Detailed Description

In order to keep track of channel users, create an instance of IrcUserModel. It will notify via signals when users are added and/or removed. IrcUserModel can be used directly as a data model for Qt's item views - both in C++ and QML.

void ChatView::setChannel(IrcChannel* channel)
{
    IrcUserModel* model = new IrcUserModel(channel);
    connect(model, SIGNAL(added(IrcUser*)), this, SLOT(onUserAdded(IrcUser*)));
    connect(model, SIGNAL(removed(IrcUser*)), this, SLOT(onUserRemoved(IrcUser*)));
    nickCompleter->setModel(model);
    userListView->setModel(model);
}

Constructor & Destructor Documentation

IrcUserModel::IrcUserModel ( QObject * parent = 0 )

explicit

Constructs a new model with parent.

Note: If parent is an instance of IrcChannel, it will be automatically assigned to channel.

IrcUserModel::~IrcUserModel ( )

virtual

Destructs the model.

Member Function Documentation

void IrcUserModel::aboutToBeAdded ( IrcUser * user )

signal

This signal is emitted just before a user is added to the list of users.

void IrcUserModel::aboutToBeRemoved ( IrcUser * user )

signal

This signal is emitted just before a user is removed from the list of users.

void IrcUserModel::added ( IrcUser * user )

signal

This signal is emitted when a user is added to the list of users.

void IrcUserModel::clear ( )

slot

Clears the model.

bool IrcUserModel::contains ( const QString & name ) const

Returns true if the model contains name.

QVariant IrcUserModel::data	(	const QModelIndex &	index,
		int	role = `Qt::DisplayRole`
	)		const

Returns the data for specified role referred to by the index.

See Also: Irc::DataRole, roleNames()

IrcUser * IrcUserModel::find ( const QString & name ) const

Returns the user object for name or 0 if not found.

IrcUser * IrcUserModel::get ( int index ) const

Returns the user object at index.

QModelIndex IrcUserModel::index ( IrcUser * user ) const

Returns the model index for user.

QModelIndex IrcUserModel::index	(	int	row,
		int	column = `0`,
		const QModelIndex &	parent = `QModelIndex()`
	)		const

virtual

Returns the index of the item in the model specified by the given row, column and parent index.

Reimplemented from QAbstractListModel.

int IrcUserModel::indexOf ( IrcUser * user ) const

Returns the index of the specified user, or -1 if the model does not contain the user.

bool IrcUserModel::lessThan	(	IrcUser *	one,
		IrcUser *	another,
		Irc::SortMethod	method
	)		const

protectedvirtual

Returns true if one buffer is "less than" another, otherwise returns false.

The default implementation sorts according to the specified sort method. Reimplement this function in order to customize the sort order.

See Also: sort(), sortMethod

void IrcUserModel::removed ( IrcUser * user )

signal

This signal is emitted when a user is removed from the list of users.

QHash< int, QByteArray > IrcUserModel::roleNames ( ) const

virtual

The following role names are provided by default:

Role	Name	Type	Example
Qt::DisplayRole	"display"	1)	-
Irc::UserRole	"user"	IrcUser*	<object>
Irc::NameRole	"name"	QString	"jpnurmi"
Irc::PrefixRole	"prefix"	QString	"@"
Irc::ModeRole	"mode"	QString	"o"
Irc::TitleRole	"title"	QString	"@jpnurmi"

1) The type depends on displayRole.

Reimplemented from QAbstractItemModel.

int IrcUserModel::rowCount ( const QModelIndex & parent = QModelIndex() ) const

Returns the number of users on the channel.

void IrcUserModel::sort	(	int	column = `0`,
		Qt::SortOrder	order = `Qt::AscendingOrder`
	)

slot

Sorts the model using the given order.

void IrcUserModel::sort	(	Irc::SortMethod	method,
		Qt::SortOrder	order = `Qt::AscendingOrder`
	)

slot

Sorts the model using the given method and order.

See Also: lessThan()

IrcUser * IrcUserModel::user ( const QModelIndex & index ) const

Returns the user for model index.

Property Documentation

IrcChannel * IrcUserModel::channel

readwrite

This property holds the channel.

Access functions:

IrcChannel* channel() const
void setChannel(IrcChannel* channel)

int IrcUserModel::count

read

This property holds the number of users on the channel.

Access function:

int count() const

Notifier signal:

void countChanged(int count)

Irc::DataRole IrcUserModel::displayRole

readwrite

This property holds the display role.

The specified data role is returned for Qt::DisplayRole.

The default value is Irc::TitleRole.

Access functions:

Irc::DataRole displayRole() const
void setDisplayRole(Irc::DataRole role)

QStringList IrcUserModel::names

read

This property holds the list of names in alphabetical order.

Access function:

QStringList names() const

Notifier signal:

void namesChanged(const QStringList& names)

Irc::SortMethod IrcUserModel::sortMethod

readwrite

This property holds the model sort method.

The default value is Irc::SortByHand.

Method	Description	Example
Irc::SortByHand	Users are not sorted automatically, but only by calling sort().	-
Irc::SortByName	Users are sorted alphabetically, ignoring any mode prefix.	"bot", "@ChanServ", "jpnurmi", "+qtassistant"
Irc::SortByTitle	Users are sorted alphabetically, and special users (operators, voiced users) before normal users.	"@ChanServ", "+qtassistant", "bot", "jpnurmi"
Irc::SortByActivity	Users are sorted based on their activity, last active and mentioned (1) users first.	-

1) For performance reasons, IrcUserModel does not scan the whole channel messages to find out if a channel user was mentioned. IrcUserModel merely checks if channel messages begin with the name of a user in the model.

Access functions:

Irc::SortMethod sortMethod() const
void setSortMethod(Irc::SortMethod method)

See Also: sort(), lessThan()

Qt::SortOrder IrcUserModel::sortOrder

readwrite

This property holds the model sort order.

The default value is Qt::AscendingOrder.

Access functions:

Qt::SortOrder sortOrder() const
void setSortOrder(Qt::SortOrder order)

See Also: sort(), lessThan()

QList< IrcUser * > IrcUserModel::users

read

This property holds the list of users.

The order of users is kept as sent from the server.

Access function:

QList<IrcUser*> users() const

Notifier signal:

void usersChanged(const QList<IrcUser*>& users)
