Drag slider without having to directly click the slider handle.

[ealione]

If one wants to change the slider value then he can either click somewhere within the slider, or grab the slider handle and drag it around.

What I want to achieve is a sort of a mixed behaviour where I can perform a handle drag by clicking and dragging anywhere in the slider and not just exactly above the handler.

Is there an option or flag that will allow me to do this?
