According to the docs, you can use a max of 5 buttons. The screen seems to just ignore any additional if you try to add more.

Up to 5 user-defined buttons may be displayed. Buttons are displayed in the order they are added and always appear in a fixed region of the screen

I too would like the option to have more in some cases.

You can show more than 5 buttons.

If you do a “More Options” button, catch Buttons’s Event, do a screen.ClearButtons() and Add more.

Actually I’m using a script to manage button pages…


Function ShowButtons()
  
  'Define functions
  obj = {
    defineButton:   defineButton
    prepareButtons: prepareButtons
    renderButtons:  renderButtons
    
    ButtonIdx:    []
    ButtonFnc:    []
    ButtonTxt:    []
    ButtonOrd:    []
    
    Count:       0
  }

  return obj

End Function

Function defineButton(param1, param2)
  m.ButtonOrd.Push(param1)
  m.ButtonTxt.Push(param2)
  m.Count = m.Count+1
End Function

Function prepareButtons()
  ' Calculate total pages
  if m.Count < 6
    float_pages = 1
    int_pages = 1
  else
    float_pages = (m.Count / 4)
    int_pages = int(m.Count / 4)
  end if
  
  diff_pages = float_pages - int_pages
  if(diff_pages > 0) and (diff_pages < 1)
    int_pages = int_pages + 1
  end if
  
  n = 1
  j = 1
  m.ButtonFnc[1] = []
  m.ButtonIdx[1] = []
  
  for i = 0 to m.Count-1
  
    if (int_pages > 1)
      if (n > 1 and n < int_pages)
        ' Show three options
        if (j < 3)
          m.ButtonIdx[n].Push("Less Options")
          m.ButtonFnc[n].Push(98)
        end if
        
          m.ButtonFnc[n].Push(m.ButtonOrd[i])
          m.ButtonIdx[n].Push(m.ButtonTxt[i])

        if (j > 3)
          m.ButtonIdx[n].Push("More Options")
          m.ButtonFnc[n].Push(99)
          j = 1
          n = n + 1
          m.ButtonIdx[n] = []
          m.ButtonFnc[n] = []
        end if

      else if (n = 1)
        ' Show four options
        m.ButtonIdx[n].Push(m.ButtonTxt[i])
        m.ButtonFnc[n].Push(m.ButtonOrd[i])
        
        if (j > 3)
          m.ButtonIdx[n].Push("More Options")
          m.ButtonFnc[n].Push(99)
          j = 1
          n = n + 1
          m.ButtonIdx[n] = []
          m.ButtonFnc[n] = []
        end if
        
      else
        ' Show four options
        if (j = 2)
          m.ButtonIdx[n].Push("Less Options")
          m.ButtonFnc[n].Push(98)
        end if

        m.ButtonIdx[n].Push(m.ButtonTxt[i])
        m.ButtonFnc[n].Push(m.ButtonOrd[i])
      end if
    else
    
      ' Show five options
      m.ButtonIdx[n].Push(m.ButtonTxt[i])
      m.ButtonFnc[n].Push(m.ButtonOrd[i]) 

    end if
    j = j + 1
  end for
  
end function

function renderButtons(screen, page)
  screen.ClearButtons()
  for i = 0 to m.ButtonIdx[page].count()-1
    screen.AddButton(m.ButtonFnc[page][i], m.ButtonIdx[page][i])
  end for
end function

Example: How to use it


Function Springboard()
  screen = CreateObject("roSpringBoard")
  port = CreateObject("roMessagePort")

  screen.SetMessagePort(port)

  buttons = ShowButtons()

  buttons.defineButton(1, "View video")
  buttons.defineButton(2, "View Trailer")
  buttons.defineButton(3, "Add to wishlist")
  buttons.defineButton(4, "Show synopsis")
  buttons.defineButton(5, "Coupon Redeem")
  buttons.defineButton(6, "Option 6")
  buttons.defineButton(7, "Option 7")
  buttons.defineButton(8, "Option 8")
  buttons.defineButton(9, "Option 9")
  buttons.defineButton(10, "Option 10")

  buttons.prepareButtons()

  page = 1
  buttons.renderButtons(screen, page)

  screen.Show()

  while true
    msg = wait(0, screen.GetMessagePort())
    if(msg.isButtonPressed())
      if (i = 98)
        ' Less Options
        page = page - 1
        buttons.renderButtons(screen, page)
      else if (i = 99)
        ' More Options
        page = page + 1
        buttons.renderButtons(screen, page)
      end if
    end if
  end while
end function

I hope this helps :wink:

NOTE: This script allows manage up to 6 pages… i don’t need more than 3.

It’s still 5 buttons at a time.

I know, but you can manage more than 5 buttons and much people don’t know this is possible
