Button in PanelGadget

[milan1612]

Hey guys,



Does anybody know how to place a little button right there where the arrow points to?
Many Texteditors and IDEs use this to provide ability to close a Panel Item.

Any ideas?

EDIT: BTW "Unbenannt" means "Unknown"

Interesting little challenge, I think I covered all the bases:

Code: Select all

;- 
Procedure _subclass_cb_(hWnd,uMsg,wParam,lParam)
   
   oldProc = getprop_(hWnd,"TCOldP")
   
   If #WM_LBUTTONDOWN = uMsg
      hti.TC_HITTESTINFO
      hti\pt\x  = (lParam & $FFFF)
      hti\pt\y  = (lParam >> 16 & $FFFF) 
      item = SendMessage_(hWnd,#TCM_HITTEST,0,@hti)
      If hti\flags & #TCHT_ONITEMICON
         RemoveGadgetItem(GetDlgCtrlID_(hWnd),item)
      EndIf 
   EndIf
  
  ProcedureReturn CallWindowProc_(oldProc,hWnd,uMsg,wParam,lParam)
EndProcedure

;- 
Procedure main()
	
   hWnd = OpenWindow(0,#PB_Ignore,#PB_Ignore,640,480,"leer",#WS_OVERLAPPEDWINDOW)

   closeButton = CatchImage(0,?close_bmp_Start,?close_bmp_End-?close_bmp_Start)
   
   CreateGadgetList(hWnd)
   PanelGadget(0,0,0,640,480)
   For i = 0 To 4
      AddGadgetItem(0,i,"item "+Str(i),closeButton) 
   Next
   
   oldProc = setwindowlong_(GadgetID(0),#GWL_WNDPROC,@_subclass_cb_())
   Setprop_(GadgetID(0),"TCOldP",oldProc)
   
   Repeat
      event = WaitWindowEvent()
      
   Until event = #PB_Event_CloseWindow
	
EndProcedure:main()
