Summary

Functions

widgets/line/lv_line.h:57function

lv_line_set_points

Set an array of points. The line object will connect these points.

void lv_line_set_points(lv_obj_t *obj, const lv_point_precise_t points[], uint32_t point_num)

Name	Type	Description
`obj`	`lv_obj_t *`	pointer to a line object
`points`	`const lv_point_precise_t`	an array of points. Only the address is saved, so the array needs to be alive while the line exists
`point_num`	`uint32_t`	number of points in 'point_a'

widgets/line/lv_line.h:65function

lv_line_set_points_mutable

Set a non-const array of points. Identical to lv_line_set_points except the array may be retrieved by lv_line_get_points_mutable.

void lv_line_set_points_mutable(lv_obj_t *obj, lv_point_precise_t points[], uint32_t point_num)

Name	Type	Description
`obj`	`lv_obj_t *`	pointer to a line object
`points`	`lv_point_precise_t`	a non-const array of points. Only the address is saved, so the array needs to be alive while the line exists.
`point_num`	`uint32_t`	number of points in 'point_a'

widgets/line/lv_line.h:74function

lv_line_set_y_invert

Enable (or disable) the y coordinate inversion. If enabled then y will be subtracted from the height of the object, therefore the y = 0 coordinate will be on the bottom.

void lv_line_set_y_invert(lv_obj_t *obj, bool en)

Name	Type	Description
`obj`	`lv_obj_t *`	pointer to a line object
`en`	`bool`	true: enable the y inversion, false:disable the y inversion
