如何更改自定义字体的文字大小？

Question

I've uploaded my own font in eclipse like this:

Font buttonFontDefault = Font.loadFont(MenuView.class.getClassLoader().getResourceAsStream("res/font/niagra_eng.TTF"), 100);

And it works just fine. The only problem I have, is that the only way of changing the text size, of buttons and labels written with this font, is to make a new font where the only difference is the size in the end of the code. I also tried the following:

button.setScaleX(0.50);
button.setScaleY(0.50);

The code above works, but then it ruins my GridPane layout, because the gridpane acts according to the original button size. I'd rather have a solution without any use of css, but if that's not a possibility then I guess I have no other choice. But why shouldn't there be a solution without css?

I haven't been able to find any help in the internet so far. Any help is greatly appreciated.

If you want to handle the fonts programmatically you can do it like @ItachiUchiha suggested by defining the font size when loading the font:

Font.loadFont(String name, double size)

The drawback of this method - as well as handling it programmatically at all - is that for each font size you will require a font instance handled by your code.

A cleaner solution in my opinion is to handle the fonts through CSS. Starting with Java 8, the font families can be defined through CSS:

@font-face {
    font-family: 'Roboto';
    src: url('Roboto-Medium.ttf');
}

.text {
    -fx-font-family: "Roboto";
    -fx-font-size: 18px;
}
