08e50934c9 canvas: add scroll offset info to Item::dump() 2021-12-10 17:16:10 -07:00
7e80111d92 Canvas: Fix notification to parent of show/hide status
This was changed in fc9840f2a9 to hard code a "false" argument describing
whether or not the child bbox had changed. This causes the parent to not
recompute its own bounding box when a child is shown/hidden, which is
incorrect. We now force it to true, which may be overkill for some purposes,
but at worst will just force an unnecessary bbox re-computation and nothing
more.

0296b0b0cb canvas: don't call ::size_allocate() for children unless there is just one child and it is "layout sensitive
the dumb/Item version of ::size_allocate_children() doesn't do anything but give its full allocation to children, and if there
was more than one child, this could not be done in a "dumb" way. Likewise, if the sole child is not layout sensitive, it
doesn't care about size allocation

860d43697c Canvas: propagate ::size_allocate() down the item tree
This previously wasn't done because of fear that it would affect the traditional fixed-sized canvas,
but only items that _layout_sensitive (i.e. are packed into a constraint packer directly) will
actually do anything in ::size_allocate().

Possibly might want to relax this to cover items that have a constraint packer between them
and a root group.

12b4807bc9 add a very (very) basic resize/layout design to the canvas
Items call ::queue_resize(), which sets a flag in the canvas; at next idle, we call
Canvas::layout() which walks the item tree and recursively calls layout (depth first)
on all items needing a resize.

Only Container types implement layout, and so far only Box

4fa4b9a135 remove use of boost::optional to define "undefined" Canvas::Rect, and use Rect::empty instead.
This commit includes Rect::operator bool() which might be a candidate for removal in a future commit, in an attempt
to make the meaning clearer

74be550698 change Item::visible() to Item::self_visible(); add Item::visible() which returns accurate visibility
Child items will be hidden when their ancestors are hidden. The old ::visible() implementation didn't reflect this. In addition,
when changes are made to hidden items (new definition of visible/not visible), don't bother to request redraws, since this will
be done when the item becomes visible again.
