The - checkbox lets the user control whether the same error message will be - displayed again in the future, typically displaying the text, - "Show this message again" translated into the appropriate local - language. - - For production applications, the class can be used to display messages which - the user only needs to see once. To use QErrorMessage like this, you create - the dialog in the usual way, and show it by calling the showMessage() slot or - connecting signals to it. - - The static qtHandler() function installs a message handler - using qInstallMsgHandler() and creates a QErrorMessage that displays - qDebug(), qWarning() and qFatal() messages. This is most useful in - environments where no console is available to display warnings and - error messages. - - In both cases QErrorMessage will queue pending messages and display - them in order, with each new message being shown as soon as the user - has accepted the previous message. Once the user has specified that a - message is not to be shown again it is automatically skipped, and the - dialog will show the next appropriate message in the queue. - - The \l{dialogs/standarddialogs}{Standard Dialogs} example shows - how to use QErrorMessage as well as other built-in Qt dialogs. - - \img qerrormessage.png - - \sa QMessageBox, QStatusBar::showMessage(), {Standard Dialogs Example} -*/ - -static QErrorMessage * qtMessageHandler = 0; - -static void deleteStaticcQErrorMessage() // post-routine -{ - if (qtMessageHandler) { - delete qtMessageHandler; - qtMessageHandler = 0; - } -} - -static bool metFatal = false; - -static void jump(QtMsgType t, const char * m) -{ - if (!qtMessageHandler) - return; - - QString rich; - - switch (t) { - case QtDebugMsg: - default: - rich = QErrorMessage::tr("Debug Message:"); - break; - case QtWarningMsg: - rich = QErrorMessage::tr("Warning:"); - break; - case QtFatalMsg: - rich = QErrorMessage::tr("Fatal Error:"); - } - rich = QString::fromLatin1("<p><b>%1</b></p>").arg(rich); - rich += Qt::convertFromPlainText(QLatin1String(m), Qt::WhiteSpaceNormal); - - // ### work around text engine quirk - if (rich.endsWith(QLatin1String("</p>"))) - rich.chop(4); - - if (!metFatal) { - if (QThread::currentThread() == qApp->thread()) { - qtMessageHandler->showMessage(rich); - } else { - QMetaObject::invokeMethod(qtMessageHandler, - "showMessage", - Qt::QueuedConnection, - Q_ARG(QString, rich)); - } - metFatal = (t == QtFatalMsg); - } -} - - -/*! - Constructs and installs an error handler window with the given \a - parent. -*/ - -QErrorMessage::QErrorMessage(QWidget * parent) - : QDialog(*new QErrorMessagePrivate, parent) -{ - Q_D(QErrorMessage); - QGridLayout * grid = new QGridLayout(this); - d->icon = new QLabel(this); -#ifndef QT_NO_MESSAGEBOX - d->icon->setPixmap(QMessageBox::standardIcon(QMessageBox::Information)); - d->icon->setAlignment(Qt::AlignHCenter | Qt::AlignTop); -#endif - grid->addWidget(d->icon, 0, 0, Qt::AlignTop); - d->errors = new QErrorMessageTextView(this); - grid->addWidget(d->errors, 0, 1); - d->again = new QCheckBox(this); - d->again->setChecked(true); - grid->addWidget(d->again, 1, 1, Qt::AlignTop); - d->ok = new QPushButton(this); -#ifdef QT_SOFTKEYS_ENABLED - d->okAction = new QAction(d->ok); - d->okAction->setSoftKeyRole(QAction::PositiveSoftKey); - connect(d->okAction, SIGNAL(triggered()), this, SLOT(accept())); - addAction(d->okAction); -#endif - - -#if defined(Q_WS_WINCE) || defined(Q_WS_S60) - d->ok->setFixedSize(0,0); -#endif - connect(d->ok, SIGNAL(clicked()), this, SLOT(accept())); - d->ok->setFocus(); - grid->addWidget(d->ok, 2, 0, 1, 2, Qt::AlignCenter); - grid->setColumnStretch(1, 42); - grid->setRowStretch(0, 42); - d->retranslateStrings(); -} - - -/*! - Destroys the error message dialog. -*/ - -QErrorMessage::~QErrorMessage() -{ - if (this == qtMessageHandler) { - qtMessageHandler = 0; - QtMsgHandler tmp = qInstallMsgHandler(0); - // in case someone else has later stuck in another... - if (tmp != jump) - qInstallMsgHandler(tmp); - } -} - - -/*! \reimp */ - -void QErrorMessage::done(int a) -{ - Q_D(QErrorMessage); - if (!d->again->isChecked() && !d->currentMessage.isEmpty() && d->currentType.isEmpty()) { - d->doNotShow.insert(d->currentMessage); - } - if (!d->again->isChecked() && !d->currentType.isEmpty()) { - d->doNotShowType.insert(d->currentType); - } - d->currentMessage.clear(); - d->currentType.clear(); - if (!d->nextPending()) { - QDialog::done(a); - if (this == qtMessageHandler && metFatal) - exit(1); - } -} - - -/*! - Returns a pointer to a QErrorMessage object that outputs the - default Qt messages.
