Modify ListViewGadget - can it be done

[RamRat]

Hi,

Is there any way to have a ListViewGadget only show the Items and no scrollbar or border etc. or do I have to write my own?

I want this so I just see a list of items floating on screen that looks clean and simple, will be using my Surface Pro to flick
the list up/down or select item.

Cheers!

Ok I have sussed the no border bit after searching the forum so now just need to get rid of the scrollbar

SetWindowLongPtr_(GadgetID(2), #GWL_EXSTYLE, GetWindowLongPtr_(GadgetID(2), #GWL_EXSTYLE)&~#WS_EX_CLIENTEDGE) ; NO BORDER !!!!

Is there a similar piece of code to get rid of the scrollbar or a modification to the above line ?

Hi RamRat,

I made a little Demo of a TouchListControl a few years ago.
The code is a mess, because it was just to proof if and how easy it could be done.
Also I made a cleaned up version as include later on, but shame on me - I cannot find it anymore.

But maybe it's if some worth for you.
Hint: In Line 141 you should change '0.98' into '0.997' to get a better (Phone-like) scrolling experience.

Hi

Code: Select all

LoadFont(0,"Tahoma",12)
If OpenWindow(0, 0, 0, 400, 200, "ListViewGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
  SetWindowColor(0,$D3FFFF)
  ContainerGadget(0,10,10,380,175,#PB_Container_BorderLess)
    ListViewGadget(1, -1, -1, 402, 182)
  CloseGadgetList()
  SetGadgetFont(1,FontID(0))
  SetGadgetColor(1,#PB_Gadget_BackColor,$D3FFFF)
  For x = 1 To 30
    AddGadgetItem (1, -1, "Item " + Str(x) + " of the Listview")
  Next
  SetActiveGadget(1)
  SetGadgetState(1,0)

  Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
  EndIf

You might find it easier to achieve with a ListIcon

Awesome! Thanks mate. works just how I want !

Now... does anyone have answers/ideas for ListViewGadget questions

1. It works fine on touchscreen BUT can it be forced to scroll smoother ?
2. When an item is selected can the selected items font change colour and not the background? (I tried "SetGadgetState(2,-1)" kinda works but doesn't remove all traces of item selection....)
3. Anyone have an idea how to hack a fadein/fadeout onto the top and bottom of the ListViewGadget

Cheers!

What is different with ListIcon that makes it easier? oh... will ListIcon provide a smoother scroll?

Cheers!

No, it's simply that ListIcon is more often used, and thus whatever you want to do has probably been done before and the code posted on the forum. Take a look at RS Basic's Win API Lib, lots of Windows API for the ListIcon are documented there.
http://www.rsbasic.de/winapi-library/ You can download it too. ListIcon could be viewed as a 'plus' version of a ListView.

For ListIon or ListView, it might be possible to control scroll smoothness using a SCROLLINFO structure. I have never done this myself but there is probably some code on the forum.
