[PD]: Fix helix property visibility/writeability
* Hide irrelevant and internal helix properties
- The `HasBeenEdited` property is only used internally to check whether to
fill certain other parameters with initial values. So there is no need
show it in the property grid at all.
- The `Outside` property is only used in the subtractive helix and thus
hidden for the additive helix.
* Make derived helix properties read-only
Depending on the input mode, some properties are primary input, others
are derived. Prior to this change, also the derived properties have been
writable but their values are ignored and overwritten on the next
recompute. Now, when changing the input mode, only the primary input
props are writable.
* Reorder some helix properties
This change puts the reference axis and input mode at the top to become
more prominent. Only "Base" and "Axis" are higher in the list for
consistency with the other axis-based features.
Depending on the input mode, either `Growth` or `Angle` is used to create
a conical or flat spiral. The respective other can easily be calculated
to give consistent view. This is already done for the other properties,
e.g. `Height` is calculated from `Pitch` and `Turns`.
With this patch, the same is done for `Angle` and `Growth`.
Migrate to a UI that looks more like other software package managers, giving
more space to each addon by hiding the list when an addon is selected, and
providing a "back" button to get back.
Implements a two-style view option for the list of addons: expanded and
condensed, via a delegate that provides the drawing function for each row in
the table based on two different widget designs.
The pyrate has moved to salsa.debian.org, so this commit adds the
beginnings of support for those repos.The Markdown library is required
for nice rendering of repos that don't have a package.xml metadata file.
This shifts to use the model-view-controller pattern for the list of addons,
and moves to using a full model class rather than an indexed array for the
data storage and management. This enables much more information to be stored
as part of the new AddonManagerRepo data type. It now wraps the Macro class
for macros, supports Preference Packs, and provides access to the Metadata
object.
Rather than trying to use a generic Py::Object and assigning properties
to it, use a Py::Dict object for simple data structures like Url,
Maintainer, and Author.
Update metadata standard to include subdirectory
Constructing a string from a null pointer is undefined behavior: it
turned out to work with gcc and MSVC, but with XCode/clang it results in
a segmentation fault. Theis fix assumes that the expected behavior is to
yield an empty string.
