OK, i see that for (say) the Hotlist window, which has the tree
structure where you can click the "+" to expand a branch into twigs.
but i don't grasp what puts the "certificate" display, about which i
originally aksed in this thread, into the treeview category. after
all, it displays only one item.
It's just a programming term: the hotlist, global history, cookies and
certificate display all happen to use a display widget (supplied by
NetSurf) known as the "treeview" to put their content into the window.
Incidentally, it was this that caused the RISC OS support kerfuffle last
year: the treeview widget and the code that used it originally resided in
our frontend (so the others didn't get a look in). When it was moved into
the core so that it could be shared around the other platforms, the RISC
OS code needed some surgery to handle the loss. It was this surgery that
didn't take account of the horizontal scroll bar properly.
the Hotlist, i note, can be dragged wider, though it has no
horizontal
scrollbar.
It does now: that was the point of the most recent fix, because the
problem that affected certificates could also affect the other tree
windows in more extreme cases (if the text line was wider than your
monitor).
