, 44835.76));
series3.getData().add(new XYChart.Data(france, 18722.18));
series3.getData().add(new XYChart.Data(italy, 17557.31));
series3.getData().add(new XYChart.Data(usa, 92633.68));
Scene scene = new Scene(bc, 800, 600);
bc.getData().addAll(series1, series2, series3);
return bc;
}
