JavaFx窗格按钮位置 [英] JavaFx Pane Button position

问题描述

作为布局，我有一个Pane. 更改窗口大小后，如何始终将按钮的位置设置在右角?

As a layout I have a Pane. How do I set the position of a button always in the right corner when windows size is changed?

Pane root = new Pane();

Button b = new Button("Button ");

b.setLayoutX(100);
b.setLayoutY(0);
root.getChildren().add(b);

推荐答案

Pane不适用于这种布局.您可以使用

Pane is not a good fit for this kind of layout. You could use

• StackPane:这将使每个子项与角，边的中心或中心对齐.

• StackPane: This will align every single child to a corner, center of an edge or the center though.

AnchorPane:默认情况下，此布局与Pane相同，但是如果设置锚点，则可以设置子项到顶部，左侧，右侧和/或底部的距离.

AnchorPane: By default this layout works the same as Pane, but if you set anchors, you can set the distance of a child from the top, left, right and/or bottom.

示例:

AnchorPane root = new AnchorPane();

Button b = new Button("Button ");

// place button in the top right corner
AnchorPane.setRightAnchor(b, 0d); // distance 0 from right side of 
AnchorPane.setTopAnchor(b, 0d); // distance 0 from top

root.getChildren().add(b);
