Inheritance diagram for PinnedColumnView:

Public Slots
void	setVerticalScrollValue (int value)
	Mirrors the primary view's vertical scroll position.

Public Member Functions
	PinnedColumnView (PacketList *packet_list, QWidget *parent=nullptr)
void	setFrozenColumnCount (int column_count)
	Sets how many leftmost columns (by logical/visual index, which are kept identical in the packet list) should be shown.
void	mirrorSectionWidth (int column, int width)
	Mirrors a single section's width from the primary view's header.
void	mirrorHeaderHeight (int height)
	Forces this view's own header to the same height as the primary view's header (a plain QHeaderView's sizeHint() otherwise differs from PacketListHeader's zoom-aware one).
void	refreshLayout ()
	Forces a row-layout recompute. Must be called after this view's final geometry is set, since QTreeView computes its vertical scroll range from the viewport size at layout time; calling this before setGeometry() gives a stale (often zero) scroll range.
void	mirrorSortIndicator (int column, Qt::SortOrder order)
	Mirrors the primary view's sort indicator (the arrow icon) onto this view's own header, which is a separate QHeaderView and doesn't otherwise follow it automatically.

Protected Member Functions
void	mousePressEvent (QMouseEvent *event) override
	Forwards mouse presses to the primary packet list so that selection/marking behavior matches clicking the main view exactly.
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	leaveEvent (QEvent *event) override
void	contextMenuEvent (QContextMenuEvent *event) override
void	wheelEvent (QWheelEvent *event) override
	Forwards wheel scrolling to the primary packet list instead of scrolling this view's own (hidden) scrollbar independently, which would desync the two views' vertical positions.
void	drawRow (QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const override
	Draws the "packet separator" line under each row, mirroring PacketList::drawRow(), since gui_packet_list_separator is otherwise only ever applied by that class's own override.
void	resizeEvent (QResizeEvent *event) override
	Keeps the right-edge divider widget sized to this pane's full height whenever it's resized.

Detailed Description

A QTreeView clone showing only a leftmost run of columns from a shared model, used to keep "frozen" columns visible while the primary packet list view scrolls horizontally.

This view shares its model and selection model with the primary view so that clicking a row here selects the same row there, and reuses the primary view's item delegates so that rendering matches exactly.

Constructor & Destructor Documentation

PinnedColumnView()

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

explicit

Parameters

packet_list	The primary view this pane mirrors; passed through to its own header (see PinnedColumnHeader) since header mouse events need to be forwarded there.
parent	The parent widget (normally the same PacketList).

Member Function Documentation

mirrorSectionWidth()

void PinnedColumnView::mirrorSectionWidth	(	int	column,
		int	width )

Mirrors a single section's width from the primary view's header.

Parameters

column	The column (logical index) to mirror.
width	The new width.

setFrozenColumnCount()

void PinnedColumnView::setFrozenColumnCount

(

int

column_count

)

Sets how many leftmost columns (by logical/visual index, which are kept identical in the packet list) should be shown.

Parameters

column_count

0 hides this view entirely.

setVerticalScrollValue

void PinnedColumnView::setVerticalScrollValue ( int value )

slot

Mirrors the primary view's vertical scroll position.

Parameters

value

The new scrollbar value.
