Electron Windows增加托盘悬浮框功能
背景
在做Electron Windows 桌面应用时候,做鼠标悬浮到托盘图标上时显示一个悬浮框(例如做消息提醒),但因为Windows没有提供托盘mouse-enter/mouse-leave事件,无法直接做这个功能,考虑到还有mouse-move事件,弄个间接的方式实现。
实现步骤
1、监听mouse-move事件,当触发时,即也相当触发mouse-enter事件。
2、开始定时(100ms)获取托盘位置和鼠标位置,判断鼠标是否还在托盘图标里,当已不在时,触发mouse-leave事件并停止定时查询。
//判断鼠标是否还在托盘图标trayBounds = tray.getBounds(); point = screen.getCursorScreenPoint(); if(!(trayBounds.x < point.x && trayBounds.y < point.y && point.x < (trayBounds.x + trayBounds.width) && point.y < (trayBounds.y + trayBounds.height))){ //已不在托盘,触发mouse-leave }
3、当mouse-enter时,显示悬浮窗口到托盘上方,当mouse-enter,隐藏悬浮窗口。
PS:悬浮窗口需要设置置顶属性,且不显示在任务栏。
具体代码
var leaveInter, trayBounds, point, isLeave = true; function checkTrayLeave(){ clearInterval(leaveInter) leaveInter = setInterval(function(){ trayBounds = tray.getBounds(); point = screen.getCursorScreenPoint(); if(!(trayBounds.x < point.x && trayBounds.y < point.y && point.x < (trayBounds.x + trayBounds.width) && point.y < (trayBounds.y + trayBounds.height))){ //触发mouse-leave clearInterval(leaveInter); isLeave = true; } }, 100) } tray.on(‘mouse-move‘, () => { if (isLeave) { //触发mouse-enter isLeave = false; checkTrayLeave(); } })
