How disabled few properties for class on one OS

shav

Hi everyone!

I'm developing application for few platforms (Desktop and Mobile). My application has a special property in class which supports only one OS (OSX) and I want to disable it for other OS. How I can do it correct? I try this:

#if defined(Q_OS_OSX)
    Q_PROPERTY(NestleanWebSocketManager* webSocketManager READ getWebSocketManager)
#endif

But I receive this errors when I trying build:

tmp/mocs/moc_nestleanrequestmanager.cpp:234:65: error: use of undeclared identifier 'NestleanWebSocketManager'
            *reinterpret_cast<int*>(_a[0]) = qRegisterMetaType< NestleanWebSocketManager* >(); break;
                                                                ^

            *reinterpret_cast<int*>(_a[0]) = qRegisterMetaType< NestleanXcodeHelper* >(); break;

What I do wrong?

Thanks for the any help.

Hi,

When are you getting that error ?

shav

@SGaist I'm receiving this error every time when I trying build my application for iOS. I want disable'webSocketManager' property for iOS.

Hi everyone!

Small updates. Today I've try do this on old version of Qt (5.7 Beta 1). Now I use 5.7 RC1 and the result is:
If I trying build my project on Qt 5.7 Beta 1 all works fine. But if I trying build my application on the Qt 5.7 RC1 I have the problem for this topic. I think this is a bug in MOC system.

If someone know how to fix this let me know. Thanks!

HI everyone!

I found the problem. I'm using incorrect macros for detect platforms. I'm trying use something like this:

#if (defined(TARGET_OS_IPHONE) && TARGET_OS_IPHONE)
    #define NESTLEAN_MOBILE
#elif defined(__ANDROID__)
    #define NESTLEAN_MOBILE
#else
    #define NESTLEAN_DESKTOP
#endif

or

#if defined(Q_OS_IOS) || defined(Q_OS_ANDROID)
    qDebug()<<"MOBILE";
    Q_INIT_RESOURCE(resources);
#else
    qDebug()<<"DESKTOP";
    Q_INIT_RESOURCE(resources);
#endif

Both ways generate errors which I post in my first post. So, question is how I can detect platform if I use mobile (Android and iOS) and Desktop (OS X, Windows, Linux)?

SGaist

Just to be sure I understand correctly: starting with 5.7RC

class MyClass : public QObject
{
    Q_OBJECT
#ifdef Q_OS_IOS
    Q_PROPERTY(QString whatever READ whatever)
#endif

public:
#ifdef Q_OS_IOS
    QString whatever() const { return "something"};
#endif
};

fails to build ?

shav

No. I use another macros.

#if defined(Q_OS_OSX) || defined(Q_OS_LINUX) || defined(Q_OS_WIN)
//code here 
#endif

But As I understand the Q_OS_LINUX is defined for Linux and android. And this is my problem.
For now I found solution to use pro file with DEFINES += MOBILE (for mobile) and DEFINES += DESKTOP (for desktop). But as I understand it's not best solution.

By the way. On another mac when I have Qt 5.7 Beta1 I also don't install android SDK. And this conditions is works. But If I install SDK for Android it's doesn't work. Maybe I do something wrong.

You can use the reverse logic:

#if defined(Q_OS_ANDROID) || defined(Q_OS_IOS)
// mobile stuff
#else
// desktop stuff
#endif

shav

I tried this logic (../Helpers/nestleanconstants.h):

#if defined(Q_OS_ANDROID) || defined(Q_OS_IOS)
    #define NESTLEAN_MOBILE 1
#else
    #define NESTLEAN_DESKTOP 1
#endif

And header of class:

#ifndef NESTLEANREQUESTMANAGER_H
#define NESTLEANREQUESTMANAGER_H

#include <QtCore>
#include <QtNetwork>

#include "../Helpers/nestleanconstants.h"

//Others headers

#if defined(NESTLEAN_DESKTOP)
#include "WebSocket/nestleanwebsocketmanager.h"
#endif

class NestleanRequestManager : public QObject
{
        Q_OBJECT
        Q_CLASSINFO("version", "1.1")

        Q_PROPERTY(NestleanApplicationRequestsManager* appManager READ getAppManager)
        //other properties
#if defined(NESTLEAN_DESKTOP)
        Q_PROPERTY(NestleanWebSocketManager* webSocketManager READ getWebSocketManager)
#endif

    private:
    //some code

#if defined(NESTLEAN_DESKTOP)
        NestleanWebSocketManager* m_webSocketManager;
#endif

    public:
    //some code

#if defined(NESTLEAN_DESKTOP)
        inline NestleanWebSocketManager* getWebSocketManager() { return m_webSocketManager; }
#endif

    signals:

    public slots:
};

#endif // NESTLEANREQUESTMANAGER_H

Errors the same. I can't understand why it happens.
