Question: Getting font size of the CodeArea

[KoblizekXD]

Hello, I'm currently building an application which requires me to use CodeArea and I would like to implement mouse wheel scrolling zoom, therefore I need to get a actualy font size and increase/decrease it. I didn't find any method to get that, as getFont() doesn't seem to exist. From what I've yet understood, the font size value can be stored in CSS like this:

.styled-text-area .text {
    -fx-font-size: 24pt;
}

But I'm not really sure how could I retrieve it! I will be grateful for any response! Thanks!

@KoblizekXD I would do it this way:

.styled-text-area .text {
    -fx-font-size: 1em;
}
....
textArea.setStyle("-fx-font-size:" + size);

By other words you need to keep size in some variable.

I see what you mean. The thing is now, that I would like to change font size of the actual text when zooming, using CodeArea#setStyle won't work as expected. It will only change the size of line numbers, but not the text itself. How can I do that?

This can't be done using CodeArea because it extends StyleClassedTextArea which uses CSS style classes that cannot be changed dynamically. To do what you want (using the technique suggested by @PavelTurk) you need to use InlineCssTextArea instead but creating your own CodeArea to extend that is not straightforward.

An alternative idea is to maybe set the scale on the CodeArea instead ?
