[Leaningtech-dev] [Bug 1393017] Re: error:Field not supported in union.

[blueshell]

Ok I just find out that , it does not support struct.
but i did not find the tips on wiki.

if i change the type using static_cast instead of union, is the Cheerp
supported?

here are my test file.


// The cheerp/clientlib.h header contains declarations
// for all the browser APIs. 
#include <cheerp/clientlib.h>


class Event
{
public:

        struct sMouseEventStruct
        {
                int windowX;
                int windowY;
                int stageX;
                int stageY;
                int mouseId;
                int mouseKey;
                float pressure; //0-1
        } ;

        struct sKeyboardEventStruct
        {
                int keyCode;
                float pressure; //0-1
                int deviceId;
        };

        struct sUserEventStruct
        {
                int userData0;
                int userData1;
                int userData2;
                int userData3;
                int userData4;
                int userData5;
                int userData6;
                int userData7;
        } ;

public:

        Event (){};
public :
        int type;
protected:
        union
        {
                struct sMouseEventStruct _MouseEvent;
                struct sKeyboardEventStruct _KeyboardEvent;
                struct sUserEventStruct _UserEvent;
                
        } param;
public: 
        Event (int evtid)
        {
                type = evtid;
        }

        struct sUserEventStruct* getUserEventStruct()
        {
                return &param._UserEvent;
        }

        const struct sUserEventStruct* getUserEventStruct() const
        {
                return &param._UserEvent;
        }

};

// webMain is the entry point for web applications written in Cheerp.
void webMain()
{
    Event e;
    // client is a C++ namespace that contains all browser APIs 
    client::console.log("Hello World Wide Web!");
}
