There is nuke.CascadingEnumeration_Knob which gives you a an enumeration list with checkboxes, but I'm not sure how to make it accept multiple selection. Probably some kind of flag that needs to be set.

Howard,

Yes, I'm doing something similar with the view names. I filter a list in various ways and populate a pull down, which can be used to further filter the list, etc. The piece I'm missing is the multi-selection pulldown at the end. I would love to see how you've done it! I'm using Python_Panel and I just can't figure out how to make the multi-selection pulldown from the list of built-in knob types...

Thanks!

How are you intending to filter?

I built a script a while ago that gives you a drop down, this then is used to filter the next stage which is a list of episodes with check boxes, with multi selection allowed, this then creates a panel populated with the shots found from the selected episodes. This way I could select a project/episode/and shots and add data to the shots (such as approved etc).

Would something like that be suitable

All done with the simple panel

    *Subject:* [Nuke-python] Pulldown_Knob with multiple checkboxes…?

    Hi all,

    I am hoping someone might have a solution for this…
    (cross-posting again)

    I'm trying to create a pulldown menu that has the ability to
    check multiple boxes. Basically, I am trying to put the
    functionality of the special nuke.MultiView_Knob into a regular
    pulldown menu… Why, you ask?  Because I want to *filter the list
    of views*, since right now it bleeds off my second monitor and
    into thin air…

    I can create a new MultiView_Knob in my own Python_Panel, but
    since it's a private menu type, I can't do anything with the list
    of views it holds. I've tried and it always gives me,
    essentially, nuke.views()...

    The Enumeration_Knob only allows one selected item at a time -
    same with the Pulldown_Knob. So, short of building my own panel
    with PySide or PyQt - which I have not gotten into, yet - is
    there any type of pulldown that would allow each item to have its
    own on/off checkbox - a multi-checkbox pulldown menu, if you will?

    I hope that's somewhat clear what I'm looking for!  (8^\

    Thanks for any help,

    Rich
