[Xerte] Page Templates - Interface Customization

[Julian Tenney]

I suspect the swf hasn't loaded yet. You're trying to get at a timeline
before the swf has loaded and initialised. Use the onLoad event on the
icon to try the same code that sets your text, or some other code that
runs later,

You might want to look at using a component icon rather than a graphic
icon, as you can pass an initObject into an init function in your swf
when it loads up, rather than handle events, and certain things -
FileLocation, debug(), rootIcon (I think) are passed into the swf for
you to more conveniently use.

Thanks for the help everyone -- I was able to get my navigation buttons
in my .swf working hand in hand with the rootIcon navigation functions.
However, I'm having a problem similar to one another user was having
with some dynamic text boxes that I use to display the current page and
a total page count. I've done a couple of things to try to debug and ran
up against a problem I thought you might help with :)
 
In my .swf I can use the code:
 
this._parent._parent.rootIcon.controller.numpg_txt.text =
this._parent._parent.rootIcon.pages.length
 
...in a button which will set the numpg_txt dynamic text box to the
total number of pages.
 
However, in the onInit event, I use the code:
 
rootIcon.controller.numpg_txt.text = rootIcon.pages.length
 
...which doesn't work at all. I have established that the onInit script
I wrote is firing. I've also used debug() to establish that I have the
correct hierarchy, but according to the onInit script, numpg_txt is
undefined. Is there a problem with a Xerte script utilizing components
in a .swf? I notice that in the default interface there is a current
page / total pages count -- is this a .swf/.fla and if so, is the .fla
available?

> I can definitely try that change to the button, but what concerns me
more is when I attempt to pull rootIcon.CurrentPage to a dynamic text
box, I get an "undefined" value. Seems like my .swf can't find the
"rootIcon"...


It helped me with the swf relationship structure when I started to think
of it like a directory tree on a hard drive.

If you have any programming background, you know that C:\ is also
referred to as "root".
So if you think of the Xerte engine swf as "root", (rootIcon), loading a
swf into it is like creating another directory in C:\ or root.
So now I have C:\my_swf.

To have my_swf talk to anything in root, I have to add a direction to
look "up" a folder in the directory tree.
In DOS I would use ../my_swf, the ".." being shorthand for saying "look
up a directory from 'my_swf'", or "look in my parent directory".

Same as a loaded swf.
You have to tell the swf to look "up" a directory from where it is
(this), to it's parent (this._parent)

So if my_swf loads another swf, it's like creating another directory and
another level in the tree:

C:\my_swf\swf_loaded_by_my_swf
Another layer of depth in the tree, so for swf_loaded_by_my_swf to talk
to root, look up 2 directories:

this._parent._parent
