描述

I'm working on an application which mainly consists for sliders for parameter control. For better user experience, it would be nice to offer two features: reset to default and fine control.

On VST plugins this is normally done via double-clicks and/or modifier keys. E.g. double-clicking resets the slider to a default (mostly 0), alternatively Ctrl-/Cmd-Klick also does it. For fine control, often Shift-dragging is used. Fine control is useful in cases where the slider covers a large value range with only little screen space.

Is there a way to add such functionality with the existing code via traits or would that require an update to the widgets?

研究方向
Examine the slider widget implementation in the iced codebase, likely under src/widget/slider.rs or similar. Understand how mouse events and modifier keys are currently handled. Check for existing trait patterns (e.g., Widget trait) that could be extended to add custom behavior. Look for any existing comments or PRs that discuss similar features.
