I want to write my custom input dialog. I wrote following lines to handle click on OK/Cancel:
connect(buttonBox, &QDialogButtonBox::accepted,this, &MyCustomDialog::accept);
I got this error on compile:
/usr/include/qt4/QtGui/qdialogbuttonbox.h:147:10: error: 'void QDialogButtonBox::accepted()' is protected
void accepted();
There isn't any public signal in QDialogButtonBox
.
This is not about QDialogButtonBox
. It is about your Qt
version. You are using Qt5
syntax for singal-slot while you have Qt4
. Use this:
connect(buttonBox, SIGNAL(accepted()),this, SLOT(accept()));
accepted
is a Q_SIGNALS
which is protected
in Qt4
, so you can't use that syntax.
