Question

Я пытаюсь реализовать привязку 'window.resizeTo' внутри cefsimple. Я использую 6-месячную iMa c, на которой работает Mojave 10.14.6.

Я успешно реализовал привязку окна, как описано в документах для Javascript Интеграция .

Я дошел до того, что мне просто нужно дать какао команду изменить размер окна. После вызова функции sed мое окно просто станет серым и замерзнет. (Обратите внимание, что приложение не заморожено, но само окно. Я предполагаю, что этот конкретный процесс рендеринга потерпел крах, в то время как процесс браузера все еще выполняется.)

Сейчас - мой код смоделирован после файлы window_test.mm и window_test_runner_ma c .mm и очень мало отличаются от них с точки зрения реального кода. Поиск в Google других примеров звонков по номеру [window setframe:...] не показывает очевидных причин, по которым мой звонок должен быть неудачным. В результате, я предполагаю, что не понимаю какой-то аспект синтаксиса.

Любая помощь будет высоко ценится. Ниже весь мой код. Файлы CMakeLists.txt и process_helper_ma c. cc стандартно поставляются с бинарным дистрибутивом, но модифицируются. Файлы window_controller.h,. cc и .mm созданы специально для моего проекта.

Заранее спасибо!
