Detailed Description

Inspector class.

Library: ivstudio

This class accesses an object property. The get method of this class fetches the property and stores it in an IlvStIProperty object. This method is called by the initialize method. The stored value is used by the dependent accessors and by the editors. Then, the apply method assigns the new property to the inspected object.
When subtyping this class, you should redefine only the methods getOriginalValue and applyValue, which are used in the get and apply methods respectively.
A preview accessor can be set to the accessor. When the accessor is initialized, the preview accessor is also initialized with the same value. Likewise, when the accessor is set to a value, the preview accessor is assigned the same value. Using a preview accessor makes it possible to reflect changes to the accessor in another object, such as a graphic object in an inspector panel.

Member Enumeration Documentation

enum IlvStIPropertyAccessor::PropertyStatus

This enumeration type defines the status of the property stored in the object. This status is set when the accessor is initialized via the get method.

Enumerator
Uninitialized	The property is uninitialized.
Inaccessible	The property is inaccessible.
ReadWrite	The property is readable and writable.
ReadOnly	The property is read only.

Constructor & Destructor Documentation

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

protected

Initializes an instance of IlvStIPropertyAccessor.

Parameters

name	The accessor name.
updateMode	The update mode.
buildMode	The build mode.

Member Function Documentation

virtual void IlvStIPropertyAccessor::applyValue ( IlvStIProperty * prop )

protectedvirtual

Called to change the property of the inspected object.

Is called by the apply method to change the property of the inspected object. Because the apply method performs internal operations, such as handling the building mode, we recommend that you redefine the applyValue method instead of the apply method.

Parameters

prop	The new value.

Reimplemented in IlvStIGraphicContainerAccessor, and IlvStIInspectedObjectAccessor.

virtual IlvStIError* IlvStIPropertyAccessor::check ( ) const

virtual

Validates the accessor value.

Returns: An error if the current inspected value of the accessor is not available. Otherwise, it returns 0.

Reimplemented from IlvStIAccessor.

virtual IlvStIError* IlvStIPropertyAccessor::checkValue ( const IlvStIProperty * prop ) const

virtual

Checks the value for a property.

Tests whether the property provided as the parameter is valid. If not, it generates an error. If a validator has been set, it is used by default. Otherwise, the method does nothing.

Parameters

prop	The property.

Returns: 0 if no error occurs, otherwise returns an error.

virtual IlvStIProperty* IlvStIPropertyAccessor::copyProperty ( const IlvStIProperty * property )

protectedvirtual

Called to copy the property when the accessor is in copy mode.

Is called by the get method to copy the property provided as the parameter when the accessor is in copy mode (see IlvStIAccessor::BuildMode). By default, this function calls the copy function of the property and returns the result.

Parameters

property The property.

Returns: A copy of the property.

virtual IlvStIProperty* IlvStIPropertyAccessor::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 in IlvStICombinedAccessor, and IlvStIPropertiesAccessor.

virtual IlvStIProperty* IlvStIPropertyAccessor::get ( )

virtual

Returns the object's property.

Returns: The object's property, which is stored in the IlvStIProperty object.

Reimplemented in IlvStIPropertiesAccessor.

virtual IlvStIProperty* IlvStIPropertyAccessor::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 in IlvStIGraphicContainerAccessor, IlvStICombinedAccessor, IlvStIInspectedObjectAccessor, and IlvStIPropertiesAccessor.

IlvStIPrecondition* IlvStIPropertyAccessor::getPrecondition ( ) const

Returns the precondition.

Returns: The precondition used to test whether the object property can be accessed.

IlvStIPropertyAccessor* IlvStIPropertyAccessor::getPreviewAccessor ( ) const

Returns the preview accessor.

Returns: The preview accessor.

PropertyStatus IlvStIPropertyAccessor::getPropertyStatus ( ) const

Returns the status of the current stored property.

Returns: The status of the current stored property.

virtual IlBoolean IlvStIPropertyAccessor::getValidateOnApply ( ) const

protectedvirtual

Returns IlTrue if validation is performed.

Returns: IlTrue if validation is performed when apply is called. If it returns IlFalse, validation is performed as soon as the changes are made.

IlvStIValidator* IlvStIPropertyAccessor::getValidator ( ) const

Returns the validator used by the checkValue method.

Returns: The validator used by the checkValue method

virtual IlBoolean IlvStIPropertyAccessor::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 IlvStIAccessor.

Reimplemented in IlvStICombinedAccessor, and IlvStIPropertiesAccessor.

virtual IlBoolean IlvStIPropertyAccessor::isReadOnly ( ) const

virtual

Returns IlTrue if the current property is read-only.

Returns: IlTrue if the current property is read-only.

virtual IlBoolean IlvStIPropertyAccessor::isReadWrite ( ) const

virtual

Returns IlTrue if the current property has read and write access.

Returns: IlTrue if the current property has read and write access.

virtual void IlvStIPropertyAccessor::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

prop	The new property.
editor	The editor which must be not reinitialized.

Reimplemented in IlvStICombinedAccessor, and IlvStIPropertiesAccessor.

void IlvStIPropertyAccessor::setPrecondition ( IlvStIPrecondition * precond )

Sets the precondition.

Sets the precondition used to test whether the object property can be accessed. If the precondition was already set, it is destroyed and replaced with the new one.

Parameters

precond The new precondition.

void IlvStIPropertyAccessor::setPreviewAccessor ( IlvStIPropertyAccessor * accessor )

Sets the preview accessor.

Parameters

accessor The accessor which uses the current accessor like preview accessor.

void IlvStIPropertyAccessor::setValidator ( IlvStIValidator * validator )

Sets the validator to the accessor.

Parameters

validator The validator to the accessor.
