Listbox with Explorer capabilities, well some of them.

[Anonymous]

All,

I was wondering what it might take to build a cascading list into a listbox. This may already exist, but I haven't seen
it in AutoLISP/DCL.

I would like to group selections by hierarchy, their position in the list. I was thinking that simple indenting might
work, with examination of the white space (or other char) in the prefix of the list name. This would let me access
storage level of each item in the list.

Something like this

Group1
Major1
Minor1
Minor2
Minor3
Major2
Minor1
Minor2
Minor3
Major3
Minor1
Minor2
Minor3
Group2
Major1
Minor1
Minor2
Minor3
Major2
Minor1
Minor2
Minor3
Major3
Minor1
Minor2
Minor3

Where each item picked would also select all subentities as well.

Anyone got something like this, or ideas about the foolhardiness of trying this with strictly AutoLISP and DCL :c)

Thanks

Hi this can be done using ObjectDCL. It is called a tree control and it is the exact control that is used by the explorer. You can find it at www.objectdcl.com Thanks Chad Wanless

I think I had problems using tabs in a listbox. They're not recognized or
too long or something. Besides the text style in list boxes is formatted so
the indentations wouldn't look good.
