我正在嘗試將焦點(diǎn)設(shè)置在 JTextPane 上，以便在窗口打開時(shí)可以立即使用鍵盤進(jìn)行編輯。但是，我所做的一切似乎都沒有讓 JTextPane 專注于啟動。這只是將 JavaFX 與 Swing 結(jié)合使用的問題嗎？import javafx.collections.FXCollections;import javafx.collections.ObservableList;import javafx.embed.swing.SwingNode;import javafx.event.ActionEvent;import javafx.fxml.FXML;import javafx.scene.control.ListView;import javax.swing.*;public class TestDialog { @FXML private ListView listView; @FXML private SwingNode node; private ObservableList<Integer> obsList; @FXML public void initialize(){ JTextPane pane = new JTextPane(); SwingUtilities.invokeLater(() -> pane.requestFocusInWindow()); pane.setText("This issue is not reproducible in JDK 8 early-access build (8u172) which is yet to be released."); node.setContent(pane); obsList = FXCollections.observableArrayList(); for(int x = 0; x < 12; x++){ obsList.add(x); } listView.setItems(obsList); node.setFocusTraversable(true); node.requestFocus(); pane.requestFocus(); pane.grabFocus(); } @FXML private void removeItem(ActionEvent event) { obsList.remove(0); }}

我不知道這是否有幫助，但下面是我根據(jù)示例代碼制作的演示程序，出于某種原因，它對我有用：
import javafx.application.Application;
import javafx.application.Platform;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.embed.swing.SwingNode;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.Scene;
import javafx.scene.control.ListView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javax.swing.*;
public class Test extends Application {
@FXML
private ListView listView;
@FXML
private SwingNode node;
private ObservableList<Integer> obsList;
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage arg0) throws Exception {
initialize(arg0);
}
@FXML
public void initialize(Stage stage){
JTextPane pane = new JTextPane();
// The program runs the same no matter if one of the below two lines are used or if neither are used
//SwingUtilities.invokeLater(() -> pane.requestFocusInWindow());
//Platform.runLater(() -> {node.requestFocus();});
pane.setText("This issue is not reproducible in JDK 8 early-access build (8u172) which is yet to be released.");
node = new SwingNode();
node.setContent(pane);
obsList = FXCollections.observableArrayList();
for(int x = 0; x < 12; x++){
obsList.add(x);
}
listView = new ListView();
listView.setItems(obsList);
node.setFocusTraversable(true);
node.requestFocus();
pane.requestFocus();
pane.grabFocus();
StackPane root = new StackPane();
root.getChildren().add(node);
Scene scene = new Scene(root, 500, 500);
stage.setTitle("Test");
stage.setScene(scene);
stage.show();
}
@FXML
private void removeItem(ActionEvent event) {
obsList.remove(0);
}
}
