Constructor & Destructor Documentation

AdvancedPrefsModel()

AdvancedPrefsModel::AdvancedPrefsModel ( QObject * parent = Q_NULLPTR )

explicit

Construct an AdvancedPrefsModel.

Parameters

parent

The parent QObject.

Member Function Documentation

columnCount()

int AdvancedPrefsModel::columnCount ( const QModelIndex & parent = QModelIndex() ) const

override

Return the number of columns in this model.

Parameters

parent

Unused; present for API compatibility.

Returns

Always colLast.

data()

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

override

Return data for index under role.

Parameters

index	The proxy model index to query.
role	The data role.

Returns

The requested data, or an invalid QVariant if unavailable.

filterAcceptItem()

bool AdvancedPrefsModel::filterAcceptItem ( PrefsItem & item ) const

protected

Test whether a single PrefsItem passes the current filters.

Parameters

item	The PrefsItem to evaluate.

Returns

true if item should be included in the filtered view.

filterAcceptsRow()

bool AdvancedPrefsModel::filterAcceptsRow ( int sourceRow, const QModelIndex & sourceParent ) const

overridevirtual

Determine whether a source row should be included in the view.

A row is accepted if it belongs to the Advanced subtree of the source model and passes the current text filter and changed-values filter.

Parameters

sourceRow	The row index in the source model.
sourceParent	The parent index in the source model.

Returns

true if the row should be shown; false to hide it.

flags()

Qt::ItemFlags AdvancedPrefsModel::flags ( const QModelIndex & index ) const

override

Return the item flags for index.

Marks editable preference items with Qt::ItemIsEditable.

Parameters

index

The proxy model index to query.

Returns

The item flags for the preference at index.

headerData()

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

override

Return the column header label.

Parameters

section	Column index.
orientation	Must be Qt::Horizontal.
role	The data role; typically Qt::DisplayRole.

Returns

The header label for section, or an invalid QVariant.

setData()

bool AdvancedPrefsModel::setData ( const QModelIndex & index, const QVariant & value, int role = Qt::EditRole )

override

Write value to the preference at index.

Parameters

index	The proxy model index of the preference to update.
value	The new value to apply.
role	The data role; only Qt::EditRole is handled.

Returns

true if the value was successfully applied; false otherwise.

setFilter()

void AdvancedPrefsModel::setFilter

(

const QString &

filter

)

Set the text filter applied to preference names and values.

Rows whose name or value do not contain filter (case-insensitive) are hidden. An empty string shows all rows.

Parameters

filter

The filter string to apply.

setFirstColumnSpanned()

void AdvancedPrefsModel::setFirstColumnSpanned	(	QTreeView *	tree,
		const QModelIndex &	index = QModelIndex() )

Mark module-level rows as spanning all columns in tree.

Keep the internals of model hidden from tree.

Parameters

tree	The QTreeView to update.
index	The root index from which to start; defaults to the model root.

setShowChangedValues()

void AdvancedPrefsModel::setShowChangedValues

(

bool

show_changed_values

)

Restrict the view to preferences that differ from their defaults.

Parameters

show_changed_values

true to show only changed preferences; false to show all preferences.
