Properties API Reference (obs_properties_t) =========================================== Properties are used to enumerate available settings for a libobs object. Typically this is used to automatically generate user interface widgets, though can be used to enumerate available and/or valid values for specific settings as well. .. type:: obs_properties_t Properties object (not reference counted). .. type:: obs_property_t A property object (not reference counted). .. code:: cpp #include General Functions ----------------- .. function:: obs_properties_t *obs_properties_create(void) :return: A new properties object. --------------------- .. function:: obs_properties_t *obs_properties_create_param(void *param, void (*destroy)(void *param)) Creates a new properties object with specific private data *param* associated with the object, and is automatically freed with the object when the properties are destroyed via the *destroy* function. :return: A new properties object. --------------------- .. function:: void obs_properties_destroy(obs_properties_t *props) --------------------- .. function:: void obs_properties_set_flags(obs_properties_t *props, uint32_t flags) uint32_t obs_properties_get_flags(obs_properties_t *props) :param flags: 0 or a bitwise OR combination of one of the following values: - OBS_PROPERTIES_DEFER_UPDATE - A hint that tells the front-end to defers updating the settings until the user has finished editing all properties rather than immediately updating any settings --------------------- .. function:: void obs_properties_set_param(obs_properties_t *props, void *param, void (*destroy)(void *param)) void *obs_properties_get_param(obs_properties_t *props) Sets custom data associated with this properties object.
