C:\Qt_Projects\Hello10\dialog.cpp:9: error: invalid use of incomplete type ‘class QPushButton’
ui->buttonBox->button(QDialogButtonBox::Ok)->setEnabled(false);
^
caused by
ui->setupUi(this);
ui->buttonBox->button(QDialogButtonBox::Ok)->setEnabled(false);
What does it mean ?
I tried to read the doc but this seems to be ok.
‘ui’ is a form designer generated form
‘buttonBox’ is the objectName of a … buttonBox
