JavaFX 使用 SwingNode 嵌入 JFileChooser 并获取选定的文件
JavaFX embed JFileChooser using SwingNode and get selected file
我已经使用 SwingNode 将 JFileChooser 集成到 JavaFX 应用程序中。该对话框显示并且可用,但我不确定如何从中获取选定的文件。
感谢您的帮助。
@FXML
public void openDialog(MouseEvent event) {
SwingNode swingNode = new SwingNode();
SwingUtilities.invokeLater(() -> {
swingNode.setContent(fileChooser);
});
BorderPane pane = new BorderPane();
pane.setCenter(swingNode);
Stage stage = new Stage();
Scene scene = new Scene(pane, 500, 500);
stage.setScene(scene);
stage.show();
}
出于好奇,我做了一个小例子来做到这一点。
import javafx.application.Application;
import javafx.application.Platform;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javafx.embed.swing.SwingNode;
import javax.swing.JFileChooser;
import javax.swing.SwingUtilities;
public class JunkFx extends Application {
public void openDialog(MouseEvent event) {
JFileChooser fileChooser = new JFileChooser("why");
SwingNode swingNode = new SwingNode();
SwingUtilities.invokeLater(() -> {
swingNode.setContent(fileChooser);
});
BorderPane pane = new BorderPane();
pane.setCenter(swingNode);
Stage stage = new Stage();
Scene scene = new Scene(pane, 500, 500);
stage.setScene(scene);
stage.show();
fileChooser.addActionListener(evt->{
System.out.println(evt.getActionCommand());
System.out.println(fileChooser.getSelectedFile());
Platform.runLater(stage::hide);
});
}
@Override
public void start(Stage stage) throws Exception {
Button b = new Button("click");
b.setOnMouseClicked(this::openDialog);
Scene scene = new Scene(new StackPane(b), 640, 480);
stage.setTitle("open a dialog");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args){
launch(args);
}
}
EDT 上会有一个响应,然后您必须管理如何处理它,检查取消或接受等,然后在平台线程上触发一个操作。
