在GridBagLayout中动态更改组件权重 [英] Change the component weight dynamically in GridBagLayout

问题描述

假设现在JPanel中有一些组件，并且使用GridBagLayout安排了布局.是否可以动态更改组件的权重(权重或权重)(例如，按下按钮后)?谢谢.

Suppose now there are some components inside a JPanel and the layout is arranged using GridBagLayout. Is it possible to change the weight(weightx or weighty) of the components dynamically (e.g. after pressing a button)? Thank you.

推荐答案

使用新的GridBagConstraint删除并添加组件.通话结束后

Remove and add the component with a new GridBagConstraint. After that call

panel.revalidate();
panel.repaint();

使用该方法获取当前约束公共GridBagConstraints getConstraints(Component comp)

Use the method to get current constraints public GridBagConstraints getConstraints(Component comp)
