The Razred Java BoxLayout se uporablja za razporeditev komponent navpično ali vodoravno. V ta namen razred BoxLayout nudi štiri konstante. So naslednji:

Opomba: razred BoxLayout je v paketu javax.swing.

Polja razreda BoxLayout

javni statični končni int X_AXIS:Poravnava komponent je vodoravna od leve proti desni.javni statični final int Y_AXIS:Poravnava komponent je navpična od zgoraj navzdol.javni statični končni int LINE_AXIS:Poravnava komponent je podobna načinu poravnave besed v vrstici, ki temelji na lastnosti ComponentOrientation vsebnika. Če je lastnost ComponentOrientation vsebnika vodoravna, so komponente poravnane vodoravno; sicer so komponente poravnane navpično. Za horizontalne orientacije imamo dva primera: od leve proti desni in od desne proti levi. Če je vrednost lastnosti ComponentOrientation vsebnika od leve proti desni, so komponente upodobljene od leve proti desni, pri desni proti levi pa je upodobitev komponent tudi od desne proti levi. V primeru navpične orientacije so komponente vedno upodobljene od zgoraj navzdol.javni statični končni int PAGE_AXIS:Poravnava komponent je podobna načinu namestitve vrstic besedila na stran, ki temelji na lastnosti ComponentOrientation vsebnika. Če je lastnost ComponentOrientation vsebnika vodoravna, so komponente poravnane navpično; v nasprotnem primeru so komponente poravnane vodoravno. Za horizontalne orientacije imamo dva primera: od leve proti desni in od desne proti levi. Če je vrednost lastnosti ComponentOrientation vsebnika tudi od leve proti desni, so komponente upodobljene od leve proti desni, pri desni proti levi pa je upodobitev komponent od desne proti levi. V primeru navpične orientacije so komponente vedno upodobljene od zgoraj navzdol.
