[英]Open new BarChart Window (JavaFX) from inside a Swing GUI
當我點擊按鈕(在swing jar應用程序內)時,如何打開新的條形圖窗口(JavaFX)?
我已經有一個帶有按鈕處理程序的GUI功能,但我無法通過按鈕連接Oracle( http://docs.oracle.com/javafx/2/charts/bar-chart.htm )中的示例,以便單擊按鈕時會打開條形圖。
我正在使用桌面Java開發工具包(版本7更新40,64位)和Eclipse Juno。
基本上我試過這個:
...
BarChartSample chart = new BarChartSample();
Stage stage = new Stage();
chart.start(stage);
...
最簡單的方法是用你的搖擺窗口(包含圖表的窗口)來做。
如果你這樣做,代碼看起來像這樣:
JFrame frame = new JFrame("Chart");
final JFXPanel fxPanel = new JFXPanel();
frame.add(fxPanel);
之后你應該將圖表添加到fxPanel,因為javaFx是線程安全的,你將不得不使用Platform.runLater:
Platform.runLater(new Runnable() {
@Override
public void run() {
BarChartSample chart = new BarChartSample();
fxPanel.setScene(new Scene(chart));
}
});
希望能幫助到你!
編輯:
圖表應該是這樣的:
BarChart<String, Number> chart = getChart();
上一行代碼應該在:
Platform.runLater(new Runnable() {
@Override
public void run() {
//CODE HERE
}
});
同樣,這是因為javaFx是線程安全的。
以及創建它的方法:
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;
}
