Node Custom UI

[Nicolas Lambert]

Hello everyone, 

First of all, thank you Andrea and all the contributors for this great openSource project!

I want to make a node with a custom UI, imagine adding a label with the state of the node, like in pipeline's demo, and a custom nodeInspector's behavior (add some buttons...)

Is it possible to make it in python or do I have to compile some classes??

Thank you

nico

Hello Nicolas.

You should look at the sound node.

https://code.google.com/p/coral-repo/source/browse/#git%2Fcoral%2Fexperiments%2FSoundNode

It seems to use custom QWidgets.

Good luck! :D

Dorian

Hi Niciolas,

To add custom widgets to the inspector you can refer to the link that Dorian highlighted, and there's also an example here:
http://code.google.com/p/coral-repo/source/browse/coral/examples/jitternNode/jitterNodePluginUi.py

Customizing the node-editor nodes is just as simple but less documented, have a look at this cluttered file:
http://code.google.com/p/coral-repo/source/browse/coral/coralUi/py/coralUi/builtinUis.py

Look for the registration point loadPluginUi and then look at

plugin.registerNodeUi("CollapsedNode", CollapsedNodeUi)

This is how coral pairs a NodeUi subclass to a node name, you should be able to figure things out from there.

Thank you, I'll take a look on. But for the jitterNode, I can't manage to run it... Perhaps I have to put it in a plugin folder?

Sorry for my newbies questions...

[Nicolas Lambert]

Do I have to add th ui class in builtinUis.py, or there is a way like in the jitter example to load an UI file?

It seems there is a way using plugin, but I don't find the way to correctly load plugin at the startup?

[Andrea Interguglielmi]

To load a plugin or a pluginUi from a running coral instance fire this in the script editor:

from coral.coralUi import coralUi
coralUi.loadPluginUi("myPluginUi.py")

from coral import coralApp
coralApp.loadPlugin("myPlugin.py")

[Nicolas Lambert]

Ok thank you!

Just to know, if I want to have my nodes loading at the startup, I have to implement them directly in the core, or there is a folder scanned a the startup?

[Andrea Interguglielmi]

You can set this environment var before to launch coral:

CORAL_PLUGINS_PATH = "/myCoralPlugins"

[Nicolas Lambert]

Great!!

Thank you for your reactivity, and enjoy Dreamworks!! 

[Andrea Interguglielmi]

And there's also this other env you can set:

CORAL_STARTUP_SCRIPT = "/blah.py"

That lets you do whatever you need to customize coral at startup, you can load plugins, customize menus, whatever.
