How to disable the Strict Equality Comparison warning

mrjj

Hi
For which compiler?

Often yes you can.

@mrjj
I use MSVC and MinGW.

When you compile, does it then show the warning id in output ?
like -Wuninitialized etc

I need something more than "Strict Equality Comparison" to find the key as
i only get javascript hits on that term so Im not sure which you actually want to supress.

Cab you list the actual warning you get ?

The solution is something like
QMAKE_CXXFLAGS += -Wno-enum-compare

but we need to know the actual thing it complains about so we kill the right one :)

@mrjj
No, It show as line annotations.
Error code is M126.
I don't have any problems that I can't compile, but I asked because it bothers me while coding.

Ah that is the clang code model.
https://doc.qt.io/qtcreator/creator-clang-codemodel.html

You can either disable the plugin completely
https://forum.qt.io/topic/100762/qt-creator-clang-code-model-problems-collection

Or go to option and c++ / code model and see if you can add remove it.
(often you can tool tip the warning and it tells what option)

Just make a copy of current default settings then you can change it.

Then go look
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html

and see if sounds like the warning.

I understood well, but I couldn't find description of strict equality comparison in Warning Options.

Hi
Can you give me a code snippet that gives that warning ?
Then maybe I can get hint from that ?

w.tkm

@mrjj
It's an extreme example,

property int i

    Component.onCompleted: {
        i = Math.floor(Math.random() * 10)
    }

    onClicked: {
        if( inputText.text == i ){ //M126 is shown here
            console.log("OK")
        }
        else {
            console.log("NO")
       }
    }

I know why it's showing.

@w-tkm why don't you do a proper comparison, instead of disabling the warnings ?

if( parseInt(inputText.text) === i )
//or
if(inputText.text === i.toString())

or the lazy way:

inputText.text === "" +i

@w-tkm

aahhh in QML :)

I'm afraid you cannot configure it.

You could try to force int conversion:

onClicked: {
        if( parseInt(inputText.text, 10) === i) ){ 
            console.log("OK")
        }
        else {
            console.log("NO")
       }
    }

Or to disable the warning:

 onClicked: {
        // @disable-check M126
        if( inputText.text == i ){ 
            console.log("OK")
        }
        else {
            console.log("NO")
       }
    }

@mrjj
Oh,sorry...I should have told you earlier...

@KroMignon
Thanks. I did it.
It seems to there is no setting in the options.

Do mean a global disable of this warning?
AFAIK, there is no way to do it.
But warnings are there to help you the write clean QML code, as QML is a declarative language, it is hard to be sure to write a clean code, so warnings are welcome to highlight not "so clean code" ;)

it worked for me, thanks a lot.. .
