Detailed Documentation

Main window of PPPLoad.

The MainWindow takes PPP stats updates from a PPPStats object, and draws a graph of the transmit and receive rates. Below the graph, the total number of bytes transmitted and received is displayed.

Public Methods Documentation

MainWindow ( QWidget* parent=???, const char* name=??? );

Create the main window.

Public Slots Documentation

void linkDown ( );

Process a link down indication.

void updateStats ( unsigned int rxDelta, unsigned int txDelta, unsigned int rxTotal, unsigned int txTotal );

Process the stats update from a PPPStats object.

Protected Methods Documentation

virtual void paintEvent ( QPaintEvent* e );

Redraw the contents of the window.

virtual void resizeEvent ( QResizeEvent* e );

Rescale the graph to fit in the new window size.
