open_file() [1/2]

MAYAFLUX_API void MayaFlux::Portal::System::Dialog::open_file	(	ChooserCallback	callback,
		std::vector< ChooserFilter >	filters = {},
		std::filesystem::path	start_dir = {}
	)

Present a native open-file dialog, delivering the result via callback.

Primitive overload. The callback receives a ChooserResult and is responsible for checking and unwrapping it. Invoked exactly once on the platform backend thread; callers that need thread affinity must marshal the result themselves.

Parameters

callback	Invoked with the chosen path or a SystemDialogError.
filters	Extension filter groups shown in the dialog.
start_dir	Directory the dialog opens in. Platform default if empty.
