How can I disable deprecation warnings altogether ?

A workaround could be to disable them and only from time to time enable 
and check if there are deprecations to fix.




IIRC, by defining QT_NO_DEPRECATED_WARNINGS.

It seems we have many ways to deprecate, but not to undeprecate a 
specific one ? I’m looking for something similar to Q_UNUSED() to get 
rid of a -Wunused-parameter warning




Just a random note: that blog post of mine is a bit outdated. A few 
things have been changed in Qt's deprecation mechanisms in the meanwhile
(warnings have been made versioned, deprecation warnings are enabled by 
default, and so on).


Anyway: there's unfortunately no solution to your issue except for 
disabling deprecating warnings altogether. For the record, I did propose 
to have special deprecation markers (special in the sense that you could 
enable/disable them independently from the other deprecation warnings) 
in Qt 5.15 for:


1) APIs that are deprecated in Qt 5 but without a replacement in Qt 5 
itself (but eventually only in Qt 6), like indeed QNCM (AFAICT), so for 
which having a warning is "useless" as there's nothing one can do about it;


2) APIs that exist in Qt 5.15.x only to ease the transition towards Qt 
6, i.e. are only meant to be used during a port, and absolutely not for 
"ordinary" development (like a lot of QStringView-related functionality 
in 5.15 which has been implemented by doing view.toString().foo(), i.e. 
throwing QStringView advantages out of the window).



The patches unfortunately were not merged before 5.15 was made closed 
source, so I gave up. You can find them in the relation chain here.

Is there any way in Qt Creator to only show me the places where Grandchild::foo() is 
called?  Right now, I'm finding that even if I go to grandchild.cpp, put my cursor on 
void Grandchild::foo(), and then select "Find Reference to Symbol Under 
Cursor", it shows me every instance of EVERY foo() called anywhere in the program, 
including the declarations/definitions of Abstract::foo(), Base::foo() and Child::foo(), 
which I don't care about at the moment.


By "every foo()" do you mean even the ones completely unrelated to your 
class hierarchy, or all the foo() in the hierarchy?


Anyhow, given it's a virtual, how can you know at compile time if you're 
calling GrandChild::foo() or not?


Abstract *blah = getFoo();
blah->foo(); // might call Grandchild::foo(), or not

I have no clue what this code does, nor do I see a way to even 
semi-mechanically switch to the suggested replacements.
Does anyone know how to get the desired behavior without using deprecated API?


The wrong deprecation APIs (the unversioned ones) have been used in 
qtbase when deprecating these methods. Please open a bug against Qt 5.14 
(?) to mark them with the versioned markers.

For me Ctrl+0 works as expected in the output panes.


Do you happen to know if this added recently? (On 4.9.1, cannot update 
right now...).

To be fair, it's not clear what those +- icons refer to, they are

I think an argument could be made for moving them by the Maximize 
button? Then where they are, should be the  < > buttons, which would 
follow the Find / Replace mini pane precedent.
