工作学习 / 专业技术讨论 / Appreciate some help with a Java Swing techniqueI am not a Swing expert, and appreciate some help from an expert.
I want to have two components (fields, labels) to occupy the same location and area on the screen. Under one condition, only component A is visible, and under another conditioin, only component B is visible. But both are there , with only one is visible at a time. Both components contain data from database, even though only one component is visible at a time.
Thanks so much for your help. You are very appreciated!

That is my first thought.But I am a newbie to Swing. (I know web pretty well). Will the invisible and the visible components interfere each other since one is on top of another (adding them to a JPanel has some kind of order, you know. )?
Thanks for answering.

我想不会，你可以 设置一个可见或不可见的同时，设置另一个。
mylabel.setVisible(true/false);
mytextfield.setvisible(!mylabel.isVisible());
如果你有很多控件同时需要可见，另外很多需要不可见.....你可以使用cardLayout

use cardlayout,there is a function some thing like cardlayout.show(componentname);
