Clicking restore-defaults on an Experiment or Instrument tab in a batch should only affect that tab and batch. This commit fixes a bug where a notification was sent to all batches, and every Experiment and Instrument tab was being reset. The fix is to separate updating the instrument (which is required to ensure we have up-to-date settings loaded from the instrument) from the subsequent notification which updates all batches. Instead, the particular Experiment/Instrument tab where the request was made restores its own defaults itself.

Re #28429

Tidy up existing tests to improve readability

Re #28429

Also updated class_maker.py

This commit replaces all header guards in qt/scientific_interfaces with #pragma once.

Add a separate method for opening the save/load dialog. Previously it
was always opening the save dialog to get the filename.

Re #27242

These are now injected into the main window presenter's constructor so
that they can be tested.

Re #27242

- Move the QFileDialog implementation into the view so that the
presenter does not need to know about it. Call the dialog functions via
the IMessageHandler interface.
- Move the save/load JSON functions into the view. Call them via a new
IFileHandler interface. Note that not all Qt types are removed from the
view's interface yet so a TODO has been added.

Re #27242

re #27319

The reflectometry GUI sets the default instrument in the config service
when it starts up to one of the ISIS reflectometers. This commit adds a
check that the facility is ISIS and if not it sets the facility to ISIS.
This avoids confusion where you essentially have invalid config. It also
avoids confusion where e.g. loading runs from the default archive might
not work because the archive may be a different facility.

I have also added code to save the new config settings to file. Again
this is to avoid confusion between what users see in mantid and what is
in the saved settings. It is particularly confusing otherwise because
Workbench will write settings to file when it closes but MantidPlot will not.

Re #27241

An argument was missing from a refactored function

Re #26533

Also includes some minor refactoring of tests which require an
instrument to be set to construct the instrument directly in the test
rather than call a notification function which causes the instrument to
be loaded from the name.

Re #26533

Coordinate via the main window to disable the instrument drop-down box
on all Batch tabs if any batch is processing or autoprocessing.

Re #26536

Make these clearer that they are notify functions

Re #26536

Re #26536

Use clearer names to indicate a notification of a request, a function that performs the action, and a notification
of a result from that action.

Re #26536

Re #26536

This is no longer necessary now that the instrument is stored in and set
by the main window

Re #26536

Setting initial state is done by the main window after adding a new
batch is complete and all presenters know their parent presenter. Move
the initialisation of the instrument list to the same place.

Re #26536

The instrument has been moved to the main window so that it can be
synchronised between batches

Re #26536

Update invalid include path. Add missing updates to new files (new
include file and new namespace).

Re #26498

Add an interface to the BatchPresenterFactory.
