Connect with const char*

[grazyna]

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

Check the names properly... from your post..

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

definitely,,, what I said was in addition to ur points..

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