B4J Code Snippet Tableview header wrap text

SubName: SetTableHeaderWrap

Allows the table view header text to wrap.

Sub SetTableHeaderWrap(Table As JavaObject, PrefHeight As Int)

    Dim HeaderRow As Pane = Table.RunMethod("lookup",Array("TableHeaderRow"))
    For Each N As JavaObject In HeaderRow.GetAllViewsRecursive
        If N Is Label Then
            Dim NL As Label = N
            If PrefHeight <> -1 Then NL.PrefHeight = PrefHeight
            'Seems to lose the text centering
            CSSUtils.SetStyleProperty(NL,"-fx-text-alignment","center")
            N.RunMethod("setWrapText",Array(True))
        End If
    Next
End Sub

Set the PrefHeight to -1 to leave it unchanged.

Nice. I recommend using CSSUtils.SetProperty instead of appending the attribute to the style. The advantage of CSSUtils.SetProperty is that it will replace the existing attribute (if such exists).
