ContextHelp - Vaadin Add-on Directory

Provides contextual help for Vaadin applications.

ContextHelp is a component allowing you to provide contextual help for your forms and/or fields in an application. ContextHelp shows a bubble containing your specified help text when the user presses F1 (or a configurable hotkey). The bubble opens right next to your field, with a small arrow pointing at the field. ContextHelp also supports opening the help bubble programmatically and follow focus.

ContextHelp version 0.0.4
The only changes in this version is in the packaging of the add-on.

ContextHelp version 0.8
Bugs fixed include the elusive internal NPE when changing "follow focus" state. This version can be considered feature complete (for 1.0) and reasonably stable, but I will keep it in beta for a while in case new bugs are found.

ContextHelp version 1.0
- It's now possible to define which key opens the help bubbles - The help bubble can be positioned above/below or to the right or left of fields on a per-field basis - And bugfixes of course

ContextHelp version 1.1.0
- You can now provide your own help text provider for retrieving help texts based on the components debug id. - Unload handling fixed, so you can now add and remove the component at will without causing errors. - Small UI tweaks.

ContextHelp version 1.2.0
- Added the HelpFieldWrapper class to easily add a help icon beside fields in forms. Just wrap the fields in the HelpFieldWrapper in your field factory.

ContextHelp version 1.2.1
- Fixed a bug where the help text might be rendered before the component to show it for, causing an exception and crashing the rendering. - Made DefaultHelpProvider serializable

ContextHelp version 1.3.0
- Added fully programmatic control. - setStyleName now works correctly - Added setter/getter for the help provider

ContextHelp version 1.3.1
- The help bubble is no longer closed if you click within the component it is bound to or in the bubble itself. This allows you to copy text from the bubble, keep a general help bubble open while navigating fields in a form, etc. - Added a null check to fix issue #11

ContextHelp version 2.0.0.beta1
ContextHelp is now compatible with Vaadin 7 and is now a UI extension. See the demo sourcecode on github for an example.

ContextHelp version 2.0.1
