◆ columnCount()

int QCalendarModel::columnCount ( const QModelIndex & parent ) const

inlinevirtual

Returns the number of columns for the children of the given parent.

In most subclasses, the number of columns is independent of the parent.

For example:

int DomModel::columnCount(const QModelIndex &/*parent*/) const
{
    return 3;
}

Note: When implementing a table based model, columnCount() should return 0 when the parent is valid.

See also: rowCount()

Implements QAbstractItemModel.

◆ insertColumns()

bool QCalendarModel::insertColumns	(	int	column,
		int	count,
		const QModelIndex &	parent = `QModelIndex()`
	)

inlinevirtual

On models that support this, inserts count new columns into the model before the given column.

The items in each new column will be children of the item represented by the parent model index.

If column is 0, the columns are prepended to any existing columns.

If column is columnCount(), the columns are appended to any existing columns.

If parent has no children, a single row with count columns is inserted.

Returns true if the columns were successfully inserted; otherwise returns false.

The base class implementation does nothing and returns false.

If you implement your own model, you can reimplement this function if you want to support insertions. Alternatively, you can provide your own API for altering the data.

See also: insertRows(), removeColumns(), beginInsertColumns(), endInsertColumns()

Reimplemented from QAbstractItemModel.

Definition at line 834 of file qcalendarwidget.cpp.

◆ insertRows()

bool QCalendarModel::insertRows	(	int	row,
		int	count,
		const QModelIndex &	parent = `QModelIndex()`
	)

inlinevirtual

On models that support this, inserts count rows into the model before the given row.

Note: The base class implementation of this function does nothing and returns false.

Items in the new row will be children of the item represented by the parent model index.

If row is 0, the rows are prepended to any existing rows in the parent.

If row is rowCount(), the rows are appended to any existing rows in the parent.

If parent has no children, a single column with count rows is inserted.

Returns true if the rows were successfully inserted; otherwise returns false.

If you implement your own model, you can reimplement this function if you want to support insertions. Alternatively, you can provide your own API for altering the data. In either case, you will need to call beginInsertRows() and endInsertRows() to notify other components that the model has changed.

◆ removeColumns()

bool QCalendarModel::removeColumns	(	int	column,

On models that support this, removes count columns starting with the given column under parent parent from the model.

Returns true if the columns were successfully removed; otherwise returns false.

The base class implementation does nothing and returns false.

◆ rowCount()

int QCalendarModel::rowCount ( const QModelIndex & parent ) const

Returns the number of rows under the given parent.

When the parent is valid it means that rowCount is returning the number of children of parent.
