hi

i need help to find the correct logic to get what i need. i am using this tool to get some information from a bal file:


this tool is converting a complete bal file to json file so it gets all information from each view like colors, position, size, name etc.
what i need is just get from each view 5 parameters.

Name
Left
Top
Width
Height

i dont need the json file so i am trying to get the info directly from the created map that holds all information.

the structure of the map look as follow.

first, there is a map that hold all parameters of a single view. if the view has children then it holds also a map with the key ":kids"
this map will hold again a map of maps that each map will hold all parameters and again if it has children it will also hold a key ":kids"
if not it wont.

now i am able to get all views with the parameters but not the kids and their kids.

i try for 2 days to find a logic how to do that. it needs to be something that is recursive like this code:

what i have until now is this. change just one sub in the balconvertor class and add 1 sub:

B4X:
Public Sub ConvertBalToJsonInMemory(Dir As String, FileName As String) As Map
    Dim reader As RandomAccessFile
    reader.Initialize2(Dir, FileName, True, True)
    Dim design As Map
    Dim lh As Map = ReadLayoutHeader(reader)
    If lh.Get("Version") < 3 Then
#If UI
        Dim xui As XUI
        xui.MsgboxAsync("Unsupported version: " & FileName, "")
#end if
#If NON_UI
        Log("Unsupported version: " & FileName)
#End If
        Return design
    End If
    design.Initialize
    design.Put("LayoutHeader", lh)
    Dim cache() As String = LoadStringsCache(reader)
    Dim numberOfVariants As Int = reader.ReadInt(reader.CurrentPosition)
    Dim variants As List
    variants.Initialize
    For i = 0 To numberOfVariants - 1
        variants.Add(ReadVariantFromStream(reader))
    Next
    'design.Put("Variants", variants)
    'design.Put("Data", ReadMap(reader, cache))
    'reader.ReadInt(reader.CurrentPosition) '0
'    design.Put("FontAwesome", reader.ReadSignedByte(reader.CurrentPosition) = 1)
    'design.Put("MaterialIcons", reader.ReadSignedByte(reader.CurrentPosition) = 1)

    reader.Close
    Return design
End Sub

    myitem.name = m.Get("name")

this is exactly what i need, i just need now to get all kids in the panels and if there are also panels with kids get them to so something that is recursive.

i attach a sample bal file and the convertor i have.

thanx in advance
