    Is it possible to center align text in a textarea?

    I have used some formatting such as:

    Dim GameClock As TextArea
    GameClock.Style = 
    "-fx-font-size: 48; -fx-font-weight: Bold;"
    but I've not been able to find anything which will control alignment.

    I'd like both horizontal and vertical alignment, but would be happy with just horizontal alignment.

    I don't think that you can change the TextArea alignment. Why do you use TextArea instead of Label? Does it need to be edited?

    Thanks Roycefer, I did try without success:

    GameClock.Style = "-fx-font-alignment: center;"
    as per the reference, but I believe Erel is correct and control of alignment is not possible.

    I only used TextArea as it was already in a form I was using as a template for a new project, but as you suggest Erel, for my purpose a Label would be OK.

    Thanks for your support again.

    Erel I changed to use Labels and have used Rectangles to provide backgrounds of various colors. However I want to change the Rectangle color under program control, however none of the methods I've tried work.

    For instance I saw an example where a Rectangle was assigned as a JavaObject here http://www.b4x.com/android/forum/threads/add-rectangles-to-map-use-them-as-limits.48139/ which I thought may be the right direction, but when I:

    Dim jo As JavaObject = RinTeamFoulsRect
    it does not recognise RinTeamFoulsRect as a valid value even though I have set that as the ID in SceneBuilder.

    Do I need to set the ID some other way and what would the appropriate jo.RunMethod code to change the Rectangle Fill color?

    please try this example using JavaObject.

    Sub Process_Globals
    Private rechtangleMain As Node
    Dim joRect As JavaObject = rechtangleMain
    'Set the fill color to yellow
    BTW: Just in case, if has to be a textarea with centered text, this can be done by defining in the files folder a css file with following entry:
    .text-area *.text {
        -fx-text-alignment: center;
    Assign the css file as a stylesheet to the textarea. Tested this solution by using the JavaFX SceneBuilder.

    Thanks Robert.

    Your example works great and if I need to use TextArea in the future I'll try your other suggestion.

    Once again thanks for your support - I am continually amazed by the support this site offers users.
