Added member functions to undo::UndoHistory and
app::DocumentUndo to iterate all states of the undo history.
Also we’ve added app::DocumentUndoObserver to see when new states
are added in the undo history.
This bug was introduced in e730b9095870bd09c5d2330982e1abf9bb02e422
to fix memory leaks in "app". Now a new UndoCommand::dispose() member
function was added to fix this problem.
Also std::function<> and std::tr1::function<> was removed from the test.
We're in the middle of a transition between OS X SDK 10.4 to 10.9/10
and this brings some problems.
Undoers were little objects to swap/revert an action. They didn't
execute the action itself, they just revert its previous state. Now
undoers were replaced with cmds: A cmd is an object that
executes/undoes/redoes just one action.
Changes:
* Remove old undo library and app/objects_container_impl.cpp
(now we use the doc::ObjectId directly to store undo info)
* Remove all Undoers from app/undoers/
* Replace DocumentApi impl with little Cmds in app/cmd/, these
cmds handle execute/undo/redo of each action at the logic layer
* Remove doc::Dirty object
* Remove doc::Settings: all undo configuration is in the app side
* Move undo options from app:ISettings to app::Preferences
* Rename UndoTransaction to Transaction
* Create a CmdSequence to store a sequence of Cmds (as now the new
undo library doesn't support open/close groups)
* Add doc::get<T>(ObjectId) function to get any kind of object
from the doc library by its ID
* Add Cel::document() and Sprite::document() members
* Add Sprite::cels(frame_t) to get all cels in the given frame
* Add Layer::displaceFrames() member function
* Move the "allow non-linear history" flag from undo2::UndoHistory
to app::DocumentUndo
There were problems calling a pure virtual function (IFileOpProgress
implemented by OpenFileJob) when we are already in ~Job() dtor. So we've
to wait the background thread (added Job::waitJob() function) to join
the thread so it can use IFileOpProgress safely.
Also the save process of .ase files now can be cancelled (it wasn't
possible before).
- Add HAVE_CONFIG_H wrapper to #include "config.h"
- Removed widgets namespace (it's in app now)
- Move some functions from src/file/file.h to src/base/cfile.h
- Move Vector2d to base library
- Rename MenuItem2 to AppMenuItem
The UndoHistory was simplified, m_enabled/label/modification members
were removed because they aren't part of the undo library goal.
Now the "label" field is part of Open/CloseGroup undoers, and all undoers
must be enclosed in a group (this restriction is only for the app, the
undo library doesn't have this restriction). In this way, the
label/modification information is exchanged between an
OpenGroup <-> CloseGroup pair only.
+ Added Undo::graftUndoerInLastGroup() member function.
+ Modify the PaletteEntryEditor to group a sequence of SetPaletteColors
undoers in the same group using the new Undo::graftUndoerInLastGroup().
+ Added a new attribute for each undo item (undo::Modification).
+ Each item now modifies or does not modify the document (e.g. selection
actions do not modify the document).
+ Added an asterisk in tabs when the document is modified.
+ Added "undo" library (undo namespace).
+ Moved UndoHistory to undo namespace.
+ Added Undoer and UndoersCollector interfaces.
+ Converted old UndoStream to UndoersStack class.
+ Added new "undoers" namespace and moved each Undoer implementation
(classes to undo different actions) to "undoers" directory.
+ Added IO operations to "raster" objects (image, cel, layer, palette,
mask).
obtain any kind of objects (not just GfxObj).
+ Removed GfxObjId.
+ Added ObjectsContainerImpl.
+ Use UniquePtr for each member in Document to avoid memory leaks in
Document() ctor.
+ Removed RasterModule class.
