我寫了一個程式:
class ScribbleWindow : public QListWidget
{
Q_OBJECT
...........
};
ScribbleWindow::ScribbleWindow()
{
QListWidgetItem *testitem = new QListWidgetItem(QIcon(":/images/ft_folder_big.xpm"), "test",this,0);
connect(this,SIGNAL(itemDoubleClicked(penWidthitem)),this,SLOT(penWidth()));
}
發生錯誤:
Object::connect: No such signal ScribbleWindow::itemDoubleClicked(penWidthitem)
請問一下是不能這樣用嗎??
那要如何才能實現??
又有關創建signal的文件要那裡找??
