The objective of these changes is to create a more testable doc/logic API.
Included changes:
- Added doc::Context, doc::Documents (the old app::Documents),
and doc::Sprites (and observers for each)
- Added raster::Sprite::createBasicSprite()
- Added doc::ColorMode (equal to raster::PixelFormat)
- Added some methods to doc::Document: context(), sprites(), sprite()
(to replace app::Document::getSprite()), width/height(), colorMode(),
name(), and close()
- Moved app::DocumentObserver/Event to doc::DocumentObserver/Event
- Replaced app::ContextObserver with doc::DocumentsObserver and a couple
of signals.
- Renamed app::Context::getActiveDocument() with
doc::Context::activeDocument()
- Renamed app::Context::getActiveLocation() with
app::Context::activeLocation()
- Removed app::ContextObserverList
- Removed app::DocumentId (now we can use doc::ObjectId)
- Removed app::Context::getSettings()
This is a work-in-progress, dropRange() must be reimplemented. Now that
the Timeline uses LayerIndex, we could change Timeline::Range to
DocumentRange and create unit tests for the logic side.
There are cases where we need to modify the list of observers of certain
entity when we are in a notification loop (i.e. iterating its observers).
E.g. A general update notification about the current document to all its
observers could create the mini editor, which is a DocumentObserver, so
a new observer is added to the list in the same notification loop.
Anyway, as we cannot modify the observer list (std::vector) when we are
notifying them (any modification in the std::vector invalidates
its iterators), the fix is quite easy (but not optimal): we can create
a copy of the observers list so we can iterate the list.
Note: If we have performance issues about this, we could try a std::list,
but at the moment this fix is quite enough.
On WinXP classic theme we receive a WM_NCHITTEST messages for the
scrollbars, and as they overlap the resize borders (see WM_NCCALCSIZE
handler) we have to return a proper value as if they really were the
borders of the window.
Note: Scrollbars are still visible in classic theme, that is just ugly,
but at least the user can resize the window from bottom and right edges.
