Haiku avatud operatsioonis\u00fcsteemi arendajad, kes j\u00e4tkavad BeOSi ideede arendamist, on valmistanud ette algse rakenduse kihist, et tagada \u00fchilduvus Xlibi raamatukoguga, mis v\u00f5imaldab k\u00e4ivitada X11-rakendusi Haikus ilma X-serveri kasutamiseta. Kihist on realiseeritud Xlibi funktsioonide emuleerimise kaudu, muutes kutseid k\u00f5rgetasemeliseks Haiku graafiliseks API-ks. <\/p>\n

Praeguses vormis pakub kihist enamik tavaliselt kasutatavaid Xlibi programmistandardeid, kuid m\u00f5ningad kutseid on endiselt asendatud stubidega. Kihist v\u00f5imaldab GTK raamatukogu baasil rakenduste kompileerimist ja k\u00e4ivitamist, kuid elementide paigutuse kvaliteet akendes vajab veel t\u00e4iendavat t\u00f6\u00f6d. Klaviatuuri ja hiireklikkide sisendi t\u00f6\u00f6tlemine pole veel t\u00f6\u00f6tav (lisatud on ainult hiire liikumise s\u00fcndmuse t\u00f6\u00f6tlemine). <\/p>\n

Qt-teegi tugi Haiku's rakendati varem, luues native Qt porta, mis t\u00f6\u00f6tas Haiku API peal. Kuid GTK toetamiseks peetakse X11 emuleerimise kasutamist eelistatavamaks, kuna GTK sisemused pole nii h\u00e4sti abstraktsioonitud ja eraldi GTK tagaosa loomine Haiku'le n\u00f5uaks m\u00e4rkimisv\u00e4\u00e4rseid ressursse. V\u00e4ljap\u00e4\u00e4suna kaaluti X11 portimise v\u00f5imalust Haiku'le, kuid selline l\u00e4henemine tunnistati olevat ebat\u00f5hus olukordades, kus X11 API saab rakendada otseselt Haiku API peal. X11 on valitud, kuna see on vana stabiliseeritud ja muutumatud protokoll, samas kui Waylandiga j\u00e4tkuvad eksperimendid, on vajalik luua oma serveri rakendus ning mitte k\u00f5ik vajalikud protokolli laiendused on l\u00f5plikult kinnitatud.serverile<\/a> Rakenduste k\u00e4ivitamisel l\u00e4bi lihtsamaid liideseid nagu Tcl\/Tk ja wxWidgets on samuti t\u00e4heldatud veel lahendamata probleeme, kuid v\u00e4limus on juba l\u00e4hemal normaalsusele:

Tcl\/Tk ja wxWidgets kaudu k\u00e4ivitamisel on t\u00e4heldatud ka lahendamata probleeme, kuid v\u00e4limus on juba normaalsemale l\u00e4hemal:

Tulet meelde, et projekt Haiku loodi 2001. aastal vastusena BeOS operatsioonis\u00fcsteemi arendamise l\u00f5petamisele ning arenes OpenBeOS nime all, kuid 2004. aastal nimetati see \u00fcmber seoses BeOS kaubam\u00e4rgi kasutamisega seotud n\u00f5uetega. S\u00fcsteem p\u00f5hineb otse BeOS 5 tehnoloogiatel ning on suunatud binaarse \u00fchilduvuse saavutamisele selle operatsioonis\u00fcsteemi rakendustega. Enamiku Haiku operatsioonis\u00fcsteemi l\u00e4htekood on saadaval vabavaralise MIT litsentsi alusel, v\u00e4lja arvatud m\u00f5ned teegid, meediatekooderid ja komponendid, mis on laenatud teistelt projektidelt. <\/p>\n

S\u00fcsteem on keskendunud personaalarvutitele, kasutades oma k\u00e4rki, mis p\u00f5hineb h\u00fcbriidarkitektuuril, mis on optimeeritud kasutaja toimingutele kiirele reageerimisele ja mitme l\u00f5ime rakenduste efektiivsele t\u00e4itmisele. Failis\u00fcsteemina kasutatakse OpenBFS-i, mis toetab laiendatud failiatriibuteid, logimist, 64-bitiseid n\u00e4itajaid, meta-siltide hoidmise toetamist (iga faili jaoks saab salvestada atribuute vormis v\u00f5tme=v\u00e4\u00e4rtus, mis muudab failis\u00fcsteemi sarnaseks andmebaasiga) ja spetsiaalseid indekse, mis kiirendavad nende p\u00f5hjal p\u00e4ringute tegemist. Kaustade struktuuri korraldamiseks kasutatakse \u201eB+ puu\u201c puid. Haiku koodi hulka kuuluvad BeOS-i failihaldur Tracker ja Deskbar paneel, mille allikaid avati BeOS-i arendamise l\u00f5petamisel.
