InlineEditBox: need to cancel or save onblur (if autoSave=true)

[haysmark]

In the topmost inline textbox in test_InlineEditBox, if you click the text to edit there is no way to cancel the edit; the textbox "sticks" on blur unless/until you change the value to something else, after which it behaves as expected.

Clicking outside the edit widget or it's dropdown (an effective onBlur *on the widget*) should cause the current changes to save, or if no changes were made, should cause a cancel.

(But see related bug #3655 about canceling via the keyboard)

In any case should be able to cancel by hitting the ESC key (and of course if autoSave=false there's a cancel button). It's the same as changing a filename in Windows Explorer.

Hmm, but apparently the ESC key isn't working right now. I think that's in Peter's patch?

[bill]

I split this bug up into keyboard support (#3655) and general clicking support (this bug).

Basically what we need is onBlur and onFocus events on widgets, rather than on dom nodes. Shifting focus from one dom node to another node inside the same widget, or even switching from the widget to the dropdown (and back again), shouldn't cause such an onBlur event, because conceptually you are still inside the widget.

[bill]

(In [9561]) Implement onFocus and onBlur at a widget level. Clicking different dom nodes within a widget, or even switching between a ComboButton? and it's drop down menu, will not cause an onBlur event on the Combobutton. The onBlur only happens when focus moves completely away from the widget.

Focus is not quite the right word because it keeps track of a stack of widgets that are all active. Example: Combobutton --> Menu --> MenuItem?.

Needs more testing but seems to be working.

Fixes #3648.

[bill]

(In [9576]) add gratuitous animations to test (refs #3648)

[bill]

(In [9599]) For IE, don't publish "focus" events for when user clicks on a blank area of the screen or a non-focusable elements, causing focus to disappear completely.

Refs #3648.

(In [9600]) Better inline doc. Refs #3648.

[bill]

(In [9631]) improve testcase (refs #3648)

[bill]

(In [9636]) Bunch of fixes for keyboard support in InlineEditBox?.

Fixes #3482: missing focus events when using InlineEditBox? Accessibility Fixes #3648: Regression in [9508]: no cancelling if autoSave=true (added support for the Esc key.) Fixes #3655: Open inline edit box, don't make change, tab out, edit box stays open Fixes #3674: pressing tab on an open autosave widget should move focus to next widget

Patch from Pete Brunet (IBM, CCLA on file)

[bill]

(In [9637]) Prevent strange error about "]". Removed the onClick(/*Event*/ evt) callback. (If we need a callback when editing is started should probably be called something different, and doesn't need to be passed the event object.) Refs #3482, #3648, #3655, and #3674.
