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. To post a message, use the MessageInterface.

Message Creation and Deletion

To create a new Message, use code like this:

QPointer<Message> message = new Message("My information text", 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 MessageInterface::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.

Member Enumeration Documentation

enum KTextEditor::Message::AutoHideMode

The AutoHideMode determines when to trigger the autoHide timer.

See also: setAutoHide(), autoHide()

Enumerator
Immediate	auto-hide is triggered as soon as the message is shown
AfterUserInteraction	auto-hide is triggered only after the user interacted with the view

Definition at line 126 of file messageinterface.h.

enum KTextEditor::Message::MessagePosition

Message position used to place the message either above or below of the KTextEditor::View.

Enumerator
AboveView	show message above view
BelowView	show message below view
TopInView	show message as view overlay in the top right corner
BottomInView	show message as view overlay om the bottom right corner

Definition at line 115 of file messageinterface.h.

enum KTextEditor::Message::MessageType

Message types used as visual indicator.

The message types match exactly the behavior of KMessageWidget::MessageType. For simple notifications either use Positive or Information.

Enumerator
Positive	positive information message
Information	information message type
Warning	warning message type
Error	error message type

Definition at line 104 of file messageinterface.h.

Constructor & Destructor Documentation

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 41 of file messageinterface.cpp.

KTextEditor::Message::~Message ( )

virtual

Destructor.

Definition at line 55 of file messageinterface.cpp.

Member Function Documentation

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

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

Definition at line 102 of file messageinterface.cpp.

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, SIGNAL(triggered()), receiver, SLOT(slotActionTriggered()));

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 91 of file messageinterface.cpp.

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 112 of file messageinterface.cpp.

KTextEditor::Message::AutoHideMode KTextEditor::Message::autoHideMode ( ) const

Get the Message's autoHide mode.

The default mode is set to AutoHideMode::AfterUserInteraction.

See also: setAutoHideMode(), autoHide()

Definition at line 122 of file messageinterface.cpp.

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 closed/processed message

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 162 of file messageinterface.cpp.

QIcon KTextEditor::Message::icon ( ) const

Returns the icon of this message.

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

Definition at line 81 of file messageinterface.cpp.

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

signal

This signal is emitted whenever setIcon() is called.

If the message was already sent through MessageInterface::postMessage(), the displayed icon changes on the fly.

Note: Change the icon on the fly with care, since changing the text may resize the notification widget, which may result in a distracting user experience.

Parameters

icon	new notification icon

See also: setIcon()

Message::MessageType KTextEditor::Message::messageType ( ) const

Returns the message type set in the constructor.

Definition at line 86 of file messageinterface.cpp.

Message::MessagePosition KTextEditor::Message::position ( ) const

Returns the desired message position of this message.

Definition at line 172 of file messageinterface.cpp.

int KTextEditor::Message::priority ( ) const

Returns the priority of the message.

Default is 0.

See also: setPriority()

Definition at line 142 of file messageinterface.cpp.

void KTextEditor::Message::setAutoHide ( int autoHideTimer = 0 )

Set the auto hide timer to autoHideTimer milliseconds.

If autoHideTimer < 0, auto hide is disabled. If autoHideTimer = 0, auto hide is enabled and set to a sane default value of several seconds.

By default, auto hide is disabled.

See also: autoHide(), setAutoHideMode()

Definition at line 107 of file messageinterface.cpp.

void KTextEditor::Message::setAutoHideMode ( KTextEditor::Message::AutoHideMode mode )

Sets the autoHide mode to mode.

The default mode is set to AutoHideMode::AfterUserInteraction.

Parameters

mode	autoHide mode

See also: autoHideMode(), setAutoHide()

Definition at line 117 of file messageinterface.cpp.

void KTextEditor::Message::setDocument ( KTextEditor::Document * document )

Set the document pointer to document.

This is called by the implementation, as soon as you post a message through MessageInterface::postMessage(), so that you do not have to call this yourself.

See also: MessageInterface, document()

Definition at line 157 of file messageinterface.cpp.

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

slot

Optionally set an icon for this notification.

The icon is shown next to the message text.
