void lv_flex_init(void)

Initialize a flex layout to default values

void lv_obj_set_flex_flow(lv_obj_t *obj, lv_flex_flow_t flow)

Set how the item should flow

Parameters:

• obj – pointer to an object. The parent must have flex layout else nothing will happen.

• flow – an element of lv_flex_flow_t.

void lv_obj_set_flex_align(lv_obj_t *obj, lv_flex_align_t main_place, lv_flex_align_t cross_place, lv_flex_align_t track_cross_place)

Set how to place (where to align) the items and tracks

Parameters:

• obj – pointer to an object. The parent must have flex layout else nothing will happen.

• main_place – where to place the items on main axis (in their track). Any value of lv_flex_align_t.

• cross_place – where to place the item in their track on the cross axis. LV_FLEX_ALIGN_START/END/CENTER

• track_cross_place – where to place the tracks in the cross direction. Any value of lv_flex_align_t.

void lv_obj_set_flex_grow(lv_obj_t *obj, uint8_t grow)

Sets the width or height (on main axis) to grow the object in order fill the free space

Parameters:

• obj – pointer to an object. The parent must have flex layout else nothing will happen.
