Qt制作鸡你太美鬼畜桌面小工具

作为一名成熟的ikun，守护坤坤是我的使命，同时，作为一名程序员，总觉得需要做点什么来对表达对坤坤的仰慕之情。

于是，我利用Qt制作了一个守护坤坤的桌面小工具，它可以根据键盘上的 'j' 'n' 't' 'm' 'ctrl + c' 'ctrl + t' 'ctrl + r' 'ctrl + l'  "  "，等按键发出鸡、你、太、美、唱、跳、rap、篮球、你干嘛的音效，并伴随文字显示，同时支持桌面拖动与系统托盘图标显示；

         

 

 

 源码如下：

程序中使用了 QSystemTrayIcon、QAction、QMenu 对窗口进行托盘图标设置，QMouseEvent对鼠标按下、双击、托动、松开等状态进行事件处理，QPainter对ikun图片进行绘制，QSound对音频进行播放，QKeyEvent对键盘按键事件进行处理，QTimer对文字气泡显示时间定时，QLabel对文字进行展示；
