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.
This is an huge refactor to avoid handling Allegro FONT directly. Some
changes:
* Add she::System::defaultDisplay/Font, createRgbaSurface, loadSurface,
and loadRgbaSurface.
* Rename she::CreateSystem/Instance to she::create_system/instance.
* Remove ui/font.cpp and move ui/fontbmp.cpp to she library.
* ui::IButtonIcon uses she::Surface instead of BITMAP.
* Rename she::LockedSurface::drawAlphaSurface -> drawRgbaSurface
* Rename ui::SetDisplay -> set_display
* Rename _ji_font_text_len -> ui::Graphics::measureUIStringLength
