A unified and configurable Nodegraph wrapper for Visual Effects Applications

coconodz's Issues

undisplay coconode in nodegraph

highlight connection when hovering over

attribute context gets only filled after second click

When opening the attribute context it should be filled with the existing node attribute immeditately.

pause all events on maya scene load, plugin load and new scene

configurable connection line mode

Qt supports different "line type" for QPainterPaths. Nodz uses a cubic bezier curve, but we should also support simple "direct" lines.

nodegraph glitches

We are noticing some glitches we're the graphicitems will not get updated properly. We have to investigate why.

node comments

Having node overlays #29 would allow us to add node comments. We could add a simply bubble icon which would open a separat dialog for adding a node comment.

implement backdrop widget

We would need the possibility to add Nuke-like backdrops within the nodegraph.

backdrop context is not showing color on QToolButtons

configurable nodetypes per application

Currently we are using hardcoded nodetypes. It would be easy to add the nodetypes to the configuration.

Moving items outside the canvas seems not to update the canvas size

create attribute on host connection

Currently we are only connecting coconodes if the attribute already exist on that node. We should automatically create the attribute on the coconode when a host connection was made and create the connection.

proper save and load graph functionality

We would need a new implementation to store the nodegraphs current nodes and backdrops.

add pause_events method to events class

We will need the possibility to pause specific events, for example when closing the nodegraph we don't want to trigger or listen to any signals.

shading engine template hook still active after event was removed

node overlays

We should be able to provide node overlays that can simply use an svg file, render and overlay it on the node.

focus issues

There are several focus issues within the Nodz implementation. We have to fix them.

implement moveable canvas

We should add

Alt + MMB to move the canvas

Nodzgraph not updating in Maya when window is docked

only preserve selection when using shift + LMB

reload modules and reinitialize graph

We should add the possibility to reload all python modules and reinitialize the current graph.
Currently we would need

• a reload function that reloads all coconodz modules
• a debug menu entry with reload action
• a nodegraph reinitialize function that removes all events and registers them again after, stores the current graph, closes and reopens it

handle doubled signal emission

Currently we are running into the situation when connecting a coconodes that we are emitting a signal to connect the host nodes, but in the host we are also emitting a signal to connect the coconodz nodes through a connected callback.This will lead to recursion or in case of Maya to a doubled signal

improve connection widget selection handling

At the moment it is quite hard to move the cursor to the right spot when doing nodes disconnections.
We have to improve the default selection behaviour and match it to the baviour in the Maya nodegraph.

layout nodes

node creation at creation field position

Currently when a coconode gets created it will be positioned within the nodegraph center.
We have to place it to the position the creation field was invoked from.

find a way to use right click for multiple context widgets

We only want to use the right click command to open a context widget dependent where it gets invoked from.

register coconodz as maya plugin

Coconodz should be a Maya plugin. Loading the plugin will create the menu and register all events, unloading will deregister all events and remove the menu.

implement dot nodes

When using linear connection lines we will need dot nodes.

add existing host node to nodegraph

plausible positioning when adding connected nodes in nodegraph

implement metadata widget

To inspect metadata it is common to have a semi-transparent widget that shows all the available metadata.
We could consider to use tooltips for that and require metadata as html.

backdrop sorting feature

emit signal when "Open Nodegraph" button gets clicked

With our shading engine template hook we are adding an "Open Nodegraph" button. We have to emit a signal when the button gets clicked to open the Nodegraph and allow to add additional functionality.

add on_node_selected callback

Maya interfering Tab Key when window is docked

We have to get the TAB hotkey ownership back!!
This could be a potential workaround

GraphContext should have the option to be a Hotbox

Hotbox widgets like we have it within the Maya nodegraph are nice and probably better then simple "list" widgets. We should implement a hotbox widget and consider this as the GraphContext widget.
