Switch Radio Button in Python


Recommended Posts

Hi Szalbolcs, I am python newbie, so there is probably better solution. I wanted to switch Tabs (which is just different type of folder, Radio Buttons are also type of folder) with python. I solved it like this:

- add new int parm (invisible)
- add expression, reference the name of the first Tab (add "1" to the name)
- switch that new int parm
- Tabs get synced, as "side effect"

Maybe you will find a better solution. Otherwise, here is mine. Attached is .py doing all these steps.


EDIT: btw for some reason, the initial naming of Tabs (when the node is created) is "wrong" and gets updated as soon as you read (or update) the UI. So, in my code, I start by addSpareParmTuple() and then ask for the Tab name. This is some Houdini thing, which I don't understand. You may try to read parmTemplateGroup() entries() on a new node twice. The second time, folder names are different, updated. Then they stay like this.

Thanks,  it can NOT work for me but unfortunately I can not modify the parameters now.

That's not mine. But i don't think ther is no other way to switch between radio buttons.  Any other idea?

you just need to know the name of the first radio button folder

then for some reason append 1 to its name to be able to access it 

so if your folder is called 'folder', then you access it as yournode.parm('folder1')

if the name is 'folder1' , then you access it as yournode.parm('folder11')

that being said, to switch the radio button you just set the value on such parm, , then you switch it as yournode.parm('folder1').set(2)

to try this out place Fuse SOP (let's say it's in '/obj/geo1/fuse1')

fuse = hou.node('/obj/geo1/fuse1')
