Detailed Description

This is the base class and interface for property groups.

This class itself is abstract and derived from WPropertyBase. So if you create a group of properties, this ensures that your group is a property itself. This interface defines no way to add, remove or edit the property list itself. This allows the deriving class to prohibit modifications and to provide a custom interface, or even model-controller like implementations.

Another advantage is, that the GUI implementations which support WPropertyGroupBase can display your custom properties directly.

typedef PropertyContainerType::const_iterator WPropertyGroupBase::PropertyConstIterator

The const iterator type of the container.

Reimplemented in WPropertyGroup.

Definition at line 69 of file WPropertyGroupBase.h.

typedef std::vector< boost::shared_ptr< WPropertyBase > > WPropertyGroupBase::PropertyContainerType

For shortening: a type defining a shared vector of WSubject pointers.

typedef PropertyContainerType::iterator WPropertyGroupBase::PropertyIterator

The iterator type of the container.

Reimplemented in WPropertyGroup.

Constructor & Destructor Documentation

WPropertyGroupBase::WPropertyGroupBase ( std::string  name,
std::string  description 
)

Constructor.

Creates an empty list of properties.

Parameters:
namethe name of the property group. The GUI is using this name for naming the tabs/group boxes
descriptionthe description of the group.

Definition at line 42 of file WPropertyGroupBase.cpp.

References WSharedObject< T >::getChangeCondition(), m_properties, and WPropertyBase::m_updateCondition.

WPropertyGroupBase::WPropertyGroupBase ( const WPropertyGroupBase from) [explicit]

Copy constructor.

Creates a deep copy of this property. As boost::signals2 and condition variables are non-copyable, new instances get created. The subscriptions to a signal are LOST as well as all listeners to a condition. The conditions you can grab using getValueChangeConditon and getCondition are not the same as in the original! This is because the class corresponds to the observer/observable pattern. You won't expect a clone to fire a condition if a original flag is changed (which after cloning is completely decoupled from the clone).

Notes:
the properties inside this list are also copied deep
Parameters:
fromthe instance to copy.

WPropertyGroupBase::~WPropertyGroupBase ( ) [virtual]

Destructor.

Member Function Documentation

void WPropertyGroupBase::addArbitraryProperty ( WPropertyBase::SPtr  prop) [protected]

Insert the specified property into the list.

This method is protected. It is a convenience method for deriving classes to add properties without the need to update several conditions and similar.

Parameters:
propthe property to add

bool WPropertyGroupBase::existsProperty ( std::string  name) [virtual]

Helper function that finds a property by its name.

Use this method to find out whether the property exists or not, since findProperty throws an exception.

Parameters:
namename of searched property.
Returns:
Answer to the question whether the property exists.

Definition at line 140 of file WPropertyGroupBase.cpp.

References findProperty().

boost::shared_ptr< WPropertyBase > WPropertyGroupBase::findProperty ( std::string  name) const [virtual]

Searches the property with a given name.

It does not throw any exception. It simply returns NULL if it can't be found.

Parameters:
namethe name of the property to search
Returns:
the property or NULL if not found.

boost::shared_ptr< WPropertyBase > WPropertyGroupBase::findProperty ( const WPropertyGroupBase *const  props,
std::string  name 
) const [protected, virtual]

Helping function to find a property inside a specific group.

It does not recursively find properties nested inside other property groups.

Parameters:
propsthe group to search in. This is not a shared pointer since it is not needed. It simply can't happen that it is freed during findProperty as it is contained in this or a nested properties instance.
namethe name of the property inside THIS group.
Returns:
the property if found, else NULL.

References WSharedObject< T >::getReadTicket(), and m_properties.

WPropertyGroupBase::PropertySharedContainerType::ReadTicket WPropertyGroupBase::getProperties ( ) const [virtual]

Returns a read ticket for read-access to the list of properties.

Returns:
the read ticket.

Definition at line 194 of file WPropertyGroupBase.cpp.

References WSharedObject< T >::getReadTicket(), and m_properties.

boost::shared_ptr< WPropertyBase > WPropertyGroupBase::getProperty ( std::string  name) [virtual]

Function searches the property.

If it does not exists, it throws an exception.

Parameters:
namethe name of the property
Returns:
a WProperty object

References findProperty().

WPropertyGroupBase::PropertySharedContainerType::ReadTicket WPropertyGroupBase::getReadTicket ( ) const [virtual]

Returns an read ticket for the properties.

This, and only this, has to be used for external iteration of properties.

See also:
WSharedObjectTicketRead
Returns:
the read ticket.

bool WPropertyGroupBase::propNamePredicate ( boost::shared_ptr< WPropertyBase prop1,
boost::shared_ptr< WPropertyBase prop2 
) const [protected]

Compares the names of two properties and returns true if they are equal.

Parameters:
prop1the first prop.
prop2the second prop.
Returns:
Are the names of the two properties equal?
