B4J Question Java jdk-11.0.3 display problems

[Robert Valentino]

When I compile with Java \jdk-11.0.3 my TreeTableView Display looks like this (Notice the Arrows are overlaying the text item)

But when I use jdk1.8.0_201 the display is fine.

Is there a reason that the jdk-11.0.3 version is causing this?

I didn't realize B4J didn't support Java 11 (https://www.b4x.com/android/forum/threads/b4j-v6-80-beta-with-support-for-java-11.99541/#content)

How is the link to an old beta version related to this discussion?

Your right, my bad. I am using 8.5 and that is 6.8 sorry was thinking the next version would be 8.6 the old age and dyslexia set in. Sorry

No problem. Worth testing with OpenJDK 14. The download link is available here: https://www.b4x.com/android/forum/t...lest-way-to-distribute-ui-apps.99835/#content

Same problem with OpenJDK 14

Is this because I am using a Label for my column display?
Is there anyway to offset the Label when it displays in the column?

As a temporary fix I am putting a TAB before the text when I create my label, which make everything look right

Not exactly the same as with java 8 (tab indents a little more), but something I can live with until there is a fix.

Private Sub CreateTextLabel(TextToShow As String, SetColor As Boolean) As Label
            Dim MakeLabel As Label
    
            MakeLabel.Initialize("")
            MakeLabel.Font    = fx.DefaultFont(18)
            
#if _Fixed_            
            MakeLabel.Text    = TextToShow
#else
            MakeLabel.Text    = TAB &TextToShow
#end if            
            
            If  SetColor Then
                MakeLabel.TextColor = fx.Colors.Blue
            End If
    
            Return MakeLabel
End Sub

Looks like you need to set the padding yourself with Java 11+. This is simple:

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("Layout1")
    MainForm.Show
    For i = 1 To 10
        Dim t As TreeTableItem
        Dim lbl As Label
        lbl.Initialize("")
        lbl.Text = i
        CSSUtils.SetStyleProperty(lbl, "-fx-padding", "0 0 0 20") '<-------
        t.Initialize("", Array(lbl))
        Dim t2 As TreeTableItem
        t2.Initialize("", Array(i))
        t.Children.Add(t2)
        TreeTableView1.Root.Children.Add(t)
    Next
End Sub

Thanks so much. That works perfectly.
