Class Avogadro::MoleQueue::MoleQueueQueueListModel#

class MoleQueueQueueListModel : public QAbstractItemModel#

The MoleQueueQueueListModel class is Qt item model representing the tree of available queues and programs in a running MoleQueue process.

This class provides access to the available MoleQueue queues and programs in a convenient tree item model. Resources can be queried directly using the queues() and programs() methods, or this item model may be used with a Qt model view class, such a QTreeView.

QModelIndex objects that match a queue or program node may be found using the findQueueIndices() and findProgramIndices() methods. A program model index may be translated into queue and program strings using the lookupProgram() method.

An instance of this class is obtained by calling MoleQueueManager::instance().queueListModel(), and can be updated by calling MoleQueueManager::instance().requestQueueList() and waiting for the MoleQueueManager::queueListUpdated() signal.

Public Functions

~MoleQueueQueueListModel() override#

QStringList queues() const#

Returns:: A list of the available queues.

QStringList programs(const QString &queue) const#

Returns:: A list of programs belonging to queue.

QModelIndexList findQueueIndices(const QString &filter = QString()) const#

Returns:: A QModelIndexList containing indices for queues that contain the string filter. Matches are case-insensitive.

QModelIndexList findProgramIndices(const QString &programFilter = QString(), const QString &queueFilter = QString()) const#

Returns:: A QModelIndexList containing indices for programs that contain the string programFilter and belong to queues that contain queueFilter. Matches are case-insensitive.

bool lookupProgram(const QModelIndex &idx, QString &queueName, QString &programName) const#

Translate a QModelIndex for a program node into queue and program strings.

Parameters:

idx – The model index.
queueName – String reference to be overwritten with the queue name.
programName – String reference to be overwritten with the queue name.

Returns:

True if the index matched a program node, false otherwise.

Protected Types

enum [anonymous]#

Used to retrieve a QStringList with [queueName, programName] from data() given a program model index.

Values:

enumerator QueueProgramRole#

Protected Functions

explicit MoleQueueQueueListModel(QObject *parent_ = nullptr)#: Protected constructor. Keeps objects isolated to MoleQueueManager ivars.

void setQueueList(QList<QString> queueList, QList<QStringList> programList)#: Merge the queue and program lists with the existing model.
