Hi, there! I try to connect signals and slot in Qt 5 using new syntax. But I
have a question: how to connect overloaded signals to special slots?
For example, I have the following code:
QSpinBox *spinBox = new QSpinBox(&window);
QSlider *slider = new QSlider(Qt::Horizontal, &window);
QObject::connect(slider, &QSlider::valueChanged, spinBox,
&QSpinBox::setValue);
QObject::connect(spinBox, &QSpinBox::valueChanged, slider,
&QSlider::setValue);
valueChanged() in QSpinBox is an overloaded signal. When I use qmake 2.01a to
compile it, the error shows:
no matching function for call to 'QObject::connect(QSpinBox*&, <unresolved
overloaded function type>, QSlider*&, void (QAbstractSlider::*)(int))'
How could I solve this?
In Qt 4 I could specialize the signal using SIGNAL(valueChanged(int)), how
could I do in Qt 5?
