Для тех кто пишет расширения на PyQt/PySide для CG-софтов. Когда я только начинал писать тулзы под Maya (тогда еще версия 2010-2011) мне приходилось ручками ставить PyQt4 под Maya. Даже написал мануалы по установке на своём сайте. Но потом стал доступен из коробки PySide и позже он обновится до PySide2. Для некоторых систем была поддержка PyQt5. И как простому разработчику поддерживать этот зоопарк? Ведь хочется чтобы тул работал на любой версии (вы тоже делали модуль что-то типа import_qt.py?😁) На помощь приходит проект Qt.py который поставил себе цель унифицировать использование Qt-биндингов вне зависимости от среды где запускается код. Те, кто давно пишут на Qt, скорее всего знают этот проект. Он стал стандартом для CG-индустрии и используется в топовых студиях и проектах. Qt․py помогает запускать один и тот же код на разных платформах с разными вариантами Qt-библиотек. Это может быть как интеграция в CG-софт, так и переносимость стендалонов между разными платформами с разными версиями Python. Я решил рассказать о некоторых особенностях работы с этой библиотекой. Сегодня о том, как установить и использовать Qt․py и что это вам даёт. Установка pip install Qt.py Чтобы начать использовать Qt․py в коде достаточно заменить импорт вашего варианта Qt-биндинга на Qt․py from [PySide|PyQt4|PySide2|PyQt5] import QtWidgets => from Qt import QtWidgets Теперь ваш код будет поддерживать любой вариант биндинга Qt в Python. При этом не потребуется использовать if-else конструкции под разные версии. Все вызовы теперь одинаковы. Всё что нужно сделать, это написать его по правилам PySide2. Именно эта версия была взята за основу. Приоритет импорта такой: 1. PySide2 2. PyQt5 3. PySide 4. PyQt4 Что именно загрузилось можно посмотреть в переменной __binding__ >>> import Qt >>> Qt.__binding__ 'PySide2' Приоритет имопрта можно изменить через переменные QT_PREFERRED_BINDING и QT_PREFERRED_BINDING_JSON. Причем под каждый проект оверрайды можно настраивать индивидеально. #qt#libs

October 18, 2021: U.S missionaries, China economy, Robert Durst, India floods, California oil spill October 18, 2021: U.S missionaries, China economy, Robert Durst, India floods, California oil spill 1. A U.S. Christian aid organization said a group of its missionaries had been kidnapped in Haiti, a further sign the Caribbean nation's gangs are growing increasingly brazen amid political and economic crises. 2. China’s economy hit its slowest pace of growth in a year in the third quarter, hurt by power shortages and wobbles in the property sector, highlighting the challenge facing policymakers as they seek to prop up a faltering recovery while reining in the real estate sector. 3. Leaders in the south Indian state of Kerala opened near-overflowing dams on Monday, after at least 22 people died when heavy rains lashed the state over the weekend. 4. Real estate heir Robert Durst, who was sentenced this week to life in prison for murdering a friend in 2000, has COVID and is on a ventilator, his lawyer told the Los Angeles Times. 5. The U.S. Coast Guard boarded a container ship in the Port of Long Beach that dragged its anchor close to a subsea pipeline found to be the source of an oil spill off Orange County, California, it said in a press release. #Haiti #US #Missionaries #China #Economy #RobertDurst #India #floods #Kerala #California #OilSpill #Caribbean #News #Reuters #MorningNews #Headlines Subscribe: http://smarturl.it/reuterssubscribe Reuters brings you the latest business, finance and breaking news video from around the globe.

October 11, 2021: Alaska quake, U.S. and Taliban, AstraZeneca, Prince Andrew, California oil spill October 11, 2021: Alaska quake, U.S. and Taliban, AstraZeneca, Prince Andrew, California oil spill 1. An earthquake of magnitude 6.8 struck the Alaska Peninsula region, the European Mediterranean Seismological Centre said. 2. The United States said on Sunday the first face-to-face meeting between senior U.S. and Taliban officials since the hardline group retook power in Afghanistan was "candid and professional" and that the U.S. side reiterated that the Taliban would be judged on their actions, not just their words. 3. AstraZeneca's experimental COVID-19 drug has helped cut the risk of severe disease or death in a late-stage study, the British drug maker said, a boost to its efforts to develop coronavirus medicines beyond vaccines. 4. British police said they would be taking no further action after conducting a review of evidence relating to sex crime allegations against Queen Elizabeth's son, Prince Andrew, and the late U.S. financier Jeffrey Epstein. 5. Beaches in a southern California city that were shut because of an oil spill last week are set to reopen, authorities said in a statement. #Alaska #Earthquake #UnitedStates #Taliban #Afghanistan #AstraZeneca #Covid19 #UnitedKingdom #BritishPolice #PrinceAndrew #Epstein #QueenElizabeth #Headlines #MorningNews #Business #News #Reuters Subscribe: http://smarturl.it/reuterssubscribe Reuters brings you the latest business, finance and breaking news video from around the globe.
