In Qt6 QStateMachine (and the other similar classes) belong to the QtStateMachine submodule, no longer to the QtCore submodule, so add QT += statemachine to the .pro.

It seems that in Qt6 the names are more restrictive than Qt5 in the names so you should use "Material" instead of "material".

ModuleNotFoundError: No module named 'pandas' in Qt Creator

Asked 2021-Mar-04 at 16:26

I recently created my first qt quick2 pyside application, I had a python class with the name TestClass that I had used before in visual studio with no error, I decided to use this class in qt quick pyside application but it has below error:

QtCreator is probably using a different python than the one you installed pandas. The solution is to use the correct python for this go to Tools-> Options-> Python and select the correct path.

QUESTION

QSqlQuery::lastInsertId doesn't work with MS Access

Asked 2020-Sep-15 at 08:53

I work with MS Access database (.accdb) and I need to insert some data and then get the last inserted ID. When I use QSqlQuery::lastInsertId method I see the following error:
"QODBCResult::lastInsertId: not implemented for this DBMS" Error: ""
I tried to use SELECT @@IDENTITY and similar expressions (SCOPE_IDENTITY and IDENTITY_CURRENT), but I get the same error.
Some time ago I used SELECT @@IDENTITY in VBA and that worked. So it's not about MS Access, but the driver?
Of course, I can write SELECT MAX(ID) FROM table, but I'm not sure it's safe.
Is there a way to get the last inserted ID working with MS Access database?

Answered 2020-Sep-15 at 01:21

I don't recognize the syntax in your various unsuccessful examples.

SELECT MAX(ID) FROM table will work assuming ID is incremental; your concern as to whether this is 'safe' I don't understand what is meant ....

If there is not a reliable incrementing ID field then typically one would add a date/time field with default value Now() which is of course incrementing - and use the Max of this field.

QUESTION

Qt::Concurrent mapped with a member function

Asked 2020-Jun-04 at 17:37

I want to use the QtConcurrent::mapped() function, but going through the QtConcurrent examples provided and trying to find a usable example to extend to my use has been difficult.

In the examples, Qt maps to static functions only, no member functions are used (many simliar mapped variations are found in the examples, but no member functions are used).

The problem:

QtConcurrent::map() applies a function to a Sequence or Iterator w/o returning i.e. QFuture. However I wish to have the results returned i.e. QFuture from a member function.

The example/scenario I want to use it in is an intensive workload in a UI application, but a simplied example could be:

ANSWER

Answered 2020-Jun-02 at 17:06

416 bytes in 1 blocks are possibly lost in loss record 8,318 of 8,856

The message is possibly lost, that means the Widget is still reachable, this is not a definitive memory leak like in int * x=new int; x = NULL;

You have that message because when your program finishes you did not deleted/freed all the allocated dynamic memory, that does not means your program is wrong.

Look at definitely lost blocks, if you do not have all is ok in fact. For that you can use the option --show-leak-kinds=definite which is equivalent to do --show-reachable=no --show-possibly-lost=no
