千里冰封
JAVA 浓香四溢

昨天看到留言,于是今天又把一些功能加进进去了

比如,
1,程序可以最小化到系统托盘区
2,程序可以批量保存所有截过的图片
3,修正了以前的一个小BUG,那就是输入保存图片的文件名时,如果没有输入后缀名,将保存正常,如果输入了后缀名,将会保存格式出错
打包文件请点击这里下载,dist文件夹里面的JAR文件是可以双击执行的

感谢朋友们的建议,谢谢.

支持, 只不过可能只能运行在 JDK 1.6 了, 因为用了托盘.  回复  更多评论

@BeanSoft
呵呵,那也是,必须要有所取舍
并且下载一个JDK6.0也不是很难的事了
不过,除掉托盘的代码,JDK5.0也是一样可以运行的  回复  更多评论

动作挺快! 不过有几个地方需要修正。

1、在最小化的时候,建议先让用户设置一下最小化的处理方式(托盘区或者任务栏),2者最好不要同时存在,因为最小化到任务栏,放在托盘区就没有任何意义了。

2、关于托盘区的使用,请参看一下TM的使用方式。  回复  更多评论

@Samuel
呵呵,多谢建议
程序一开启就在托盘区. 最小化的时候依然在任务栏
并不是不想改了,主要是再改的话,还要加菜单给用户设置,
所以得做一个取舍,只有去掉设置,而让面板更易用了  回复  更多评论

程序固然是完成了计划的功能。但是把它连续截屏20或30次以上,就会报:
java.lang.内存溢出错误,不信可以试一下。
N试不爽。如果用在聊天程序中,连截几次图,就悲剧了。
希望楼主测试修正一下内存问题。
