GObjecttype_ensure
since: 2.34
Declaration [src]
void
g_type_ensure (
GType type
)
Description [src]
Ensures that the indicated type has been registered with the
type system, and its _class_init() method has been run.
Typically, calling the type’s _get_type() method (or using the
corresponding macro) will take care of this. In situations where a
type is looked up dynamically, however, you may need to explicitly call
g_type_ensure() to ensure expected types are registered before the
first lookup. This can happen when using custom widgets from a GTK
.ui file, for example.
Historically, _get_type() methods have sometimes been marked as
G_GNUC_CONST. This is incorrect, as the
first call to a _get_type() method has side-effects. These
annotations should be removed, as they can cause code to be optimized
out in unexpected ways by the compiler.
