Hello,

I want to create a "text field" in which the user can introduce Strings and then after a validation is executed some words will be highlighted/underline.
Also it should support text insertion at current cursor location, replace selection with inserted text. would also need a listener at text input.

I thought of using an javafx.scene.web.HTMLEditor but I'm not sure if it supports current selection replacement, or insert at current cursor position.

Also this component will be heavily used throughout my application, many of them will be displayed at the same time in the editor.

Does anyone have any advice on what should I use?

Thank you in advance for any help

Right both of them should work.

We (here at this forum) naturally only provide support for StyledText
and its friends.

Getting started if you use Eclipse is dead simple and explained at:
-
http://tomsondev.bestsolution.at/2015/07/23/defining-source-editors-with-a-dsl/
-
http://tomsondev.bestsolution.at/2015/07/24/developing-a-source-code-editor-in-javafx-without-e4-and-osgi/

We also have a list of features (eg hover-Tooltips, better navigation,
....) people might be interested but we require some funding for them.

Hi,
I tried using StyledTextArea but I have some problems with it:
The enter key does not have any effect, does not create a newLine,
The cursor is still blinking in the component after I select another StyleTextArea component.
The focus is received only when I make a click on the first line in the component

Am I missing something?
I just do
StyledTextArea textField = new StyledTextArea();
textField.getContent().setText("");
//set some height constrains
textField.setMaxHeight(GridPane.USE_PREF_SIZE);
textField.setMinHeight(GridPane.USE_PREF_SIZE);
textField.setPrefHeight(100);

the component is put in a GridPane, and each row has a new component inside.

Thank you

Hi,

Could you try with a none empty text from the start - there's a bug when
the text is empty :-(

The bug is fixed with https://bugs.eclipse.org/bugs/show_bug.cgi?id=477772.

I can not reproduce the problem with newlines. What OS and what version
of Java are you running?

Hi,
The problems persist even without an empty string at the beginning.

I'm using jre1.8.0_51 on Windows 7.

Regards,
Ionut

PS: maybe its important but my entire javafx component is wrapper in a FXCanvas, I am using javafx in a swt aplication.

To rule that out can you try creating a simple JavaFX application (no
osgi involved) using it? I'll give it a try later on on my windows10 vm,
my dev env is OS-X.

Hello Tom,

thank you very much for the quick answer.

I investigated a little bit further, we searched for the possibility to highlight text with a squiggle underline (use case is to highlight syntax errors).

It seems that such kind of underline is foreseen to be supported in your widget but not implemented in the styled text renderer (maybe due to a limitation in JavaFX?).

Is this understanding correct?

Best regards,
Stefan

The StyledTextArea does support underlineing

..underlinedText {
-efx-decoration: underline;
}

..underlinedText > Line {
-fx-stroke: red;
}

We currently only have a very simple default strategy available (see
UnderlineStrategyFactory) but you can contribute your own (for fun we
internally once wrote a fire-underline which really looks cool on dark
backgrounds).

Caveat: The current annotation stuff from the text-infrastructure does
not use that support
