[Xerte] Page Templates - Interface Customization

[James McCleese]

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
