Protected Member Functions
void	updateGeometries () override
	Widens this view's horizontal scroll range to the primary view's. QTreeView derives the range from its own content and viewport widths, which differ from the primary view's (frozen columns hidden here, scrollbar width), so at the far right edge this view would otherwise clamp short and stop scrolling while the primary view keeps going, misaligning the pinned rows' columns.
void	mousePressEvent (QMouseEvent *event) override
	Selects the clicked pinned row in this view's own selection model (linked to the primary packet list's by PacketList), marks it on a middle click, and arms a cell drag.
void	mouseReleaseEvent (QMouseEvent *event) override
void	mouseMoveEvent (QMouseEvent *event) override
	Reports the row under the mouse to the primary packet list so the hover highlight can be shown across every pane, not just this one.

void	drawRow (QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const override
	Draws the hover highlight (which spans every pane) and the "packet separator" line, mirroring PacketList::drawRow().

	Keeps the "corner" boundary-divider widget sized to this view's full height whenever it's resized.

Detailed Description

A QTreeView clone that shows every row of a PinnedRowsModel (i.e. every currently pinned packet, packed together with no gaps), used to keep pinned packets visible while the primary packet list view scrolls.

The same class also serves as the "corner" widget when rows are pinned at the same time as columns are frozen, by restricting the rendered columns via setColumnRange().

Constructor & Destructor Documentation

◆ PinnedRowView()

PinnedRowView::PinnedRowView	(	PacketList *	packet_list,
		QWidget *	parent = nullptr )

explicit

Constructs a PinnedRowView.

Parameters

packet_list	The primary PacketList this view mirrors rows for and forwards mouse/context/wheel events to. Kept as an explicit pointer (rather than assuming parentWidget() is the PacketList, which no longer holds now that this widget lives inside PacketListPane's layout alongside, not inside, PacketList).
parent	The parent widget.

Member Function Documentation

◆ isCornerView()

bool PinnedRowView::isCornerView ( ) const

inline

Whether this instance is currently acting as the "corner" widget (the frozen-column portion of the pinned-row strip, shown alongside PinnedColumnView's own frozen-column overlay) rather than the main pinned-row strip covering the remaining columns.

Both first_column_ == 0 and last_column_ >= 0 are required: the main pinned-row strip's own range is set to (pinned_column_boundary_, -1), which also starts at column 0 whenever no columns are currently frozen (pinned_column_boundary_ == 0) – first_column_ == 0 alone (what right_divider_'s own visibility already checks, harmlessly there since the corner instance is simply hidden whenever that ambiguity would matter) can't distinguish that case from the corner's own range, which is always a bounded [0, boundary - 1] and so never has last_column_ == -1.

Used by MultiColorPacketDelegate to paint this instance the same flat-fill way as PinnedColumnView – unlike the main pinned-row strip, which follows the primary view's real stripe/shift-right pattern – since the corner only ever shows a narrow, frozen slice of the row, same as PinnedColumnView.

◆ setColumnRange()

void PinnedRowView::setColumnRange	(	int	first,
		int	last )

Restricts which columns this view renders.

Parameters

first	First column (logical index, inclusive) to show.
last	Last column (logical index, inclusive) to show, or -1 for "through the last column".
