[Xerte] Jumping from flash menu within Xerte

[Dave Burnett]

"When you navigate away from a page, it’s contents are cleared
out, although the page itself remains – it holds its XML node which is what
gets re-parsed if the page is shown again. It is empty at that point."

Not quite sure here what is being referred to.
"Contents cleared out" - what is actually being displayed on screen, i.e. the clip is unloaded.

"The page itself remains" - That instance of the class m/c remains?
Or the XML node remains?

"It is empty at that point" - what is empty?

I'm sort of following along on another query as to is their any equivalent of a Call/Return navigation. I didn't think so because there is no such thing as a CallStack table or any way to retain what should remain on screen.
I guess you could fake one with enough code?

[Xerte] Xerte Dynamic Templates tutorial - clarification








That’s right.

 

A page is refresehd when it is nvaigated to: it’s icons are
recreated from the underlying XML, and script re-runs.

 

When you navigate away from a page, it’s contents are cleared
out, although the page itself remains – it holds its XML node which is what
gets re-parsed if the page is shown again. It is empty at that point.

OK, a simplistic question.



I've been looking at the back end of this thing for so long I haven't really
paid attention to the actual engine functioning. :-/



Am I way off the concept here: 



Engine loads XML structure into memory.

Now, it does not actually build any of the objects until requested.

So root and IFC and everything until the flow is somehow halted load.

Now I navigate to page 2.

Engine reads that node, loads appropriate clip and sets properties as defined
in XML.



So that is why variables for instance, when they change, have to be explicitly
refreshed in an existing "icon/mc".

The display or whatever is being statically built as encountered. If something like
a variable is changed, the variable is changed in the XML structure in memory,
then the node needs to be reloaded.



It is so difficult to unload(RootIcon) the flowline metaphor from my brain.

;-)

rootIcon.pages[index].variable
= value

Could I set a variable on page 2 prior to jumping to it?

In this case, 'page2' is the
iconID to navigate to? That ought to work. Can you debug(rootIcon) OK? Load the
flash movie up as a component, rather than a graphic icon to get rootIcon and
debug() in the flash movie's timeline, otherwise you'll have to call
_level0.engine.rootIcon.navigate().





 





Does that help?

If I build a flash menu and import
it at the start of my Xerte flowline... how would I jump to frameworks within
Xerte? 

 

rootIcon.navigate('page2');    
etc  doesn’t seem to work in the flash menu.

 

Is there any particular type
of navigation I should be doing from the imported flash menu to
frameworks/modules within Xerte? What would work?

 

Thanks
