Detailed Description

What a frontend lends the source it opens and the screens it mounts.

Everything it lends (the runtime, the executor, the scheduler, the loop) outlives the screens and the connections made with it: a frontend destroys those, through runApp, before its runtime.

Member Function Documentation

runtime()

virtual reactive::Runtime & morph::ui::AppContext::runtime ( )

pure virtual

The runtime the screens are mounted in. Owned by the frontend.

Returns

The runtime.

executor()

virtual exec::IExecutor & morph::ui::AppContext::executor ( )

pure virtual

The runtime's owner, and the callback executor of every bridge handler the source and the screens make.

Returns

The executor; the same one as runtime().owner().

scheduler()

virtual Scheduler & morph::ui::AppContext::scheduler ( )

pure virtual

Timers that fire on the owner executor.

It honours every guarantee of reactive::Scheduler, as docs/spec/reactive/control.md ("The `Scheduler` contract") states them.

Returns

The scheduler.

ioLoop()

virtual exec::IoLoop * morph::ui::AppContext::ioLoop ( )

pure virtual

The I/O loop the frontend runs on, for sockets and timers that share its one thread.

Returns

The loop, or null when the frontend has none (Qt Quick).

quit()

virtual void morph::ui::AppContext::quit ( int exitCode = 0 )

pure virtual

Makes Frontend::run return once the current event has been handled.

Called before the loop runs (from AppSource::open, or from mounting the shell), it still ends the run once the loop starts.

Parameters

exitCode

What run returns.
