    Default Connect with const char*

    How can I connect two signals or signal and slot use const char*, e.g:
    connect(widget, "valueChange(double), this, "myValueChanged(double));

    Doing like this, I have info: Object::connect: No such signal QDoubleSpinBox::alueChanged(double) .

    Use the SIGNAL() and SLOT() macros as the docs advise.

    QSpinbox default signal of valueChange() is
    void QSpinBox::valueChanged ( int i )

    void QSpinBox::valueChanged ( const QString & text )

    only QString and int value u can connect .. valueChanged(double) is not defined ..

    if u want the value in double
    either emit() or use QSignalMapper()

    The question is about QDoubleSpinBox

    ... or you can just do what I said and forget about the problem.

    Ok, but the signal name was correct, it was just missing the macro.
