    To avoid confusion, the PB include file should have used TVINSERTSTRUCT,
    not TV_INSERTSTRUCT to follow current naming conventions as per MicroSofts
    updates.

    > is there any advantage to this alternate structure.

    Well, one advantage is that Dave's code will compile.

    Seriously, the TVITEMEX structure adds the lIntegral element, which can be used to create oversized items for owner-drawn treeview items. If you don't need that feature, there's no real advantage.

    But IMO it's best to use the lastest WIN32API.INC files as improvements are made by PowerBASIC Support, regardless of whether or not you need the specific improvements. One of these days they will change something you do need, and then you would have to choose between "catching up" with all of the changes, or forever cutting and pasting custom versions of WIN32API.INC for your own use. Been there, done that, learned my lesson...

    P.S For more info about lIntegral....

    Jules --

    I suspect that you're not using the latest COMMCTRL.INC file. I checked the file that is (internally) dated December 10, 1999 and it does contain the structures I posted.

    The latest files are available for download from this web site.

    No, "Item.Item." is correct. The structures are nested this way:

    Code:
    UNION TV_ITEM_UNION
        itemex AS TVITEMEX
        item AS TV_ITEM
    END UNION
     
    TYPE TV_INSERTSTRUCT
      hParent AS DWORD
      hInsertAfter AS DWORD
      item AS TV_ITEM_UNION
    END TYPE
    So if you DIM a structure as a TV_INSERTSTRUCT it has an element called Item that is a TV_ITEM__UNION, which has an element called Item.

    Not ideal naming, perhaps, but the compilers have no problem keeping it straight.

    Yeah, I thought that was weird too. Doesn't compile if you remove
    the second .Item though [or the first .Item ;-)].

    Hey guys!

    I was playing around with this code today...

    In the TVInsertItemBMP function you need to change

    tv_insert.Item.Item.mask = %TVIF_STATE OR %TVIF_TEXT OR %TVIF_IMAGE

    to

    tv_insert.Item.Item.mask = %TVIF_STATE OR %TVIF_TEXT OR %TVIF_IMAGE OR %TVIF_SELECTEDIMAGE

    otherwise the selected image is always going to be the oFolder bitmap
    for the children. Weird.

    Thanks to Eric Pearson who gave me some pointers... I got it working (sort of).

    I can't control (yet) which image is displayed for each "state" of a branch (open/close).

    You can download the code, bitmaps & sample from http://www.basicguru.com/navarro/tview.zip

    started a topic Treeview

    Treeview

    I downloaded the source for adding a TreeView control to DDT.

    Does anyone have an example for adding icons to the Treeview?
