pfUIScrollFrameTemplate (api/ui-widgets.xml) is a ScrollFrame with
pfUIScrollBarTemplate inside its right edge and a Content scroll child,
driven by ScrollUtil.InitScrollFrameWithScrollBar. The panels keep a
ScrollFrame because the engine measures its range from the shown frames
inside the content, which the hand-placed config rows rely on. The bar
follows OnScrollRangeChanged instead of an OnUpdate poll per panel.
A panel measures its range once its rows are built, and the search
results measure theirs with UpdateScrollChildRect instead of hiding,
re-attaching and scrolling a frame later. Clearing the search measures
again too.
CreateScrollFrame and CreateScrollChild have no users left, and nothing
called CreateTabFrame or CreateTabChild; all four are gone. pfQuest's
compat layer brings its own copies of the scroll helpers.
pfUIScrollBoxListTemplate (api/ui-widgets.xml) is a WowScrollBoxList with
pfUIScrollBarTemplate beside it, 5px inside the frame, so a list's
backdrop goes on the frame itself. The addon list moves onto it and drops
the sibling backdrop frame.
Loot history builds a flat list of item rows and, under an expanded item,
player rows; the view sizes and indents them. The item frame array, the
player pool, the hand-placed rows and the scroll child re-attach are gone,
and the scroll position holds across roll updates.
The icon picker's FauxScrollFrame and 80 fixed buttons become a grid view
over the provider's icon indices. Picking an icon reinitializes the shown
buttons instead of redrawing the grid, and closing the popup drops the
grid's entries along with the provider.
pfUIScrollingEditBoxTemplate (api/ui-widgets.xml) is ScrollingEditBoxTemplate
with pfUIScrollBarTemplate beside the text. Its mixin's SetFont gives the
box a font object of its own, since the edit box sets its font by object on
every SetText and pfUI fonts are paths. ui-widgets.lua now loads before the
XML, which needs the mixin.
The share box no longer recomputes its scroll child on every text change.
Chat copy reads each chat frame's messages with ClassicAPI's
GetMessageInfo when it opens, so the AddMessage hook, its 100-line copy of
the history and the skip of combat frames are gone. It shows every line
the frame keeps, lines from before login included. It puts the caret at
the end to scroll to the newest line instead of three OnUpdate passes, and
Escape now leaves copy mode on every chat frame.
The list built one row per addon in a ScrollFrame, hid the rows out of
view by hand and drove pfUI's own slider. A WowScrollBoxList keeps rows
only for the addons in view and recycles them while scrolling.
pfUIScrollBarTemplate (api/ui-widgets.xml) is a ScrollBarMixin bar with
the old slider's look: a thin track and a flat teal thumb that hides when
nothing scrolls. Its steppers exist for the mixin but stay hidden.
Rows read the addon's enabled state, so profiles enable and disable
addons directly instead of clicking every row's checkbox. A checkbox
now shows whether an addon is enabled; it showed whether it was loaded.
