TypeClass

An opaque structure used as the base of all classes.

Constructors

this
this(GTypeClass* gTypeClass)

Sets our main struct and passes it to the parent class.

Members

Functions

getPrivate
void* getPrivate(GType privateType)
getStruct
void* getStruct()

the main Gtk struct as a void*

getTypeClassStruct
GTypeClass* getTypeClassStruct()

Get the main Gtk struct

peekParent
TypeClass peekParent()

This is a convenience function often needed in class initializers. It returns the class structure of the immediate parent type of the class passed in. Since derived classes hold a reference count on their parent classes as long as they are instantiated, the returned class will always exist.

unref
void unref()

Decrements the reference count of the class structure being passed in. Once the last reference count of a class has been released, classes may be finalized by the type system, so further dereferencing of a class pointer after g_type_class_unref() are invalid.

unrefUncached
void unrefUncached()

A variant of g_type_class_unref() for use in #GTypeClassCacheFunc implementations. It unreferences a class without consulting the chain of #GTypeClassCacheFuncs, avoiding the recursion which would occur otherwise.

Static functions

addPrivate
void addPrivate(void* gClass, size_t privateSize)

Registers a private structure for an instantiatable type.

adjustPrivateOffset
void adjustPrivateOffset(void* gClass, int* privateSizeOrOffset)
doref
TypeClass doref(GType type)

Increments the reference count of the class structure belonging to @type. This function will demand-create the class if it doesn't exist already.

getInstancePrivateOffset
int getInstancePrivateOffset(void* gClass)

Gets the offset of the private data for instances of @g_class.

peek
TypeClass peek(GType type)

This function is essentially the same as g_type_class_ref(), except that the classes reference count isn't incremented. As a consequence, this function may return %NULL if the class of the type passed in does not currently exist (hasn't been referenced before).

peekStatic
TypeClass peekStatic(GType type)

A more efficient version of g_type_class_peek() which works only for static types.

Variables

gTypeClass
GTypeClass* gTypeClass;

the main Gtk struct
