KWinFT, fereko ea KWin e shebaneng le Wayland, e hlahisitsoe

Roman Gilg, ho kenya letsoho nts'etsopele ea KDE, Wayland, Xwayland le X Server, tsebisoa morero KWinFT (KWin Fast Track), ho nts'etsapele mookameli oa lifensetere tse bonolo le tse sebelisoang habonolo bakeng sa Wayland le X11 ho latela codebase. Kwin. Ho phaella ho mookameli oa fensetere, morero o boetse o hlahisa laebrari wrapland ka ho kenya ts'ebetsong ea tlamo holim'a libwayland bakeng sa Qt/C++, nts'etsopele e tsoelang pele KWayland, empa e lokolotsoe ho tloha ho Qt. Khoutu e ajoa tlasa laesense ea GPLv2 le LGPLv2.

Sepheo sa morero ke ho sebelisa KWin le KWayland hape
mahlale a sejoale-joale le mekhoa ea nts'etsopele e u lumellang ho potlakisa nts'etsopele ea projeke, ho fetola khoutu, ho eketsa ntlafatso le ho nolofatsa tlatsetso ea lits'ebetso tsa mantlha, tseo ho thata ho li kopanya le KWin ka sebopeho sa eona sa hajoale. KWinFT le Wrapland li ka sebelisoa ho nkela KWin le KWayland sebaka ka mokhoa o se nang seam, empa ha li fokotsoe ke ho notleloa ha KWin ea lihlahisoa tse ngata moo ho boloka tumellano e felletseng e leng ntho e tlang pele e thibelang boqapi ho tsoela pele.

Ka KWinFT, bahlahisi ba na le letsoho la mahala la ho leka likarolo tse ncha ha ba ntse ba boloka botsitso ka ho sebelisa mekhoa ea morao-rao ea ntlafatso. Ka mohlala, ho hlahloba khoutu ea KWinFT, ho sebelisoa mokhoa o tsoelang pele oa ho kopanya, ho kenyelletsa le ho netefatsa ho sebelisa li-linters tse fapaneng, ho hlahisa likopano ka mokhoa o itekanetseng le tlhahlobo e tsoetseng pele. Mabapi le nts'etsopele ea ts'ebetso, sepheo sa mantlha sa KWinFT e tla ba ho fana ka ts'ehetso ea protocol ea boleng bo holimo le e felletseng

Har'a lintlafatso tsa liteko tse seng li kentsoe ho KWinFT ke:

• Ts'ebetso ea ho kopanya e entsoe bocha, e ntlafalitseng haholo phepelo ea litaba tse tsamaisang X11 le Wayland. Ho feta moo, sebali sa nako se kentsoe ho fokotsa tieho lipakeng tsa ho etsa setšoantšo le ponts'o ea sona skrineng.

• Ts'ehetso e felletseng ea tlhahiso e potolohang le ea seipone bakeng sa linako tse thehiloeng ho Wayland.

Wrapland e fana ka sebopeho sa lenaneo la setaele sa Qt se fanang ka phihlello ea mesebetsi ea libwayland ka mokhoa o bonolo ho o sebelisa mererong ea C++. Wrapland qalong e ne e reretsoe ho ntlafatsoa joalo ka fereko ea KWayland, empa ka lebaka la boemo bo sa khotsofatseng ba khoutu ea KWayland, joale e nkuoa e le morero oa ho nchafatsa KWayland ka botlalo. Phapang ea bohlokoahali lipakeng tsa Wrapland le KWayland ke hore ha e sa tlamelloa ho Qt mme e ka sebelisoa ka thoko ntle le ho kenya Qt. Nakong e tlang, Wrapland e ka sebelisoa e le laebrari ea bokahohle e nang le C ++ API, e felisang tlhokahalo ea hore bahlahisi ba sebelise libwayland C API.
