- pkgc -> packageChoice and similar for methods, variables
- document that this is the convenience value for one-selection
QML modules, not a full model
- use std::optional to keep track of which one is being used.
function added to store selections from packagechooserq
line 103 in Config.cpp needs adjusting to restore working regular widget based packagechooser
prettyStatus added, made visible in packagechooserq only, ViewStep not altered in packagechooser for this yet
- in legacy mode, *id* can have an effect and leads to
"packagechooser_<id>"; if unset, uses the the module
instance id instead, still as "packagechooser_<instanceid>".
- in packages mode, *id* is not used and only the whole
module Id (generally, "packagechooser@<instanceid>")
is used, but in packages mode there's no need for other
packages to mess with GS settings for this packagechooser.
When the module is loaded and the viewstep created, it doesn't have a
module Id **yet**. That is set after reading more of the configuration
file. It **is** set by the time setConfigurationMap() is called,
so pass it on to the Config object then. This means that packagechooser
modules can skip the *id* config key and use the module Id.
The model needs to be attached to the widget; because of changes
in the order that widget() and setConfigurationMap() are called,
the model is created earlier, but needs to be connected later.
- don't pass the item IDs to packages module, use the
packages lists for each item
- document the item list in more detail (including the packages member
and new install-method item)
Rip out most of the ViewStep that deals with configuration,
move it to a Config object (not one that supports QML yet,
though), and massage the model a little.
