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:
- 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.
- 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.
This file is part of the TQt toolkit.
