B4J Question Custom View Spectrogram - Working with TabPanes

[rgarnett1955]

Hi

I am designing a custom view using Hansolo heat maps. I can get it to work on the main layout, but not on Tabs.

I have attached a zip of the project including the charts-11.8.jar file to go in additional libs.

#Region Project Attributes
    #MainFormWidth: 1300
    #MainFormHeight: 950
    #AdditionalJar: charts-11.8
#End Region

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private xui As XUI
    Private Button1 As B4XView
    Private Spectrogram1 As Spectrogram
    Private tabPane1Obj As TabPage

    Private SpectrogramTab As Spectrogram
    Private TabPane1 As TabPane
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("Layout1")
    MainForm.Show
    Spectrogram1.plotSpectrogram
    
    Try
        SpectrogramTab.plotSpectrogram
    Catch
        Log("tab Spect error 1")
    End Try

    Try
        tabPane1Obj = TabPane1.LoadLayout("tabPane1", "Spectrograph")
    Catch
        Log("tab Spect error 2")
    End Try   
End Sub

The custom view code is:

#DesignerProperty: Key: BooleanExample, DisplayName: Show Seconds, FieldType: Boolean, DefaultValue: True
#DesignerProperty: Key: TextColor, DisplayName: Text Color, FieldType: Color, DefaultValue: 0xFFFFFFFF, Description: Text color

    Dim chart As JavaObject

    Private mLeft, mTop, mWidth, mHeight As Int
    Private pnlSpectrogram As Pane

    mEventName = EventName
    mCallBack = Callback
End Sub


'Base type must be Object

    mTop = mDummy.Top
    mWidth = mDummy.Width
    mHeight = mDummy.Height
    Tag = mDummy.Tag
    
    'we create a new mBase object to get the Touch event
    mBase = xui.CreatePanel("eventSpect")
    mParent = mDummy.Parent
    mParent.AddView(mBase, mLeft, mTop, mWidth, mHeight)
    mParent.AddView(pnlSpectrogram, mLeft, mTop, mWidth, mHeight)
    mBase.Tag = Me

    mBase.Tag = Me

I suspect the problem is with the designer create view which I lifted form the Custom View booklet, but I'm afraid I don't really understand what it does.

Can some one help me.

If I can get it working I will publish it on the forum so others can use it. The heat map does a good job although it's a bit slow.

Regards
Rob

Sorry,

Gave the tab pages the incorrect name. Fixed it, but it still does not work for the tab spectrum view.

I can't upload the charts-11.8.jar it's too big
