[Xerte] displaying variable info in text icon

[Dave Burnett]

Alternatively, you can hang all the paging code off the nav buttons,
set up a blank text field somewhere and use setText to update it:



e.g. code under Next button:



page = i_main_frame.currentPage+2;

// i_main_frame= framework pages are attached to, +2 because 0 based 

page_count_display.setText('<pgcounter_text>Page ' + page + ' of ' + page_count + '</pgcounter_text>');

//page_count_display is empty text icon with text field positioned correctly

prev_page_rs._visible = 1;

//turn on the Previous page button (it starts out hidden)

if (page ==  page_count) {

next_page_rs._visible = 0;

}

//turn off the Next button at end of pages

i_main_frame.gotoPage((i_main_frame.currentPage+1));

//navigate

 

You can ignore <pgcounter_text>, it's a css style tag.
