将参数传递到插槽
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())); 因此，我想将参数传递给广告位onStepIncreased（您可以想象它们是1,5,10,25,50）。你知道我该怎么做吗？
