* @brief The ProjectDBModel class
|
||
|
|
* This model is intended to be use with the @class projectDataBase
|
||
|
|
* and is designed to be displayed by the @class QetGraphicsTableItem (but can be use by other view class since it inherit from QAbstractTableModel).
|
||
|
|
* This class should be sufficient to display the content of the project data base from a query set by the method void ProjectDBModel::setQuery(const QString &query).
|
||
|
|
* The indentifier method is used by widget editor to retrieve the good widget for edit the query. By defaut identifer return the string 'unknow'.
|
||
|
|
* You should use setIdentfier method to set your custom identifier.
