資源簡介

Qt 多線程及簡單實例 demo。 多線程的幾大特點: 1.多線程的執(zhí)行順序無法保證,與操作系統(tǒng)的調度策略和線程優(yōu)先級等因素有關。 2.多線程的切換可能發(fā)生在任何時刻、任何地點。 3.多線程對代碼的敏感度高,因此對代碼的細微修改都可能產(chǎn)生意想不到的效果。 先由一個簡單的例子引出多線程 先作出這個簡單的界面 “開始”對應的槽函數(shù)是:slotStart() “停止”對應的槽函數(shù)是:slotStop() 本例中的線程(workthread類)實現(xiàn)的功能是,從0到9循環(huán)打印,0至9各占一排。 則該線程的具體實現(xiàn)詳見demo。 demo環(huán)境為qt5.9 64位
