[英]cellClicked and cellPressed not working for QTableWidget
Whats is wrong with following call.以下电话有什么问题。 IDBTable is QTableWidget
IDBTable 是 QTableWidget
connect(m_GUI->m_UI->IDBTable,SIGNAL(cellPressed(2, 0)), this, SLOT(slotGoToWelcomeScreen()));
Your signal definition is wrong.你的信号定义是错误的。 There is no such signal
cellPressed(2, 0)
but only cellPressed(int, int)
.没有这样的信号
cellPressed(2, 0)
而只有cellPressed(int, int)
。 Please read the documentation about signals and slots and prefer the new signal slot syntax to catch such errors during compile time.请阅读有关信号和槽的文档,并更喜欢新的信号槽语法以在编译时捕获此类错误。
