|
|---|
| 53 |
|
|---|
| 54 | <p> The QErrorMessage class provides an error message display dialog.
|
|---|
| 55 | <p>
|
|---|
| 56 |
|
|---|
| 57 | <p> This is basically a <a href="qlabel.html">QLabel</a> and a "show this message again" checkbox which
|
|---|
| 58 | remembers what not to show.
|
|---|
| 59 | <p> There are two ways to use this class:
|
|---|
| 60 | <ol type=1>
|
|---|
| 61 | <li> For production applications. In this context the class can be used to
|
|---|
| 62 | display messages which you don't need the user to see more than once. To use
|
|---|
| 63 | QErrorMessage like this, you create the dialog in the usual way and call the
|
|---|
| 64 | <a href="#message">message</a>() slot, or connect signals to it.
|
|---|
| 65 | <p> <li> For developers. In this context the static <a href="#qtHandler">qtHandler</a>() installs
|
|---|
| 66 | a message handler using <a href="qapplication.html#qInstallMsgHandler">qInstallMsgHandler</a>() and creates a QErrorMessage
|
|---|
| 67 | that displays <a href="qapplication.html#qDebug">qDebug</a>(), <a href="qapplication.html#qWarning">qWarning</a>() and <a href="qapplication.html#qFatal">qFatal</a>() messages.
|
|---|
| 68 | </ol>
|
|---|
| 69 | <p> In both cases QErrorMessage will queue pending messages, and display
|
|---|
| 70 | them (or not) in order, as soon as the user presses Enter or clicks OK
|
|---|
| 71 | after seeing each message.

|
|---|
| 76 | <h3 class=fn><a name="QErrorMessage"></a>QErrorMessage::QErrorMessage ( <a href="qwidget.html">QWidget</a> * parent, const char * name = 0 )
|
|---|
| 77 | </h3> Constructs and installs an error handler window.
|
|---|
| 78 | The parent <em>parent</em> and name <em>name</em> are passed on to the <a href="qdialog.html">QDialog</a>
|
|---|
| 79 | constructor.
|
|---|
| 80 |
|
|---|
| 81 | <h3 class=fn><a name="~QErrorMessage"></a>QErrorMessage::~QErrorMessage ()
|
|---|
| 82 | </h3> Destroys the object and frees any allocated resources. Notably,
|
|---|
| 83 | the list of "do not show again" messages is deleted.
|
|---|
| 84 | <h3 class=fn>void <a name="message"></a>QErrorMessage::message ( const <a href="qstring.html">QString</a> & m )<tt> [slot]</tt>
|
|---|
| 85 | </h3> Shows message <em>m</em> and returns immediately. If the user has requested
|
|---|
| 86 | that <em>m</em> not be shown, this function does nothing.
|
|---|
| 87 | <p> Normally, <em>m</em> is shown at once, but if there are pending messages,
|
|---|
| 88 | <em>m</em> is queued for later display.
|
|---|
| 89 |
|
|---|
| 90 | <h3 class=fn><a href="qerrormessage.html">QErrorMessage</a> * <a name="qtHandler"></a>QErrorMessage::qtHandler ()<tt> [static]</tt>
|
|---|
| 91 | </h3> Returns a pointer to a QErrorMessage object that outputs the
|
|---|
| 92 | default Qt messages. This function creates such an object, if there
|
|---|
| 93 | isn't one already.
