[DarkoT]

Hi,

Code:

Private Sub SetFilterStyle(Index As Int, Color As String)
    
    Dim Style As String = " -fx-background-color: " & Color & ";"
    If Color = "" Then Style = ""
    Dim jo As JavaObject = tblView
    Dim columnHeader As JavaObject = jo.RunMethodJO("lookup", Array(".column-header-background"))
    Dim firstCell As JavaObject = columnHeader.RunMethodJO("getChildren", Null).RunMethod("get", Array(Index))
    firstCell.RunMethod("setStyle", Array(Style))
End Sub

    Dim firstCell As JavaObject = columnHeader.RunMethodJO("getChildren", Null).RunMethod("get", Array(Index))
    firstCell.RunMethod("setStyle", Array(Style))
End Sub

I found the solution - if somebody will need this...

Private Sub SetFilterStyle(Index As Int, Color As String)
    Dim Style As String = " -fx-background-color: " & Color & ";"
    If Color = "" Then Style = ""

    Dim jo As JavaObject = tblView
    Dim Column As JavaObject = jo.RunMethodJO("getColumns", Null).RunMethod("get", Array(Index))
    Column.RunMethod("setStyle", Array(Style))
End Sub
