Unsolved QList<const QBluetoothDeviceInfo* declaration / definiton problem

@J-Hilk Would it be too offensive to ask you to discuss this ?
PS I do not get notified about new posts so it may take a few days before I ;ll read your reply.

What do you want to discuss? Whether the documentation is lying?
You should not copy QObject.

Everything else, you can copy/use copy c'tors, as it's just standard C++ language and not "Qt".

@Pl45m4 I was looking for alternative way to make a copy of "info" and I got it solved. CLOSED

No, of course not, open discourse is one of the fundamentals of society.

I'm curious on what you now ended up using! But for your information I wanted to point out, that you can click on the cog symbol on your opening post and actually select "Mark topic as solved". Alternatively, if you think that one answer in particular solved your issue, you can mark that answer as the correct one.

@J-Hilk

Currently I just add "info" to struct - class variable and pass "info" to another function for( partial) processing.
I am still not sure if I can process multiple SIGNAL.

Here is a code snippet. PLEASE keep in mind it is a code under construction and I like to keep old code so I do not duplicate and of course I use QDebug extensively.
I am posting the cope "as is " PLEASE do not tell me it does not compile.

       void SettingsDialog::addDevice(const QBluetoothDeviceInfo &info)
       {
           // //*BT_Database_Array[16];
           //HERE
           BT_Database_Array[Array_Index].BT_INFO_Address = info.address();
           BT_Database_Array[Array_Index].INFO_Name = info.name();

           //Array_Index++;
           //#endif
           //temporary copy to QString
           INFO_Name = info.name();
           BT_Database.INFO_Name = info.name();
           BT_Database.INFO_Address = info.address().toString();
           // verify name
           text = " TASK  verify name";
           text += BT_Database_Array[Array_Index].INFO_Name;
#ifdef DEBUG_TASK_SCAN
           qDebug()<< text;
#endif
           text= "Read info ";
           text += " name ";
           text += info.name();
           text += " address ";
           text += info.address().toString();

#ifdef DEBUG_TASK_SCAN
           qDebug()<< text;
#endif

           // verify address
           text = " TASK  verify address";
           text += BT_Database_Array[Array_Index].BT_INFO_Address.toString();
#ifdef DEBUG_TASK_PAIRING
           qDebug()<< text;
#endif

           //Pairing_verify(0);
           Pairing_verify(0, info);

@Axel-Spoerl Hello sir, I wonder if I could ask you a favor which
would be immensely helpful in using QT.
I am looking forward to your reply.
Thanks
Cheers

@AnneRanch
Feeling honored to be addressed aristocraticly :-)
Just ask!

[AnneRanch]

@Axel-Spoerl OK - here it comes

is there a written document (QT ) describing how to setup QT to
compile ONCE ?

There are options but I must have them set incorrectly - "typical" user error...

I have a growing "subdirs" project and when I do "rebuild" and then "run" or "debug" it will compile again - without me doing any editing.

Same when I do edit , then "run " and "run" again, it compiles again , without me doing any more editing.

This redundant recompile is beginning to take more and more of my precious time ... I could spent with my grand kids instead ...

I had posted a bug report but got no solution.

@AnneRanch
I guess this is worth a thread of its own.
Generally, it is not the intention for Qt Creator to always recompile.
If the project is configured correctly, what you describe should not happen.
Troubleshooting depends on whether you use qmake or cmake.
Both build systems check time stamps to determine if a build tree is dirty and needs compilation.

Typical constellations that trigger rebuilding are

• git pull or git rebase in the source tree
• a build step in Qt Creator that triggers a cleanup before building
• broken subdir configuration

Suggest you post your subdir structure and cmake / .pro files in a separate thread.

@Axel-Spoerl Thanks , I did post "sarcastic" ...." it compiles" in "the lounge".

Maybe I could ask for it to be moved .....

and do as you suggested after
