Functionally, a button has a mouse sensitive area and a label. We start our text editor by building a button. The C++ portion of this tutorial assumes that the reader possesses basic knowledge of Qt's compilation procedures.ĭefining a Button and a Menu Basic Component - a Button To launch the text editor, merely provide the included qmlviewer tool with the QML file as the argument. This will put the C++ plugin in a directory where the QML files may find it. You may need to compile the C++ plugin in the examples/tutorials/gettingStarted/gsQml/ first. The final source code is in the examples/tutorials/gettingStarted/gsQml directory. Utilizing QML and Qt C++, we can efficiently decouple the interface logic from the application logic. Using Qt's Meta-Object System, we can expose C++ functions as properties that QML elements can use. For the second part, file loading and saving will be implemented using Qt C++. The first part will involve designing the application layout and behaviors using declarative language in QML. The application we are building is a simple text editor that will load, save, and perform some text manipulation. Qt Quick includes a declarative language called QML, the Qt Declarative Module, and QML Viewer. The installation guide contains installation instructions and requirements for different platforms. Installationįirst, we would need to install the latest version of Qt that includes Qt Quick, which is Qt 4.7. After reading this guide, you should be ready to develop your own applications using QML and Qt C++. In this Getting Started guide, we will create a simple text editor application using QML. Welcome to the world of QML, the declarative UI language.
