Widgets overview

[SimonHeybrock]

This is an overview of essentials to resolve for a first public version of the widgets:

Selected

• Implement BinEdgeWidget and improved BinEdgeParam #59.
• Implement optional parameters. [UI] Optional Parameter and Widget #71
• Implement [UI] Switchable Widget. #57.
• Improve Switchable Widget and handle intermediate parameters #74
• Show outputs using a vertical layout of checkboxes (instead of list, avoids need to use shift or ctrl ubttons)?
• Show extended outputs as combo-box, so they are mostly hidden by default
• Fix some UI logic around enabling/disabling buttons, make sure things can be run again, ...
• Implement mappable widget wrapping arbitrary other widgets, where rows can be added/removed, yielding a tuple of parameter values. Probably add a mappable field to class Parameter to enable this.
• Low hanging fruit for look&feel: Type formatting, description display, ...
• Split out workflow&output selection to its own widget, make it displayable in a tab (param settings should be in second tab).
• Helper functions to create widgets, instead of creating a single one in the module (some notebooks will need to create multiple workflow widgets). Helper functions to create widgets, instead of creating a single one in the module #68
• Parameter that can take existing Python object as input. The widget should parse the global namespace (maybe similar to https://github.com/scipp/scipp/edit/main/src/scipp/object_list.py?), providing a drop-down list of objects to select from. May be filtered by type.
• Save parameters widget input values and load them from a dictionary #140
• Add tests

Needs more thought

• How to select files on the server using a FilenameWidget?
• Consider Auto-generation of parameters #62.
