Title: $V{#PAGE_COUNT} on script
Post by: Kiko on July 14, 2017, 08:31:41 pm

The variable $V{#PAGE_COUNT} doesn't work on the script block $S{} ?
I used $V{#PAGE} and works fine but the $V{#PAGE_COUNT} gave me the error "SyntaxError: parse error".

Unfortunately, you can't use $V{#PAGE_COUNT} in script because it is a second pass variable and is not accessible in time when script is executing

Thank you for the quick answer, but my problem persist.
How to hide or show an item based on the current page ?
E. g If is the last page I have to hide the item, otherwise I have to show it in the other pages of my report.

Yes, I understand your problem and will try to find a solution

Could you elaborate on what type of objects do you want to hide on the last page?

The object is a Text Item.

Where are the items located ? May be on the pagefooter or pageheader? The problem is that in the first pass i don't know what page is rendered last or not, until the last page not finished. if i hide items on the second pass the band will not be resized

The item is located on the Page Footer band.
I'm using Qt 5.9.1 and my datasource is provided by data transfer and linking to a report generator by SIGNAL­-SLOT approach.

Is it possible to create a parameter to force a 3rd pass where you could have access to the second pass variables in the script blocks or resize the bands ?

Wouldn't be possible to access the objects of my report before the preview/print ?

Can it be enough to hide pagefooter on last page ?

Title: Re: $V{#PAGE_COUNT} on script

I can't hide the pagefooter because I'm using other items on it.

Hey Alex,
I downloaded the last version from GitHub.
Thank you for your modifications, will be very useful to me.
However the system variable #IS_FIRST_PAGEFOOTER is always returning false.
Can you fix it ?

This is the script that I'm using to test the version:

Code: [Select]

$S{
  if($V{#IS_FIRST_PAGEFOOTER}){
   "a"
  }else{
   "b"
  }
}

I have fixed #IS_FIRST_PAGEFOOTER :)

Subst if you need #IS_FIRST_PAGEHEADER i can add it :)

#IS_FIRST_PAGEFOOTER works fine !

Thank you for adding these two variables, it helped me a lot.
