[Gambas-user] Trying how many pages before printing

[Rolf-Werner Eilert]

Hi folks,

The only thing that keeps me from actually converting all my Gambas2 
stuff into Gambas3 is the printing function. There are situations when 
you don't know how many pages you will end up with when starting to 
print. For instance, there are tables or longer texts which might be 
more than one page - or not.

So it's necessary to figure out how many pages to print prior to start 
printing. In case of a simple line-by-line text or table, you can simply 
compute the space needed in advance. But in some cases, I have much more 
complex situations, and then it would be easiest to have a way to run a 
simple pre-print and count the pages.

In those Gambas2 projects I mean, I have e. g. a printing function that 
runs in a DO LOOP. When printing reaches the end of the page, it simply 
opens a new page, jumps to the start position and continues printing there.

How do you solve this for Gambas3? I thought, a simple way would be to 
order a single page, printing into a temporary pdf, and look if there is 
another page needed, order another one-page print, and so on. Counting 
each page, you produce only a one-page temporary pdf. Then you start the 
actual printing with the counted number of pages.

Am I completely wrong here? Do you know a better/easier way?

Thank you for any input!
