We now require that the two clicks that make up a double-click be no
more than 4px apart.
This fixes the annoying behavior where you'd often get incorrect
double-click events on GUI widgets.
This breaks GSortingProxyModel selection preservation across resorts.
I'm not yet sure how we're going to solve that, but it's going to have
to work a bit differently than before, since the model itself no longer
knows what's selected.
Selection is now managed by GModelSelection which allows us to select
any arbitrary number of items, and to have different selections in
different views onto the same model. Pretty sweet. :^)
Each GAbstractView now has a GModelSelection backed by a simple
HashTable<GModelIndex>. When the selection changes somehow, the view
gets notified via the notify_selection_changed() callback.
In the future it will probably make sense to move to using some kind of
ranges as the internal representation instead.
`GTabWidget` now allows the user/caller to get the currently active
tab widget, meaning that actions that are applied globally (such as
an 'Apply' or 'OK' button) can now react to specific tabs etc.
An interactive application to modify the current display settings, such as
the current wallpaper as well as the screen resolution. Currently we're
adding the resolutions ourselves, because there's currently no way to
detect was resolutions the current display adapter supports (or at least
I can't see one... Maybe VBE does and I'm stupid). It even comes with
a very nice template'd `ItemList` that can support a vector of any type,
which makes life much simpler.
Now that the kernel supports thread-local storage, we can declare errno
with the __thread keyword, which causes it to be per-thread.
This should fix all the stupid issues that happen when many threads use
the same errno. :^)
This patch adds support for TLS according to the x86 System V ABI.
Each thread gets a thread-specific memory region, and the GS segment
register always points _to a pointer_ to the thread-specific memory.
In other words, to access thread-local variables, userspace programs
start by dereferencing the pointer at [gs:0].
The Process keeps a master copy of the TLS segment that new threads
should use, and when a new thread is created, they get a copy of it.
It's basically whatever the PT_TLS program header in the ELF says.
We were already borrowing a getopt() from the BSD family until the day
we write our own. This patch borrows a slightly more modern one so we
also get getopt_long().
Fixes#190.
See also #91 for the desire to eventually NIH our own getopt()..
This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)
