This function is used to access how far into the song the current audio
position is. The value is returned as a percentage of the total length
for easy use by the UI.
I always want to find tags if it's possible. Since I already have a way
to find the tags, it's fairly simple to tag a random file and pass the
result back to the UI.
Namespaces make code easier to follow, and remove the need to mangle the
beginning of function names by using ocarina_*() or libsaria_*(). In
other words: "namespaces are one honking good idea. Let's have more of
them!"
The SourceModel declares an insert() function that is called when
filling the list. I have defined this function in a way that the list
will be filled in through repeated calls to insert()
The source model class is used to more tightly control how songs are
inserted into the UI. I provide an insert() function that the library's
for_each() function can take advantage of. This allows me to directly
insert songs into the UI rather than having to use a static function as
the "middle man"
This function will generate a Track object based on the current file
stored by the audio. I then pass this object to to provided function so
the UI can be updated.
It really should go into the include directory. I don't want to use
relative paths to include header files in a subdirectory... I don't know
why I even did it in the first place!
This cleans up the idle task code a lot, and reduces the size of
ocarina.bin to less than 1MB (with full debugging). It probably won't
stay there long...
I combined reference counting with the get_footer() function to make
using it easier (no manual reference counting). put_footer() will
deallocate the widget if the reference count is 0 (this is already done
by the g_object_unref() function) so it should work in a sane way.
Calling the remove() function will destroy the footer if it has no other
references. To prevent this, I need to call g_object_ref() add a
reference to the widget.
If the user no longer wishes to track a certain path, they can remove it
from the library. Note: it is unsafe to remove a path from the library
while that path is being scanned. This could potentially lead to a
segmentation fault.
The code was a bit messy and didn't make use of namespaces very well.
By converting to a set of functions (instead of a class) I can use
each function as a function pointer if I want to. I am also able to
remove libsaria/library.cpp since this was just a set of wrapper
functions to the old static class functions.
I register the idle task when there are events in the idle queue and I
remove the idle task once those events have been processed. This should
cut down on CPU usage when nothing is happening.
When the first task is queued, I trigger a callback so the UI can start
processing when idle. I return the size of the queue from both
run_task() and queue_task() so the UI knows when to stop processing
callbacks.
I don't actually perform a library update at this point, but I do create
a new task and add it to the update queue. When the run_task() function
is called, the task is removed from the queue and deleted.
