Re-write the computability status of the current node selection
as properties within the node menu component.
Note that this should be further improved to better scale with the size
of the selection, as it requires to traverse the graph for each node.
Avoid having the node context menu always evaluating the current
state of the selected nodes for its own display, by dynamically
creating it on demand with a Loader.
Use callbacks for recomputing/resubmitting actions, instead of
storing state in the UI components.
Switch selection management backend to a QItemSelectionModel,
while keeping the current 'selectedNodes' API for now.
Use DelegateSectionBox for node selection in the graph, and
rewrite the handling of node selection / displacement.
Fixed the issue where navigation arrows on the Filtering was allowing to set an index even when the search had null as the result.
Accepted signal on the Seach invokes the function rather than invoking the sigal for the button
If unexposed attributes (ie. attributes that are located in the lower
side of a node, and hidden by default) are connected, they are meant
to remain visible even if the lower part of that node is hidden.
This was working fine for any attribute that was not a `ListAttribute`,
as the check was made on whether the attribute's value was a link to
another attribute. For `ListAttributes`, whose value is actually a list
of values, this was not working as nested links were not checked.
Instead of relying on the `isLink` property, we now use `isLinkNested`:
for regular attributes, this is equivalent to using `isLink`, but for
`ListAttributes`, the full list of values will be checked.
The color selector in the Graph Editor provides a quick way to color nodes with predefined palette of colors.
Added Command to allow the Coloring to be undone and redone using QUndoStack
The callbacks of `childrenRepeater` (which was used to "fill"
`ListAttributes` with children) were not correctly set. Their prototypes
were missing the `index` argument, meaning that instead of being
provided with the child attribute that was added or deleted,
they were provided with its index in the model.
The added children attributes were also instatiated as empty attribute
pins that were still visible, thus increasing indirectly the spacing of
the initial pin.
The curve scale of the mouse area for an edge used to be defined when
initializing the `EdgeMouseArea` for that edge. Setting it triggers a
chain of event that allow the mouse area to be active, thus correctly
detecting when it is being hovered or clicked on.
With Qt6, these events unfolded before the `EdgeMouseArea` had finished
initializing, which then caused it to not be active until the edge's
shape was modified (and the chain of events triggered again). It is now
set once the component has been created, so all the events can happen
in an environment where they are taken into account.
Editing the pins manually was useful when trying to hide fully the
connection whenever there was an edge connected to an attribute that
was disabled. Disabled attributes now have a special display if they are
connected, meaning both ends of the edge do not need artificial updates.
