Re: [Dynapi-Help] What is enableBlackboard?

[<do...@cr...>]

More verbose.. also checked code to verfiy.. the part about a transparent
coverlayer was just smoke (won't say what kind of smoke..)

So.. 

As we know, if you add a child layer or widget to a layer, then set the html
of that layer, the existing html (the child ler or widget) get's deleted.
Obviously this can cause some issues if your coed expects said layer or widget
to be there.

The solution to this is to call enabledBlackBoard on the parent layer.
Having done this, when you call setHTML() on a layer that has it's Blackboard
enabled, the html that you specify is placed within the blackboard instead of
replacing the html of your parent layer.

Man reading the above just confuses me.. and i wrote it :-)
new visual:

case 1 (no blackboard)
create a layer and add a widget:
(result)
[myLayer]
    [myWidget][/myWidget]
[/myLayer]

then call myLayer.setHTML("where's the widget?")
(result: note the widget is gone)
[myLayer]
    Where's the widget?
[/myLayer]

case 2 (with blackboard)
create a layer, add a widget, enable blackboard
[myLayer]
    [myWidget][/myWidget]
    [_blkBoardElm][/_blkBoardElm]
[/myLayer]
then call myLayer.setHTML("there's the widget!")
[myLayer]
    [myWidget][/myWidget]
    [_blkBoardElm]there's the widget![/_blkBoardElm]
[/myLayer]

One thing i do notice while looking at the code is that we do not specifiy the
Z-Order of the blackboard. This can cause a problem if the blackboard is added
after a widget or childlayer has been added as the blackboard may overlap said
child layers.

notes:
if blackboard is enabled after a sethtml call (or layer is created with
default html in the new dynlayer() call) then the html will be transferred to
the blackboard.

Recommend specifying a largely negative Z-Order on the blackboard layer

Cheers

Re: [Dynapi-Help] What is enableBlackboard?

[<do...@cr...>]

The wierdest things pop into your head when walking to work..

here it is.. the blackboard as described below is to allow you to add a child
layer to a layer, and then later call sethtml on the parent layer without
accidently deleting the child layers :-)

Glad we got that sorted out. :-P

I tried various combinations of addChild and insert to no avail.  The 
outermost layer gets positioned incorrectly.  I'll have to try the 
inline feature.  But I'd really like to understand the problem.  I don't 
think it's doing anything that shouldn't be possible with a fully 
dynamic layer.  Maybe it's a usage thing.  But as I'm still learning the 
API, I can't spot it off hand.

Using Firefox, I saw only one instance of the DIV.  I'm wondering 
perhaps if adding the child and inserting it messes with the box model 
stuff.  I seemed to get a few pixels difference (from 7-20), which might 
be some CSS border widths of DIV and IMG tags.

Well, yeah.  But without any further input from the user, I can only 
guess by the erroneous behaviour I see in my test code based upon the 
user's initial incomplete example.

Please note that I did create a bug entry for this so that I would not 
forget.

[ 1257263 ] Events send wrong X/Y coords to relative layers.

Re: [Dynapi-Help] What is enableBlackboard?

[<do...@cr...>]

I haven't actually looked at the code yet but i do believe that
enableBlackboard creates two child layers in your layer, one which covers the
content and is transparent, and one which contains the content.

The the various functions such as sethtml and gethtml are redirected to the
"blackboard" layer (content layer) as well as setsize, ect, resulting in the
containing layer, the cover layer and the blackboard layer being resized at
the same time

Basically it's to make a layer's content non-selectable and non-clickable
without the devealoper having to do more than myLayer.enableBlackboard();


before EnableBlackboard()
[myLayer]content[/myLayer]

After EnabledBlackboard
[myLayer]
   [TransparentCoverLayer]
      [BlackBoard]
         Content
      [BlackBoard]
   [TransparentCoverLayer]
[myLayer]

I helped only slightly to create and test this widget.  Tiru you out 
there?  Lars, please submit a bug for this, with a test page that 
illustrates the problem, and a screen shot is nice too if needed.  I'll 
take a look when I can, but I've got to learn the widget as well.  I've 
got a few other bugs I'm trying to figure out atthe moment.

