QQ好友列表树形列表java代码实现代码
以前在网上瞎转悠的时候就发现很多人为用java实现QQ登陆后的面板的问题感到十分头疼,最近我因在写模拟QQ的项目,故不可或缺的遇到了这一个问题,在网上我google了,百度了,最终发现的是有很多人被这一问题困扰,却没有解决的方案,估计是那些写出来了的人,没有发布到网上来,如今,经过自己的多方面查找资料,终于把他写出来了,也不枉昨晚熬夜了,呵呵,好了先让我们来看看实现的效果截图:
好了,效果就是这样了,虽然实现了基本功能,但是还是不完美,比如说好友面板不能随着窗口改变大小而改变,不过应该已经可以解决了,只是还没实践,下面就发上源代码:
一共有三个类:
MemberModel.java //显示类QQ似好友标签信息的模板类;
TestPane.java //添加多个模板的容器类;
TestFrame.java //窗体类;
核心部分是前面两个类,注意,第二个类的布局方式不能为空,否则不能是容器显示滚动条,这是实现这个面板功能的一个难题,因为我不怎么会使用其他的布局方式,就只经常用空布局,经过这次才知道,光用空布局是不行的,空布局的应用受到了太多的限制。
在TestPane.java中添加好友信息的方式应该是代码添加黑名单信息的方式,可在其他类中调用方法,传递参数(数组)过来,然后对信息模板进行初始化,还有面板上的信息模板从程序刚开始运行就生成了,只是设置了不可见,后点击相关分类标签后的可视与不可视是同理的,也就是说你有多少个好友就一直会有多少个JLabel存在你的面板上,只是你可能看不见他们,我感觉自己的实现方式不是很好。还有在我所用的这种布局方式中,显示Label的宽度是一定的,我不知道怎么设置他的宽度和高度,所以通过在Label上添加了一个白色图标(185 X 60)来使Label变宽,然后再添加模板JPanel,如果网友们还有好的解决方法,希望不吝赐教。
下面是源码:
