A kasida ta gaba zamuyi dubi zuwa ga Qt Software Development Kit (Katin SDK). Wannan ya hada da Qt Mahaliccin IDE y Qt Framework Libraries tare da cikakkun misalan lamba, a tsakanin sauran abubuwa. Idan kun kasance mai amfani da Ubuntu 19.10 kuma kuna son haɓaka aikace-aikacen GUI tare da Qt, kuna buƙatar shigar da wannan Qt SDK tare da mai tara C ++.
Qt ba yare bane na shirye-shirye ba. Gaskiya ne game da tsarin da aka rubuta a cikin C ++. Wannan tsarin ne don ci gaban aikace-aikacen dandamali don tebur da wayar hannu. Shigar da shi a cikin 19.10 ya ɗan bambanta da yadda aka yi shi a cikin 18.04. Muna buƙatar saita mai tarawa GNU GCC C++ akan Ubuntu 19.10. Bayan saiti, zaku sami cikakke kuma shirye Qt SDK tare da Qt Mahalicci.
Dole ne a ce haka Qt kayan aikin widget ne na kyauta da na budewa don kirkirar hanyoyin musaya na masu amfani. Kazalika aikace-aikacen dandamali yana gudana akan nau'ikan kayan aiki da dandamali na software kamar Gnu / Linux, Windows, macOS, Android tare da kadan ga babu lambar tushe canji.

Qt Mahalicci IDE ne wanda aka tsara shi a cikin C ++, JavaScript da QML wanda wani ɓangare ne na SDK tare da abin da zaku iya haɓaka Interididdigar Mai amfani da Zane (GUI don karancin sunan ta a Turanci) tare da dakunan karatu na Qt. Qt Mahalicci yana ba da kammala lambar fasaha, ingantaccen tsarin taimako, mai warwarewa da kuma hade manyan tsarin sarrafa sigar (misali git ko Bazaar).
Shigar da Qt SDK akan Ubuntu 19.10
Sanya mai tarawa
Mai kira wanda zamu buƙaci ana kiran shi g ++. Za mu iya shigar da shi ta hanyar buɗe tashar (Ctrl + Alt + T) da kuma bugawa a ciki:

Tsarin asali na Qt Mahalicci
Da zarar an gama shigarwa, abu na farko da zamuyi shine fara sabon shirinmu. Gaba za mu yi gungurawa zuwa ga Kayan aiki → menu na zaɓuka.
Yanzu dole ne mu danna kan Kayan Aikin zaɓi. Kammala ta zaɓar da Kit ɗin kit da zaɓi Manual / Desk Kit.
A cikin taga za'a kasance zaɓi mai tarawa, kodayake tsarin zai iya gano shi ta atomatik. Dole ne a ce haka wannan IDE yana buƙatar mai tarawa wanda aka saita azaman g ++ don ginawa da kuma iya nuna sakamakon ayyukanku.
A cikin Sashin "Mai tarawa", zamu iya ganin zaɓi na C ++. Anan ba za mu sami fiye da haka ba zaɓi GCC C ++ 64 kaɗan, idan ba'a riga an zaba ba. Idan ka gama sai kawai ka latsa «Aika ».
Gwajin gwaji
Bayan duk matakan da ke sama, yanzu yakamata mu sami damar fara shirye-shirye tare da Qt. A lokacin shigarwa, Har ila yau mun girka dukkan misalai. Wadannan ya kamata samuwa daga babban shafi na Qt Mahalicci.
Kamar yadda yake tare da lambar lamba, duk darussan dole ne su kasance bayyane kuma akan babban shafin. Don haka samun damar dukansu zai zama mai sauqi.
Don yin gwaji na asali, kawai zamu zaɓi ɗayan misalai daga cikin duk waɗanda za mu same su. To zamu iya tara shi ta hanyar buga Ctrl + R, ko amfani da maɓallin kore '>'.
Ya kamata ya tattara cikin nasara, kodayake muna iya buƙata zaɓi wuri don wannan misali.
Za mu iya zaɓar sa daga maɓallin "Ba a daidaita shi ba”Wanda za a iya gani a hoton da ya gabata.
Wannan maɓallin zai buɗe sabon taga kamar na baya. A ciki zamu ga cikin zaɓi "Gina & Gudu"→"Gina”Alamar jan launi, wannan kuskuren da aka samu a cikin akwati "Gina kundin adireshi". Ba za a ƙara yin abin ba danna maballin "Binciko" kuma zaɓi babban fayil.
Bayan wannan ya kamata mu iya tattara misalin ba tare da kurakurai ba. Don ƙarin bayani, zaku iya tuntuɓar Qt shafin.
