Na fara da bayanin yadda kayan kwalliyar taga suke aiki a KWin 4. KWin shine ake kira da sake-iyaye na masu kula da taga. Wannan yana nufin cewa taga da X11 ke sarrafawa an saka shi cikin wani taga na X11 wanda ke ba da taga taga. A KWin muna amfani da QWidget don firam ɗin taga. Saboda haka an kuma taƙaita mu zuwa ga abin da QWidget ke samar mana ... Maganinmu shi ne katse duk al'amuran zanen kayan ado a cikin QWidget kuma mu danne shi, haifar da wani sabon abu na mawaƙin kuma a cikin matakin da aka ba da garantin ado na hoton ɗan lokaci wanda a lokacin an kofe shi a cikin zane.

Adon taga taken Breeze ya dogara da injin jigon Aurorae. Tunda nine jagorar marubucin Aurorae zan iya buga shi akan wannan shafin yanar gizon ba tare da jin haushi game da shi ba was An tsara Aurorae don zama mai sauƙin ƙirƙirar kayan ado da kuma amfani da sabbin abubuwan fasalin translucency. Kasancewa mafita wacce za a iya amfani da ita azaman adon tsoho, amma ba shine burin su ba. Manufar ita ce ta ba da damar masu amfani waɗanda ke son tsara wannan fasalin, yayin da yawancin masu amfani za su iya amfani da jigogi na asali waɗanda suke da sauri. Aurorae bata taɓa yin sauri ba kuma ba zata yi sauri ba.

Yanzu a cikin KWin 5, amfani da QML shine babbar matsalar da ke sa Aurorae wahalar amfani dashi. QtQuick yana amfani da Scenegraph kuma yana amfani da QWindows maimakon QWidget. Hakan bummer ne ga API ɗin mu na QWidget. Mun daidaita amfani na ciki don tallafawa kayan kwalliyar QWindows, amma wannan hanya ce mai wahala kasancewar akwai bambance-bambance a cikin halayen windows. Tunda yanzu ba ta dogara da QWidget ba, tarkon taronmu na fenti ya karye kuma muna buƙatar sabon bayani game da shi. Kuma wannan maganin yafi na baya muni saboda QtQuick a halin yanzu yana aiki ta hanyar OpenGL. Saboda iyakoki a cikin aikace-aikacen OpenGL Qt (ana iya magance su a cikin Qt 5.4) wanda ba za mu iya raba tare da yanayin OpenGL da QtQuick ke amfani da shi ba ... Wannan ba kawai wani babban abu bane yayin kwafin abun ciki daga GPU zuwa RAM da sake dawowa zuwa GPU, kuna rasa ƙwaƙwalwar ajiya da yawa. Idan kuma aka ƙara girman taga ba kawai taken take ba, amma duk taga. Kuma akwai wancan sama don kowane taga.

Wannan kawai zai iya sa Aurorae ya zama mara amfani. A halin yanzu ina amfani da taken Breeze kuma KWin yana buƙatar fiye da 200MB na RAM - ba karɓaɓɓe sosai ba. Amma lamarin ya fi haka muni. Tare da QWindows ba zamu iya sanin waɗanne yankunan da aka sabunta ba. Don haka lokacin da, alal misali, aka sabunta maɓallin dole ne mu sake fentin dukkan taga, gami da cikakken kwafin abubuwan adon. Wannan musamman a cikin yanayin motsa jiki babbar matsala ce.
