我想用一堆QActions和QMenus覆盖mouseReleaseEvent ...
connect(action1, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
connect(action5, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
connect(action10, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
connect(action25, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
connect(action50, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
所以我想把一个参数传递给插槽onStepIncreased(你可以想象它们是1,5,10,25,50).你知道我怎么做吗？
