Full text editor component


KTextEditor provides a powerful text editor component that you can embed in your application, either as a KPart or using the KF5::TextEditor library (if you need more control).

The text editor component contains many useful features, from syntax highlighting and automatic indentation to advanced scripting support, making it suitable for everything from a simple embedded text-file editor to an advanced IDE.



As with other KParts, you should use KParts::MainWindow as your main window. You can directly request "katepart", as in

if (service) {
m_part = service->createInstance<KParts::ReadWritePart>();

See the KParts documentation for more information on using KParts.


If you are using CMake, you need to have

1 find_package(KF5TextEditor)

(or similar) in your CMakeLists.txt file, and you need to link to KF5::TextEditor.

After that, you can use KTextEditor::Editor to create an editor instance, and use that to manage KTextEditor::Document instances.

#include <KTextEditor/Document>
#include <KTextEditor/Editor>
#include <KTextEditor/View>
// create a new document
// create a widget to display the document
KTextEditor::View *view = doc->createView(containerWidget);

See the documentation for these classes for more information.
