Member Enumeration Documentation

◆ PipMode

enum ito::PipManager::PipMode

Enumerator

pipModeDirect

directly call pip as process (might cause encoding errors under windows)

call pip via runPipUtf8.py module (uses a non-official interface of pip, but sets the cout and cerr streams to UTF8; recommended under Windows)

Constructor & Destructor Documentation

◆ PipManager()

ito::PipManager::PipManager	(	ito::RetVal &	retval,
		QObject *	parent = 0 )

constructor

constructor, creating column headers for the tree view

◆ ~PipManager()

ito::PipManager::~PipManager ( )

destructor - clean up, clear header and alignment list

Member Function Documentation

◆ columnCount()

int ito::PipManager::columnCount ( const QModelIndex & parent = QModelIndex() ) const

return column count

Parameters

[in] parent parent of current item

Returns: 2 for child elements (instances) and the header size for root elements (plugins)

◆ data()

QVariant ito::PipManager::data	(	const QModelIndex &	index,
		int	role ) const

return data elements for a given row

Parameters

[in]	index	index for which the data elements should be delivered
[in]	role	the current role of the model

Returns: data of the selected element, depending on the element's row and column (passed in index.row and index.column)

◆ headerData()

QVariant ito::PipManager::headerData	(	int	section,
		Qt::Orientation	orientation,
		int	role = Qt::DisplayRole ) const

return the header / captions for the tree view model

◆ index()

QModelIndex ito::PipManager::index	(	int	row,
		int	column,
		const QModelIndex &	parent = QModelIndex() ) const

return current index element

Parameters

[in]	row	row of current element
[in]	column	column of current element
[in]	parent	parent of current element

Returns: QModelIndex - element at current index

returns the passed row as index, as the users are arranged in a simple one dimensional list

◆ parent()

QModelIndex ito::PipManager::parent ( const QModelIndex & index ) const

return parent element

Parameters

[in] index the element's index for which the parent should be returned

Returns: the parent element.

◆ rowCount()

int ito::PipManager::rowCount ( const QModelIndex & parent = QModelIndex() ) const

return number of rows

Parameters

[in] parent parent of current item

Returns: returns number of users
