The constructors of those classes now accept a string to be wrapped, instead
of a vector to be modified with split lines inserted into its middle.
Along with this conversion, manuals for applications stored in OPK packages
are now transferred into a string without garbage at the end.
This does away with per-link selector directories in link files. It is assumed
that, if a user has access to write files to be launched by an application at
some location, he or she also has access to write files in the previews/
subdirectory under it.
This breaks one thing: the "params" option of the links must be
only one parameter (without spaces). The only way to actually
set this option being to edit the config files manually, it is
pretty safe to assume it will never contain two parameters.
The comment of this code indicates that it is needed for
SDL apps to work correctly.
However, I don't see any valid reason for the apps we
launch to be running in a different group.
Removing it didn't make any apparent difference, so unless
I'm proven wrong, it'll stay gone from now on.
LinkApp::drawRun() assumes the layers below are already painted when
it is called, but this was not the case. With single buffering, the
previous frame was still there so it still looked good, but with
double buffering the buffer typically contains an outdated screen.
Long term I think the launch should happen at the outermost scope,
so all destructors get a chance to run. This commit is a small step
in that direction, by exiting the main loop before launching.
If the application in question daemonizes, it will continue running
no matter whether we start it with system() or execlp(). So I don't
see a reason for this feature to exist and removing it means less
code paths to worry about.
Originally the font implementation was based on SFont, but it was
recently replaced by an SDL_ttf based implementation, so the name
no longer made sense.
The code still has a lot of overlap with the other methods of Link and
LinkApp, but at least it is in the same place now.
Since this was the last outside use, setIconPath() could be declared
as 'protected'.
