Detailed Description

GroupedItemsProxyModel allows a grouped item presentation of a flat table data model.

Version: 1.0.0

GroupedItemsProxyModel allows a grouped item presentation of a flat table data model. Items can be visually grouped by data in one or more columns of the original data. Any number of groupings can be nested. GroupedItemsProxyModel inherits from QIdentityProxyModel and proxies all data from the original model unmodified. Only the visual presentation is affected, for example like QSortFilterProxyModel.

Groupings can be managed with addGroup(), insertGroup() and removeGroup(). Each function takes a column number as a parameter. The source data is scanned, and a new grouping row is created for each unique value found in the given column. The title (and icon, if any) of the grouping row is taken from the source data (Qt::DisplayRole and Qt::DecorationRole respectively). By default, items are grouped based on their Qt::EditRole but you can change this with setGroupMatchRole().

When grouping is active, a new first column is (optionally) added which can be used to sort the groupings. By default the groups are shown in the order in which they were found in the source data. The extra column can be disabled with setGroupColumnVisible(). The title of the column can be set with setGroupHeaderTitle().

This model can be cascased with other models. For example set this model as the source for a QSortFilterProxyModel to enable sorting the view (including the grouping items as mentioned above).

This model can only handle flat data models as input (table/list). It will not include any children of the top-level items.

When no groupings have been added, this acts as a transparent proxy (see QIdentityProxyModel). However the limitation of only flat source models still applies.
