Hi,

I would like create a sub menu where I use Check Menu Items.

Something like this:

Settings
ComPort->
Com1
Com2​


My plan was to make a submenu where I create Check Menu Items for the serial ports available,

I can not figure the menu system out. Anyone know how to make this?

I tried to do some thing like this.
B4X:
Private mnuComPort As Menu
    mnuComPort.MenuItems.CheckMenuItems.AddAll(Serial1.ListPorts)

You cannot add strings as menu items.



This code will help you get started:
B4X:
Sub Process_Globals
   Private fx As JFX
   Private MainForm As Form
End Sub

Sub AppStart (Form1 As Form, Args() As String)
   MainForm = Form1
   MainForm.Show
   Dim mb As MenuBar
   mb.Initialize("")
   MainForm.RootPane.AddNode(mb, 0, 0, 0,0)
   Dim ports As Menu
   ports.Initialize("Ports", "")
   Dim FileMenu As Menu
   FileMenu.Initialize("FileMenu", "")
   mb.Menus.Add(FileMenu)
   FileMenu.MenuItems.Add(ports)
   For Each m As String In Array As String("a", "b", "c")
     Dim mm As MenuItem
     mm.Initialize(m, "mm")
     ports.MenuItems.Add(mm)
   Next
End Sub

Sub mm_Action
   Dim mi As MenuItem = Sender
   Log(mi.Text)
End Sub

Hi,

Now I maybe know why I am a little confused.

I have taken this part from your code:

B4X:
For Each m As String In Array As String("a", "b", "c")
    Dim mm As MenuItem
    mm.Initialize(m, "mm")
    mnuComPort.MenuItems.Add(mm)
    Next
and put into mine.

This works only in "Release" not "Debug"

In debug:


Program started.

No, that works perfect :)

I have made the Menubar, Settings menu and ComPort menu with Scene Builder. Can this be the problem.
I think it is strange it works in release and not debug.

B4X:
    For Each m As String In Serial1.ListPorts
    Dim mm As CheckMenuItem
    mm.Initialize(m, "mm")
    mnuComPort.MenuItems.Add(mm)
    Next
I got this to work thanks to you :) See attached dumb

Hi,

I have another problem with this,

I would like to store the chosen com port in a settings file. I can do that when I click on the comport in the menu.

But when the program start again I have to set com port number stored in the settings file

I can :
B4X:
For Each m As String In Serial1.ListPorts
    Dim mm As CheckMenuItem
    mm.Initialize(m, "mm")
    mnuComPort.MenuItems.Add(mm)
    Next
  
    mm.Selected = True
But it just select the last in the array.

How do I find the one stored in my settings file and select it, and unselect if other is selected ?

Yes. There is a known issue in v1.06 with nested menu items. It is fixed for the next update.

B4X:
For Each m As String In Serial1.ListPorts
    Dim mm As CheckMenuItem
    mm.Initialize(m, "mm")
    mnuComPort.MenuItems.Add(mm)
    If m = ValueLoadedFromFile Then mm.Selected = True
   Next
