Widget MouseHoverEvent Disable
-
Hello I want to disable widget on mousehover How Can I Can you help me
Thank you -
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 subclassingQWidget
and using the enterEvent/leaveEvent methods. -

@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.... -

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