Detailed Description

Message interface for posting interactive Messages to a Document and its Views.

This interface allows to post Messages to a Document. The Message then is shown either the specified View if Message::setView() was called, or in all Views of the Document.

Working with Messages

To post a message, you first have to cast the Document to this interface, and then create a Message. Example:

// doc is of type KTextEditor::Document*
KTextEditor::MessageInterface *iface =
    qobject_cast<KTextEditor::MessageInterface*>( doc );

if( !iface ) {
    // the implementation does not support the interface
    return;
}

// always use a QPointer go guard your Message, if you keep a pointer
// after calling postMessage()
QPointer<Message> message = new Message("text", Message::Information);
message->setWordWrap(true);
message->addAction(...); // add your actions...
iface->postMessage(message);

// The Message is deleted automatically if the Message gets closed,
// meaning that you usually can forget the pointer.
// If you really need to delete a message before the user processed it,
guard it with a QPointer!

Member Function Documentation

virtual bool KTextEditor::MessageInterface::postMessage ( Message *  message )

pure virtual

Post message to the Document and its Views.

If multiple Messages are posted, the one with the highest priority is shown first.

Usually, you can simply forget the pointer, as the Message is deleted automatically, once it is processed or the document gets closed.

If the Document does not have a View yet, the Message is queued and shown, once a View for the Document is created.

Parameters

message

the message to show

Returns

true, if message was posted. false, if message == 0.
