In included file: unknown type name 'QCustomPlot"

[Louysa]

I have a project which is recently been working well, today I tried to open that project but it is now giving me an error like this

And also in the header file, this error comes up:

What should I do? I am new at QT please give me help. I have other projects in which I used qcustomplot in those also.

Hi and welcome to devnet,

Is it the code model that is complaining or is your build failing as well ?

[Louysa]

@SGaist I don't understand what you mean, can you ask more clearly?

[SGaist]

Can you build your application successfully ?
If so, what you are seeing is the code model complaining and it might get wrong sometimes.

[Louysa]

@SGaist no I can not build my application successfully right now

Same error?

[Louysa]

@jsulm yes

[SGaist]

@Louysa what does your qcustomplot.h contain ?

[Louysa]

@SGaist I solved it, idk how but I changed my qscreen file with my current code and both have the same code right now I delete qscreen and replaced it with the correct one it is working now. Sorry

[SGaist]

@Louysa qscreen file ? Can you explain what you did ?
