The repostitory consists of 2 libraries.
sjis collection of primitives for launching async activities, this library doesn't have external dependencies except C++20 standard library,sj-qtcontains- class QScheduler -- Qt-specific implementation of
Schedulerinterface; - function
IProgress* create_progress_dialog(...)for creating progress dialog, interfaceIProgressextendsJobOwner.
- class QScheduler -- Qt-specific implementation of
sj-qt depends on sj and QtWidgets.
- CMakeLists.txt:
target_link_libraries(... sj-qt). - Somewhere in
int main(...):
QScheduler scheduler;
current_thread_scheduler::set(&scheduler);
- Usage of job and future:
void calc_in_background_and_update(IProgress* progress, MyWidget* view)
{
auto & job = co_await Job::GetCurrent;
auto future = job.async([...] {
return do_heavy_calculation();
});
auto result = co_await future;
view->update_ui(std::move(result));
progress->stop();
}
void MyWidget::calc_and_update()
{
auto progress = create_progress_dialog("Activity Name", this);
calc_in_background_and_update(progress, this);
progress->start();
}
