calling function from tool

[danilo2]

Hi! This is my tool function on the shelve (it reads rss and display links on the stage. When this function is pasted into hou.session module it works, but I want to make the same only from the tool. So everything works ok apart of opening browser with links.

The bottom commented line makes this error. How to fix it?

Thank you:)

# The webbrowser module is distributed with Python.  The feedloader module
# is part of this example and its code is listed below.
import webbrowser
import feedloader

use_help_browser = False

links = []

def openLink(index):
    """Open the URL for a given link index."""
    openURL(links[index][1])

def openURL(url):
    """Open a given URL in the browser."""
    if use_help_browser:
        # If a help browser is already open, use it.
        desktop = hou.ui.curDesktop()
        browser = desktop.paneTabOfType(hou.paneTabType.HelpBrowser)
        if browser is None:
            browser = desktop.createFloatingPane(hou.paneTabType.HelpBrowser)
        browser.setUrl(url)
    else:
        webbrowser.open_new(url)


def createObjects():
    """Load the RSS feed and create objects containing the titles.  When
       you click on the objects, they'll open the link in the browser.
    """
    # Load from an RSS feed into the links global variable, storing
    # (title, url) tuples.
    global links
    links = feedloader.loadLinks()

    # Delete all the existing objects in /obj.
    for child in hou.node("/obj").children():
        child.destroy()

    y_pos = 0
    for index in range(len(links)):
        text, url = links[index]

        geo = hou.node("/obj").createNode("geo", run_init_scripts=False)
        font = geo.createNode("font")
        font.parm("text").set(text)

        color = geo.createNode("color")
        color.setFirstInput(font)
        color.parmTuple("color").set((1, 1, 1))
        color.setDisplayFlag(True)

        geo.parm("ty").set(y_pos)
        y_pos -= 2

#HERE I WANT TO CALL THE OpenLink FUNCTION OF THIS TOOL, NOT HOU SESSION.

        #geo.parm("pickscript").set('python -c "hou.session.openLink(%d)"' % index)

    hou.node("/obj").layoutChildren()

createObjects()

You can't actually access and call code from inside a shelf tool except when the tool is running. To do what you want you would be best to put all your code inside a module and then call that whenever you need it.

Thank you

nut when I'm trying todo so:

geo.parm("pickscript").set('feedloader.goToLink()')

in the place I've orewiously showed, only error occured (after selecting the text) that Houdini doesn't see the feedloader (uknow command feedloader.goToLink).... hmm

How should i make it working?
