    It's a pseudo-class. You can't use it as a style-class.

    Copy code
    tableRowCell {
     odd {
            and(hover) {
                backgroundColor += Color.BLUE
            }
     }
}

    that was in my first example, it highlights the cell rather then the row (if i remove the odd/even the entire row was highlighted)

    Oh, sorry. I misunderstood the question 🙂

    I thought you were getting cell highlighting and you wanted highlight on hover

    Interesting. Code looks ok to me. I will have a look at the TableView once I am back in sometime.

    @Rob There is a small detail which is incorrect in your code.

    odd
    and 
    even
    should actually be pseudo-classes

    try this:
    Copy code
    tableRowCell {
    and (odd) {
        backgroundColor += Color.BLUE
        and(hover) {
            backgroundColor += Color.YELLOW
        }
    }
    and (even) {
        backgroundColor += Color.RED
        and(hover) {
            backgroundColor += Color.YELLOW
        }
    }
}

    Hey all. I'm trying to get an ImageView to display my Image, and in Java you do this as follows:
  • s

    S

    07/23/2018, 3:52 PM
    @S uploaded a file: Untitled
    -.js

    Unfortunately, toURI doesn't seem to work; it shows up as an unresolved reference and IntelliJ doesn't suggest any imports to fix this, so I assume there aren't any. How could I get an Image from my File without this function?

    That's an alternative way to create Image and ImageView objects from bytes. I suspect your problem is that you don't actually have a URI (ex, file:///C/users/carl/myfile.txt) but instead have a fully-qualified path (C:/users/carl/myfile.txt)

    selectedFile
    ?

    it can't be a 
    File
    if IntelliJ won't resolve toURI() https://docs.oracle.com/javase/8/docs/api/java/io/File.html#toURI--

    @S it sounds like you're importing your image from a file in your computer - IMO it might be better to save the image in your resources so you never have to worry about your placement.

    @S i.e. I created an 
    img/
    folder and:
    Copy code
    private val tiles = listOf("/img/Tile1.png", "/img/Tile2.png",
            "/img/Tile3.png", "/img/Tile4.png", "/img/Tile5.png",
            "/img/Tile6.png").observable()

    @Gary Tierney I'm importing Java.io.File, but it won't resolve toURI. I don't know why.

    then 
    selectedFile
    isn't a 
    File
    object, so what is it declared as?
  • s

    07/23/2018, 5:15 PM
    a File? object

    oh ok, then you just need to add a null check

    Copy code
    if (selectedFile != null) {
    myImageView.setImage(selectedFile.toURI().toString());
}
