[Gambas-user] listbox display selected item

[Dimitris Anogiatis]

JY, I think I got it working the way you want it...

try my example with a new project with a listview and a timer. Set the timer
for 10 miliseconds and enable it

and paste this code in the class

-----------------------------------------------------------------------------------------------------------------------------------------------------

' Gambas class file

PUBLIC SUB _new()

END

PUBLIC SUB Form_Open()
Listview1.Add("Blah", "Hi there")
Listview1.Add("Blah2", "How are you")
Listview1.Add("Blah3", "I'm good")
Listview1.Add("Blah4", "How about you?")

END

PUBLIC SUB chooseSub(choice AS String)

  SELECT CASE choice
    CASE "Blah"
      PRINT ("Key is Blah")
    CASE "Blah2"
      PRINT ("Key is Blah2")
    CASE "Blah3"
      PRINT ("Key is Blah3")
   CASE "Blah4"
      PRINT ("Key is Blah4")
    CASE ELSE
  END SELECT

END

PUBLIC SUB ListView1_Click()

  chooseSub(Listview1.Item.Key)

END

PUBLIC SUB Timer1_Timer()

  'Listview1.Find(Mouse.ScreenX - fmain.ScreenX - Listview1.Left,
Mouse.ScreenY - Fmain.ScreenY - Listview1.Top)
  IF Listview1.Count > 0 THEN
     SELECT CASE Listview1.Find(Mouse.ScreenX - Fmain.ScreenX -
Listview1.Left, Mouse.ScreenY - Fmain.ScreenY - Listview1.Top)
      CASE FALSE
        Listview1[getKeyFromPosition(Listview1, (Mouse.ScreenY -
Fmain.ScreenY - Listview1.Top) \ 25)].selected = TRUE

      CASE ELSE
     END SELECT
  ENDIF

END

PUBLIC FUNCTION getKeyFromPosition(lv AS ListView, pos AS Integer) AS String
  DIM iterator AS Integer
  DIM tmpCount AS Integer

  DIM res AS String

IF pos <= 0 THEN tmpCount = 0
IF pos >= lv.Count THEN
   tmpCount = lv.Count - 1
ELSE
   tmpCount = pos
ENDIF

    lv.MoveFirst

      FOR iterator = 0 TO tmpCount - 1
       lv.MoveNext
      NEXT

    res = lv.Item.Key

  RETURN res
END

-----------------------------------------------------------------------------------------------------------------------------------------------------

be careful of all the events firing and the code executing... but I think I
got it as close to what you want it to do, as possible

hope this helps in your project

Keep up the good work

Regards,
Dimitris
