Is it possible to specify a font using CSS in JavaFX application? I have an FXML scene and the corresponding CSS file. In Java code, it's possible to specify a font using the setFont method:

text.setFont(Font.loadFont("file:resources/fonts/SourceSansPro-Bold.ttf", 12));

I tried different constructions, like:

-fx-font-family: url("../fonts/SourceSansPro-Bold.ttf");

But it doesn't work.

I use a combination of application code and CSS to style via an external font.

I place the loadFont call inside an overridden Application init method to make sure it is invoked before anything much happened in the application.

Font.loadFont(CustomFontTest.class.getResource("TRON.TTF").toExternalForm(), 10);

To use the font, I reference the font by font family in CSS:

.menu-bar {
    -fx-background-color: transparent;
    -fx-font-family: TRON;
    -fx-font-size: 40px;
}

.context-menu {
    -fx-font-family: TRON;
    -fx-background-color: transparent;
    -fx-font-size: 12px;
}

Nice that the CSS sizes the fonts fine. Even when the font is loaded at size 10, the font was resized correctly to what is specified in the CSS -fx-font-size specifications.

Inline styling of a label via CSS using a Font loaded during application initialization also works fine:

Label testControl = new Label("TRON");
testControl.setStyle("-fx-font-family: TRON; -fx-font-size: 120;");

The TRON font was downloaded from dafont and placed in the same directory as the CustomFontTest class and copied to the build output directory by the build system.

Answer copied from my answer to a forum post on "Using Custom Fonts".

  • I've gotten it to work with `Font.loadFont(getClass().getResourceAsStream("TRON.TTF"), 10);` instead. :) – Keith OYS Nov 02 '17 at 14:15

You were close to the solution:

-fx-font-family: 'Helvetica', Arial, sans-serif;

Try this, it should work fine.

Maybe this could help? (I'm not an expert in JavaFX)

EDIT:

Load your font:

@font-face {
    font-family: Delicious;
    src: url('Delicious-Roman.otf');
}

Use your font with -fx-:

-fx-font-family: 'Delicious';

  • My question about external font, because I need to use my font, instead of using already installed on user system. – syscreat Aug 29 '12 at 08:24
  • same way. use `@Font-face` to load font and then in `-fx-font-family` you put the name of your font. – Andrea Turri Aug 29 '12 at 10:13
  • Though I haven't tested it, according to [this JavaFX tracking issue](http://javafx-jira.kenai.com/browse/RT-10343), @font-face support isn't scheduled to be added to JavaFX until JavaFX 8/JDK 8 timeframe. – jewelsea Aug 29 '12 at 17:03

    @AndreaTurri doesn't seem to work for me - tested in the latest v. of JavaFX Scene Builder. How did you test this? – XXL Mar 23 '13 at 14:11
  • @AndreaTurri it does *not* work in JavaFX 2.2! See the [JavaFX Jira issue](http://javafx-jira.kenai.com/browse/RT-10343) referenced by jewelsea for details. It was clarified that this is a JavaFX 8 feature only and there are no plans to backport to 2.2. See [jewelseas other answer](http://stackoverflow.com/a/12181948/1717169) for a proper way to load custom fonts in JavaFX 2.2 which actually works. – void256 Apr 09 '13 at 18:54
  • Remember to declare your `@font-face` first in the CSS for it to work! – smac89 Aug 13 '19 at 21:43

Just found out one more detail: In JavaFX-8 if you want to have regular and bold variants of the same font you can specify them with two instances of @font-face. Then you can use -fx-font-weight: bold;

@font-face {
    font-family: 'Droid Sans';
    src: url('DroidSans.ttf');
}

@font-face {
    font-family: 'Droid Sans Bold';
    src: url('DroidSans-Bold.ttf');
}

.root {
    -fx-font-family: 'Droid Sans'; 
}

.table-row-cell:focused .text {
    -fx-font-weight: bold;
}

Another way is to load font using FileIUnputStream, thus you don't need to use css:

 @FXML
    private Label myLabel;

@Override
    public void initialize(URL arg0, ResourceBundle arg1){

Font myFont = null;

        try {
            myFont = Font.loadFont(new FileInputStream(new File("patch_to_font.ttf")), 10);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

        myLabel.setFont(myFont);

}

  • The original question is about how to use this loaded fonr in CSS. Sure, you can load font file directly, but how you would like to use it in forms stylesheets? – syscreat Feb 16 '16 at 13:13
  • Oh, my bad. I had problems with using custom font in CSS, so this was my alternative solution. Anyway you're right - it's not related to this question. – RichardK Feb 16 '16 at 13:39

JavaFx CSS fonts (import .ttf):

/* import fonts */
@font-face {
    font-family: "Open Sans";
    font-style: normal;
    font-weight: 400;
    src: url("/fonts/OpenSans-Regular.ttf");
}
@font-face {
    font-family: "Open Sans Light";
    font-style: normal;
    font-weight: 300;
    src: url("/fonts/OpenSans-Light.ttf");
}
@font-face {
    font-family: "Open Sans Bold";
    font-style: normal;
    font-weight: 700;
    src: url("/fonts/OpenSans-Bold.ttf");
}
@font-face {
    font-family: "Open Sans ExtraBold";
    font-style: normal;
    font-weight: 900;
    src: url("/fonts/OpenSans-ExtraBold.ttf");
}

/* Set fonts */

.settings-name{
    -fx-font-size: 33px;
    -fx-font-family: "Open Sans Light";
    -fx-font-weight: 300;
    -fx-text-fill: #09f;
}

.settings-username{
    -fx-font-size: 19px;
    -fx-font-family: "Open Sans ExtraBold";
    -fx-font-weight: 900;
    -fx-text-fill: #09f;
}

You need to place the Font.ttf file in our bin/<main application> folder, that contains the .class of your application example
