* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
Adds a new, cleaned up, HashMap implementation.
* Uses Robin Hood Hashing (https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing).
* Keeps elements in a double linked list for simpler, ordered, iteration.
* Allows keeping iterators for later use in removal (Unlike Map<>, it does not do much
for performance vs keeping the key, but helps replace old code).
* Uses a more modern C++ iterator API, deprecates the old one.
* Supports custom allocator (in case there is a wish to use a paged one).
This class aims to unify all the associative template usage and replace it by this one:
* Map<> (whereas key order does not matter, which is 99% of cases)
* HashMap<>
* OrderedHashMap<>
* OAHashMap<>
This commit adds two signals:
* connection_drag_begun, which is emitted when a connection is started
to be created by the user and
* `connection_drag_ended`, which is emitted when no longer a connection
is created.
Additionally `force_connection_drag_end()` adds the possibility to end
the connection dragging. If called from user code, no other connection
request signals are invoked. This is useful to add `GraphNode`s via
shortcuts while the user is dragging a connection to directly connect
the newly added node.
* `_gui_input`, `_input`, `_unhandled_input` and `_unhandled_key_input` are now regular C++ virutal functions.
* Everything else converted to GDVIRTUAL
* BIND_VMETHOD is gone, always use the new syntax from now on.
Creating `_gui_input` method and using the binder to register events will no longer work, simply override the virtual function now.
Remove duplicate bezier code and use Curve instead.
Add an overridable method for retrieving the points of a connection line, which
makes it posible to create custom connections lines.
This PR and commit adds the functionality to arrange nodes in VisualScript/VisualShader editor. The layout generated by this
feature is compact, with minimum crossings between connections
& uniform horizontal & vertical gaps between the nodes.
This work has been sponsored by GSoC '21.
Full list of additions/changes:
• Added arrange_nodes() method in GraphEdit module.
• This method computes new positions for all the selected
nodes by forming blocks and compressing them.
The nodes are moved to these new positions.
• Adding this method to GraphEdit makes it available for
use in VisualScript/VisualShaders editors and its other
subclasses.
• Button with an icon has been added to call arrange_nodes() in GraphEdit.
• This button is inherited by VisualScript/VisualShaders editors
to invoke the method.
• Undo/redo is functional with this method.
• By using signals in arrange_nodes(), position changes are registered
in undo/redo stack of the subclass that is using the method.
• Metadata of the method has been updated in ClassDB
• Method description has been added to class reference of GraphEdit
