1.1 Qwt

Warning: The documentation is for the future PyQwt-4.2.3 which is only available from CVS. The download page has links for the latest releases.

Qwt is a C++ library based on the Qt GUI framework from Troll Tech AS. The Qwt library contains widgets and components useful to write technical, scientific, and financial programs. It includes the following widgets:

QwtCompass: a very fancy QDial-like widget to display and control a direction.
QwtCounter: a QSpinBox-like widget to display and control a bounded floating point value.
QwtDial: a QDial-like widget to display and control a floating point value.
QwtKnob: a potentiometer-like widget to display and control a bounded floating point value.
QwtPlot: a widget to plot two-dimensional data points.
QwtSlider: a QSlider-like widget to display and control a bounded floating point value.
QwtThermo: a thermometer-like widget to display a floating point value.
QwtWheel: a wheel-like widget with its axis parallel to the computer screen to control a floating point value over a very large range in very small steps.

The widgets are documented in the Qwt manual on your hard disk or Qwt on the web.

Note: The designer plug-in for Qt-3.x.x of the Qwt library works with PyQwt. If you did built PyQwt against its slightly patched internal version of Qwt, you must install either the original or the internal Qwt library.
