如何拖动JavaFX的未修饰窗口(阶段) [英] How to drag an undecorated window (stage) of JavaFX
本文介绍了如何拖动JavaFX的未修饰窗口(阶段)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有这个未装饰的窗口:
I have this undecorated window:
public static void initStartPage(final Stage primaryStage) {
final Stage startPage = new Stage();
startPage.initStyle(StageStyle.UNDECORATED);
//startPage.initOwner(primaryStage);
//startPage.toFront();
Scene scene = new Scene(agentsPanel(), 900, 500);
startPage.setScene(scene);
startPage.show();
}
我想知道如何将其设置为可拖动的未装饰窗口? 当用户使用鼠标右键选择窗口,然后在按住鼠标按钮的同时移动鼠标时,我想更改其位置.
I would like to know how I can make it a draggable undecorated window? I want to change its position when the user selects the window with the right mouse button and then move the mouse while keeping the mouse button pressed down.
P.S.我测试了此解决方案,但是它不起作用:
P.S. I tested this solution, but it's not working:
private static FlowPane flow;
private static BorderPane bpi;
public static void initStartPage(final Stage primaryStage) {
final Stage startPage = new Stage();
startPage.initStyle(StageStyle.UNDECORATED);
startPage.initOwner(primaryStage);
//startPage.toFront();
Scene scene = new Scene(agentsPanel(primaryStage), 900, 500);
startPage.setScene(scene);
startPage.show();
}
private static double xOffset = 0;
private static double yOffset = 0;
public static BorderPane agentsPanel(final Stage primaryStage) {
BorderPane bp = new BorderPane();
bp.setPrefSize(900, 500);
bp.setMaxSize(900, 500);
HBox thb = new HBox(10); // Set spacing between each child into the HBox
thb.setPadding(new Insets(15, 15, 15, 15));
HBox bhb = new HBox(10); // Set spacing between each child into the HBox
bhb.setPadding(new Insets(15, 15, 15, 15));
bp.setTop(thb);
bp.setBottom(bhb);
bp.setCenter(navigationPanel());
bp.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
xOffset = event.getSceneX();
yOffset = event.getSceneY();
}
});
bp.setOnMouseDragged(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
primaryStage.setX(event.getScreenX() - xOffset);
primaryStage.setY(event.getScreenY() - yOffset);
}
});
return bp;
}
推荐答案
只需将setOnMousePressed方法更改为此:
Just change your setOnMousePressed method to this:
bp.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
xOffset = primaryStage.getX() - event.getScreenX();
yOffset = primaryStage.getY() - event.getScreenY();
}
});
和您的setOnMouse拖到了这里:
and your setOnMouseDragged to this:
bp.setOnMouseDragged(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
primaryStage.setX(event.getScreenX() + xOffset);
primaryStage.setY(event.getScreenY() + yOffset);
}
});
