Apple NSScrollView tile contentView bounds scroller style legacy official documentation
💡 Result:
In AppKit, the NSScrollView class uses the tile method to manage the layout of its internal components, including the content view (NSClipView), scrollers, and ruler views [1][2][3]. Key technical details regarding these components and their interaction include: 1. The tile Method: This method is responsible for laying out the scroll view's components [1][2]. While developers rarely need to invoke it directly, subclasses may override it if they need to manage custom components or specific layout adjustments [2][3]. 2. Content View (NSClipView): The content view is the NSClipView instance that clips the document view [1][4]. The scroll view manages the position of the document view by modifying the bounds rectangle of this content view [4][5]. Programmatic changes or layout updates to the scroll view, such as switching scroller styles, typically trigger an automatic re-tiling [6]. 3. Scroller Style (Legacy vs. Overlay): The scrollerStyle property determines the appearance and behavior of the scroll bars [1][6]. - NSScroller.Style.legacy: Represents the traditional scroller style available prior to macOS 10.7, where scrollers often occupy fixed space within the scroll view's frame [7][8]. - NSScroller.Style.overlay: The modern default, where scrollers may overlay the content [7][8]. - When the system-wide scroller style preference changes, AppKit automatically updates the scrollerStyle of existing NSScrollView instances, which subsequently triggers the tile process to adapt the layout [6]. 4. Calculating Frame and Content Sizes: When performing manual layout calculations, you should avoid older, deprecated methods that make assumptions about specific scroller classes or styles [9]. Instead, use modern equivalents that accept parameters such as scrollerClass, controlSize, and scrollerStyle to ensure accurate frame and content size calculations [1][9].

Size terminal content from the tiled clip view.
scrollView.bounds describes the outer NSScrollView. scrollView.contentView.bounds describes the clipped viewport. The current method reads the outer bounds before the later tiling and uses that width for surfaceView and documentView. With legacy scrollers, the terminal grid can extend into the scroller gutter.
Tile and lay out scrollView before calculating these frames. Use scrollView.contentView.bounds.size and scrollView.contentView.bounds.width. Remove the later redundant tiling and layout block.
