C++ (Cpp) G_TYPE_IS_DERIVABLE示例

示例#1

文件： thunarx-provider-plugin.c 项目： Distrotech/Thunar

/**
 * thunarx_provider_plugin_register_type:
 * @plugin      : a #ThunarxProviderPlugin.
 * @type_parent : the type for the parent class.
 * @type_name   : name for the type.
 * @type_info   : type information structure.
 * @type_flags  : flags field providing details about the type.
 *
 * Looks up or registers a type that is implemented with a particular type @plugin. If a type with name @type_name
 * was previously registered, the #GType identifier for the type is returned, otherwise the type is newly registered,
 * and the resulting #GType identifier returned.
 *
 * When reregistering a type (typically because a module is unloaded then reloaded, and reinitialized), module and
 * @type_parent must be the same as they were previously. 
 *
 * Return value: the new or existing type id.
