我创建了一个QPushButton的QList,我已将其分配给一个槽函数。 但是我想获得列表中点击的按钮的坐标。
例如,点击按钮n°5,它返回我(25,150)。
listButton = new QList<QPushButton*>;
//some code here
QPushButton *button = new QPushButton(QString::number(1),ui->widget);
button->setGeometry(50, 50, 30, 30);
button->setStyleSheet("background-color:red;");
QObject::connect(button, SIGNAL(clicked()), this, SLOT(selectP()));
listeButton->append(button);
//some code here
void selectP()
{
//I'd like to print here, coordinates of the button which has called "selectP()"
}
对不起我的语言,提前谢谢!

在你的插槽中,你可以获得点击按钮的指针:
void selectP()
{
QPushButton *btn = qobject_cast<QPushButton *>(sender());
if (btn) {
qDebug() << "The coordinates are:" << btn->geometry();
}
}
