QAction *cancelBadAction = new QAction(this);
QKeySequence cancelBadSequence(Qt::Key_Escape);煎锅贴
cancelBadAction->tShortcut(cancelBadSequence);
this->addAction(cancelBadAction); //把这个QAction的对象加⼊到当前窗⼝中去.
evdo//连接信号与槽，当你按下ESC时，就会调⽤槽函数
connect(cancelBadAction,SIGNAL(triggered()),badPixelTab, SLOT(cancelOneBadBtn_clicked())); QAction *upAction = new QAction(this);
QKeySequence upSequence(Qt::CTRL + Qt::Key_W);
upAction->tShortcut(upSequence);
this->addAction(upAction);
