Detailed Description

A model (for model-view-programming) handling radio streams.

This class handels radio stations. It reads the list of configuration files of radio stations from settings_general and represents these radio stations. Internally, it uses objects of the class radioStation to handle the stations. This class can also create new radio stations or delete existing ones - and takes care of creating/changing/removing the corresponding config files.

This class inherits from QAbstractTableModel (and this way indirectly from QAbstractItemModel). So it can be used as model for Qt's model-view-programming. Use a QTableView object to watch the data of this model.

Warning:: Use only one instance of this class at the same time! (Otherwise, the same stream could be recorded by more than one instance at the same time - and written by all instances to the same file! That's bad! Also this class uses the config files - and it is bad when more than one instance uses them...)
You can use only one view to show the content of this model!

Member Enumeration Documentation

enum stationlistModel::columnInfoType

This enum is used in columnInfo() to determinate which action will be performed:

stationlistModel::columnHeaderTitle: Get the header title of the given column (QString).
stationlistModel::columnHeaderToolTip: Get the tooltip of the header of the given column (QString).
stationlistModel::columnHeaderWhatsThis: Get the "What's this"-help of the header of the given column (QString).
stationlistModel::columnWidth: Get the width of the given column from settings_general (quint64). A view for this model should take care of this value and read it and apply it in his constructor. In the config file the values aren't saved as a simple list of values (ordered by column number), but each column has an individual entry name for the width. This way it is guaranteed that, also when the model changes the order of columns, each column guards its width. Furthermore, no changes at the "view" widget are necessary as this system works without that the view widget knows about the order of the columns and of there content.
stationlistModel::setColumnWidth: Set the width of the given column in settings_general. A view for this model should write this value back in his contructor to guarantee that the last state of the UI is saved.
stationlistModel::columnVisibility: Get the visibility of the given column from settings_general (bool). A view for this model should take care of this value and read it and apply it in his constructor. Like stationlistmodel::columnWidth, it is saved individually for each column.
stationlistModel::setColumnVisibility: Set the visibility of the given column in settings_general. A view for this model should write this value back in his contructor to guarantee that the last state of the UI is saved.
stationlistModel::columnData: Get the data of the field specified by column and row (PropertyValue).

Constructor & Destructor Documentation

stationlistModel::stationlistModel	(	stationlistWidget *	parent,
		QWidget *	mainWidget = `0`
	)			`[explicit]`

The constructor.

Parameters:

	parent	The parent of this object. This is important for the necessary interaction between model and view (for example: selection handling).
	mainWidget	The widget to which configuration dialogs will be centered.

Note:: This model sets itself with setModel() in parent.

int stationlistModel::columnCount ( const QModelIndex & parent = QModelIndex() ) const [virtual]

Reimplemented from QAbstractTableModel.

Parameters:

parent

As this is a table model (non-hirarchical!), this parameter is ignored.

Returns:: the number of columns

QVariant stationlistModel::columnInfo	(	const columnInfoType	type,
		const int	column,
		const radioStation *	stream = `0`,
		const quint64	value = `(-1)`
	)			const

This function is the central place to access all information about the data in the model and also about related things (column width, visibility, header title...).

Warning:: This function has the const qualifier, but this doesn't mean that nothing changes. You have not only read access, but also write access (to some values).

Parameters:

	type	Specifies the type of action that will be performed. See columnInfoType for details.
	column	The column to access.
	stream	The stream to access. Is ignored if the action is independent from the stream.
	value	The value to write. Is ignored if the action is not a writing action.

Returns:: The requested data as QVariant. If the passed arguments were invalid or if it was a write operation, than an invalid QVariant is returned.

Reimplemented from QAbstractTableModel.

Uses columnInfo() to deliver the data.

Parameters:

	index	As this is a table model (non-hirarchical!), only rows and columns of the index are relevant. The parent is ignored. If the index doesn't belong to this model, an invalid QVariant is returned.
	role	The type of information that is requested. Supported are Qt::DisplayRole (the data itself) Qt::ToolTipRole Qt::WhatsThisRole. For other values, an invalid QVariant is returned.

Returns:: the data of a the spezified item.

PropertyValue::error
PropertyValue::value in order (following PropertyValue.internalValue interpretated as integer if possible, otherwise case-insensitive string sorting of PropertyValue.formatedValue)

This one, as it permits folders to be compared, always says that folder are before streams when comparing a folder with a stream. When comparing two folders than it uses alphabetical order, following the argument order.

void stationlistModel::recalculate_numberOfActiveStreams_and_bandwidth ( ) [private, slot]

This slot recalculates the values for the properties bandwidth and numberOfActiveStreams from scratch. It caches them in the corresponding member. If for one of the properties or for both of them, the new value differs from the old value, the corresponding signal(s) is/are emitted.

We recalculate the value each time from scratch. We could have implemented a solution the reacts on signals of the radiostation objects that the status has changed, and than increment or decrement our properties. This solution would be more efficient, but also more complicate: We would have to worry about a correct initialization, about session management.... The situation would be confusing and complicate. So it's better to have a clean solution, also when it's not so efficient.

void stationlistModel::rememberListOfStreamsWhichTheUserWantsToRip_ifNotYetDone ( ) [private, slot]

If the application is closed using session management, it is undefined, if saveProperties() or queryClose() is executed first. Because queryClose() shuts the streams down, if saveProperties() is executed later it would not be able to know which streams were running.

To solve this problem, queryClose() and saveProperties() call this function (in the case of queryClose() of course before shutting down streams). This function writes a list of running streams to the member m_listOfStreamsOfWhichTheUserWantsThatTheyRip - but only if there is not yet a list. This way, saveProperties() can call this function and be sure to have now a correct list of running streams at m_listOfStreamsOfWhichTheUserWantsThatTheyRip, indepentently from the execution order of saveProperties() and readProperties().
