python OPmenu issue

[krishna]

Hi Guys,

First post since I joined odforce.

I am trying to make a tool which could create filecache node on the right click of a null node.
The moment I hover my cursor on the "mdu" option, before clicking it's creating filecache node.

Its a submenu option, so I think I am missing some thing important.

<?xml version="1.0" encoding="UTF-8"?>

<menuDocument>
    <menu>
    <subMenu>
        <label>mdu</label>
        <actionItem id = "create.rop.node">
        <labelExpression><![CDATA[
node = kwargs['node']        
result = 'Create Rop Node'
sel = hou.selectedNodes()[0]
if sel.type().name() == 'null':
    selName = sel.name().split("_")
    joinName = "_".join(selName)
    nodeName = joinName.replace('OUT_',"")
    
    if selName[0] == 'OUT':
        nodePath = sel.path()
        node = hou.node(nodePath)
        node.createOutputNode("filecache",nodeName)
    else:
        raise hou.Error("Invalid Node name")
else:
    print sel.name() + " is not valid for cache"
    result = u"\u2713 " + result
return result
        ]]></labelExpression>
        <context>
            <expression>kwargs["node"].type().category().name() in ("Sop")</expression>
        </context>
        </actionItem>
    </subMenu>
    </menu>
</menuDocument>

 

Thanks

labelExpression should be used when you want to dynamically show/hide menu items, main script should go under scriptCode or scriptPath tags
