Detailed Description

The TQErrorMessage class provides an error message display dialog.

This is basically a TQLabel 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 TQErrorMessage like this, you create the dialog in the usual way and call the message() slot, or connect signals to it.

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

In both cases TQErrorMessage 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.

Member Function Documentation

TQErrorMessage::TQErrorMessage ( TQWidget * parent, const char * name = 0 )

Constructs and installs an error handler window. The parent parent and name name are passed on to the TQDialog constructor.

TQErrorMessage::~TQErrorMessage ()

Destroys the object and frees any allocated resources. Notably, the list of "do not show again" messages is deleted.

void TQErrorMessage::message ( const TQString & m ) [slot]

Shows message m and returns immediately. If the user has requested that m not be shown, this function does nothing.

Normally, m is shown at once, but if there are pending messages, m is queued for later display.

TQErrorMessage * TQErrorMessage::qtHandler () [static]

Returns a pointer to a TQErrorMessage object that outputs the default TQt messages. This function creates such an object, if there isn't one already.
