请问 怎样获取 产生事件的对象的信息？fjb [复制链接]

比如： 单击了一个按钮，我想在处理函数中 得到 这个按钮的 名字 文本。。

谢！

比如：
QPushButton *button = qobject_cast<QPushButton *>(sender());
QString text = button->text();

QObject * QObject::sender () const  [protected]
Returns a pointer to the object that sent the signal, if called in a slot activated by a signal; otherwise it returns 0. The pointer is valid only during the execution of the slot that calls this function.
The pointer returned by this function becomes invalid if the sender is destroyed, or if the slot is disconnected from the sender's signal.
Warning: This function violates the object-oriented principle of modularity. However, getting access to the sender might be useful when many signals are connected to a single slot.
