我相信我發現了一個BorderPane的bug。如果您不旋轉手機,舞臺將按預期關閉。但是,如果旋轉手機,然後單擊關閉,則屏幕將不執行任何操作,直到您將手機旋轉回原始位置,然後顯示primaryStage。重新創建它的代碼非常簡單。手機旋轉90度後舞臺不會關閉BorderPane
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.FlowPane;
import javafx.stage.Modality;
import javafx.stage.Screen;
import javafx.stage.Stage;
public class HelloWorld extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Hello World!");
Button btn = new Button();
btn.setText("Say 'Hello World'");
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
final Stage stage = new Stage();
Button closeBtn = new Button("Close");
closeBtn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
stage.close();
}
});
FlowPane pane = new FlowPane();
pane.getChildren().addAll(new Label("Hello World!"), closeBtn);
Scene scene = new Scene(pane);
stage.initModality(Modality.APPLICATION_MODAL);
stage.initOwner(primaryStage);
stage.setScene(scene);
stage.show();
}
});
BorderPane borderPane = new BorderPane();
borderPane.setPrefHeight(Screen.getPrimary().getVisualBounds().getMaxY());
borderPane.setPrefWidth(Screen.getPrimary().getVisualBounds().getMaxX());
borderPane.setCenter(btn);
primaryStage.setScene(new Scene(borderPane));
primaryStage.show();
}
有沒有人知道如何解決這個問題?
的build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.javafxports:jfxmobile-plugin:1.0.8'
}
}
apply plugin: 'org.javafxports.jfxmobile'
mainClassName = 'helloworld.HelloWorld'
version = '8u40'
repositories {
mavenLocal()
mavenCentral()
jcenter()
}
jfxmobile {
ios {
forceLinkClasses = ['ensemble.**.*']
}
android {
applicationPackage = 'org.javafxports.ensemble'
}
}
謝謝你的提示。我刪除了額外的舞臺和場景。我的解決方法是這樣的。
package helloworld;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.FlowPane;
import javafx.stage.Screen;
import javafx.stage.Stage;
public class HelloWorld extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Hello World!");
final Group group = new Group();
final BorderPane borderPane = new BorderPane();
borderPane.setPrefHeight(Screen.getPrimary().getVisualBounds().getMaxY());
borderPane.setPrefWidth(Screen.getPrimary().getVisualBounds().getMaxX());
final Button btn = new Button("Say 'Hello World'");
borderPane.setCenter(btn);
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
Button closeBtn = new Button("Close");
closeBtn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
group.getChildren().setAll(borderPane);
}
});
FlowPane pane = new FlowPane();
pane.getChildren().addAll(new Label("Hello World!"), closeBtn);
group.getChildren().setAll(pane);
}
});
group.getChildren().add(borderPane);
primaryStage.setScene(new Scene(group));
primaryStage.show();
}
}
什麼手機?你可能想提供一些關於你如何測試它的更多信息。無論問題是什麼,在你提出的問題中,似乎都不太可能成爲BorderPane中的一個bug。 – jewelsea
