Libwindow - a small X11-library

This is a short and probably incomplete description of Libwindow, a small library which aims to present an easy C++ interface to the X11 window system. If you want to use the library in your program, do not forget the following include directive.

#include <IFM/window>

The Window Class

• Class declaration of ifm::Wstream.

A default Window

ifm::Wstream

ifm::wio;

ifm::wio can be used whenever one default ifm::Wstream suffices. It is a so called proxy, i.e., the corresponding X-window and graphic context are created, when ifm::wio is used the first time. Consequently, if ifm::wio is not used anywhere, this creation does not happen and hence no window appears.

What can be drawn (ifm::Drawable)

Here is a list of classes/objects that can be drawn into an ifm::Wstream using the operator <<.

• Class declaration of ifm::Point.

• Class declaration of ifm::Line.

• Class declaration of ifm::Rectangle.

• Class declaration of ifm::FilledRectangle.

• Class declaration of ifm::Circle.

• Class declaration of ifm::FilledCircle.

• Class declaration of ifm::Ellipse.

• Class declaration of ifm::FilledEllipse.

• Some convenience functions.

What can be read (ifm::Getable)

Here is a list of classes/objects that can be read from an ifm::Wstream using the operator >>.

ifm::Point, ifm::Line, ifm::Rectangle, ifm::FilledRectangle, ifm::Circle, ifm::Ellipse, ifm::FilledCircle, and ifm::FilledEllipse.
