Before you use any configuration menu stuff, you NEED to add a new callback to your script: def menuOptionChanged(widget, key, value): This will get called whenever a config menu option is changed. Now you can add items to the config menu: addMenuConfigOption(widget, String key, String name) Key is the name of a key value where the value will be saved automatically into the widget's config file. Name is the actual text that will show up in the config menu. For example, I could allow the user to enable or disable a clock showing up in my theme: karamba.addMenuConfigOption(widget, "showclock", "Display a clock")

Misc

acceptDrops

Calling this enables your widget to receive Drop events. In other words, the user will be able to drag icons from his/her desktop and drop them on your widget. The "itemDropped" callback is called as a result with the data about the icon that was dropped on your widget. This allows, for example, icon bars where items are added to the icon bar by Drag and Drop.

Synopsis:
boolean acceptDrops(widget)

Arguments:

• reference to widget -- karamba

Return Value:
true if successful

attachClickArea

It is possible to attach a clickarea to a meter (image or text field), which is moved and resized correctly if the meter is moved or resized. There is also a callback meterClicked(widget, meter, button) which is called whenever a meter is clicked (if something is attached to it). Given an Image or a TextLabel, this call makes it clickable. When a mouse click is detected, the callback meterClicked is called. lB, mB, and rB are strings that specify what command is executed when this meter is clicked with the left mouse button, middle mouse button, and right mouse button respectively. If given, the appropriate command is executed when the mouse click is received. The keyword arguments are all optional. If command is an empty string nothing is executed. For now the command given to RightButton has obviosly no effect (because that brings up the SuperKaramba menu).

Synopsis:
boolean attachClickArea(widget, meter, lB, mB, rB)

Arguments:

• reference to widget -- karamba
• reference to meter -- meter
• string lB -- command to left mouse button
• string mB -- command to middle mouse button
• string rB -- command to right mouse button

Return Value:
true if successful

callTheme

Calls a theme - identified by the pretty name - and passes it a string to it. This will work, despite superkaramba being multithreaded, because it uses the DBus interface to contact the other theme. If you need to pass complex arguments (dictionaries, lists etc.) then use the python "repr" and "eval" functions to marshall and unmarshall the data structure.

Synopsis:
boolean callTheme(widget, theme, info)

Arguments:

• reference to widget -- karamba
• string theme -- pretty theme name
• string info -- a string containing the info to be passed to the theme

Return Value:
true if successful

For more information on the difference between createClickArea() and createServiceClickArea, see the KDE documentation about KService, and the difference between KRun::run() and KRun::runCommand.

Synopsis:
reference createServiceClickArea(widget, x, y, w, h, name_of_command, cmd_to_run, icon_to_display)

Arguments:

• reference to widget -- karamba
• integer x -- x coordinate
• integer y -- y coordinate
• integer w -- width
• integer h -- height
• string name_of_command -- name to be displayed
• string cmd_to_run -- command to be run()
• string icon_to_display -- name of icon to be displayed

Return Value:
reference to the new click area

This command simply executes a program or command on the system. This is just for convience (IE you could accomplish this directly through python, but sometimes threading problems crop up that way). The only option is a string containing the command to execute.

Synopsis:
integer execute(command)

Arguments:

• string command -- command to execute

Return Value:
process id of the executed command

executeInteractive

This command executes a program or command on the system. Additionally it allows you to get any text that the program outputs. Futhermore, it won't freeze up your widget while the command executes. To use it, call executeInteractive with the reference to your widget and a list of command options. The array is simply a list that contains the command as the first entry, and each option as a separate list entry. Output from the command is returned via the commandOutput callback. The command returns the process number of the command. This is useful if you want to run() more than one program at a time. The number will allow you to figure out which program is outputting in the commandOutput callback. Example: Run the command "ls -la *.zip" myCommand = ["ls", "-la", "*.zip"] karamba.executeInteractive(widget, myCommand)

Synopsis:
integer executeInteractive(widget, command)

Arguments:

• reference to widget -- karamba
• list command -- command to execute()

Synopsis:
string getPrettyName(theme)

Arguments:

• string theme -- path to new theme

Return Value:
the pretty name of the theme

getServiceGroups

This function returns a list of services and service groups that are in the user's KDE Menu. It is not a recursive function, so if there are submenus (service groups) in the returned results, you must call getServiceGroups with the path of the submenu in order to obtain the information in that submenu. The return result is complex: it's a list of tuples. The tuple contains two elements - a 1 if the second element is a service, and a 0 if it's a service group. The second element is a dictionary, with keys (if they exist) of caption, comment, icon, and relpath if it's a service group, and keys (if they exist) of exec, menuid, name, path, icon, library, comment, type and genericname. To fully understand the return results of this function, it is thoroughly recommended that you look up the KDE documentation on KServiceGroup and KService.

Arguments:

• reference to widget -- karamba

Return Value:
true if successful

openNamedTheme

Opens a new theme, giving it a pretty (alternative and by your own choice _unique_) name. If you do not want the theme to be loaded when SuperKaramba is first started up (but instead want it to only be opened by this function call) then set is_sub_theme to 1. Themes opened with openNamedTheme will be unique. If a theme with the same pretty name already exists, openNamedTheme will have no effect. If you want duplicate themes (and a bit of a mess), use openTheme(), instead.

Synopsis:
reference openNamedTheme(theme, pretty_name, is_sub_theme)

Arguments:

• string name -- name to be displayed
• string command -- command to execute()
• string icon -- name of icon to be displayed
• string list_of_args -- arguments to be passed to the command

Return Value:

The difference between setIncomingData and callTheme() is that the theme is not notified by setIncomingData that the data has arrived. Previous information, if any, is overwritten. Use getIncomingData() to retrieve the last stored information. setIncomingData is not very sophisticated, and could benefit from having info passed to it put into a queue, instead of being overwritten.

Synopsis:
boolean setIncomingData(widget, theme, info)

Arguments:

Wiki Markup Generation

To generate this API documentation execute the make_api_doc.sh script from the SuperKaramba docs dir.

./make_api_doc.sh rtf

This will generate a rtf file named superkaramba_api.rtf. Open the file in a word processor e.g. OpenOffice and save the file as plain text.

The next step is to modify the file contents to match the necessary wiki markups. This can be done with the following command.

cat sk_plain_api | sed -e "/DESCRIPTION/d;/^[ ]*$/d;s/^*//;s/SYNOPSIS/<br><br>'''Synopsis:'''<br>/;s/ARGUMENTS/<br><br>'''Arguments:'''<br>/;s/RETURN VALUE/<br>'''Return Value:'''<br>/;/\//{s/^/\r\n=== /};/\//{s/$/===/};s/robo[0-9]\{1,\}//g" > SK-API

The contents of SK-API file can now be copied into the edit window of the wiki page.

Tip

It is recommended to port the changes of this document to the KarambaInterface class to ensure a coherent API document in future.
