Hi

but widget mousehover when crccalculate error How Can I fixed

This sentence dont really tell what is wrong.

Also what is crccalculate ?

Maybe a picture will help us understand what you need to fix or do ?

@mrjj
When I hover over the widget with the mouse while reading the serial port data, I get an error in the Crc32 calculation. That is, when the mouse moves, while reading the serial port at a speed of 5 megabits

@alonewolfsemmmy

Ok, that way. well you could set the button to disabled so remove the hovering effect but
it sounds very odd that such a small effect would give you CRC errors.

[alonewolfsemmmy]

Okay How Can I you said please help me for example code:
ui->pusbutton ? thenk you

[JonB]

@alonewolfsemmmy
Example code for what? And we expect you to write the code and ask questions, not just ask others to write it for you.

[alonewolfsemmmy]

No button to disabled so remove the hovering effect How Can I
I don't know how to turn off the button hovering effect
Please help me My friend I need your help

[JonB]

@alonewolfsemmmy
No, you need to do some reading of the documentation, try some things, and write questions which people can understand, even if English is not your native language.

[alonewolfsemmmy]

[mrjj]

hi
Its very helpful to be able to use the docs.
anyway, try
ui->buttoname->setEnabled(false);

the button should show a bit grey and no hover effect.

@mrjj
You said didn't work I want to widget on mousehover disable effect widget
All Right Have you advice CRC-32/MPEG-2 calculate function because When I move on widget form Crc 32 calculate error What Can I fixed

[mrjj]

@alonewolfsemmmy
Hi
That is hard to guess on as why would a hover eefct break the CRC calculation in first place ?

Did you watch your cpu usage ? is it at 100% ?

[alonewolfsemmmy]

Okay my brother I will try you said cpu usage

[alonewolfsemmmy]

@mrjj my brother
SerialPort 5 megabit buadrate cpu Usage

[mrjj]

@alonewolfsemmmy

Ok so its not using 100% cpu so its not due to the hover disturbs it.

Does it happen every time if you hover something?

Do you use StyleSheets in your app ?

[alonewolfsemmmy]

@mrjj said in yes it happen every time if you hover something

I dont use stylesheets in my App

[mrjj]

@alonewolfsemmmy

Ok so its not due to the stylesheet which can be heavy.

And what happened when you disabled the button ?
It went grey looking and no hover effect ?

[alonewolfsemmmy]

@mrj MyBrother

When I disabled the button nothing has changed

[mrjj]

@alonewolfsemmmy
Not even the button ?
It should be disabled unless something in code turns it on again.
