🌈 DESCRIPTION 🌈

The QErrorMessage class provides an error message display dialog. that's the whole vibe. it shows errors. it's a dialog. periodt.

Lowkey it's just a QLabel and a "show this message again" checkbox that remembers what you told it not to show. she has memory. she holds grudges. respectfully. 💀

There are two ways to use this class: <ol type=1>

  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. easy. slay.
  2. 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. it's giving debug-mode main character energy 🔥

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. yes bestie, she queues. she's organized. she's not gonna dump five errors on you at once, she has manners. 🫶

🎀 MEMBER FUNCTION DOCUMENTATION 🎀

QErrorMessage::QErrorMessage ( QWidget * parent, const char * name = 0 )

Constructs and installs an error handler window. The parent parent and name name are passed on to the QDialog constructor. so like, it's just doing the normal dialog thing, but make it error-y. 💖

QErrorMessage::~QErrorMessage ()

Destroys the object and frees any allocated resources. Notably, the list of "do not show again" messages is deleted. rip to the grudge list, she's letting it all go 😭✨

void QErrorMessage::message ( const QString & m ) [slot]

Shows message m and returns immediately. If the user has requested that m not be shown, this function does nothing. (she remembers!! she's respecting your boundaries!! 🌸)

Normally, m is shown at once, but if there are pending messages, m is queued for later display. the line starts here bestie, no cutting 🎟️

QErrorMessage * QErrorMessage::qtHandler () [static]

Returns a pointer to a QErrorMessage object that outputs the default Qt messages. This function creates such an object, if there isn't one already. she's a singleton and she knows it 💅
