It's to do with this setting~~, but have not tried to see what effect they have, or even how to apply to the table~~.
http://docs.oracle.com/javafx/2/api/javafx/scene/control/TableView.html#UNCONSTRAINED_RESIZE_POLICY

I found a solution: ( you need to use the lib I wrote jScriptEngine)

B4X:

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private tab1 As TableView
    Private js As jScriptEngine  ' need to add this to libs
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("tabres1") 'Load the layout file.
    tab1.SetColumns(Array As String("One","Two","Three"))
    MainForm.Show
    js.enginePut("tab1",tab1)
    js.evalString("tab1.setColumnResizePolicy(tab1.CONSTRAINED_RESIZE_POLICY);")
End Sub

The result is you get three columns, not the default 'what you want plus one'.

Nice find

You can also apply it using JavaObject

B4X:

        Dim JO As JavaObject = Tab1
    Dim Policy As JavaObject
    Policy = Policy.InitializeStatic("javafx.scene.control.TableView").GetField("CONSTRAINED_RESIZE_POLICY")
    JO.RunMethod("setColumnResizePolicy",Array As Object(Policy))

Sorry my English is very bad.

And this piece of code where you're going?

Something like this:

B4X:

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private Tab1 As TableView
 
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("1") 'Load the layout file.
    Dim JO As JavaObject = Tab1 'Tab1 is a TableView defined in layout "1"
    Dim Policy As JavaObject
    Policy = Policy.InitializeStatic("javafx.scene.control.TableView").GetField("CONSTRAINED_RESIZE_POLICY")
    JO.RunMethod("setColumnResizePolicy",Array As Object(Policy))
 
    MainForm.Show
End Sub

No 1.0 !!

stevel05 · Jan 15, 2014

The Java Object has changed slightly in 1.06, along with other amendments and bug fixes, I suggest you download the latest version.

desof · Jan 15, 2014

OK

I never received the link to download

stevel05 · Jan 16, 2014

As B4j is free and the link is readily accessible, Erel doesn't send out links, just an announcement on the forum that a new version is available.
