Inheritance diagram for WlanStatisticsDialog:

Public Member Functions
	WlanStatisticsDialog (QWidget &parent, CaptureFile &cf, const char *filter)
	Constructs the WLAN Statistics dialog and registers the tap listener.
	~WlanStatisticsDialog ()
	Destroys the dialog and deregisters the tap listener.
Public Member Functions inherited from TapParameterDialog
	TapParameterDialog (QWidget &parent, CaptureFile &cf, int help_topic=0)
	Constructs the tap parameter dialog and registers it for retapping.
	~TapParameterDialog ()
	Destroys the dialog, deregisters the tap, and releases UI resources.
QTreeWidget *	statsTreeWidget ()
	Returns the statistics results tree widget for use by subclasses.
QLineEdit *	displayFilterLineEdit ()
	Returns the display filter line edit widget for use by subclasses.
QPushButton *	applyFilterButton ()
	Returns the Apply Filter button for use by subclasses.
QVBoxLayout *	verticalLayout ()
	Returns the main vertical layout for use by subclasses that need to insert additional widgets.
QHBoxLayout *	filterLayout ()
	Returns the filter bar horizontal layout for use by subclasses.
void	drawTreeItems ()
	Triggers a full redraw of all tree items, typically called after the tap has finished accumulating data.
Public Member Functions inherited from WiresharkDialog
	WiresharkDialog (QWidget &parent, CaptureFile &capture_file)
	Constructs a new WiresharkDialog object.
bool	fileClosed () const
	Checks if the capture file has been closed.
Public Member Functions inherited from GeometryStateDialog
	GeometryStateDialog (QWidget *parent, Qt::WindowFlags f=Qt::Window)
	Constructs a new GeometryStateDialog with the specified parent and window flags.
	~GeometryStateDialog ()
	Save the geometry and splitter state and then destroy the GeometryStateDialog.
void	setWindowModality (Qt::WindowModality windowModality)
	Sets the window modality for the dialog. On non-macOS platforms, this also sets the parent to ensure modal dialogs are always on top of their parent.

Protected Member Functions
void	captureFileClosing ()
	Called when the associated capture file is being closed; stops the tap and disables any actions that require live data.
Protected Member Functions inherited from TapParameterDialog
void	contextMenuEvent (QContextMenuEvent *event)
	Shows the context menu with filter and tree collapse/expand actions.
void	addFilterActions ()
	Populates the context menu with filter actions for the selected tree item.
void	addTreeCollapseAllActions ()
	Adds "Collapse All" and "Expand All" actions to the context menu.
QString	displayFilter ()
	Returns the current display filter string from the filter line edit.
void	setDisplayFilter (const QString &filter)
	Sets the display filter line edit to the given expression.
void	setHint (const QString &hint)
	Sets the hint text shown below the tree widget.
void	setRetapOnShow (bool retap)
	Controls whether packets are retapped when the dialog is first shown. RPC statistics dialogs should disable this to manage their own retap timing.
Protected Member Functions inherited from WiresharkDialog
virtual void	keyPressEvent (QKeyEvent *event)
	Handles key press events.
virtual void	accept ()
	Accepts the dialog.
virtual void	reject ()
	Rejects the dialog.
virtual void	beginRetapPackets ()
	Mark the start of a code block that retaps packets. If the user closes the dialog while tapping, the dialog will not be destroyed until endRetapPackets is called.
virtual void	endRetapPackets ()
	Mark the end of a code block that retaps packets. If the user has closed the dialog it will be destroyed at this point.
void	setWindowSubtitle (const QString &subtitle)
	Set the window subtitle, e.g. "Foo Timeouts". The subtitle and file name will be added to the dialog window title.
const QString &	windowSubtitle ()
	Retrieves the current window subtitle.
virtual void	updateWidgets ()
	Updates the state and contents of the dialog's widgets.
bool	registerTapListener (const char *tap_name, void *tap_data, const char *filter, unsigned flags, tap_reset_cb tap_reset, tap_packet_cb tap_packet, tap_draw_cb tap_draw)
	Convenience wrapper for register_tap_listener. Tap listeners registered via this function are automatically removed during destruction. They can also be explicitly removed using remove_tap_listener or removeTapListeners.
virtual void	removeTapListeners ()
	Remove all tap listeners registered via registerTapListener.
bool	dialogClosed () const
	Check to see if the user has closed (and not minimized) the dialog.
int	retapDepth () const
	Check to see if we're currently retapping. If this is positive, tapping will fail in process_specified_records.
virtual void	captureFileClosed ()
	Called when the capture file was closed. This can be used to enable or disable widgets according to the state of file_closed_. updateWidgets() is called at the end.
Protected Member Functions inherited from GeometryStateDialog
void	loadGeometry (int width=0, int height=0, const QString &dialog_name=QString())
	Loads the geometry and splitter state for the dialog.
void	loadSplitterState (QSplitter *splitter=nullptr)
	Loads the state of a splitter for the dialog.

Additional Inherited Members

void	updateFilter (QString filter)
	Emitted to push a new display filter to the main window filter bar.
Static Public Member Functions inherited from TapParameterDialog
