B4J Question Setting B4XTable lblSort.TextColor

[aeric]

Error:

B4XTable1.lblSort.TextColor = xui.Color_Blue

Okay:

Sleep(0)
B4XTable1.lblSort.TextColor = xui.Color_Blue

 

[PaulMeuris]

In my testcase the TextColor setting of the lblSort of the B4XTable1 works fine without the sleep command.
What error do you get?

I get object not initialized.

 

[PaulMeuris]

Which object?
It might help if you show the error log and maybe a piece of code...

Move the setting to the B4XPage_Appear and it will work. At that time the table is set up properly.
I have added some test data.

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    B4XTable1.Clear
    B4XTable1.AddColumn("first", B4XTable1.COLUMN_TYPE_TEXT)
    Dim data As List
    data.Initialize
    Dim rec As List
    rec.Initialize
    rec.Add("test")
    data.Add(rec)
    B4XTable1.SetData(data)
End Sub
Private Sub B4XPage_Appear
    B4XTable1.lblSort.TextColor = xui.Color_Red
End Sub

Yes, I understand that the B4XTable may not ready. It is similar to hiding the pnlHeader.

B4XTable pnlTitle.Visible pnlHeader.Visible can't set to False

In example "Cross platform Editable B4XTable + Form" add only one line Private Sub B4XPage_Created (Root1 As B4XView) 'original example code B4XTable1.pnlHeader.Visible=False 'my line End Sub Get error: "java.lang.RuntimeException: Object should first be initialized (B4XView)." What...

Moved to the questions forum.

B4XTable is internally loading a layout in its DesignerCreateView sub. This requires adding Sleep(0) inside B4XTable and this means that you also need to add Sleep(0) before you can access its views. This is a common issue / limitation of custom views that internally load layouts.

I get it.
