ResourceGraph and Network applets now open their SystemMonitor tab
|
|
Since we now commit memory that isn't actually yet allocated, it is
no longer available to other applications. So it is effectively
allocated.
|
|
This makes SystemMonitor a bit more pleasant to look at. :^)
|
|
This makes it more likely to be able to get statistics when resources
are scarce.
|
|
|
|
Rather than crashing with an ASSERT, when we can't read from /proc
we draw the graph with red instead. This also alerts the user that
memory is very low.
|
|
* Fix by only activating the deletion action if we have a selection
|
|
When we have an abstract font class it makes no sense to keep
these methods in the Font class.
|
|
This matches other similar hook names.

This patch removes size policies and preferred sizes, and replaces them
with min-size and max-size for each widget.
Box layout now works in 3 passes:
1) Set all items (widgets/spacers) to their min-size
2) Distribute remaining space evenly, respecting max-size
3) Place widgets one after the other, adding spacing in between
I've also added convenience helpers for setting a fixed size (which is
the same as setting min-size and max-size to the same value.)
This significantly reduces the verbosity of widget layout and makes GML
a bit more pleasant to write, too. :^)

This implements a number of changes related to time:
* If a HPET is present, it is now used only as a system timer, unless
the Local APIC timer is used (in which case the HPET timer will not
trigger any interrupts at all).
* If a HPET is present, the current time can now be as accurate as the
chip can be, independently from the system timer. We now query the
HPET main counter for the current time in CPU #0's system timer
interrupt, and use that as a base line. If a high precision time is
queried, that base line is used in combination with quering the HPET
timer directly, which should give a much more accurate time stamp at
the expense of more overhead. For faster time stamps, the more coarse
value based on the last interrupt will be returned. This also means
that any missed interrupts should not cause the time to drift.
* The default system interrupt rate is reduced to about 250 per second.
* Fix calculation of Thread CPU usage by using the amount of ticks they
used rather than the number of times a context switch happened.
* Implement CLOCK_REALTIME_COARSE and CLOCK_MONOTONIC_COARSE and use it
for most cases where precise timestamps are not needed.

It's just more attack surface, and can be deduced from the format anyway.

Prevents the adding of items to the ClipboardHistoryModel if the raw
data and mime_type of the item being added is the same as another item
already in the list.

All of these files were getting ByteBuffer.h from someone else and then
using it. Let's include it explicitly.

Fixes #4031.

The volume slider was linear, which is not ideal for an audio volume
control. Perceived volume would not change much within 30-100% range
and would change in leaps within 0-30% range where the resolution is
not sufficient for fine grained control.
The simplest solution is to bring the value into 0.0-1.0 range and
square it to obtain an exponential curve. This is a decent
approximation of the logarithmic taper used in audio potentiometers.

The calculation was only taking the rect's inner height, but not its top
offset into account.
Fixes #3540.

Now that we can copy bitmaps, we need some kind of cap here or memory
usage quickly skyrockets.
This could probably be improved or made adaptive somehow, this is just
a simple hard cap for now.

To open up for putting not just text/plain content on the clipboard,
let's make the GUI::Clipboard API a bit more raw-data-friendly. :^)
|
|
Drops the '16' suffix from filenames. Resizes inconsistent
audio-volume icons to intended size.
|
|
|
|
Part of the graph was hidden under the frame rect, which had the effect
of delaying the appearance of spikes (well, all changes really.)
|

This is preparation for using ModelRole in the ModelIndex API.
|
|
The SI prefixes "k", "M", "G" mean "10^3", "10^6", "10^9".
The IEC prefixes "Ki", "Mi", "Gi" mean "2^10", "2^20", "2^30".
Let's use the correct name, at least in code.
Only changes the name of the constants, no other behavior change.

The tooltip doesn't update while it's visible.

Adds a classic volume slider to the AudioApplet. Percent text
and mute state can now be toggled via checkboxes. Left click opens,
right click mutes. Updates existing icons and adds unique icons for
muted vs zero volume states.
|
|
"Image" was a bit too vague, "ImageWidget" is obviously a widget of
some sort.
|
|
|
|
The Audio applet now dislays the main mix volume next to the speaker
icon. A click on the applet still mutes the global mixer. By scrolling
the mouse wheel while on the applet, you can decrease/increase the mixer
volume. Different icons will be painted depending on the volume and the
mute state.
Happy listening :^)

Having this on the stack makes whole-program teardown iffy. Turning it
into a Core::Object allows anyone who needs it to extends its lifetime.
|
|
It's less code, and it's potentially more efficient once
posix_spawn is a real syscall.

- Parsing invalid JSON no longer asserts
Instead of asserting when coming across malformed JSON,
JsonParser::parse now returns an Optional<JsonValue>.
- Disallow trailing commas in JSON objects and arrays
- No longer parse 'undefined', as that is a purely JS thing
- No longer allow non-whitespace after anything consumed by the initial
parse() call. Examples of things that were valid and no longer are:
- undefineddfz
- {"foo": 1}abcd
- [1,2,3]4
- JsonObject.for_each_member now iterates in original insertion order

Auto-sizing of view columns is now enabled by default. This removes the
last remaining need for ColumnMetadata, so this patch gets rid of it.
