Simplify the FilterComboBox to rely on the default behavior
provided by the ComboBox control.
Improve the filtering system and the ability to set a custom value.
Turn to a more declarative approach with regard to handling
value update and its mapping to the combobox's current index.
Ensure attribute input connection is serialized, even for List/GroupAttributes.
Note: while connecting GroupAttributes is not yet supported, this will benefit
this type of attribute once it is.
* Deserialization: Replace the logic that defaulted the node type version to "0.0" when unspecified,
and assume that unspecified version on a node is targetting current node type version.
* Serialization: Only serialize node type versions for which a version info is available.
* Test suites:
* Add helper context manager to manually override the version of a given node type.
* Add new unit tests to cover version conflicts handling is various scenarios.
At the end of the deserialization process, solve node uid conflicts iteratively by node depths,
and only replace the conflicting nodes with a CompatibilityNode.
Add new test suite for testing uid conflict handling.
Add a new method to create a copy of a graph instance, relying on
chaining serialization and deserialization operations.
Add test suite to validate its behavior, and the underlying serialization processes.
Re-implement node pasting by relying on the graph partial serializer,
to serialize only the subset of selected nodes.
On pasting, use standard graph deserialization and import the content
of the serialized graph in the active graph instance.
Simplify the positioning of pasted nodes to only consider mouse position
or center of the graph, which works well for the major variety of use-cases.
Compute the offset to apply to imported nodes by using the de-serialized
graph content's bounding box.
Only perform uid check when we have both a serialized and a computed
UID.
If the node has not been serialized with a UID, it means that it does not
expect to match a specific value on deserialization.
Add a new serializer class to manage partial graph serialization logic,
ensuring to remove link expressions on attributes refering to nodes
that are not in the subset of nodes to serialize.
Move the serialization logic to dedicated serializer classes.
Implement both `GraphSerializer` and `TemplateGraphSerializer`
to cover for the existing serialization use-cases.
Move Graph.IO internal class to its own module, and rename it to `GraphIO`.
This avoid nested classes within the core Graph class, and starts decoupling
the management of graph's IO from the logic of the graph itself.
When creating a compatibility description for an unknown attribute, do not
consider a link expression as the default value for a File attribute.
This is breaking how the link expression solving system works, as it's resetting
the attribute to its default value after applying the link.
If that expression is kept as the default value, it can be re-evaluated several
times incorrectly.
Added a test case that was failing before that change to illustrate the issue.
Extract the logic of importing the content of a graph within a graph instance from
the graph loading logic.
Add `Graph.importGraphContent` and `Graph.importGraphContentFromFile`
methods.
Use the deserialization API to load the content in another temporary graph instance,
to handle the renaming of nodes using the Graph API, rather than manipulating
entries in a raw dictionnary.
* API
Instead of having a single `load` function that exposes in its API
some elements only applicable to initializing a graph from a templates,
split it into 2 distinct functions: `load` and `initFromTemplate`.
Apply those changes to users of the API (UI, CLI), and simplify Graph
wrapper classes to better align with those concepts.
* Deserialization
Reduce the cognitive complexity of the deserizalization process
by splitting it into more atomic functions, while maintaining the
current behavior.
Connecting the valueChanged signal to a lambda causes performance
issues with a large number of attributes when using the Pyside backend.
Connecting that signal to an intermediate Slot part of the Attribute class
improves performance dramatically.
Note: This has no comparable impact on the standalone backend.
With Qt6 the geometryChanged method was updated to be called as geometryChange and with that update QQuickItem was not getting internal updateShape to get invoked upon updates
In some cases, like when opening the most recent file from the command
line, switching the color palette or hot reloading, the intrinsics
might be parsed and ready to populate the intrinsics' `TableModel` while
the model itself is being instantiated.
To prevent crashes, we forbid operations on the `TableModel` until it has
been fully instantiated.
