- Display a meaningful error message to the user when adding or trying
to play a video
- Make sure the video placeholder is visible even after switching pages
The previous solution didn't really have any effect; only a handful of
settings were in the mUserSettings or mAppSettings at the moment it was
called. The better solution is to just call value() in the constructor
of UBSetting, which means the setting is cached as soon as it is
created.
- Sort by Z before duplicating a selection (so that relative Z's are
kept)
- in UBZLayerController, iterate only through UBGraphicsScene's fast
access items, not QGraphicsScene::items
- Defined constants in UBSettings for highlighter preview circle colors
- Switch between light and dark colors when changing backgrounds
- For eraser: use color settings that were defined in UBSettings (they
were ignored since the preview circle was added)
When a video is first loaded (placed on the scene), we play/pause it to
load the first frame; but this was also called when the video was
manually stopped. To avoid this, a mStopped attribute was added to
UBGraphicsMediaItem. It is set to true only when the video is stopped by
the user.
The documents' metadata.rdf file is now persisted only when a scene in
the document is also persisted; as well as when the document is modified
(trashed / path changed) in the the Documents pane.
Code was cleaned-up a bit too (added a forgotten return value, etc)
Some settings were changed between v1.02 and 1.10 (current), and some
of these changes cause OpenBoard to crash at launch. This commit adds
a function to check for these specific new settings, and wipe the old
values if they are found.
This avoids problems when the user upgrades from 1.02 without deleting
their configuration file.
(This is an alternative to having a post-install script, which would be
ineffective in a multi-user configuration)
This should cut down on disk access. Instead of loading and saving
settings directly through QSettings instances (which occasionally
read and write to their associated file; but there is no way to control
how often this happens), they are now added to a QHash for in-app
access.
Save() and load() functions were also added to enable manually saving
the settings, and loading all settings from file, respectively.
During trashing of multiple documents, a new document was selected
every time that one was moved to the trash -- even if it was about
to be trashed itself. This is no longer the case; the
selectADocumentOnMultipleTrashing() method was added to select the
first unselected document found (but this is currently not used, as
it seems OK to just select no document when we have just deleted a
whole selection)
That function requires access to variables that are initialized
in videoItem and audioItem constructors, so it can sometimes fail
when called from the superclass's constructor.
It might be an idea to avoid those calls altogether though
