Detailed Description

QHeaderView subclass that adapts its size based on the font.

This class ensures that the header height is updated when the font changes, providing a consistent appearance even when the font is zoomable.

The font is still set through the parent (PacketList in the case of the packet list header), so that it is shared with the rest of the UI. This class simply ensures that the header height is updated when the font changes, by overriding sizeHint and responding to font change events.

We could instead register directly with FontManager and update the size hint when the font changes, but that would require a bigger redesign.

Constructor & Destructor Documentation

AdaptiveHeaderView()

AdaptiveHeaderView::AdaptiveHeaderView	(	Qt::Orientation	orientation,
		QWidget *	parent = nullptr )

Constructs an AdaptiveHeaderView.

Parameters

orientation	The orientation of the header.
parent	The parent widget.

Member Function Documentation

sizeHint()

QSize AdaptiveHeaderView::sizeHint ( ) const

overridevirtual

Overriding sizeHint to provide proper heights when font changes.

Starting with 5.x the regular font is zoomable and therefore the header can change its height. This override ensures that the header height is updated when the font changes.

Returns

QSize the size of the header view
