Widget MouseHoverEvent Disable

[mrjj]

Hi
What do you mean?
So when the user hover mouse over a Widget, then its disabled ?
You could use an event filter to catch the hover event

Since Qt's CSS does not support any enabled/disabled attribute to use for the :hover pseudo-state you will have to do it in code by subclassing QWidget and using the enterEvent/leaveEvent methods.

I have a problem When SerialPort read 5 megabit widget form on mouse hover crcCalculate error
I want to disable Widget on mousehover disable
How Can I and why get I crc calculate widget form on mousehover

@alonewolfsemmmy
No idea what your latest question means.... Nor why serial port/custom plot widgets have the faintest connection to mouse hover, other than you needing to write whatever code you need to write....

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.

Hi
This function
https://doc.qt.io/qt-5/qwidget.html#enabled-prop

[alonewolfsemmmy]

@mrjj please I didn't you said Please tell me example thank you my friend

[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 ?
