Help in creating a custom button, plez

Help & Support
1

Alright, this one has got me confused. I've searched the help file for Opus 11.18, but I just get lost in a trail of information. What I'd like to do is create a button that will delete any directories in the active lister that have a size of less than 100 KB, with a confirmation dialog just prior to doing the actual deletion. At times, this might total 4 directories, at other times, there might not be any at all. So, I come with hat in hand, and ask for help. I would consider this an education by way of spoon-feeding. :smiley:

Many thanks for any enlightenment!

No thoughts, Leo?

I am putting forth my best effort on this one, but my best isn't cutting it.

The workflow of the button should go something like this: SelectAll, GetSizes, Select Size= [ (less than 100KB) This is where I get stuck ], Delete Selected .

So, I have made a test folder with 2 folders in it, one empty and one with a large file. I then created a new button, and entered the above commands in the Advanced section. The SelectAll works fine, the GetSizes works fine, but I get stuck on the section where I want it to select folders with <100 KB. Nothing I do seems to work.

I have dropped the idea of a confirmation dialog, for the time being, just so I can try to get the basic button up and running.

I would very much appreciate any help on this.

Alright, I've found that I was trying to make things too difficult. I now have the button working with the following

GetSizes
Select Size <100kb
Delete

Fine and well. At this point I still seek help with adding a confirmation dialog box to the buttons' code, informing me of what folders will be deleted, and asking for permission to proceed.

Any pointers on that?

The SelectEx-ScriptAddin should be able to select folders within a size range:

SelectEx FOLDERS LINEAR MAXSIZE=100kb ITEMCOUNTPERC=100 MAKEVISIBLE DESELECTNOMATCH

Find it here: [Command: SelectEx (extended Select command))

Thanks, tbone! I'll look into it, and see if it works for me.

Appreciate the input.

And the Confirm-ScriptAddin should give you a proper confirmation dialog, listing affected items:

Confirm MSG="Really delete {#selitems$} items?\n" TITLE="Delete Folders" ITEMS={allfile$}

Combined:

Select NONE
SelectEx FOLDERS LINEAR MAXSIZE=100kb ITEMCOUNTPERC=100 MAKEVISIBLE DESELECTNOMATCH
Confirm MSG="Really delete {#selitems$} item(s)?\n" TITLE="Delete Folders" ITEMS={allfile$}
Delete QUIET

The "Select NONE" at the top is required because of some specific DO magic.
The Confirm Script-Addin can be found here (still missing some more detailed description):

Et voilà o):

EDIT: Url to script addin updated (german DO forum was closed / reopened).

Outstanding, I believe that will do the trick!! Now, I just have to learn how to apply the scripts and such, and when I've done that, I'll post back with my results. Very kind of you to help!!
