Queen BeeCon Widget





Queen BeeCon Widget (See Talk Thread) is a highly customizable and flexible widget-based multi-instance monitoring, alerting and interactive tool for Maemo 5 Fremantle and the N900.

The Widget is based on the execution of external Shell/OS Commands which can be either as simple as one-liner statements or as complex as articulated shell scripts, which, for example, fetch, parse and aggregate contents retreived from the system, other applications or the Internet.

There are two basic Widget types, Beecons and Snippets:

Beecons are small hexagonal cells whose background color or associated image/icon changes according to the executed Command Exit Status.

Beecons can handle virtually unlimited Command Exit Status:


 * <0 Normally notifying system errors in esecuting the script/command
 * 0 Returned when script/command successfully completes
 * 1 Used to report a warning condition
 * 2 If script/command needs to notify some application error conditions
 * <=126 Other exit status which can be handled for displaying user defined icons/images

Snippets are normal text/graphic boxes with fixed background color and images which is not influenced by the executed Command Exit Status.

Current Status in Maemo Repositories
(v0.1.4 extras-devel / v0.1.4 extras-testing)

= Features List =


 * Widget can be multi-instantiated, disabled and minimized on desktop (click on minimized icon on desktop will wakeup and maximize instance)
 * Possibility to define multiple commands and command labels to be displayed inside the Widget
 * Different types of Widget layouts and behaviours (currently Beecons and Snippets)
 * Possibility to hide the background Canvas both for Beecons and Snippets
 * Possibility to use icons/images instead of text both for Beecons/Snippets command title and output (with high positioning, zooming/scaling 5%-200%-FitToWidget versatility) ;)
 * It is possible to indipendently show or hide both snippet's images/texts and beecon images/texts . This way you can have two images and two text placeholders on widget, for more flexibility in graphic layout
 * Independent images/icons for Command Exit Statuses >=3 can also been specified. The display of this extended statuses is driven by Command Exit Status . Useful, for example, for displaying different icons according to percentages values returned by command.
 * Possibility to use different icons/images for Beecon's status output instead of just specific background color (Ex. 0=green led, 1=yellow led, 2=red led) (with high positioning versatility) ;)
 * Nice gummy "button-press"-like visual feedback using Gradient fill
 * Widget relies also on a private general purpose directories "~/.queen_beecon_dir/" & "..../MyDocs/.images/queen_beecon_dir/" as images/icons/etc. immediate storage. For easier population via USB of BLUETOOTH File Services.
 * Widget texts can be formatted through Pango Markup Language
 * Widget Size can be customized (Width: 10-800, Height: 10-420) and position can be fine tuned (X,Y +/- 5pix); Tweaking /usr/share/hildon-desktop/transitions.ini may also help. (snap_grid_size = 1 & snap_to_grid_while_move = 1)
 * Background color for Beecons can be customized for each 4 Command Exit Statuses
 * Background color for Snippets can be customized
 * Font Color of both command label and results can be configured
 * Position and Visibility of both command label and results can be configured (Hidden, Top L, Top C, Top R, Center L, Center, Center R, Bottom L, Bottom C, Bottom R)
 * Font Face of both command label and results can be configured (Nokia Sans, NewCourier, NewTimes, Monospace, Nokia Sans Cn, Nokia Sans Maps, Nokia Sans SemiBold, Sans, Serif, SwissA, Tanseek Pro Arabic, Univers OTS Arabic)
 * Font Style of both command label and results can be configured (Regular, Italic, Bold, Italic Bold)
 * Text Justification of both command label and results can be configured (Left, Center, Right, Fill)
 * Font Size of both command label and results can be configured (8->48)
 * Command execution can be triggered optionally on widget startup, by manual pressing on Widget, by desktop switching , by periodic updates (0=Manual, 30s, 1m, 5m, 30m, 1h, 6h, 12h, 1d)
 * Command execution can be subject to network connection status.
 * Tool includes a powerful Advanced Maintenance Dialog Box for command development and testing (TestDrive mode to display raw output of predefined or user-defined commands)
 * Advanced Maintenance Dialog Box includes extended functionalities like: instance export/import w/ checksum, command export/import w/ checksum, command update with current Test Drive buffer, clipboard operations.
 * A set of basic Images/Icons for Snippets and Beecon Statuses is included inside the distribution package and installed inside canonical hildon hicolor 48x48 directory
 * For Web and Proxy related issue please have a look to THIS post.

