Each widget as its own set of properties, described below, that can bet modified with the set() Each widget as its own set of properties, described below, that can bet modified with the set()
method. method.
PROGRESSBAR
~~~~~~~~~~~
A progressbar widget can contain several bars, so some properties need a data section,
that means a title for the bar. For example, if you want to feed data to the `memory' bar
you want to do mywidget:set("data", "memory 100"), where memory will be the data section.
Using a new data section name will automatically create a new bar.
The following properties require a data section before the value:
*data*::
Feed with data.
*fg*::
Foreground color.
*fg_off*::
Color of unfilled area of bar.
*bg*::
Background color (between ticks; border_padding space).
*bordercolor*::
Border color.
*fg_center*::
Foreground center color.
*fg_end*::
Foreground end color.
*min_value*::
Minimum value. This or lower values, draw a 0% bar.
*max_value*::
Maximum value. This or higher values, draw a 100% bar.
*reverse*::
True to draw reverse.
The following properties do not require a data section before the value and applies to all bars inside
the widget:
*gap*::
Gap between borders.
*ticks_count*::
The number of ticks.
*ticks_gap*::
The gap between ticks.
*border_padding*::
The padding inside the border.
*border_width*::
The border width.
*width*::
The widget width.
*height*::
The widget height.
*vertical*::
If \'true\', bars are vertically aligned. If \'false\', horizontally.
GRAPH
~~~~~
A graph widget can display several data-graphs inside its widget-border. Some
properties need a data section, that means a title for the incoming data. For
example, if you want to feed \'mymemory\' data, you want to do
mywidget:set("data", "mymemory 100").
The following properties require a data section before the value:
*data*::
Feed with data.
*fg*::
Foreground color.
*fg_center*::
Foreground center color.
*fg_end*::
Foreground end color.
*vertical_gradient*::
If \'true\', colorgradient shall be applied vertically.
*max_value*::
Maximum value. Bigger values gets truncated, unless \'scale\' is true.
*scale*::
Scales the graph acccording to incoming values bigger than \'max_value\'.
*draw_style*::
\'bottom\', \'top\' or \'line\'.
The following properties do not require a data section before the value:
*width*::
The widget width.
*height*::
The widget height.
*bg*::
Background color.
*bordercolor*::
Border color.
*grow*::
\'left\' or \'right\'. E.g. \'right\' means new values get added on the right of the widget.
TAGLIST
~~~~~~~
A taglist widget displays available tags and their state.
*text_normal*::
Text to display on normal clients. \'<title/>\' substitutes the tag's title.
*text_focus*::
Text to display on the focused client. \'<title/>\' gets substituted by the tag's title.
*text_urgent*::
Text to display on urgent clients. \'<title/>\' gets substituted by the tag's title.
*show_empty*::
\'true\' or \'false\'. If \'false\', empty tags won't get displayed. Selected tags are always displayed so.
TASKLIST
~~~~~~~~
A tasklist widget displays the titles of clients according to the \'show\' setting.
*show*::
\'tags\', \'focus\' or \'all\'. E.g. \'tags\' shows only clients of currently selected tags.
*text_normal*::
Text to display on normal clients. \'<title/>\' gets substituted by the client's title.
*text_focus*::
Text to display on the focused client. \'<title/>\' gets substituted by the client's title.
*text_urgent*::
Text to display on urgent clients. \'<title/>\' gets substituted by the client's title.
*show_icons*::
\'true\' or \'false\'. Set to \'true\' if client's icon (if one is avaiable) shall be displayed.
TEXTBOX
~~~~~~~
A textbox displays text.
*width*::
Width of the widget.
*text*::
Text to display.
