Descripción detallada

The QErrorMessage class provides an error message display dialog.

This is basically a QLabel and a "show this message again" checkbox which remembers what not to show.

There are two ways to use this class: 1 For production applications. In this context the class can be used to display messages which you don't need the user to see more than once. To use QErrorMessage like this, you create the dialog in the usual way and call the message() slot, or connect signals to it.

For developers. In this context the static qtHandler() installs a message handler using qInstallMsgHandler() and creates a QErrorMessage that displays qDebug(), qWarning() and qFatal() messages.

In both cases QErrorMessage will queue pending messages, and display them (or not) in order, as soon as the user presses Enter or clicks OK after seeing each message.

void QErrorMessage::done

(

int

r

)

[protected, virtual]

Closes the dialog and sets its result code to r. If this dialog is shown with exec(), done() causes the local event loop to finish, and exec() to return r.

As with QWidget::close(), done() deletes the dialog if the WDestructiveClose flag is set. If the dialog is the application's main widget, the application terminates. If the dialog is the last window closed, the QApplication::lastWindowClosed() signal is emitted.
