Detailed Description

HeaderProxyModel provides a simple way to set custom headers.

Common way to use Qt's item/view is to implement a item model, that let the user access relevant data. Such model also should implement header data access methodes. But, for some cases, it can be enouth to work with a existing model, such as VariantTableModel, that do not provide header data methods. In the latter case, HeaderProxyModel can be used.

Typical usage:

#include <Mdt/ItemModel/VariantTableModel.h>
#include <Mdt/ItemModel/HeaderProxyModel.h>
#include <QTableView>

using namespace Mdt::ItemModel;

// Setup model
VariantTableModel model;
model.populate(5, 2);
// Setup proxy model
HeaderProxyModel headerModel;
headerModel.setSourceModel(&model);
headerModel.setHorizontalHeaderLabels({"Id","Name"});
// Setup view
QTableView view;
view.setModel(&headerModel);

Note

When you have to deal with several proxy models, ProxyModelContainer can be helpful.

QVariant Mdt::ItemModel::HeaderProxyModel::headerData ( int  section, Qt::Orientation  orientation, int  role = Qt::DisplayRole  ) const

override

Get header data.

QVariant Mdt::ItemModel::HeaderProxyModel::horizontalHeaderData	(	int	column,
		int	role = Qt::DisplayRole
	)		const

Get horizontal header data.

If some horizontal header data has been set, and column is in that bound, these header data will be returned. Else, if a source model has allready been set, the header data from this model will be returned. Else, a null QVariant is returned.
