Is there a way to get the x and y coordinates of individual lines of text within a gadget?

Just 2D in Windows. I want to determine on which entry within a list box the user did a right-click without having to select it first with a left-click.

I wonder if you mean in 3D…

Which OS? This will be highly OS specific.

I'm not sure how you could get text width in purebasic but y is pretty simple. It's just font size. If you want to get the height of multiple lines then it's just font size multiplied by the number of new lines in your string

Try this out:
(heavily based on old code by Rashad!)

Code: Select all


Procedure WndProc(hWnd, uMsg, wParam, lParam)
  itemh = SendMessage_(GadgetID(6), #LB_GETITEMHEIGHT, 0, 0)      
  
  Select uMsg
    Case #WM_CONTEXTMENU
      Select wParam
        Case GadgetID(6)               
          GetCursorPos_(p.POINT)
          ScreenToClient_ (GadgetID(6), @p)
          Debug "x: " + p\x
          Debug "y: " + p\y
          index = Int(p\y/itemh)       
          
          Debug "Gadget 6  Item "+Str(index)
          
      EndSelect
      
  EndSelect
  
  ProcedureReturn #PB_ProcessPureBasicEvents
EndProcedure


OpenWindow( 0, 0, 0, 620, 510, "TEST", #PB_Window_SystemMenu | #PB_Window_ScreenCentered )

ListViewGadget( 6,        20,  90, 280, 260, #PB_ListView_MultiSelect )
For x = 0 To 4
  AddGadgetItem(6, -1, "TEST")
Next

SetWindowCallback(@WndProc())

Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow

SetWindowCallback(0)
