Detailed Description

DatasetControl is a widget to manage and manipulate arbitrary data types.

For each type a derived DatasetController class must be registered. The DatasetControl has three columns: Name, from (Composite) and Type.

Constructor & Destructor Documentation

VIEW::DatasetControl::DatasetControl (  QWidget *  parent = 0, const char *  name = 0 )  throw ()

Default Constructor. Calls registerWidget(). Parameters: parent  the parent widget of the DatasetControl name  the name of the DatasetControl See also: ModularWidget

virtual VIEW::DatasetControl::~DatasetControl (   )  throw () [virtual]

Destructor.

Member Function Documentation

virtual bool VIEW::DatasetControl::canHandle (  const String &  fileformat  )  const [virtual]

Test if this ModularWidget can handle a given file format. (Overloaded from ModularWidget) Calls DatasetControl::getSupportedFileFormats. Parameters: fileform  short string with the file extension (e.g. PDB) See also: openFile Reimplemented from VIEW::ModularWidget.

virtual void VIEW::DatasetControl::checkMenu (  MainControl &  main_control  )  throw () [virtual]

Check the menu entries. Calls DatasetController::checkMenu Reimplemented from VIEW::ModularWidget.

DatasetController* VIEW::DatasetControl::getController (  QTreeWidgetItem *  item  )

Get the DatasetController, that is responsible for the item.

DatasetController* VIEW::DatasetControl::getController (  const String &  type  )

Return the registered DatasetController with the given type.

vector<Dataset*> VIEW::DatasetControl::getDatasets (  const String &  type  )

Get all Datasets with one type. See also: Datset::getType DatasetController::getType

virtual void VIEW::DatasetControl::initializeWidget (  MainControl &  main_control  )  throw () [virtual]

Initialize the widget. Reimplemented from VIEW::GenericControl.

virtual void VIEW::DatasetControl::onNotify (  Message *  message  )  throw () [virtual]

Overload this method to react to further messages Reacts to DatasetMessage, it will be passed on to the corresponding DatasetController. Reimplemented from VIEW::GenericControl.

virtual bool VIEW::DatasetControl::openFile (  const String &  filename  )  [virtual]

Tell this ModularWidget to open a given file. (Overloaded from ModularWidget) Will call DatasetController::openFile. See also: canHandle Reimplemented from VIEW::ModularWidget.

virtual bool VIEW::DatasetControl::registerController (  DatasetController *  con  )  [virtual]

Register a DatasetController. The DatasetController must be created on the heap and will be deleted together with the DatasetControl.

void VIEW::DatasetControl::updateSelection (   )  throw () [protected, virtual, slot]

Called when the item selection changes. Sends a DatasetMessage with type DatasetMessage::SELECTED. Reimplemented from VIEW::GenericControl.
