How to find the name of the node_group from a Node? about sverchok

[zeffii]

print(bpy.context.space_data.node_tree.name) works, so will use that.

[ly29]

node.id_data.name

[zeffii]

maybe my eyes deceived me, but I thought that was returning the node name as opposed to the tree name. weird.

[ly29]

>>> D.node_groups['MyNodeTree'].nodes['Viewer Draw.003'].id_data.name
'MyNodeTree'

great!

I think best way to do the larger task you mention is to have a something like a layer manager in the right toolbar.

so in the class SverchokToolsMenu(bpy.types.Panel): node_Tool.py

        for i,name in enumerate(bpy.node_groups.keys()):
            row=layout.row()
            row.layout(text=name)
            row.prop(bpy.node_groups[name], "animate", text="Animate?")  

And we add the bool property in node_s.

And furthermore we can make update_ani function that updates the tree without rebuilding like update does since that is for editor changes.

[ly29]

In fact I will to that this right now.

[zeffii]

yes, this makes sense! I was going a different route, but not as sophisticated as your approach.

[ly29]

It also strikes me that we could have option to show the many node groups or not. instead of animate.
@nortikin Any comments?

        layout.label(text="Animation layers")
        ng = bpy.data.node_groups
        for name in ng.keys():
            if ng[name].bl_idname == 'SverchCustomTreeType':
                row=layout.row()
                row.label(text=name)
                row.prop(ng[name], 'sv_animate', text="Animate?")

The snippet would become something like.

def my_handler(scene):
    for name,tree in bpy.data.node_groups.items():
        if tree.bl_idname =='SverchCustomTreeType':
            tree.update_ani()

bpy.app.handlers.frame_change_pre.append(my_handler)

where update_ani() works like

 def update_ani(self):
        if self.sv_animate:
            speedUpdate(tree_name = self.name)

The layout needs to be adjusted.

[ly29]

Something more like this seems better.

[ly29]

        box=layout.box()
        box.label(text="Layers")
        ng = bpy.data.node_groups
        col=box.column(align=True)
        row=col.row(align=True)
        row.label(text='Name')
        row.label(text='Show')
        row.label(text='Animate')
        for name in ng.keys():
            if ng[name].bl_idname == 'SverchCustomTreeType':
                row=col.row(align=True)
                row.label(text=name)
                row.prop(ng[name], 'sv_animate',text=' ')
                row.prop(ng[name], 'sv_animate',text=' ')

Note that right now animate and show are the same option, that would obviously have to be changed.

[ly29]

Of course ViewerDraw and other nodes that draw or bake would have to be updated also. And a bake options perhaps would be good also. Things get more complex so easily. I will stop now waiting for comments.

[nortikin]

previusly i supposed the it will be only button, but now it looks more "professional" or something like that.
It suits me, cool approach to handle animation update with boolean.
Lets call it layouts, because layers - is something different

Do you mean, that viewer draw and bakery should be hided if not flag on?
Somehow i binded viewer draw to tree name and node name, but from 3d view data disappear if you change layout and if in new layout there is node with the same name.
