TreeGadget Flags

Still waiting for a native PB flag that forces all branches of a TreeGadget to be open/displayed.

Ruff translation of my C code that does what you need.

As I only have the demo, so you can tell me how close I wasn't

;-----------------------------------------------------------------------------
; Expand TreeView
;-----------------------------------------------------------------------------
Procedure TreeViewExpandAll(gadget.l)
    hwndTV.l = GadgetID(gadget)  
    hRoot.l = SendMessage_(hwndTV, #TVM_GETNEXTITEM, #TVGN_ROOT, 0)  
    hItem.l = hRoot  
    Repeat
        SendMessage_(hwndTV, #TVM_EXPAND, #TVE_EXPAND, hItem)
        hItem = SendMessage_(hwndTV, #TVM_GETNEXTITEM, #TVGN_NEXTVISIBLE , hItem)  
    Until hItem = #NULL  
    SendMessage_(hwndTV, #TVM_ENSUREVISIBLE, 0, hRoot)
EndProcedure
;-----------------------------------------------------------------------------
; Collapse TreeView
;-----------------------------------------------------------------------------
Procedure TreeViewCollapseAll(gadget.l)
    hwndTV.l = GadgetID(gadget)  
    hRoot.l = SendMessage_(hwndTV, #TVM_GETNEXTITEM, #TVGN_ROOT, 0)  
    hItem.l = hRoot  
    Repeat
        SendMessage_(hwndTV, #TVM_EXPAND, #TVE_COLLAPSE, hItem)
        hItem = SendMessage_(hwndTV, #TVM_GETNEXTITEM, #TVGN_NEXTVISIBLE , hItem)  
    Until hItem = #NULL  
    SendMessage_(hwndTV, #TVM_ENSUREVISIBLE, 0, hRoot)
EndProcedure

I guess I should have used Bold on my message...

I asked for a "native PB flag", not a workaround.

How can your app be cross platform if you fill it full of Windows API calls? Right now one must loop through using SetGadgetState as a workaround to keep everything cross platform but that way is very slow ;(

Hmm, TreeGadget is a "Windows only" Gadget. It's not supported on
any other Platform at all.

Noted on the bottom of the TreeGadget help page.

Sorry, you'll have to find a workaround around this whole Control to be
crossplatform compatible at the moment.

The whole point is that I do not want workarounds... I would like native support with PureBasic.

Regardless, this was posted for Fred. If everyone else wants to use workarounds that is fine, but this is my own little personal wish.

But this is a PureBasic related shortcoming not OS related.
On my LINUX box I can have Treeviews all over the place 8O

QUESTION:
Is PureBasic moving from a all purpose language to a Gamer language

If yes, than the Linux version needs years from now to have the same GUI toolkit as the Windows version.

I don't think so, I think PB is just expanding and growing just like any language should.

Post by **Fred** » Sun May 18, 2003 11:58 pm

No it's not moving into a game langage, but into a multipurpose langage which is fairly different.
