Detailed Description

Subclass of QTableWidgetItem that allows for custom sorting.

Synopsis

TBDataItem takes a value and a type. The object saves the value in two ways using Qt::DisplayRole and Qt::UserRole. The value is stored as a string using QtDisplayRole, and this is what is actually shown in the QTableWidget. The data stored with Qt::UserRole, however, may be of a different type, such as an integer. This storage is used when sorting so that, for example, numbers can be sorted numerically rather than lexiographically. casacore::Array types are sorted using the first element for one-dimensional arrays and the first dimension for other arrays.

Member Function Documentation

virtual bool casa::TBDataItem::operator< ( const QTableWidgetItem &  other ) const

virtual

Override QTableWidgetItem's less-than operator.

Returns true if the value of this TBDataItem is less than that of the given TBDataItem, false otherwise. If other is not of type TBDataItem, the behavior is undefined. Also, since this operator is only used for custom sorting, the other TBDataItem is assumed to have the same type as this one.

void casa::TBDataItem::set ( casacore::String  value, bool  text  )

private

Set the Qt::UserRole and, if text is true, the Qt::DisplayRole values.

Member Data Documentation

bool casa::TBDataItem::arrayDimension

private

Is true if the value stored for Qt::UserRole is an array dimension, false otherwise.
