This function is added to separate the desktop toggling functionality
from the "Show Desktop" button in the taskbar and to enable calling this
behaviour via a keyboard shortcut in a later commit.
This makes the wrapper more like the rest in LibCore, and also
removes the annoying limitation of not supporting arguments.
There are three overloads one for String, char const *, and StringView
argument lists. As long as there are <= 10 arguments the argv list
will be allocated inline, otherwise on the heap.
With this change you can now set the theme and background color at the
same time in the Display Settings. Before if both were changed
before hitting 'apply' the theme background color would overwrite
the custom background.
This is useful, for instance, in games in which you can switch held
items using the scroll wheel. In order to implement this, they
previously would have to either add a hard-coded division by 4, or look
up your mouse settings to adjust correctly.
This commit adds an MouseEvent.wheel_raw_delta_x() and
MouseEvent.wheel_raw_delta_y().
I've attempted to handle the errors gracefully where it was clear how to
do so, and simple, but a lot of this was just adding
`release_value_but_fixme_should_propagate_errors()` in places.
pledge_domains() that takes only one String argument was specifically
added as a shortcut for pledging a single domain. So, it makes sense to
use singular here.
In order to avoid having multiple instances, we were keeping a pointer
to these singleton objects and only allocating them when it was null.
We have `__cxa_guard_{acquire,release}` in the userland, so there's no
need to do this dance, as the compiler will ensure that the constructors
are only called once.
In most applications, we invoke tzset once at startup for now. Most of
these are short lived and don't need to know about time zone changes.
The exception is the ClockWidget in the taskbar. Here, we invoke tzset
each time we update the system time. This way, any time zone changes can
take effect immediately.
... into QuickLaunchEntry class. It will be used to implement adding
plain executables to the taskbar. For now, it adds TRY() error handling
to app launching :^)
I personally find it very distracting when the clock continuously
shifts around as seconds tick. Because we're not using a monospace
font for the clock, this is to be expected since each number has a
different typographic width.
However, a tradeoff can be made to make this slightly less distracting.
Instead of _perfectly_ centering the time string for every given
possible time, we can center it once based on a constant measurement
and render the rest of the string as left-aligned.
The advantage is that the clock no longer shifts around anymore while
seconds tick. The disadvantage is that the time may sometimes be not
perfectly centered by a pixel or two for certain numbers. Personally,
I find the tradeoff well worth it, and I don't think I would even
notice the imperfect centering unless I was specifically looking for
it and watching it for a long time.
This allows for typing [8] instead of [8, 8, 8, 8] to specify the same
margin on all edges, for example. The constructors follow CSS' style of
specifying margins. The added constructors are:
- Margins(int all): Sets the same margin on all edges.
- Margins(int vertical, int horizontal): Sets the first argument to top
and bottom margins, and the second argument to left and right margins.
- Margins(int top, int vertical, int bottom): Sets the first argument to
the top margin, the second argument to the left and right margins,
and the third argument to the bottom margin.
Previously the argument order for Margins was (left, top, right,
bottom). To make it more familiar and closer to how CSS does it, the
argument order is now (top, right, bottom, left).
Although the chdir was set up for the applications opened from
the quick launch, the regular application list hadn't do this.
This meant that you could open a Terminal or HackStudio project
in the root directory, which isn't so bad, but it's better to stick
to the user home directory.
