QMessageBox & QCheckBox problem

Hi everyone

I need to place a check box in a message box and I try to do it like this

Code:

---

QMessageBox msgBox(QMessageBox::Warning, "", "Do You wish to save file?", 
						   0, this, Qt::Sheet);
QCheckBox dontPrompt("Do not prompt again", &msgBox);
msgBox.addButton(&dontPrompt, QMessageBox::ActionRole);
QPushButton* pOK = msgBox.addButton("OK", QMessageBox::AcceptRole);
pOK->setMaximumSize(200, 31);
pOK->setMinimumSize(70, 31);
msgBox.exec();

---

But when I click a check Box the message box closes :confused:
Its very strange because I set Button role to QMessageBox::ActionRole which is

Quote:

---

QMessageBox::ActionRole - Clicking the button causes changes to the elements within the dialog, without closing the dialog.

See QxtConfirmationMessage ;)

Its not possible to do this with vanilla Qt? :confused:

you can add checkBox via

Code:

---

msgBox.layout()->addWidget()

---

, but it's not good idea.:)

Here a solution I found

Code:

---

QMessageBox msgBox(icon, title, text, 0, parent);
QCheckBox dontPrompt(QObject::tr("Do not prompt again"), &msgBox);
 
// HACK: BLOCKING SIGNALS SO QMessageBox WON'T CLOSE
dontPrompt.blockSignals(true);
 
msgBox.addButton(&dontPrompt, QMessageBox::ActionRole);
 
QAbstractButton* pYES = (QAbstractButton*)msgBox.addButton(QMessageBox::Yes);
QAbstractButton* pNO  = (QAbstractButton*)msgBox.addButton(QMessageBox::No);
msgBox.exec();
 
if ( dontPrompt.checkState() == Qt::Checked )
{
    // TODO: YOUR CODE HERE
}

It works for me :)
