lv_obj_get_style_prop_internal

Internal implementation of lv_obj_get_style_prop Does not do any argument checking

lv_style_value_t lv_obj_get_style_prop_internal(const lv_obj_t *obj, lv_part_t part, lv_style_prop_t prop)

Name	Type
`obj`	`const lv_obj_t *`
`part`	`lv_part_t`
`prop`	`lv_style_prop_t`

private/core/lv_obj_style_private.h:54function

lv_obj_style_init

Initialize the object related style manager module. Called by LVGL in lv_init()

void lv_obj_style_init(void)

private/core/lv_obj_style_private.h:60function

lv_obj_style_deinit

Deinitialize the object related style manager module. Called by LVGL in lv_deinit()

void lv_obj_style_deinit(void)

private/core/lv_obj_style_private.h:70function

lv_obj_style_create_transition

Used internally to create a style transition

void lv_obj_style_create_transition(lv_obj_t *obj, lv_part_t part, lv_state_t prev_state, lv_state_t new_state, const lv_obj_style_transition_dsc_t *tr_dsc)

Name	Type
`obj`	`lv_obj_t *`
`part`	`lv_part_t`
`prev_state`	`lv_state_t`
`new_state`	`lv_state_t`
`tr_dsc`	`const lv_obj_style_transition_dsc_t *`

private/core/lv_obj_style_private.h:84function

lv_obj_style_state_compare

Used internally to compare the appearance of an object in 2 states

lv_style_state_cmp_t lv_obj_style_state_compare(lv_obj_t *obj, lv_state_t state1, lv_state_t state2, lv_part_t *changed_part)

Name	Type	Description
`obj`	`lv_obj_t *`
`state1`	`lv_state_t`
`state2`	`lv_state_t`
`changed_part`	`lv_part_t *`	optional (may be NULL) out-param. Receives the part that the differing styles belong to, or `LV_PART_ANY` if more than one part differs (or none does). Lets the caller scope the refresh to a single part when possible.

private/core/lv_obj_style_private.h:92function

lv_obj_update_layer_type

Update the layer type of a widget bayed on its current styles. The result will be stored in obj->spec_attr->layer_type

void lv_obj_update_layer_type(lv_obj_t *obj)

Name	Type	Description
`obj`	`lv_obj_t *`	the object whose layer should be updated

private/core/lv_obj_style_private.h:105function

lv_obj_style_apply_color_filter_internal

Internal implementation of lv_obj_style_apply_color_filter Does not do any argument checking

lv_style_value_t lv_obj_style_apply_color_filter_internal(const lv_obj_t *obj, lv_part_t part, lv_style_value_t v)

Name	Type
`obj`	`const lv_obj_t *`
`part`	`lv_part_t`
`v`	`lv_style_value_t`

private/core/lv_obj_style_private.h:113function

Update the cached blur status of a widget based on its current styles and state, and maintain the global count of widgets with blur (blur_obj_cnt in lv_global_t). The result will be stored in obj->has_blur.

void lv_obj_update_blur_status(lv_obj_t *obj)

Name	Type	Description
`obj`	`lv_obj_t *`	the object whose blur status should be updated
