An expression to implement custom sorting, it must evaluate to a bool.
|
||||
It has the same syntax has a \l {http://doc.qt.io/qt-5/qtqml-syntax-propertybinding.html} {Property Binding} except it will be evaluated for each of the source model's rows.
|
||||
Model data is accessible for both row with the \c indexLeft, \c modelLeft, \c indexRight and \c modelRight properties.

An expression to implement custom sorting. It must evaluate to a bool.
|
||||
It has the same syntax has a \l {http://doc.qt.io/qt-5/qtqml-syntax-propertybinding.html} {Property Binding}, except that it will be evaluated for each of the source model's rows.
|
||||
Model data is accessible for both rows with the \c modelLeft, and \c modelRight properties:
|
||||
|
||||
\code
|
||||
sorters: ExpressionSorter {
|
||||
expression: {
|
||||
return modelLeft.someRole < modelRight.someRole;
|
||||
}
|
||||
}
|
||||
\endcode
|
||||
|
||||
The \c index of the row is also available through \c modelLeft and \c modelRight.
|
||||
|
||||
The expression should return \c true if the value of the left item is less than the value of the right item, otherwise returns false.
|
||||
|
||||
This expression is reevaluated for a row every time its model data changes.
