实现 JavaFX 无边框可拖拽移动窗口

JavaFX borderless

原文链接: Making a borderless JAVAFX Window Movable

Step 1

Go to your Main class of your project and set your stage to be UNDERDECORATED or TRANSPARENT.

stage.initStyle(StageStyle.UNDECORATED);

Step 2

The next thing you want to do is initialize two doubles for the x and y screen offsets;

private double xOffset = 0; 
private double yOffset = 0;

Step 3

Add mouse events to your root, i.e your FXML loader and you are ready to “move”

// Parent root = FXMLLoader.load(getClass().getResource("login.fxml"));
root.setOnMousePressed(event -> {
    xOffSet = event.getSceneX();
    yOffSet = event.getSceneY();
});

root.setOnMouseDragged(event -> {
    stage.setX(event.getScreenX() - xOffSet);
    stage.setY(event.getScreenY() - yOffSet);
});