This would be one of those bugs I'm trying to work on... well, maybe 
this is a new one, a second bug with ViewPanes.  If you notice in 
Mozilla, the scrollbars are not quite right.  Compare to IE6 if you have 
access to it.  The text selection might be another issue.  Can you 
further test this for me, to determine if the text selection is a bug in 
general in the API, or with other widgets, or only with ViewPane?  And 
also open a bug for this in the bug tracker.

I'm bound to forget bugs reports if they're tucked away in my mailbox. 
But if I search for open bugs, I'll find them quickly.  While you're in 
the bug tracker, take a look at some other recently opened bugs.  If you 
can fix any of them then submit a solution and a test case if needed.

Thanks!

Leif

I've seen it too and wondered.  Searching the source I find a few 
references to m/blackboard/i.
One comment in the template manager code reads: "// this will force a 
<layer> arround the inline html".

To what end, I'm not sure.

Check the following:

./docs/docs/quickref.dynlayer.html
./docs/docs/revision.html
./examples/dynapi.api.dynlayer-autosize.html

Can't seem to find anything in mailing lists, which is odd.  It's 
probably in the dev list.  Check that list prior to the CVS additions

[Dynapi-Help] What is enableBlackboard?

[Andrew G. <an...@ph...>]

In DynLayer, there is a method called "enableBlackboard". Can anyone 
tell me what its for?
I can't find any documentation for it and I can't follow the code. I'd 
appreciate it if someone
would give me a clue about its purpose.

Just curious,

Andrew.

I believe that is the DynAPI 2 or older way.  Currently we're not doing 
anything with DynAPI 2.  Ideally I'd like to update the older APIs, but 
right now I'm spending my time trying to fix bugs for a DynAPI 3 
release.  I'm not opposed to updating DynAPI 1 or 2, if someone came 
forward with something and said, "Here, I did it, I tested it, here's a 
bunch of test cases for previous and updated version, try it yourself." 
Then I'd have little extra to do but test, merge and commit.  Until 
then, I guess I can't be opposed to hacks that may work-around any 
broken problems.  But, it'd be nice if the user can turn the feature on 
or off globally, as well as per-site, incase we do get something fixed 
up.  But that's a long ways off, if ever.  Currently DynAPI 3 has moved 
the browser detect stuff into "dynapi/src/dynapi.js", though some may 
choose to install just /src/ on the site under a different dirname like 
/scripts/dynapi/dynapi.js or something.  So I don't think it would 
affect current or future versions.  But well, if anyone else sees a 
problem, be sure to speak up!

[Dynapi-Help] Opera may change its handling of old (and current?) DynAPI versions

[Hallvord R. M. S. <hal...@on...>]

Dear DynAPI developers and users,
I work for Opera Software with JavaScript testing and development. 
Currently one of the things I'm working on is a set of features that 
lets Opera adapt to broken JavaScripts. This builds on our "user 
javascript" feature which already is being used to fix broken sites.

As you may or may not be aware, older versions of DynAPI do not run 
well in Opera because they detect Opera as "Opera" and important 
parts of the script branches for NN and IE only. This means important 
objects and variables have not been defined and the script fails to 
run correctly.

As a fix for this, I've written a script which will detect when a 
page is about to use an external script with an address ending in 
"dynapi/api/browser.js". If this is the case, Opera will set its 
"navigator.appName" property to "Microsoft Internet Explorer" while 
executing that script.

This obviously has implications for any version of DynAPI that uses 
the same file name/directory structure. You may not be able to detect 
Opera reliably. If you believe this will cause problems for current 
or future versions please voice your concerns..

[Dynapi-Help] ViewPane & ObjectStacker

[<Lar...@gm...>]

Hi,
I'm using DynAPI 3.0 a few weeks and I think it's one of the most powerful
cross-browser DHTML-libraries I've ever seen. Nevertheless I had some
problems with two features I would like to use in my project:

1.) Object-Stacker:
If I add more than one ObjectStacker to the document, only the last inserted
ObjectStacker seems to work. I take a look at the source code but I'm not
able to give account of this phenomenon. Any Ideas?

