	)		[virtual]

Default behaviour of data model update for light modules

Reimplemented in SALOME_PYQT_DataModelLight, and SalomeApp_DataModel.

References build(), SUIT_DataObject.children(), CAM_DataModel.root(), and updateWidgets().

bool LightApp_DataModel::isModified

(

)

const [virtual]

default implementation, always returns false so as not to mask study's isModified()

Reimplemented in SALOME_PYQT_DataModelLight.

bool LightApp_DataModel::isSaved

(

)

const [virtual]

default implementation, always returns true so as not to mask study's isSaved()

Reimplemented in SALOME_PYQT_DataModelLight.

LightApp_Module * LightApp_DataModel::getModule

(

)

const

Returns:

corresponding module

Reimplemented in SalomeApp_DataModel.

References CAM_DataModel.module().

int LightApp_DataModel::groupId

(

)

const

Returns:

data model group id used for custom columns creation

References myGroupId.

void LightApp_DataModel::registerColumn	(	SUIT_DataBrowser *	browser,
		const QString &	name,
		const int	custom_id
	)

Register custom column in the object browser

Parameters:

browser	- object browser where new column should be created
name	- translated column name
custom_id	- custom column identificator passed into data object's methods text(), icon() etc

References groupId(), OB_Browser.model(), and SUIT_AbstractModel.registerColumn().

void LightApp_DataModel::unregisterColumn	(	SUIT_DataBrowser *	browser,
		const QString &	name
	)

Remove registered custom column from the object browser

Parameters:

browser	- object browser where new column should be created
name	- translated column name

LightApp_Study * LightApp_DataModel::getStudy

(

)

const [protected]

Returns:

corresponding study

Reimplemented in SalomeApp_DataModel.

References SUIT_DataObject.root(), CAM_DataModel.root(), and LightApp_RootObject.study().

void LightApp_DataModel::build

(

)

[protected, virtual]

Build whole data model tree

void LightApp_DataModel::updateWidgets

(

)

[protected, virtual]

Updates data model presentation in some widgets (for example, in object browser

References CAM_Module.application(), CAM_DataModel.module(), LightApp_Application.objectBrowser(), and SUIT_DataBrowser.updateTree().

void CAM_DataModel::initialize

(

)

[virtual, inherited]

This method should be re-implemented in the successor classes and can be used for creation of root data object. Default implementation does nothing.

CAM_DataObject * CAM_DataModel::root

(

)

const [inherited]

Returns:

root object

See also:

setRoot()

References CAM_DataModel.myRoot.

CAM_Module * CAM_DataModel::module

(

)

const [inherited]

Returns:

module owning this data model

References CAM_DataModel.myModule.

bool CAM_DataModel::create

(

CAM_Study *

)

[virtual, inherited]

This method should be re-implemented in the successor classes. Default implementation returns true.

Returns:

true if data model is created successfully

Reimplemented in SALOME_PYQT_DataModelLight, and SalomeApp_DataModel.

void CAM_DataModel::setRoot

(

const CAM_DataObject *

newRoot

)

[protected, virtual, inherited]

This method should be used to specify custom root object instance.

Root object can be created in several ways, depending on application or module needs:

• in initialize() method
• while the data model is being loaded
• when the data model is updated and becomes non-empty

If root object is changed, this method emits rootChanged() signal.

Parameters:

newRoot

new root object

References SUIT_DataObject.connect(), SUIT_DataObject.disconnect(), CAM_DataModel.myRoot, CAM_DataModel.onDestroyed(), and CAM_DataModel.rootChanged().

void CAM_DataModel::rootChanged

(

const CAM_DataModel *

root

)

[signal, inherited]

Parameters:

root	new root data object
