Bar - bakkeby/dusk GitHub Wiki

The built-in bar (or bars) in the window manager provides the user with information such as what workspace is being viewed, what layout is being used, titles of open windows, a systray and individual status areas as needed.

The built-in bar is highly configurable:

• the number of bars as well as their size and positions are defined on a per monitor basis
• the content of each bar is made up of bar modules that can be more or less freely placed
• most modules are subject to customisation and
• mouse click handling is supported for all modules

By default each monitor has a top bar and a bottom bar and they take up the full width of the monitor.

If you are looking to experiment with smaller separate bars then refer to the Bar Placement page which outlines how to change the size and position of the bar.

The content of the bar is controlled by individual modules that handles drawing of content and button clicks in isolation.

Refer to the Bar Modules page for more details of how the modules work should you be interested in creating custom modules.

For now it is enough to know that there are five main modules of interest:

• workspaces - shows workspace icons on the bar
• systray - positions the systray on the bar
• ltsymbol - indicates the current layout used using symbols
• flexwintitle - draws window titles on the bar
• status - shows user defined text on the bar

Additional graphics can be used to highlight different states for workspaces or window titles.

For example whether a workspace is occupied by clients or is pinned, or a small symbol indicating that a window is floating.

Refer to the Bar Indicators page for more information.

Which modules that are included on a bar and their positions are determined by the barrules setting in config.h.

Refer to the Bar Rules page for details on how this configuration works.

There are some click types that are specific to individual bar modules.

These are:

• ClkLtSymbol - clicks on the layout symbol
• ClkStatusText - clicks on status modules
• ClkWinTitle - clicks on window titles in the bar
• ClkWorkspaceBar - clicks on workspace icons

Refer to the Button Bindings page for details on general set up.