2.) Mozilla/Mozilla Firefox-Problem with ViewPane:
If you click inside a viewpane which includes one larger DynLayer and move
the mouse downwards, the text inside the Layer is marked and the scrollbar
left the current view! The dynLayer.setTextSelectable(false) method of the
DynLayer-Class does not avoid this behaviour in Firefox and Mozilla.
Viewpane.jpg shows you the little bug for the viewpane-example. Did anybody
know a solution to avoid this mouse-dragging-behaviour?

Thank you for your help.

Greetings,
Lars

Re: [Dynapi-Help] Re: onclick events and getX()

[<do...@cr...>]

Okay.. instead of inserting the background layer the way you are now, What I
do is have a div in my html at the location i want my layer, then onload, i
use the Inline extension to pull out the position of the relative div in the
document, and position my layer accordingly.

I can't help but wonder if adding the layer to the dynapi.document (which
inserts it in the browser's DOM) then inserting it a second time with your
inset call.. try using the FireFox dom inspector (i think it's included, but
you may want to DL it from the FF extensions page) once you page is loaded,
you can browse through the document's objects to see if your layer is there twice.

cheers

P.S. Sample code that exhibits the error would be great.. make it much easier
to deterine the issue at hand :-)

Well, I haven't had the big breakthrough I was hoping for, but I did 
make some observations.

1) Onclick you can think of like two events: onmousedown and onmouseup. 
Therefore, a click event does not happen until the mouse comes back up. 
So you can't use a single click to pull a layer to the mouse and drag, 
if you use onclick event.  So, use onmousedown event.  Which leads to 
the second observation.

2) I think I see now what you might be experiencing.  When setting up a 
background layer, adding to that a layer with a photograph, and adding 
to that a layer that you move around (fetch and drag), then there's a 
problem.  The onmousedown event is passing the X and Y coordinates +8 or 
+9 or so.  The upper left corner of the fetched layer stops to the 8 or 
9 pixels to the lower right of the cursor.  Therefore you can never 
connect with a drag event.  If I remove the relative insert later in the 
document, the upper left corner of the fetched layer comes to a stop 
precisely underneath the mouse cursor.

It's hard to know the intent without having a precise yet simplified 
example of how the code needs to fit together in the end.  I can only 
guess something like you'll have some text or images or other layers, 
then you'll want to relatively insert this background layer, with it's 
photo and it's fetchable/draggable layer.  You won't know ahead of time 
how to precisely position the layer on the page, so everything must be 
done relative to the background layer.  Maybe there's another way to do 
things?  I'm still learning myself.  I definitely would like to 
understand where the offset is coming from.  I might have a hunch about 
some thing.  Anyways I'll submit a bug with my above observations so it 
will not be forgotten.

Right, but there's two 3.0 beta versions.  Please clarify if it's 
3.0.0-beta1 and 3.0.0-beta2.  Make sure you have 3.0.0-beta2.

Since we recently had a release, you shouldn't need to get CVS.  There 
haven't been any changes to that code yet.

I think I understand now.  Click somewhere on bg1 and have lyr1 move 
there.  Centered lyr1 around the point you clicked?  And then what 
happens?  Continue to drag without lifting the button and clicking lyr1 
to initiate a drag event?  I've never done that, but I would guess I'd 
add an onclick event listener to bg1, and have that handler move bg1, 
centered, and attempt to invoke a drag event on bg1.  I'd probably have 
a delay between the move and the drag, maybe half second or quarter 
second.

> Doug, I tried your example, but couldn't get it to load.

Well, we definitely should be working off the same example here.  I got 
his working with some tweaks of my own here and there, mostly just 
changing the path to the initial dynapi.js script and the subsequent 
setPath and fiddled with some layer sizes and positions.  I'll try to 
get a working example and post that.

[Dynapi-Help] Re: onclick events and getX()

[Bob J. <bob...@gr...>]

Hi,

Thanks for responding. To answer your questions:

1) I'm using the 3.0 beta that is available for download on the site. Shoul=
d I get the one off CVS? I'm not sure how to do that.

2) I'm on Windows XP. It doesn't work in any browser (firefox, IE, netscape=
).

Just to clarify, the dragging of lyr1 works fine. What I want to happen is =
when you click on the layer bg1, then lyr1 should move to that point. Hence=
, I need to know the x and y as set on bg1, not to the page. But bg1 itself=
 needs to be relative on the page. Does that make sense?

