Module progress_page 

What scenes 4b and 6 share: they are the same screen at two moments of the run, with the same control ids.

Constants

PROGRESS_SCALE

Progress bar steps; bytes would overflow PBM_SETRANGE32’s i32 past 2 GB.

Functions

finish_page^⚠

Shows the finished run’s state, then has the sheet move to next by pressing Next, or by page id when the next page is not the one after this.

init_progress^⚠

log_line^⚠

Appends to the run log and adds the line to the pane, where the page has one; show_log has brought the pane up to date when the page appeared.

on_cancel^⚠

Always vetoes the close: a confirmed Cancel raises the flag, and the worker’s Cancelled then walks the wizard on to the summary. Scene 6 disables the button, since the engine cannot stop between files.

set_progress^⚠

show_log^⚠

The whole log so far, for a page coming into view: lines are logged from pages that have no pane, so this page has not seen them.

show_progress^⚠
