Demonstrate window manager functionalities
Syntax:
win-manager [-display=display_id]
[-mode=window_manager_mode]
[-verbose=verbosity_level]
Options:
- -display=display_id
-
Set the display, as an integer, to show content. If no display is provided, then
win-manageruses the default display.
- -mode=window_manager_mode
-
Set the mode in which
win-manager runs. The mode can be specified by
using one of the following strings, which are case-sensitive:
- tile
-
When running in tile mode, win-manager positions application
windows to be shown in a 4x3 grid formation on the display.
- stack
-
When running in stack mode, win-manager positions application
windows to be shown in a diagonal spread (downwards from top-left corner) on
the display.
- self
-
When running in self mode, win-manager allows
application windows to position themselves to how the application originally
created the windows. In self mode, applications can manage their own
layout-related properties.
If not specified, win-managerdefaults to running in self mode.
- -verbose=verbosity_level
-
Print information to display. You can specify the verbosity level as an integer in the range
[1..4] (default is 1). The amount of information that win-manager displays
increases from no information to maximum information as the verbosity level increases.
Description:
The win-manager binary demonstrates basic functinalities that a window manager must
support. It manages the Screen application windows that are running–
whether they were created before or after you start win-manager. The win-manager
binary is a resource manager and therefore, once running, you can send commands to it by writing the
command to its registered pathname (/dev/win-manager). These commands allow you to
interact with win-manager and control the application windows as the window manager.
The following commands are supported by
win-manager:
- bottom win-window_id
-
Move the window that's specified by window_id to the botom of the
window manager's list of windows.
- hide win-window_id
-
Make the window that's specified by window_id invisible.
- info all | win-window_id
-
Display either information on either all windows that the window manager is managing,
or only the window that's specified by window_id.
- maximize win-window_id
-
Set the window that's specified by window_id so that it's shown
as fullscreen on the display.
.
- mode window_manager_mode
-
Change win-manager to run in the mode that's specified by
window_manager_mode (e.g., tile, stack, self).
- position win-window_id x,y
-
Position the window that's specified by window_id so that its top-left
corner is at the specified coordinate on the display.
- show win-window_id
-
Make the window that's specified by window_id visible.
- size win-window_id widthxheight
-
Size the window that's specified by window_id so that its width and
height are as specified.
- top win-window_id
-
Move the window that's specified by window_id to the top of the
window manager's list of windows.
- zorder win-window_id zorder_value
-
Set the z-order of the window that's specified by window_id so that its
value is what's specified by zorder_value.
Some commands are valid only in a specific mode which win-manager is currently
running:
- tile
-
- stack
-
- bottom
- hide
- info
- mode
- show
- top
- self
-
- bottom
- hide
- info
- maximize
- mode
- position
- show
- size
- top
- zorder
To run win-manager:
- Ensure that screen is running.
-
Run win-manager from a shell.
You can start Screen applications before or after you run
win-manager. For example:
# gles2-gears
# sw-vsync
# gles1-planetary
# win-manager -mode=tile
or
# win-manager -mode=tile
# gles2-gears
# sw-vsync
# gles1-planetary
results eventually in win-manager showing the applications running in a
4x3 grid formation on the display.
-
Use the echo command to write the commands
to the pathname /dev/win-manager. For example:
# echo "hide" win-1 >/dev/win-manager
# echo "show" win-1 >/dev/win-manager
# echo "mode" stack >/dev/win-manager
Examples:
# win-manager -mode=tile
# win-manager -mode=stack
