单击JTabbedPane上的选项卡时，组件不会立即显示

Question

I have an application that includes a JTabbedPane and two tabs with some components. My problem is when I click on another tab, it's components do not appear immediately; but when the mouse courser moves over each component ( JCheckBox , JButton and so on) of the tab, the components will appear but not correctly (see below image).

This is my CODE . . .

Answer 1

Are you mixing some awt and swing stuff?

This could probably make such unpredictable effects.

Answer 2

Can you see an exception on the console? Exceptions in Event Dispatching Thread can cause such behavior.

Answer 3

As others have observed, your code is incomplete. As a guide, consider this article on the benefits of a Short, Self Contained, Correct (Compilable), Example . Several such examples are discussed in How to Use Tabbed Panes . You might compare them with what you're doing.

Answer 4

感谢你的响应，问题是调用一个组件的repaint（），当我改变它的位置时，标记的位置必须在用户每次移动或页面事件发生时改变，所以我认为调用重绘（ ）导致循环和其他组件没有正确绘制。
