[Xerte] Controlling Nav buttons

And then, a minute which seemed to last an hour but was only a minute... passed.

The fog is slowly lifting.
So no code effect if it is not on the stage.
But if I mess with the underlying nodes I could pre-set it.

You’d be back to page one of the FW, with the interaction rebuilt, so it would behave as it did the first time.

The script approach was the first I considered, but then I wondered what happened if the user activated that script, then navigated away from that FW.
Would the button be visible on return to the FW (because the interaction would be rebuilt)?

So in your button script do this
//next button
 
If (fw.currentPage < fw.pageCount – 1){
  //navigate
} else {
  btnNext._visible = false;//or whatever
}

Thanks Paul.  I may need to structure some of the stuff that way.

In this case I have regular pages of content hanging off an FW.
Trying to figure out the analogous way to set up an:
Active If: "PageCount(ID)>CurrentPage"
So if on page 1, the "Previous" button is not available, and same thing on the last page attached to the FW.

I took a peek at the default interface, but the buttons seem to stay active, they just don't navigate anywhere at the end of "travel".

I use a Decision icon to hold content while on a page. I navigate through the Decision icon pages until all of the content has been displayed, then exit the Decision icon. I have my Next button interaction following the Decision icon, so it isn’t displayed until you exit.

Now I have a handle on global navigation, on to local navigation.

I can see a few ways to do this, but is there a best practice for hiding/showing Next and Previous buttons in a classic page turner setup?

Giving the buttons in question an rs value and using the Visible property looks like the way to go, but where's the best place for the controlling code?

Cheers,

Dave
