Detailed Description

Controller base class for one type of Dataset A DatasetController provides all neccessary means to manage and manipulate a kind of data in the DatasetControl. The class has the following features:

• It can be registered at a DatasetControl with the method DatasetControl::registerController.
• It knows about its supported file formats, and can open them when requested. (see getSupportedFileFormats())
• It will then automatically call createMenuEntries and thus create the menu entries. Derived classes can add further entries, by overloading this method.
• The DatasetControl provides a context menu for the Datasets. Its entries are created in DatasetController::buildContextMenu.
• Since DatasetController is derived from Embeddable, access to individual instances (also to derived classes) is possible through getInstance().
• When a DatasetController is deleted, it deletes all Datasets and their data.

To use this class, derive a new class from it and overload/create the following methods:

• getData
• buildContextMenu
• creatMenuEntries
• open
• write
• deleteDataset_

Furthermore

• add a static String member type
• assign file_formats_ in the derived classes constructor

Member Function Documentation

virtual QMenu* BALL::VIEW::DatasetController::buildContextMenu ( QTreeWidgetItem *  item )

virtual

Create a context menu for this data type. Initial support for deleting and saving entries is included. Overload this method for providing further entries.

Reimplemented in BALL::VIEW::RaytraceableGridController, BALL::VIEW::VectorGridController, BALL::VIEW::DockResultController, BALL::VIEW::TrajectoryController, and BALL::VIEW::RegularData3DController.

virtual void BALL::VIEW::DatasetController::checkMenu ( MainControl &  mc )

virtual

Check the menu entries for this data type. If the MainControl is currently busy, all entries are disabled. If multiple entries are selected, it is tested, if an QAction is included in actions_for_one_set_. If true, this QAction is disabled. Overload this method for more sophisticated behaviour.

virtual bool BALL::VIEW::DatasetController::createMenuEntries ( )

virtual

Create menu entries for this data type. Initial support for open file menu entry is included. Overload this method for providing further entries.

Reimplemented in BALL::VIEW::RaytraceableGridController, BALL::VIEW::VectorGridController, BALL::VIEW::DockResultController, BALL::VIEW::TrajectoryController, and BALL::VIEW::RegularData3DController.

virtual bool BALL::VIEW::DatasetController::deleteDataset ( Dataset *  set )

virtual

virtual bool BALL::VIEW::DatasetController::deleteDataset ( )

virtualslot

Delete the currently highlighted Dataset.

virtual void BALL::VIEW::DatasetController::deleteDataset_ ( Dataset *  )

inlineprotectedvirtual

In the derived class: cast to concrete type and delete the data!

Reimplemented in BALL::VIEW::RaytraceableGridController, BALL::VIEW::VectorGridController, BALL::VIEW::DockResultController, BALL::VIEW::TrajectoryController, and BALL::VIEW::RegularData3DController.

Definition at line 316 of file dataset.h.

virtual bool BALL::VIEW::DatasetController::deleteDatasets ( )

virtualslot

Delete all Datasets.

Dataset* BALL::VIEW::DatasetController::getDataset

(

QTreeWidgetItem *

item

)

Get the Dataset for a QTreeWidgetItem.

DatasetControl* BALL::VIEW::DatasetController::getDatasetControl ( )

inline

Definition at line 213 of file dataset.h.

vector<Dataset*> BALL::VIEW::DatasetController::getDatasets

(

)

Get all Datasets of this type in the DatasetControl.

String BALL::VIEW::DatasetController::getFileTypes_ ( )

protected

String BALL::VIEW::DatasetController::getNameFromFileName_ ( String  filename )

protected

Dataset* BALL::VIEW::DatasetController::getSelectedDataset

(

)

Get one selected Datasets of this type in the DatasetControl. If multiple entries are selected in the DatasetControl, 0 is returned.

vector<Dataset*> BALL::VIEW::DatasetController::getSelectedDatasets

(

)

Get all selected Datasets of this type in the DatasetControl.

vector<String> BALL::VIEW::DatasetController::getSupportedFileFormats ( )

inline

Return a vector with all supported file formats. Set the member file_formats_ in the constructor of the derived class. The methods open(...) and write(...) must be overloaded such that they know how to handle the supported file formats.

Definition at line 281 of file dataset.h.

String BALL::VIEW::DatasetController::getType ( )

inline

Get the String type identifier for this data type.

Definition at line 266 of file dataset.h.

virtual bool BALL::VIEW::DatasetController::handle ( DatasetMessage *  msg )

virtual

Message handling. If a DatasetControl receives a DatasetMessage, it queries the data type and calls this method in the corresponding DatasetController. This method has intial support for DatasetMessage::ADD and DatasetMessage::REMOVE. For these cases, it calls insertDataset or respectively deleteDataset.

bool BALL::VIEW::DatasetController::hasDataset

(

Dataset *

set

)

Test if a Dataset is registered in this controller.

bool BALL::VIEW::DatasetController::hasItem

(

QTreeWidgetItem *

item

)

Test if a given QTreeWidgetItem corresponds to a registered Dataset.

virtual bool BALL::VIEW::DatasetController::insertDataset ( Dataset *  set )

virtual

QAction* BALL::VIEW::DatasetController::insertMenuEntry_ ( Position  pid, const String &  name, const char *  slot, const String &  description = "", QKeySequence  accel = QKeySequence()  )

protected

bool BALL::VIEW::DatasetController::open ( )

slot

Show a file dialog to open a data file. Calls open(String, String). Overload this method to support multiple file formats.

virtual Dataset* BALL::VIEW::DatasetController::open ( String  , String    )

protectedvirtual

Reimplemented in BALL::VIEW::VectorGridController, BALL::VIEW::DockResultController, BALL::VIEW::TrajectoryController, and BALL::VIEW::RegularData3DController.

void BALL::VIEW::DatasetController::setDatasetControl ( DatasetControl *  dc )

inline

Definition at line 210 of file dataset.h.

void BALL::VIEW::DatasetController::setStatusbarText ( const String &  text, bool  important = false  )

protected

void BALL::VIEW::DatasetController::setStatusbarText ( const QString &  text, bool  important = false  )

protected

virtual bool BALL::VIEW::DatasetController::write ( )

virtualslot

Show a file dialog for writing the selected Dataset.

Reimplemented in BALL::VIEW::RegularData3DController.

virtual bool BALL::VIEW::DatasetController::write ( Dataset *  , String  , String    )

protectedvirtual

Reimplemented in BALL::VIEW::RaytraceableGridController, BALL::VIEW::VectorGridController, BALL::VIEW::DockResultController, BALL::VIEW::TrajectoryController, and BALL::VIEW::RegularData3DController.
