动画使用的JFrame多个JComponent上 [英] animation with multiple jComponents using jframe
本文介绍了动画使用的JFrame多个JComponent上的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我遇到麻烦的动画在我的花园网格面板的顶部可见。无论我最后补充到contentPane一个节目。反正是有在同一时间，以显示多个组件。我试着开关类动画和花园电网扩展JPanel，但没有奏效。动画是一系列显示一个字符，当你用鼠标拖动运动图像。我需要一个字符在花园网格面板的顶部移动。任何帮助吗？

解决方案
您说明：
我遇到麻烦的动画在我的花园网格面板的顶部可见。无论我最后补充到contentPane一个节目。
一个JFrame的contentPane的使用BorderLayout的，这就是BorderLayouts如何工作。如果您在默认情况下添加组件（没有一个int 2参数），它在默认情况下在BorderLayout.CENTER位置放置，并涵盖任何加到pviously有$ P $。您将要阅读的Swing布局管理器教程在此了解更多详情。
反正是有同时显示多个组件。
是，使用不同的布局管理器和组件。如果你想在彼此顶部组件，可以考虑使用的JLayeredPane。
我已经尝试切换动画类和花园电网扩展JPanel，但没有奏效。动画是一系列显示一个字符，当你用鼠标拖动运动图像。我需要一个字符在花园网格面板的顶部移动。任何帮助吗？
不知道您的具体问题是在这里。
I am having trouble getting the animation visible on top of my garden grid panel. Whichever I add last to the contentpane that one shows. is there anyway to show multiple components at the same time. I've tried switching the classes animation and garden grid to extend jpanel but nothing has worked. Animation is a series of images that shows a character moving when you are dragging it with a mouse. I need that character to move on top of the garden grid panel. any help?

解决方案You state:
I am having trouble getting the animation visible on top of my garden grid panel. Whichever I add last to the contentpane that one shows.
A JFrame's contentPane uses BorderLayout, and that's how BorderLayouts work. If you add a component by default (without an int 2nd parameter), it is placed by default in the BorderLayout.CENTER position and covers anything added there previously. You will want to read the Swing layout manager tutorial for more details on this.
is there anyway to show multiple components at the same time.
Yes, use different layout managers and components. If you want components on top of each other, consider using a JLayeredPane.
I've tried switching the classes animation and garden grid to extend jpanel but nothing has worked. Animation is a series of images that shows a character moving when you are dragging it with a mouse. I need that character to move on top of the garden grid panel. any help?