= HOW-TOs =

Create a new Basic Instance of QBW
After you have installed QBW package, these are the steps to create and start customizing a new Instance of the widget.


 * Tap on an empty area of the Desktop and gear icon for configuration will pop up in the upper right area of the screen
 * [[Image:Qbwinst1.png]]


 * Click on the "Add widget" button
 * [[Image:Qbwinst2.png]]


 * Scroll selector till you find "Queen Beecon Widget" and click on it
 * [[Image:Qbwinst3.png]]


 * A new instance of the widget will be created with very basic default configuration
 * [[Image:Qbwinst4.png]]


 * Now if you click on the Settings Wrench Icon you'll reach the [B]Settins Dialog[/B] for customization

How and Where to store Icons and Images for your Beecons
If no PATH is specified in the Settings for Icons & Images, QBW will look in directories on the phone's internal memories in the following order:


 * First, the directory accessible via Bluetooth/PC Suite/OVI Suite or USB (Storage Mode).

/home/user/MyDocs/.images/queen_beecon_dir/


 * [[Image:Qbwwtsi.png]]


 * WARNING!!! When phone is connected via USB in Storage Mode this directory is not available to the Widget; so if you plan to use QBW when in Storage Mode use directory in "Second" point.

/home/user/.queen_beecon_dir
 * Second, the directory:

/usr/share/icons/hicolor/48x48/hildon/
 * Third, the directory where QBW's Package Icons are stored:

If you want to replace a partial/complete set of QBW's Package Icons just create Icons/Images with same name in directories "First" or "Second"

If specified image is not found, following icon will appear:



Backup all Widget Instances
Apply Export/Save/Backup Procedure for Beecon Instance Data for every Widget Instance you want to Backup

Save content (Beecons' Images) of directories: /home/user/.queen_beecon_dir /home/user/MyDocs/.images/queen_beecon_dir/

Restore all Widget Instances
Apply Import/Load/Restore Procedure for Beecon Exported Instance Data for every Widget Instance you want to Restore

Restore content (Beecons' Images) of directories: /home/user/.queen_beecon_dir /home/user/MyDocs/.images/queen_beecon_dir/

Import/Load/Restore Procedure for Beecon Exported Instance Data
See HERE

Export/Save/Backup Procedure for Beecon Instance Data
See HERE

Copy Exported Instance Data from Browser to Phone's Clipboard
See HERE

Reset QBW to Default Configuration/Commands
sudo gainroot (only if you are not already root) rm /home/user/.queen_beecon killall hildon-home
 * Open up X-Terminal (or SSH/Putty into N900) and issue the following command

Completely remove QBW from your N900
sudo gainroot (only if you are not already root) dpkg -P queen-beecon rm /home/user/.queen_beecon rm -r /home/user/.queen_beecon_dir rm -r /home/user/MyDocs/.images/queen_beecon_dir/
 * Open up X-Terminal (or SSH/Putty into N900) and issue the following command

= Easter Eggs =

Magic Word for bypassing Export/Import Instance Data CheckSum protection


'''Use the Source ... Luke! ;)''' or ask politely!!!

= Troubleshooting =

Startup
If you are having issues at widget startup because of improper "Update on Widget/System Startup" settings:

sudo gainroot (only if you are not already root) vi /home/user/.queen_beecon
 * Open up X-Terminal (or SSH/Putty into N900) and issue the following commands:


 * find updOnStartup=true (all instances supposed to be culprits)


 * Set it to false (updOnStartup=false)


 * Save file

killall hildon-home
 * Immediately issue:


 * hildon-home will automatically restart and widgets won't run any more at startup

"No Output" is displayed inside Widget instead of expected output
If you are using Pango Markup Language Tags as output from your scripts, make sure all Tags are correctly written/spelled and terminated.
