Please consider switching to RichTextArea incubator module in JavaFX 24
Nearly all Java text editors, Swing and FX alike, suffer from one deficiency: inability to work with large data models, such as logs or query results.
The goal of this project is to provide a professional FX text component that is capable of handling billions of lines, provides syntax highlighting, multiple carets and multiple selection, rich text capabilities, embedded images and embedded components.
The main idea which allows for all these features is separation of the editor and underlying data model. The data model then can be made as simple as a contiguous in-memory byte array, or as complex as memory-mapped file with a concurrent change log that enables editing of a very large files.
- supports up to 2^31 lines of text
- multiple selection and carets
- supports syntax highlight
Requires JavaFX 21+.
The project is at a very early stage: less than 29% of all identified features is currently implemented.
To see how little is implemented, launch FxEditorApp.java
public class MainWindow extends FxWindow
{
public MainWindow()
{
super("TestFxEditorWindow");
setTitle("FxEditor Demo");
setSize(600, 700);
// data model
FxEditorModel m = new TestFxColorEditorModel();
// editor component is a Pane
FxEditor ed = new FxEditor(m);
ed.setMultipleSelectionEnabled(true);
// add to layout
setCenter(ed);
}
}See MainWindow.java
