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 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]
Cheers

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 do...@cr... said: > > > 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] > > Cheers > > Leif W <war...@us...> said: > > > > From: "Andrew Gillett" <an...@ph...> > > > Sent: 2005 August 15 Monday 19:01 > > > > > > In DynLayer, there is a method called "enableBlackboard".

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

Hi everyone,
Doug is correct about the functionality of the black
board. That's exactly what it was design for.

Hi Raymond, good to hear from you! Thanks for the confirmation. And Doug, thanks for the visual, it helps a lot. I'd like to see a doc page for that, including the caveats noted (until they're resolved, pending testing and discussion as needed). If someone has the initiative, do it, otherwise I'll get to it eventually. :p Leif |
