Accessing C++ Element exposed for QML in C++
I want to create a new component which can be exposed to QML.
I figured out that the following lines would do the job:
main.cpp
- int main(int argc, char **argv) {
- ...
- Access access;
- ctxt->setContextProperty("access", &access);
- qmlRegisterType<TrayPaint>("TrayPaint", 1, 0, "TrayPaint");
- ...
- }
As shown above there is an object “access” which is also exposed to QML.
How can I implement that the object “access” can change properties or call functions of the instance of object “TrayPaint” used in QML?
I thought on something like the objectName-Property in QML. But I’m not shure.
The TrayPaint object should display a (dynamic) number of circles. Each circles gets a number and a color property. The color should be changeable from C++.

To expose a method from a C++ class to QML, you can use the Q_INVOKABLE [developer.qt.nokia.com] macro.
