Razred Java FlowLayout se uporablja za razporeditev komponent v vrstico, eno za drugo (v toku). To je privzeta postavitev programčka ali plošče.

Konstruktorji razreda FlowLayout

FlowLayout():ustvari postavitev toka s sredinsko poravnavo in privzeto vodoravno in navpično vrzeljo 5 enot.FlowLayout (int align):ustvari postavitev toka z dano poravnavo in privzeto vodoravno in navpično vrzeljo 5 enot.FlowLayout(int align, int hgap, int vgap):ustvari postavitev toka z dano poravnavo ter dano vodoravno in navpično režo.

Primer razreda FlowLayout: uporaba konstruktorja FlowLayout().
