RelatedPacketDelegate::RelatedPacketDelegate

(

QWidget *

parent = 0

)

Constructs a RelatedPacketDelegate with no related frames or conversation.

Parameters

parent

Optional parent widget.

Member Function Documentation

addRelatedFrame

void RelatedPacketDelegate::addRelatedFrame ( int  frame_num, ft_framenum_type_t  framenum_type = FT_FRAMENUM_NONE  )

slot

Registers a frame as related to the current selection.

Parameters

frame_num	Frame number to mark as related.
framenum_type	Relationship type that controls which indicator is drawn (e.g. request, response, reassembly); defaults to FT_FRAMENUM_NONE.

initStyleOption()

void RelatedPacketDelegate::initStyleOption ( QStyleOptionViewItem *  option, const QModelIndex &  index  ) const

protected

Initialises the style option for a row, suppressing the default focus/selection highlight in the indicator column.

Parameters

option	Style option to populate.
index	Model index of the item being rendered.

paint()

void RelatedPacketDelegate::paint ( QPainter *  painter, const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

protected

Paints the relationship indicator for the packet at index.

Parameters

painter	Painter to draw with.
option	Style option providing geometry and state.
index	Model index of the item being painted.

setConversation()

void RelatedPacketDelegate::setConversation

(

struct conversation *

conv

)

Associates a conversation with the delegate so that conversation membership can be reflected in the rendered indicators.

Parameters

conv	Pointer to the libwireshark conversation, or nullptr to clear.

setCurrentFrame()

void RelatedPacketDelegate::setCurrentFrame

(

uint32_t

current_frame

)

Sets the frame number of the currently selected packet.

Used to determine which relationship indicators to draw relative to the selection.

Parameters

current_frame

Frame number of the selected packet.

sizeHint()

QSize RelatedPacketDelegate::sizeHint ( const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

protected

Returns the preferred size for the indicator cell.

Parameters

option	Style option providing font metrics and state.
index	Model index of the item being measured.

Returns

Recommended QSize for the indicator column cell.
