Can I convert QML to JavaScript?Can I convert QML to JavaScript?The QML engine has built-in support for converting a number of Qt types to related JavaScript types, and vice-versa, when transferring data between QML and C++. This makes it possible to use these types and receive them in C++ or JavaScript without needing to implement custom types that provide access to the data values and their attributes.Data Type Conversion Between QML and C++ Qt QML 5.15.2(plate) Qt QML Base Types Qt Quick 5.15.3

QML Type Registration in Qt 5.15

Let's look at the basic "Adding Types" example. In Qt 5.14 and before, the example had the following line of code in its main.cpp file qmlRegisterType<Person>("People", 1,0, "Person"); This would register the C++ class "Person" as a QML element also called "Person", into the module "People" under the version 1.0.

TableView QML Type Qt Quick 5.15.3

Since Qt 5.13, if you want to hide a specific column, you can return 0 from the columnWidthProvider for that column. Likewise, you can return 0 from the rowHeightProvider to hide a row.
