Description
A draw descriptor that can be modified to changed what LVGL will draw. Set only for rectangle-like parts.
A draw descriptor that can be modified to changed what LVGL will draw. Set only for text-like parts.
A draw descriptor that can be modified to changed what LVGL will draw. Set only for line-like parts.
A draw descriptor that can be modified to changed what LVGL will draw. Set only for image-like parts.
A draw descriptor that can be modified to changed what LVGL will draw. Set only for arc-like parts.
A point calculated during drawing. E.g. a point of chart or the center of an arc.
A point calculated during drawing. E.g. a point of chart.
char *
A text calculated during drawing. Can be modified. E.g. tick labels on a chart axis.
uint32_t
Size of the text buffer containing null-terminated text string calculated during drawing.
uint32_t
The index of the part. E.g. a button's index on button matrix or table cell index.
int32_t
A value calculated during drawing. E.g. Chart's tick line value.
const void *
A pointer the identifies something in the part. E.g. chart series.
