Variable management
Members functions related to initial instance variables management.

gd::VariablesContainer &	GetVariables ()

Others properties management
Members functions related to exposing others properties of the instance. Note Extensions writers: even if we can define new types of object by inheriting from gd::Object class, we cannot define new gd::InitialInstance classes. However, objects can store custom properties for their associated initial instances. When the IDE want to get the custom properties, it will call `GetCustomProperties` and `UpdateCustomProperty` methods. These methods are here defined to forward the call to the gd::Object associated to the gd::InitialInstance (by looking at the value returned by GetObjectName()). See also gd::Object

	Return a map containing the properties names (as keys) and their values. More...

bool	UpdateCustomProperty (const gd::String &name, const gd::String &value, gd::ObjectsContainer &globalObjectsContainer, gd::ObjectsContainer &objectsContainer)
	Update the property called name with the new value. More...

double	GetRawDoubleProperty (const gd::String &name) const
	Get the value of a double property stored in the instance. More...

const gd::String &	GetRawStringProperty (const gd::String &name) const
	Get the value of a string property stored in the instance. More...

void	SetRawDoubleProperty (const gd::String &name, double value)
	Set the value of a double property stored in the instance.

void	SetRawStringProperty (const gd::String &name, const gd::String &value)
	Set the value of a string property stored in the instance.

Saving and loading
Members functions related to serialization.
virtual void	SerializeTo (SerializerElement &element) const
	Serialize instances container.

virtual void	UnserializeFrom (const SerializerElement &element)
	Unserialize the instances container.

InitialInstance &	ResetPersistentUuid ()
	Reset the persistent UUID used to recognize the same initial instance between serialization.

Member Function Documentation

◆ Clone()

InitialInstance* gd::InitialInstance::Clone ( ) const

inline

Must return a pointer to a copy of the object. A such method is needed to do polymorphic copies. Just redefine this method in your derived object class like this:

return new MyInitialInstanceClass(*this);

◆ GetCustomProperties()

std::map< gd::String, gd::PropertyDescriptor > gd::InitialInstance::GetCustomProperties	(	gd::ObjectsContainer &	globalObjectsContainer,
		gd::ObjectsContainer &	objectsContainer
	)

Return a map containing the properties names (as keys) and their values.

Note: Common properties ( name, position... ) do not need to be inserted in this map

◆ GetRawDoubleProperty()

double gd::InitialInstance::GetRawDoubleProperty ( const gd::String & name ) const

Get the value of a double property stored in the instance.

Note: Only use this when GetCustomProperties is too slow (when rendering instances for example).

Returns: the value of the property, or 0 if it does not exists.

◆ GetRawStringProperty()

const gd::String & gd::InitialInstance::GetRawStringProperty ( const gd::String & name ) const

Get the value of a string property stored in the instance.

Note: Only use this when GetCustomProperties is too slow (when rendering instances for example).

Returns: the value of the propety, or an empty string if it does not exists.

◆ GetVariables() [1/2]

gd::VariablesContainer& gd::InitialInstance::GetVariables ( )

inline

Must return a reference to the container storing the instance variables

See also: gd::VariablesContainer

◆ GetVariables() [2/2]

const gd::VariablesContainer& gd::InitialInstance::GetVariables ( ) const

inline

Must return a reference to the container storing the instance variables

See also: gd::VariablesContainer

◆ HasCustomDepth()

bool gd::InitialInstance::HasCustomDepth ( ) const

inline

Return true if the instance has a depth which is different from its object default depth. This is independent from HasCustomSize.

See also: gd::Object

◆ HasCustomSize()

bool gd::InitialInstance::HasCustomSize ( ) const

inline

Return true if the instance has a width/height which is different from its object default width/height. This is independent from HasCustomDepth.

See also: gd::Object

◆ SetHasCustomDepth()

void gd::InitialInstance::SetHasCustomDepth ( bool hasCustomDepth_ )

inline

Set whether the instance has a depth which is different from its object default depth or not. This is independent from SetHasCustomSize.

Parameters

hasCustomSize true if the depth is different from the object's default depth.

See also: gd::Object

◆ SetHasCustomSize()

void gd::InitialInstance::SetHasCustomSize ( bool hasCustomSize_ )

inline

Set whether the instance has a width/height which is different from its object default width/height or not. This is independent from SetHasCustomDepth.

See also: gd::Object

◆ SetLocked()

void gd::InitialInstance::SetLocked ( bool enable = true )

inline

(Un)lock the initial instance.

An instance which is locked cannot be moved with actions in the IDE.

◆ SetSealed()

void gd::InitialInstance::SetSealed ( bool enable = true )

inline

(Un)seal the initial instance.

An instance which is sealed cannot be selected by clicking on it in a layout editor canvas.

◆ UpdateCustomProperty()

bool gd::InitialInstance::UpdateCustomProperty	(	const gd::String &	name,
		const gd::String &	value,
		gd::ObjectsContainer &	globalObjectsContainer,
		gd::ObjectsContainer &	objectsContainer
	)

Update the property called name with the new value.

Returns: false if the property could not be updated.
