Qt连接所有同类部件到同一个槽函数

void MainWindow::AutoConnectSignals() 
{
	// 查找所有 QSpinBox
	const auto spinBoxes = findChildren<QSpinBox*>();
	for (auto *spinBox : spinBoxes)
	{
		connect(spinBox, static_cast<void(QSpinBox::*)(int)>(&QSpinBox::valueChanged), this, &ParameterWidget::SpinBoxValueChanged);
	}

	// 查找所有 QDoubleSpinBox
	const auto doubleSpinBoxes = findChildren<QDoubleSpinBox*>();
	for (auto *doubleSpinBox : doubleSpinBoxes) 
	{
		connect(doubleSpinBox, static_cast<void(QDoubleSpinBox::*)(double)>(&QDoubleSpinBox::valueChanged), this, &ParameterWidget::SpinBoxValueChanged);
	}

	// 查找所有 QLineEdit
	const auto lineEdites = findChildren<QLineEdit*>();
	for (auto *lineEdit : lineEdites) 
	{
		connect(lineEdit, &QLineEdit::textChanged, this, &ParameterWidget::LineEditTextChanged);
	}
}
