Compile source code into native machine code, accelerate start-up time and UI performance, and protect your source code and intellectual property. Qt Quick Designer is a WYSIWYG editor for files written in Qt QML, a CSS and JavaScript-like multi-paradigm language.
Keeping this in consideration, A QML app using Qt Quick Controls and a C++ class to provide a fully-functional rich-text editor application. The Text Editor Example presents a sample HTML file using the TextArea control, preserving the HTML formatting. Next, Welcome to the world of QML, the declarative UI language. In this Getting Started guide, we will create a simple text editor application using QML. After reading this guide, you should be ready to develop your own applications using QML and Qt C++. First, we would need to install the latest version of Qt that includes Qt Quick, which is Qt 4.7. Indeed, JavaScript can easily be used in QML to respond to events. Being a strongly typed language, C++ is best suited for an application's logic. Typically, such code performs tasks such as complex calculations or data processing, which are faster in C++ than QML. Qt offers various approaches to integrate QML and C++ code in an application. Similarly, To launch the text editor, merely provide the included qmlviewer tool with the QML file as the argument. The C++ portion of this tutorial assumes that the reader possesses basic knowledge of Qt's compilation procedures. We start our text editor by building a button. Functionally, a button has a mouse sensitive area and a label.
