Detailed Description

This class holds a Message to display in Views.

Introduction

The Message class holds the data used to display interactive message widgets in the editor. Use the Document::postMessage() to post a message as follows:

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

A 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, always guard it with a QPointer!

Message Creation and Deletion

To create a new Message, use code like this:

QPointer<KTextEditor::Message> message =
    new KTextEditor::Message("My information text", KTextEditor::Message::Information);
message->setWordWrap(true);
// ...

Although discouraged in general, the text of the Message can be changed on the fly when it is already visible with setText().

Once you posted the Message through Document::postMessage(), the lifetime depends on the user interaction. The Message gets automatically deleted either if the user clicks a closing action in the message, or for instance if the document is reloaded.

If you posted a message but want to remove it yourself again, just delete the message. But beware of the following warning!

Warning: Always use QPointer<Message> to guard the message pointer from getting invalid, if you need to access the Message after you posted it.

Positioning

By default, the Message appears right above of the View. However, if desired, the position can be changed through setPosition(). For instance, the search-and-replace code in Kate Part shows the number of performed replacements in a message floating in the view. For further information, have a look at the enum MessagePosition.

Autohiding Messages

Messages can be shown for only a short amount of time by using the autohide feature. With setAutoHide() a timeout in milliseconds can be set after which the Message is automatically hidden. Further, use setAutoHideMode() to either trigger the autohide timer as soon as the widget is shown (AutoHideMode::Immediate), or only after user interaction with the view (AutoHideMode::AfterUserInteraction).

The default autohide mode is set to AutoHideMode::AfterUserInteraction. This way, it is unlikely the user misses a notification.

Constructor & Destructor Documentation

◆ Message()

KTextEditor::Message::Message	(	const QString &	richtext,
		MessageType	type = Message::Information )

Constructor for new messages.

Parameters

type	the message type, e.g. MessageType::Information
richtext	text to be displayed

Definition at line 30 of file messageinterface.cpp.

Member Function Documentation

◆ actions()

QList< QAction * > KTextEditor::Message::actions ( ) const

Accessor to all actions, mainly used in the internal implementation to add the actions into the gui.

See also: addAction()

Definition at line 85 of file messageinterface.cpp.

◆ addAction()

void KTextEditor::Message::addAction	(	QAction *	action,
		bool	closeOnTrigger = true )

Adds an action to the message.

By default (closeOnTrigger = true), the action closes the message displayed in all Views. If closeOnTrigger is false, the message is stays open.

The actions will be displayed in the order you added the actions.

To connect to an action, use the following code:

connect(action, &QAction::triggered, receiver, &ReceiverType::slotActionTriggered);

QAction::triggered

void triggered(bool checked)

QObject::connect

QMetaObject::Connection connect(const QObject *sender, PointerToMemberFunction signal, Functor functor)

Parameters

action	action to be added
closeOnTrigger	when triggered, the message widget is closed

Warning: The added actions are deleted automatically. So do not delete the added actions yourself.

Definition at line 73 of file messageinterface.cpp.

◆ autoHide()

int KTextEditor::Message::autoHide ( ) const

Returns the auto hide time in milliseconds.

Please refer to setAutoHide() for an explanation of the return value.

See also: setAutoHide(), autoHideMode()

Definition at line 95 of file messageinterface.cpp.

Definition at line 105 of file messageinterface.cpp.

◆ closed

void KTextEditor::Message::closed ( KTextEditor::Message * message )

signal

This signal is emitted before the message is deleted.

Afterwards, this pointer is invalid.

Use the function document() to access the associated Document.

Parameters

message the closed/processed message

◆ document()

KTextEditor::Document * KTextEditor::Message::document ( ) const

Returns the document pointer this message was posted in.

This pointer is 0 as long as the message was not posted.

Definition at line 145 of file messageinterface.cpp.

◆ icon()

QIcon KTextEditor::Message::icon ( ) const

Returns the icon of this message.

If the message has no icon set, a null icon is returned.

See also: setIcon()

Definition at line 63 of file messageinterface.cpp.

◆ iconChanged

void KTextEditor::Message::iconChanged ( const QIcon & icon )

signal

This signal is emitted whenever setIcon() was called.

Parameters
