Namespaces¶

Namespace	Description
`nmeasim::app`	The Qt Widgets desktop application: the main window, its dock panels, the map, the instruments and the settings dialog, built on `nmeasim::io`.

File-local variables

Name	Description
`kMaxLines`	Lines kept in the view and in the buffer.
`kFlushIntervalMs`	Interval between flushes into the view, in milliseconds.

int kMaxLines{2000}

Lines kept in the view and in the buffer.

A user-interface choice that bounds the memory of the view and the cost of re-colouring it after a theme change.

int kFlushIntervalMs{150}

Interval between flushes into the view, in milliseconds.

Batching lines this way keeps the number of repaints near seven per second whatever the output rate.
