Property to turn on and off line wrapping

[jeffreyguenther]

As requested by @TomasMikula, can we get a method like:

setLineWrapping(true);

to turn on and off the line wrapping for the control?

[TomasMikula]

I can implement line wrapping relatively easily (TextFlow already supports it), but note that it divorces the notions of a visual line and a logical line. A logical line will be visually rendered as a paragraph, i.e. multiple visual lines. Up/Down arrow navigation currently works on logical lines, so a single Up/Down arrow press could have the effect of skipping a number of visual lines. It will take some more effort to implement navigation on visual lines.

[TomasMikula]

It's now implemented, including the navigation within wrapped lines (up to some quirks). Please report if you observe them as annoying.

Looking forward to seeing a rich-text editor built on top of CodeArea!

Thank you @TomasMikula!

You turn it on by area.setWrapText(true);.

Hi Maher.

InlineStyleTextArea is a more general version of InlineCssTextArea.

With InlineCssTextArea, you provide style information as a String:

inlineCssTextArea.setStyle(from, to, "-fx-font-weight: bold;");

With InlineStyleTextArea, your style information can be any object, as long
as you also provide a function (that's the extra constructor parameter) to
convert it to CSS. For example

class StyleInfo {
    private boolean bold = false;
    private boolean italic = false;

    public void setBold(boolean bold) { this.bold = bold; }
    public boolean isBold() { return bold; }

    public void setItalic(boolean italic) { this.italic = italic; }
    public boolean isItalic() { return italic; }
}
StyleInfo emptyStyle = new StyleInfo();

InlineStyleTextArea<StyleInfo> area = new InlineStyleTextArea<>(emptyStyle, style -> {
    String css = "";
    if(style.isBold()) css += "-fx-font-weight: bold;"
    if(style.isItalic()) css += "-fx-font-style: italic;"
    return css;
});

StyleInfo style = new StyleInfo();
style.setItalic(true);
area.setStyle(from, to, style);

Now, you might be wondering why would one ever create a class such as
StyleInfo above and not use the CSS string directly. While it is not very
useful when you are only setting styles, it becomes useful when you are
getting back the style at a given position in text. Note the
getStyleAt(int position);
method. For InlineCssTextArea, this returns the CSS string, which you would
have to parse to make any use of it. With InlineStyleTextArea, you get back
your StyleInfo instance, which is much easier to work with.

I hope this helped.

Regards,
Tomas

Hello Tomas,
I have been using the JavaFX with help from Jeff in trying to figure out a
way to apply different styles to sub-strings within a text area.
Thanks for developing CodeArea. This is really helpful. I started to
explore it and I have a few questions for when you have time (I am new to
Java--please forgive my possibly very primitive questions):

I noticed that now there are two classes: InlineCssTextArea and
InlineStyleTextArea. The difference is mostly in the object creation (given
different constructors), is that correct? Are there other major difference
that I am missing somewhere?

I am currently trying clean up the conceptual framework for the
implementation. Hopefully after the holiday will start working on it again
and show you a cool prototype.

Thanks for your help on this :) and have a great holiday!

Hi Tomas thank you very much for The detailed explanation. :)
This is very helpful.
I'll report back on my progress.
Best,
