Disabling print range settings?

[Enrico Tröger]

Hi,

is there any way to disable or overwrite the print range in
GtkPrintSettings?

The implementation of printing in my application currently doesn't
support a range of pages. So I'd like to disable the selection of such
or at least to overwrite the user's choice.

I tried this in the begin-print signal handler like this:

GtkPrintSettings *lsettings;
GtkPageRange range;
lsettings = gtk_print_operation_get_print_settings(operation);
gtk_print_settings_set_print_pages(lsettings, GTK_PRINT_PAGES_ALL);
gtk_print_settings_set_page_set(lsettings, GTK_PAGE_SET_ALL);
range.start = 0; range.end = dinfo->n_pages;
gtk_print_settings_set_page_ranges(lsettings, &range, 1);
gtk_print_operation_set_print_settings(operation, lsettings);

But this seems to have no effect at all.
The draw-page signal is fired only for the user selected pages but I
need it to get fired for all pages.

Any ideas?

Regards,
Enrico

Wouldn't it be better to work on supporting a range of pages??
Easier said than done, I know, but still...  e.g. print to
/dev/null or a temporary file first, and notice where the
page breaks were...

Sure would it be better but it would be also more time consuming...
the long term goal is of course to support ranges of pages but as long
as it isn't implemented printing with a given range ends in the amount
of pages the user specified but the actual content always starts at
page 1.

I thought of something similar: in the begin-print handler, I call the
draw-page handler for all pages with a flag set to prevent actually
adding any contents to the layout except for the pages that are
desired. But it still needs to get done ;-).

Understood.  On the other hand, one day you'll need to undo whatever
hack you put in now... and you'll have to deal with complaining users
throwing their dirty socks at you.

I know, I know, and I'm not really helping very much, except to say,
don't do the quick hack, do the right thing, if at all possible :-)

This is already the case ;-).
I guess I really should make my code working with a given range of
pages :(.
