Slider with detents?

[bovilexic]

I've got a request to have sliders with "detent" positions. Not sure if this is the best term, so here's the idea: say you have a slider that goes from -1 to 1, and you want the user to be able to reliably hit the "0" position, by making the slider knob/button "stick" somewhat to that middle point, as he is sliding close to that point.

I don't see anything in the way of Qt API or stylesheets that can be used to make this work. Any clever ideas, short of writing a new slider subclass (or if someone has done that work, lemme know)?

Thanks!

maybe you'd like to implement your own QYourSlider::mouseReleaseEvent() where you convert cursor position to slider value and if its value is within the range around your 'quantized' values, set slider position to it.

It might be easiest to just watch the valueChanged() event and if the value is within some epsilon of your "detent" position, manually set the value.

Thanks for the ideas!
