自己写了个随机抽签器
本帖最后由 meilon 于 2017-6-18 21:24 编辑本来是老师想要个随机点名器, 上网上找了半天, 没一个满意的, 干脆自己捣腾着做了一个.
界面比较简单,不过使用还是比较方便的.
说明:
document.txt 中添加/删除 抽签的条目, 每行一个条目,可输入数字作为随机抽奖器用, 也可输入人名当随机点名器用.
propert.ini 可修改配置
fontFamily : 设置字体
fontSize : 设置字体大小(20~100)
fontWeight : 设置字体粗细(0~1), 默认0
width : 设置窗口宽度(600~MAX), 默认600, MAX屏幕大小
height : 设置窗口高度(400~MAX), 默认400
amortize : 设置缓冲次数(1~30), 默认25
贴上源码, 求大神指点
这是读取配置的

} 请问一下楼主如何使用？没有exe啊。。。 萌萌哒、merry 发表于 2017-6-18 21:41
大兄弟，作弊不是好同学啊
哈哈 没办法啊 企业抽奖一般都是暗箱操作啊 没办法 楼主有可以操作的吗 收到 感谢楼主 请问可以设置预先操作吗 就是设定一个人 抽奖时一定能抽中的 peterq521 发表于 2017-6-18 21:35

没设置这功能, 得改源码... 谢谢楼主分享！下来学习！
谢谢楼主分享！ 谢谢楼主提供，看一下。{:1_919:}
