When i want to change the image on the PanelGadget(), i use this method.
I don't know if it is the best, but ...

Code: Select all

Img1 = CreateImage(#PB_Any,16,16)
StartDrawing(ImageOutput())
Box(0,0,16,16,RGB($0,$FF,$0)) : Circle(8,8,8,RGB($0,$0,$FF))
StopDrawing()

Img2 = CreateImage(#PB_Any,16,16)
StartDrawing(ImageOutput())
Box(0,0,16,16,RGB($FF,$0,$0))
StopDrawing()

Img3 = CreateImage(#PB_Any,16,16)
StartDrawing(ImageOutput())
Box(0,0,16,16,RGB($FF,$0,$FF))
StopDrawing()

If OpenWindow(0,0,0,322,220,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"PanelGadget")
  If CreateGadgetList(WindowID(0)) 
    PanelGadget     (0,8,8,306,203) 
    AddGadgetItem (0,-1,"Panel 1", UseImage(Img1)) 
    AddGadgetItem (0,-1,"Panel 2", UseImage(Img2)) 
    ButtonGadget(2, 10, 15, 80, 24,"Button 1") 
    ButtonGadget(3, 95, 15, 80, 24,"Button 2") 
    CloseGadgetList()
  EndIf
  
  ; I get the ImageList of the PanelGadget()
  hImageList = SendMessage_(GadgetID(0),#TCM_GETIMAGELIST, 0, 0)
  ; I change the image (s)
  ImageList_Replace_(hImageList, 1, UseImage(Img3),0)
  ImageList_Replace_(hImageList, 2, UseImage(Img1),0)
  
  Delay(3000) ; Just for see the change.
  
  ; And i apply the ImageList at the PanelGadget()
  SendMessage_(GadgetID(0),#TCM_SETIMAGELIST,0,hImageList)
  
  Repeat
    Select WaitWindowEvent()
      Case #PB_Event_CloseWindow : Quit =  #True
    EndSelect
  Until Quit
EndIf

Another way, for to change the image of the selected tab.
The selected tab have a green image, and all the unselected tabs have a red image.

Code: Select all

Img1 = CreateImage(#PB_Any,16,16)
StartDrawing(ImageOutput())
Box(0,0,16,16,RGB($0,$FF,$0))
StopDrawing()

Img2 = CreateImage(#PB_Any,16,16)
StartDrawing(ImageOutput())
Box(0,0,16,16,RGB($FF,$0,$0))
StopDrawing()


Global Img1,Img2,Img3,Img4, SelectedItem

Procedure ChangeImage(Index) ; change image on the fly
  ;dÃ©clare TC_ITEM structure, and set Mask to #TCIF_IMAGE
  pitem.TC_ITEM
  pitem\Mask = #TCIF_IMAGE
  
  pitem\iImage = 1 ; Index of the image for selected tab
  SendMessage_(GadgetID(0), #TCM_SETITEM, Index, @pitem)
  
  pitem\iImage = 2 ; Index of the image for unseleted tab
  SendMessage_(GadgetID(0), #TCM_SETITEM, SelectedItem, @pitem)
  
  SelectedItem = GetGadgetState(0) ; New value for selected tab
EndProcedure


If OpenWindow(0,0,0,322,220,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"PanelGadget")
  If CreateGadgetList(WindowID(0)) 
    PanelGadget     (0,8,8,306,203) 
    AddGadgetItem (0,-1,"Panel 1",UseImage(Img1))
    AddGadgetItem (0,-1,"Panel 2",UseImage(Img2)) 
    AddGadgetItem (0,-1,"Panel 3",UseImage(Img2)) 
    AddGadgetItem (0,-1,"Panel 4",UseImage(Img2)) 
    ButtonGadget(2, 10, 15, 80, 24,"Button 1") 
    ButtonGadget(3, 95, 15, 80, 24,"Button 2") 
    CloseGadgetList()
  EndIf
  
  SelectedItem = GetGadgetState(0)
  
  Repeat
    Select WaitWindowEvent()
      Case #PB_Event_CloseWindow : Quit = 1
      Case #PB_EventGadget
        Select EventGadgetID()
          
          Case 0 ; call the ChangeImage procedure
            ChangeImage(GetGadgetState(0))
        EndSelect
    EndSelect
  Until = Quit = 1
EndIf

updated version for PB4.20 PB4.30
- this function updates only one panelgadget in your window.

Code: Select all


Procedure UpdatePanelIcons(panel) ; change panel images on the fly
   ;check index and selectedItem
   Static SelectedItem=-1
   If SelectedItem=-1
      SelectedItem=GetGadgetState(panel)
      ProcedureReturn
   EndIf
   Protected Index=GetGadgetState(panel)
   If Index=SelectedItem : ProcedureReturn : EndIf
   
   ;declare TC_ITEM structure, and set Mask to #TCIF_IMAGE
   Protected pitem1.TC_ITEM
   Protected pitem2.TC_ITEM
   pitem1\Mask=#TCIF_IMAGE
   pitem2\Mask=#TCIF_IMAGE
   
   ;get images
   SendMessage_(GadgetID(panel), #TCM_GETITEM, Index, @pitem1)
   SendMessage_(GadgetID(panel), #TCM_GETITEM, SelectedItem, @pitem2)
   
   ;swap images
   Swap pitem1\iImage, pitem2\iImage
   SendMessage_(GadgetID(panel), #TCM_SETITEM, Index, @pitem1)

Do you know how to transfer a tab icon from a panelgadget to an other one ?

I don't understand what you mean with 'transfer', but two panelgadgets can use the same image.

I'm coding a drag'n'drop function for panelgadgets. http://www.purebasic.fr/english/viewtopic.php?t=34590
I need to copy an tab icon in my drop function.

Panel1 ---> tab + text + icon --> Panel2

Stupid question (I didn't try) : copying the tab info with #TCM_GETITEM from the 1st panel and pasting it with #TCM_SETITEM in the 2nd panel doesn't work ?

#TCM_SETITEM will only update the image index to use.

Each panel have a specific imagelist.
The problem is to update these imagelists.

I will post a code sample to make some tests. It will be easier to see the problem

eddy wrote:#TCM_SETITEM will only update the image index to use.

If you know the image list [TCM_GETIMAGELIST] and the image index [TCM_GETITEM] in this list, iirc you can get the image handle with ImageList_GetImageInfo_().
So you can add the image handle to the 2nd panel image list and then use TCM_SETITEM.
I don't have PB available right now to test some code, sorry.

There is a kind of memory leak in Gnozal's procedure.
pitem\mask = #TCIF_IMAGE has to be set BEFORE the #TCM_GETITEM message is sent. Otherwise "pitem\iImage" is always 0 and every time the procedure is called an image is added to to Imagelist.

Here is a fixed version of Gnozal's code:

Code: Select all

Enumeration
  #Window_0
EndEnumeration
Enumeration
  #Panel_0
  #Button_0
EndEnumeration
Enumeration
  #Image_Panel_0_1
  #Image_Panel_0_2

    PanelGadget(#Panel_0, 16, 16, 262, 238)
      AddGadgetItem(#Panel_0, -1, "Tab #1", CatchImage(#Image_Panel_0_1, ?Image_Panel_0_1))
        ButtonGadget(#Button_0,5,5,100,30,"Button")

      AddGadgetItem(#Panel_0, -1, "Tab #2", CatchImage(#Image_Panel_0_2, ?Image_Panel_0_2))
