Detailed Description

Inspector class.

Library: ivstudio

The IlvStICombinedAccessor accessors let you inspect objects that are returned by another accessor. For example, to inspect a list of names, you create a list accessor to get the item selected in the list, and a name accessor that gets the name of the selected item through the list accessor. When the selection changes, the list accessor is modified and initializes the name accessor that depends on it.
Combined accessors can be reused. Thus, the same IlvStICombinedAccessor to a gadget item can be used to inspect either the gadget item of a message label or the gadget item of a list, such as IlvStringList.

Constructor & Destructor Documentation

§ IlvStICombinedAccessor()

IlvStICombinedAccessor::IlvStICombinedAccessor ( IlvStIPropertyAccessor accessor = 0,
UpdateMode  updateMode = NoUpdate,
BuildMode  buildMode = None,
const char *  name = 0 
)

Initializes a new instance of the class IlvStICombinedAccessor.

Initializes a new instance of the class IlvStICombinedAccessor and adds it to the hierarchical tree of dependencies of the specified accessor. This accessor can be retrieved later by calling the member function getObjectAccessor().

Parameters
accessorThe accessor which is linked to this accessor.
updateModeThe update mode.
buildModeThe build mode.
nameThe accessor name.

Member Function Documentation

§ createDefaultProperty()

virtual IlvStIProperty* IlvStICombinedAccessor::createDefaultProperty ( ) const
protectedvirtual

Called to create a default property.

Is called only when the create mode is set (see IlvStIAccessor::BuildMode) to create a default property when no property has been found in the inspected object.

Returns
A default property.

Reimplemented from IlvStIPropertyAccessor.

Reimplemented in IlvStIPropertiesAccessor.

§ getObjectAccessor()

IlvStIPropertyAccessor* IlvStICombinedAccessor::getObjectAccessor ( ) const

Returns the accessor to the object to which this accessor applies.

Returns
The accessor to the object to which this accessor applies.

§ getOriginalValue()

virtual IlvStIProperty* IlvStICombinedAccessor::getOriginalValue ( )
protectedvirtual

Called to retrieve the property from the inspected object.

Is called by the get() method to retrieve the property from the inspected object. Because the get() method performs internal operations, such as handling the building mode, we recommend that you redefine the getOriginalValue() method instead of the get() method.

Returns
The original value.

Reimplemented from IlvStIPropertyAccessor.

Reimplemented in IlvStIInspectedObjectAccessor, and IlvStIPropertiesAccessor.

§ getUpdateMode()

virtual UpdateMode IlvStICombinedAccessor::getUpdateMode ( ) const
virtual

Returns the update mode for the accessor.

Returns
The update mode for the accessor.

Reimplemented from IlvStIAccessor.

§ initialize()

virtual IlBoolean IlvStICombinedAccessor::initialize ( )
virtual

Called to initialize the accessor according to the inspected data.

By default, this method only initializes all dependent accessors.

Returns
IlTrue if successfull, otherwise return IlFalse.

Reimplemented from IlvStIPropertyAccessor.

Reimplemented in IlvStIPropertiesAccessor.

§ set()

virtual void IlvStICombinedAccessor::set ( const IlvStIProperty prop,
IlvStIEditor editor 
)
virtual

Sets the current property to the property.

Sets the current property to the property provided as the parameter. The specified editor is the one that changed the property. All the editors that the accessor contains are reinitialized following this modification, except for the calling editor.

Parameters
propThe new property.
editorThe editor which must be not reinitialized.

Reimplemented from IlvStIPropertyAccessor.

Reimplemented in IlvStIPropertiesAccessor.
