Constructors

ScrollY

#
public ScrollY(Canvas canvas, INestedScroller target)
Parameters:

Fields

Properties

ActiveRegion

public RectangleF ActiveRegion { get; }
Gets the active region for this scroller. If the mouse leaves the active region we assume the scrollbar ought to fade.
inherited fromScrollBar

Canvas

public Canvas Canvas { get; }
Gets the canvas this scroller is tied to.

Dragging

public bool Dragging { get; }

inherited fromScrollBar

Fading

public bool Fading { get; }
inherited fromScrollBar

Grip

#
public override RectangleF Grip { get; }
Gets the grip rectangle for this scrollbar.
Overrides: ScrollBar.Grip

HasFaded

public bool HasFaded { get; }
Gets whether this scrollbar has completely faded out and can be culled. Note that ValueNow is only meaningful after the animation has been evaluated at least once, and Draw() skips evaluation entirely while the grip is empty. A freshly created fade-in bar therefore also reports a ValueNow of zero, so we additionally require the bar to actually be fading out before declaring it dead.

public IEnumerable<(Guid id, float initialOffset)> ParallelScrollers { get; }
Enumerate over all parallel scrolling objects.
