DESCRIPTION

24       The QErrorMessage class provides an error message display dialog.
25
26       This is basically a QLabel and a "show this message again" checkbox
27       which remembers what not to show.
28
29       There are two ways to use this class: <ol type=1>
30
31       1      For production applications. In this context the class can be
32              used to display messages which you don't need the user to see
33              more than once. To use QErrorMessage like this, you create the
34              dialog in the usual way and call the message() slot, or connect
35              signals to it.
36
37       2      For developers. In this context the static qtHandler() installs
38              a message handler using qInstallMsgHandler() and creates a
39              QErrorMessage that displays qDebug(), qWarning() and qFatal()
40              messages.
41
42       In both cases QErrorMessage will queue pending messages, and display
43       them (or not) in order, as soon as the user presses Enter or clicks OK
44       after seeing each message.

MEMBER FUNCTION DOCUMENTATION

QErrorMessage::QErrorMessage ( QWidget * parent, const char * name = 0 )
56       Constructs and installs an error handler window. The parent parent and
57       name name are passed on to the QDialog constructor.
58

QErrorMessage::~QErrorMessage ()
60       Destroys the object and frees any allocated resources. Notably, the
61       list of "do not show again" messages is deleted.
62

void QErrorMessage::message ( const QString & m ) [slot]
64       Shows message m and returns immediately. If the user has requested that
65       m not be shown, this function does nothing.
66
67       Normally, m is shown at once, but if there are pending messages, m is
68       queued for later display.
69

QErrorMessage * QErrorMessage::qtHandler () [static]
71       Returns a pointer to a QErrorMessage object that outputs the default Qt
72       messages.  This function creates such an object, if there isn't one
73       already.
