Python - Multi selections for selectNode

[salik]

Hi all, I have just started trying to use Houdini api docs to do some scripting and was met with some issues.

So, I am trying to call a ui/command where the user will be presented with a certain hierarchy and is to perform multi selections of an operator type (let's call it `customRefs`). Currently I am only able to find a command namely `hou.ui.selectNode(relative_to_node=“/obj/StackLvl”)`, however it presents me the whole hierarchy as what you would see in a typical Tree View and it only allows a single selection.

Was wondering if anyone knows of any other commands that I can do multi-selections since I will need to grab the name of the selections made by user?

A simple example of how the hierarchy would be:

/obj/StackLvl
 |- /obj/StackLvl/char
 |- /obj/StackLvl/acc
     |- /obj/StackLvl/acc/item01
     |- /obj/StackLvl/acc/item02
 |- /obj/StackLvl/takes
     |- /obj/StackLvl/takes/cut01

 

All of them are of custom operator types.
customRoot = ‘StackLvl’
customGroup = ‘char’, ‘acc’, ‘takes’
customRefs = ‘item01’, ‘item02’, ‘cut01’

There is node_type_filter parameter accepting one of hou.nodeTypeFilter values.

hou.ui.selectNode(node_type_filter=hou.nodeTypeFilter.Sop)

Yes, but unfortunately this still only allows and return 1 selection.

I managed to get it over by using `selectFromTree` command instead in which I grab the path of all its child nodes of a certain hierarchy level which prompts a window populate. And it is able to present them in a tree view, the same as as in a typical tree view!

Just a side question though, is it any way possible to add in additional buttons to these hou.ui window popups?
For example, I would like to add a 'HELP' button that points to a web page..
