Subject: RE: [Dynapi-Dev] Widgit creation - Tab and Focus


related to the management of keystrokes, focus and blur events in events.js
----------------------------------------------------------------------------

My idea is less complicated (i think) and requires fewer code. Instead of
creating a more complex object that manages a list of widgets and bubbles
the focus events, just leave the browser window take care of it.

Here is an example using dhtm (not dynapi) IMPORTANT: it works only in ie 5
(i not warrant that this html will look fine in other browser, but maybe ie
5.5 or 4.x):

see attached file.
------------------

what im doing right now with dynapi is something like this:

1) saving the original DynLayer createElement in a separated pointer
   (inherited_createElement) on my widget.
2) overwriting this createElement method
	2.1) in this overwrote method i call the inherited_createElement
	2.2) after that, i add the anchor tag using insertAdjacentHTML method

3) i think thats it!

Everybody requiring this functionality just will need to base their own
widgets on this one and Presto!, we have widgets that can take focus not
just by clicking but using the tab key also.

However we need to review events.js and add the capability to manage focus,
blur and keydown events so we can do everything just using common
eventListeners, im still having problems there because it stills working
only in ie. But i hope that somebody more familiar to ns will solve these
problems someday... What i need for now is get this thing working on IE
under a Win environment a soon as posible: A widget that copies the behavior
of a TStringGrid (developers familiar with Delphi will know whats that) and
time is almost over!

cheers guys!

Subject: [Dynapi-Dev] Widgit creation - Tab and Focus



Heya guys,

Scott and I had a brief thread going last spring about having the concept of
"focus" shared amongst many widgits on the same page.
This is to facilitate "tabbing" between controls and the blinking of
"carets" for edits, etc...

One thought was to have a global constructor that each widgit would
"register" with.  The Dynapi would keep a list of the widgits in the order
they were created, this then becomes the "tab order".  Assuming we can
successfully trap the tab key in both browsers, the dynapi would catch it
first before bubbling it to the widgets.  It would then send an OnBlur()
event to whichever control currently had focus and an OnFocus() event to the
next in the list.

Any thoughts on if this could be acheived?  Anyone else see the need for it?

Also, how about a "standard" construction call for widgit builders to use?
Something like create(x,y,w,h,fgcolor,bgcolor,skin)

And maybe a set of standard events.
refresh() comes to mind.


-cheers!
