Fluxbox is a lightweight window manager that was based on the Blackbox 0.61.1 code. It is very light on resources and easy to handle but yet full of features to make an easy, and extremely fast, desktop experience.
The software has been extended with features such as pwm-style window tabs, configurable key bindings, toolbar, and an iconbar. It also includes some cosmetic fixes over Blackbox.
Fluxbox provides configurable window decorations, a root menu to launch applications and a toolbar that shows the current workspace name, a set of application names and the current time. There is also a workspace menu to add or remove workspaces. The `slit’ can be used to dock small applications; e.g. most of the bbtools can use the slit.
Fluxbox can iconify windows to the toolbar, in addition to adding the window to the Icons submenu of the workspace menu. One click and they reappear. A double-click on the titlebar of the window will shade it; i.e. the window will disappear, and only the titlebar will remain visible.
Fluxbox uses its own graphics class to render its images on the fly. By using style files, users can configure exactly how the desktop looks. fluxbox styles are compatible with those of Blackbox 0.65 or earlier versions, so users migrating can still use their current favourite themes.
Fluxbox supports the majority of the Extended Window Manager Hints (EWMH) specification, as well as numerous other Window Hinting standards. This allows all compliant window managers to provide a common interface to standard features used by applications and desktop utilities.
This package contains support for GNOME and KDE.