Doug, I tried your example, but couldn't get it to load.

I've made a simple example, which looks very much likes Doug's, so I 
just merged the differences.  It seems to work ok for me.

Re: [Dynapi-Help] onclick events and getX()

[<do...@cr...>]

Bob,
Some information that we need includes the following:
The make and version of web browser you are experiencing the poroblem in.
The OS on which you are running said browser.
The version of DynAPI 3.. is it the beta found in the downloads section, or
did you download the latest version from cvs.

That said I have mashed together the following test html.
In IE 6 and FireFox 1.0.6 the results are as expected.
The only thing that comes to mind is maybe the fact that your photo layer is
set to have an x and y of 0.

Thus, if the parent layer's top left corner is at 0x0 then the x and y values
of the child layer will reflect this (10 pixels from the top of a layer that
is at 0px from the top of the page will be 10px from the top of the page.

When I change the Photo layer's x and y to 10x10 and then move the child layer
to the top-left I get x and y of 0x0 as expected.

Hi.  Which 3.0?  ;-)  beta1 (2 years old) or beta2 (released last week). 
And which browser(s) yield the erroneous behavior?  To my understanding, 
getX/Y is relative to parent, and getPageX/Y is relative to page.  So 
the usage seems correct at first glance.  I'll take a closer look.

Hmm, what looks odd to me are these...

var photo = dynapi.document.addChild( new DynLayer(null,0,0,600,400) );
var bg1 = photo.addChild(new DynLayer(null,0,0,600,400));
var lyr1 = photo.addChild(new DynLayer(null,$x,$y,10,10,'red'));

Normally, I assign DynLayer directly to a variable, configure it, and 
when done use dynapi.document.addChild.  I'll try both ways and see what 
happens.

> I have a relative layer down in the html: 
> dynapi.document.insertChild(photo,'relative');

This I don't understand... you already added the DynLayer "photo" to the 
document once above, now you wish to insert it?  So there should be two 
instances, is this correct?  Is it even possible, again, I never tried 
that.  :-)  I'll fiddle around and get back later today.

Hi,

Can you give more information?  Which DynAPI version?  Which OS and

[Dynapi-Help] scrollbars

[Guillaume S. <gui...@ge...>]

Hi,

I'm using the dynapi embedded into a cartographic front-end called 
MapSurfer.
The dynapi helps to create layers in which are created a map, a 
scalebar, some info etc. On small screen, I would like to have a 
scrollbar, and I use scrollbars=yes on my frameset. But when I use the 
scrollbar, the layers automatically come back on the initial position, 
making a blinking effect and not allowing people to scroll.
Have you got any idea about that ?

[Dynapi-Help] New dynapi website

[Andrew G. <an...@zo...>]

Hello All,

I have upgraded the DynAPI website on sourceforge.  I'm hoping to 
revitalize this project and my immediate aim is to help produce 
DynAPI-3.0.0-final. There is much work to be done to reach this goal, 
particularly documentation, testing, and bug fixing.

The new website should be a valuable resource for collaboration amongst 
developers and users.

The old website was based on phpWebSite-0.7.6 and phpWiki-1.2.0 (both 
*very* old). I have installed phpWebSite-0.10.1. Because this skips 
several major releases, it was not possible to transfer all the content 
of the old site to the new.

The old website is still available, but at a different URL:
   http://dynapi.sourceforge.net/archive/dynapi/

The new website is simply at:
   http://dynapi.sourceforge.net/

And the old site at
   http://dynapi.sourceforge.net/dynapi/
now redirects to the new site.


None of the user account records could be transferred to the new site, 
so you'll need to register again. Many accounts never worked on the old 
site anyway, because the password encryption ceased working where 
SourceForge upgraded to php-4.3.

The old "doccenter" was based on phpWiki. The new phpWebSite includes a 
wiki module, so I haven't tried upgrading the wiki. I'm inclined just to 
move content, one page at a time, from doccenter to the new wiki module.

The new phpWebSite CMS contains many modules, most of which I haven't 
explored yet.  If you're interested in DynAPI and have the time and 
inclination to help build the new website (it's still fairly empty), 
then please get in touch with me - your help will be very welcome.

Let see if DynAPI can have a future!
