GetGadgetItemAttribute() with #PB_ListIcon_ColumnWidth

[infratec]

Dear Team,

it looks that the procedure GetGadgetItemAttribute(GadgetNo, 0, #PB_ListIcon_ColumnWidth, i)
is not reliable.
But I can not find out on what it depends.
On my PCs it works correct.
On Demivecs PC with the same OS and the same SP it returns something but not what it should.
Please look here: http://www.purebasic.fr/english/viewtop ... 12&t=40457

This was also noticed in the german forum:
http://www.purebasic.fr/german/viewtopic.php?t=14364

But the windows API function seems to work always correct:
SendMessage_(GetWindow_(GadgetID(GID),#GW_CHILD),#HDM_GETITEMCOUNT,0,0)

It is not cross platform.

Please check this

Hmm, I don't understand your post :
. #PB_ListIcon_ColumnWidth returns the width of the given column
. #HDM_GETITEMCOUNT counts of the items in a header control (no native PB function iirc : maybe this is your wish ?)
These are two different things.

Hi gnozal,

What I want:
I want to get the numbers of columns of the ListIconGadget.
Since there is no direct PB solution, I tried to find it out with the
GetGadgetItemAttribute() procedure.
The idea: increase the columnnumber until it returns 0 or -1.

the API stuff it's not from me.
It's the latest answer from the german forum entry.

But I just checked it, and it returns the number of the columns.
So it does what I want... but not in a cross platform PB way.

Thanks, I understand now.
You wish a native (multi-platform) HDM_GETITEMCOUNT like function.

Why not just doing something like this for adding columns?

Code: Select all

Global f=1
Procedure AddListIconColumn(gadget, Position, text.s, width)
  AddGadgetColumn(gadget, Position, text, width) : f+1
EndProcedure

f-1...for removing columns.

In a Includefile or UserLib for other Users you haven't access to the creation of Colums

I do not think it give column without text.

Code: Select all

Procedure GetGadgetColumnCount(Gadget)

  Protected index
  
  index = -1
  
  Repeat
    index + 1
  Until GetGadgetItemText(Gadget, -1, index) = ""
  
  ProcedureReturn index
   
EndProcedure

Why do you think so? I use often column without title.

[Marco2007]

Maybe, something like this:

Code: Select all

Procedure CountListiconColumn(gadget, maxcolumn, keyword.s)
If IsGadget(gadget)
  AddGadgetColumn(gadget, maxcolumn, keyword, 0)
    For i=0 To maxcolumn
      If GetGadgetItemText(gadget, -1, i)=keyword
        Break
      EndIf    
    Next
  RemoveGadgetColumn(gadget, i)
  ProcedureReturn i
EndIf
EndProcedure

If OpenWindow(0,0,0,400,550, "",#PB_Window_SystemMenu|#PB_Window_ScreenCentered)
    ListIconGadget(0,20,0,365,500, "1", 90,#PB_ListIcon_GridLines)
    For j = 1 To 100
      AddGadgetColumn(0, j, Str(j+1), 90)
    Next
    
    For j = 1 To 10
      AddGadgetItem(0,-1,"Links"+Str(j) + #LF$ + "Mitte" + #LF$ + "Rechts")
    Next
    
Debug CountListiconColumn(0, 32767, "__thiscolumnwillbejustaddedtocountthecolumns__@@__unique_name__1234567890")
  
  Repeat ;
    EventID=WaitWindowEvent()
  Until EventID=#PB_Event_CloseWindow

EndIf

> I want to get the numbers of columns of the ListIconGadget.

then this is a feature request, not a bug report.

[infratec]

Hi freak,

this was only an explanation what I want to do.
Than I found that the GetGadgetItemAttribute() with #PB_ListIcon_ColumnWidth procedure
has a 'bug' (not working on all platforms as expected)

So in my opinion it is a bug, and nothing for the wishlist.

Bernd

P.S.: A happy new year!

Oh, it's already back in the bug section. Sorry

The attribute is not intended for counting the columns. If you use it for the wrong purpose you shouldn't be surprised if it doesn't work.
