LV_ALIGN_OUT alignments

General discussion

Hello,

Trying to understand meaning of alignments that starts with LV_ALIGN_OUT… .

/** Alignments */
enum {
LV_ALIGN_CENTER = 0,
LV_ALIGN_IN_TOP_LEFT,
LV_ALIGN_IN_TOP_MID,
LV_ALIGN_IN_TOP_RIGHT,
LV_ALIGN_IN_BOTTOM_LEFT,
LV_ALIGN_IN_BOTTOM_MID,
LV_ALIGN_IN_BOTTOM_RIGHT,
LV_ALIGN_IN_LEFT_MID,
LV_ALIGN_IN_RIGHT_MID,
LV_ALIGN_OUT_TOP_LEFT,
LV_ALIGN_OUT_TOP_MID,
LV_ALIGN_OUT_TOP_RIGHT,
LV_ALIGN_OUT_BOTTOM_LEFT,
LV_ALIGN_OUT_BOTTOM_MID,
LV_ALIGN_OUT_BOTTOM_RIGHT,
LV_ALIGN_OUT_LEFT_TOP,
LV_ALIGN_OUT_LEFT_MID,
LV_ALIGN_OUT_LEFT_BOTTOM,
LV_ALIGN_OUT_RIGHT_TOP,
LV_ALIGN_OUT_RIGHT_MID,
LV_ALIGN_OUT_RIGHT_BOTTOM,
};

Everything is clear with LV_ALIGN_IN ones:

They are placed as described. But what about LV_ALIGN_OUT ones? They placed somehow out of container? When I should use them?

Hi

See here: http://lvgl.io/docs/latest/en/html/widgets/obj.html#alignment

OUTs can be used if you align not to the parent but to another object. E.g. a button to another button.
