User:Mconnor/Past/Extensions2.0

This is totally a draft/work in progress/piece of junk.

We propose to add an Extensions object to the sandbox, which exposes the following:

UI

General Notes

These are objects, they have add/remove methods, take an argument that specifies a mount point (left as null, we do the right thing).

Possible example would be something like:

var menuitem = new Extensions.UI.Menuitem();
menuitem.label = "Click Me!";
menuitem.action = "doStuff()";
menuitem.add("myButton", "context-menu");

Actions

showAlert

Exposes nsIAlertsService.showAlertNotification

showAlert(aTitle, aMessage, aImage, aCallback)

showPrompt

showPrompt(title, message, button0Label, button1Label, button2Label, checkboxLabel, checked);

Description: wraps promptservice, used for all modal dialogs

• returns an array: [0/1/2, checked]
• if a label is not provided, the element is not used
• Extensions.Actions.showPrompt("Hi","Please click OK","OK");

showSidebar

Description: opens aURL in the sidebar (HTML, can be local)

showSidebar(aOpen, aURL)

Content

TBD

Prefs

Notes: this is just going to be a basic key pair array, that gets saved as JSON. No int/bool/etc nonsense, duck typing hurrah, screw prefapi and about:config, this at least is isolated and doesn't need prefbranches or about:config or anything.

savePrefs

savePrefs()

takes no args, just allows an explicit dump of prefs to disk. Prefs are automatically saved on exit.

loadPrefs

loadPrefs()

loads the saved prefs from disk, replacing the current in-memory prefs

resetPrefs

resetPrefs()

clears all prefs.

setPref

setPref(prefName, value)

Saves the value given for the given prefName

getPref

getPref(prefName, defaultValue)

Gets the stored value of prefName, returns defaultValue if no value is provided.

clearPref

clearPref(prefName)

Deletes the pref and stored value.

Storage

TBD

need to talk to sdwilsh about this. Looking to provide minimal functionality to store stuff beyond prefs, not sure we need more than one table in a DB. Seems elaborate for what is otherwise a simple API
