I am attempting to create a modal menu that updates it's contents based on the currently highlighted primitive in a viewer state.

The data on the node is a multiparm string menu of options, where each instance of the multiparm is driven by script. So each prim contains different options in the menu script;

prim0 = “OptionA”, “OptionB”
prim1 = “OptionA”
prim2 = “OptionC”, “MyOtherOption”


Is it possible to build a menu in a viewer state dynamically?

I have looked into onMenuPreOpen(), which gives me the access to setting parms on an existing menu, but I cannot seem to build/update an existing one with addRadioStripItem() as I can't grab the menu object.


Any thoughts? Any other approaches to look at? Could I bind a menu parm instead?

Cheers,
Aaron.

Dynamic menus are not supported at the moment, there is an RFE logged for that.

OK great to hear, looking forward to it.

I am going to use the mouse-wheel and a hou.Drawable() to show the text for now.

Cheers.

You can also fake a dynamic menu by updating the menu item label and visible states. I'm backporting a fix for that to H18.0, it should be available in the daily builds tomorrow.

Hi mabelzile,

I was looking for something similar, could you explain how to implement this ?

I was also thinking that maybe I could implement a hou.parmTemplateType.String. When I right click on it I get “No Options Available”. Is there a way to dynamically populate Options for this ?

Thanks a lot in advance,

Julien

You can update the python state context menu with onMenuPreOpen which is called before the menu opens up when you RMB. For instance, you could create your context menu with all possible menu items you want to support. Then in onMenuPreOpen you can decide which menu items you want visible or change labels, etc… (see attached example)


State dynamic parameter menu is not yet supported.
