获取NSScroller的滚动条位置 [英] Get scroll bar position of an NSScroller on the fly

问题描述

紫色矩形是 NSView 。在其 awakeFromNib 方法中，我调用 [[NSViewController alloc] initWithNibName：@nibbundle：nil]] / p>

红色矩形是 NSScrollView aka @nib。此视图包括垂直滚动条。

绿色框是一个 NSBox nib，由 NSCollectionViewItem 。

滚动列表时，如何观察和获取滚动条旋钮的位置（即拖动旋钮）？

感谢您的帮助：）

解决方案

>完全重复，答案与此处相同：如何检测NSOutlineView的滚动？

The purple rectangle is an NSView. In its awakeFromNib method I call [[NSViewController alloc] initWithNibName:@"nib" bundle:nil]].

The red rectangle is an NSScrollView aka @"nib". This view includes the vertical scroll bar.

The green box is an NSBox nib which is selected by NSCollectionViewItem.

How would one observe and get the scroll bar knob's position on the fly when scrolling through a list (i.e. while dragging the knob)?

Thanks for the help :)
