 *  can’t handle.
 * @GTK_BUILDER_ERROR_MISSING_ATTRIBUTE: An attribute that is required by
 *  `GtkBuilder` was missing.
 * @GTK_BUILDER_ERROR_INVALID_ATTRIBUTE: `GtkBuilder` found an attribute that
 *  it doesn’t understand.
 * @GTK_BUILDER_ERROR_INVALID_TAG: `GtkBuilder` found a tag that
 *  it doesn’t understand.
 * @GTK_BUILDER_ERROR_MISSING_PROPERTY_VALUE: A required property value was
 *  missing.
 * @GTK_BUILDER_ERROR_INVALID_VALUE: `GtkBuilder` couldn’t parse
 *  some attribute value.
 * @GTK_BUILDER_ERROR_VERSION_MISMATCH: The input file requires a newer version
 *  of GTK.
 * @GTK_BUILDER_ERROR_DUPLICATE_ID: An object id occurred twice.
 * @GTK_BUILDER_ERROR_OBJECT_TYPE_REFUSED: A specified object type is of the same type or
 *  derived from the type of the composite class being extended with builder XML.
 * @GTK_BUILDER_ERROR_TEMPLATE_MISMATCH: The wrong type was specified in a composite class’s template XML
 * @GTK_BUILDER_ERROR_INVALID_PROPERTY: The specified property is unknown for the object class.
 * @GTK_BUILDER_ERROR_INVALID_SIGNAL: The specified signal is unknown for the object class.
 * @GTK_BUILDER_ERROR_INVALID_ID: An object id is unknown.
 * @GTK_BUILDER_ERROR_INVALID_FUNCTION: A function could not be found. This often happens
 *   when symbols are set to be kept private. Compiling code with -rdynamic or using the
 *   `gmodule-export-2.0` pkgconfig module can fix this problem.
 *
 * Error codes that identify various errors that can occur while using
 * `GtkBuilder`.
