@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.

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.

alonewolfsemmmy

Okay My brother So how can I disable the mouse thank you
