Disable QSlider's valueChanged on keyboard arrow keys

[sayan275]

How can I disable QSlider's emitting SIGNAL valueChanged on keyboard arrows and mouseWheel scroll. By setting

ui->horizontalSlider->setFocusPolicy(Qt::NoFocus);

the keyboards arrows keys are not emitting signals.

How can I do the same for mouse wheel scroll? I don't want to reimplement my custom Slider class from QSlider. Am asking for any work around or api, so that I can disable the keyboard and mouse wheel scroll responding to qslider.

The main intention is to avoid sending signals on every valueChange. So I have implemented the following and it's working fine

on_horizontalSlider_sliderReleased()
on_horizontalSlider_sliderPressed()

based on bool flag updated in these 2 slots,

on_horizontalSlider_valueChanged(int)

is doing the required operation...like after slider released, value is being added in the required application.

Request to provide approaches, examples for the work around.

Hi,

Wouldn't disabling the tracking property do what you want ?

Tried..but it didn't help

EventFilter is the option.
