The vector is only ever queryied and it's contents aren't modified, so
there's no reason to take the vector by value. We can take a constant
reference to it to avoid unnecessary allocating.
In these cases, the given string is only ever compared against other
string, so std::string can be turned into a std::string_view to allow
non-allocating inputs.
If opening the adapter fails, report the libusb error message in the GUI
instead of “No Adapter Detected”.
The error condition is removed when the adapter is unplugged.
* Simplifies libusb context usage and allows us to set options for
all contexts easily. Notably, this lets us enable usbdk support
in libusb, which is now opt-in in the latest version.
* Moves the libusb config descriptor wrapper class to LibusbUtils too
since that could easily be reused.
* Moves device listing to LibusbUtils too and add a lock around it
as some libusb backends are not thread safe.
* Consequences: only a single context and a single event handling
thread is used now, which is more efficient.
This is useful in far out-of-calibration controllers, such as the
Switch Pro controller. This also adds support for configuring the center
in the Mapping widget.
Android doesn't report values for the inputs generated by FullAnalogInput so
there isn't a reason to add them as such. This also avoids a bug(for android)
where if there are three inputs(say 12, 11, and 121), and you generate a FullAnalogInput
with 12/11 then it will create another input with the name 121 which can cause conficts
with the real 121 input. This is probably not an issue on PC since most Axis inputs
are named and not numbered.
Previously, the Qt frontend would initialize the controller
interface on starting, resulting in the cursor position being
relative to the main window, instead of the render window.
Xlib supports many mouse buttons, though there are 9 standard buttons, and they aren't arranged like other mouse APIs. Using only 5 buttons was preventing the use of buttons besides left/right/middle click and the scroll wheel. Here's what all the standard buttons are:
1. left button
2. middle button (pressing the scroll wheel)
3. right button
4. turn scroll wheel up
5. turn scroll wheel down
6. push scroll wheel left
7. push scroll wheel right
8. 4th button (aka browser backward button)
9. 5th button (aka browser forward button)
The remaining button indices are non-standard and device-specific, and technically far more than 32 are supported, but this seems like a reasonable limit to avoid cluttering the list with tons of useless mouse buttons. What mouse has more than 32 buttons anyways?
Makes it less error-prone to get state data from analog sticks (no need
to pass any locals), and also allows direct assignment, letting the
retrieved data be const.

Deduplicates code, and gets rid of some problems the old code had
(such as: bad performance when calling native functions, only one
disc showing up for multi-disc games, Wii banners being low-res,
unnecessarily much effort being needed for adding more metadata).
Some button names should be translated, for instance Up, Left and such.
At the same time, some other button names shouldn't be translated,
for reasons that might be less obvious. In 0146456af, I removed the
_trans markers for button names that never need to be translated
(such as A and B), but that isn't actually enough to ensure that
DolphinWX won't try to translate them anyway. This commit adds a bool
that explicitly tells the GUI whether a button name should be translated.
Otherwise we'll have problems like the GUI treating the button name "B"
(which isn't supposed to be translated) as matching the translatable
string "B" (being an abbreviation of "bytes"), meaning that the button
"B" will be labeled "o" when running Dolphin in French (after
translations get pulled from Transifex the next time).
By the way, while it turned out that DolphinWX translated all button
names, it also turned out that DolphinQt2 translated *no* button names.
Go figure. This commit makes them consistent with each other.
Makes our libraries explicitly link in which libraries they need.
This makes our dependencies explicit and removes the reliance on the
LIBS variable to contain the libraries that they need.
Whenever udev_monitor_receive_device() returns a non-null pointer,
the device must be unref'd after use with udev_device_unref().
We previously missed some unref calls for non-evdev devices.
It's not guaranteed that the eventfd is smaller than the monitor fd,
because fds are not always monotonically allocated. To select()
correctly in all cases, use the max between the monitor fd and eventfd.
This lets Dolphin know if a configured GameCube Controller should actually
be treated as connected or not.
Talked to @JMC47 a bit about this last night. My use-case is that all of
my controllers are the same hardware (Xbox One controllers) so share the
same configuration (modulo device number). Treating them all as always
connected isn't a problem for most games, but in some (Smash Bros.) it
forces me to go find a keyboard/mouse and unconfigure any controllers
that I don't actually have connected. Hotplugging devices (works on macOS,
at least) + this patch remove my need to ever touch the Controller Config
dialog while in a game.
This patch makes the following changes:
- A new `BooleanSetting` in `GCPadEmu` called "Always Connected", which
defaults to false.
- `ControllerEmu` tracks whether the default device is connected on every
call to `UpdateReferences()`.
- `GCPadEmu.GetStatus()` now sets err bit to `PAD_ERR_NO_CONTROLLER` if
the default device isn't connected.
- `SIDevice_GCController` handles `PAD_ERR_NO_CONTROLLER` by imitating the
behaviour of `SIDevice_Null` (as far as I can tell, this is the only use
of the error bit from `GCPadStatus`).
I wanted to add an OSD message akin to the ones when Wiimotes get
connected/disconnected, but I haven't yet found where to put the logic.
Axis range was previously calculated as max + abs(min), which relies on the assumption that
min will not exceed 0. For (min, max) values like (0, 255) or (-128, 127), which I assume to
be the most common cases, the range is correctly calculated as 255. However, given (20,
235), the range is erroneously calculated as 255, leading to axis values being normalized
incorrectly.
SDL already handles this case correctly. After changing the range calculation to max - min,
the axis values received from the evdev backend are practically identical to the values
received from the SDL backend.
