How to access C++ enum from QML?

Question

class StyleClass : public QObject {
public:
    typedef enum
        {
            STYLE_RADIAL,
            STYLE_ENVELOPE,
            STYLE_FILLED
        }  Styl         


        

Answer 1

Additional information (not documented prior to Qt 5.5):

Your enum value names must start with a Capital letter.

This will work:

enum EnStyle
{
    STYLE_RADIAL,
    STYLE_ENVELOPE,
    STYLE_FILLED
};
Q_ENUMS(EnStyle)

This does not:

enum EnStyle
{
    styleRADIAL,
    styleENVELOPE,
    styleFILLED
};
Q_ENUMS(EnStyle)

You won't get any kind of error at compile time, they are just ignored by the QML engine.
