>> About the "arrangement system", the main idea is:
>>
>> You make a report by telling how each element is positioned relatively
>> to each other, or relatively to its parent. That way, the report can be
>> drawn whatever the page size is.
>>
>> How it is done concretely? It's taken from the GUI arrangement system:
>>
>> - You have containers that arrange their children vertically,
>> horizontally... and that know how much space they have.
>>
>> - You have display elements that can have either absolute sizes
>> (expressed in various units). They can also marked as expandable to let
>> their parents expand them if there is space available.
>>
>> The root parent is the page itself. As the user tells the size of that
>> page, we can recursively compute the size of all page elements according
>> to the container and child elements properties, and then print the report.
>>
>> Moreover, the root parent is clever enough, if it has not enough space
>> for its children, to spread accross new pages automatically. So there is
>> way to tell which elements are repeated between different pages (so that
>> you can create headers and footers), and which are not. Fabien could
>> tell you more about that.

> as new page.

> array is repeated in the second page. if the array header have fixed
> at true then you have it on each page.

>> Of course, for reports having a few elements, all that a bit complex.
> Not sur ... or for really few.
>>
>> But for real reports made by real guys who have clients having many
>> paper formats and many different printers, that will save you a lot of
>> worry.

>> If you don't understand how to use Gambas GUI containers, you won't
