We don't need to use a std::string here, given all that's done is
comparing the character sequence against another. This allows passing
regular const char* without needing to heap allocate.
Instead, we make a proper registry class and house it within the main
window, then pass it to whatever needs access to the loaded hotkeys.
This way, we avoid a global variable, and don't need to initialize a
std::map instance before the program can do anything.
These members don't need to be entirely exposed, we can instead expose
an API to operate on them without directly needing to mutate them
We can also guard against overflow/API misuse this way as well, given
active_sessions is an unsigned value.
The codec used by Qt for const char* and std::string don't necessarily
have to be the same depending on locale. Therefore, we should be using
the correct functions to do the conversions.
In OnMenuRecentFile() we don't need to construct a QFileInfo instance
just to check if a file exists, we can just use the static member
function to do that (which Qt's documentation also notes as quicker than
constructing an instance).
In UpdateUITheme(), we just want to try and open the file and check the
success of that operation. Technically speaking, between the existence
check and the open call, the file can be deleted or moved, but still
appear to succeed in code. i.e.
1. Existence check -> Returns true
2. File is moved/deleted
3. Open is called, the return value of which isn't checked
4. Nonsense behavior
This way we combine the existence check and the open into one.
Previously, when canceling out of the Load Folder dialog, a user would
get an error dialog about the selected folder not containing a main
file, however, by canceling out of the dialog, no selection was actually
made.
Gets rid of the need to hardcode the type in multiple places. This will
now be deduced automatically, based off the elements in the container
being provided to the algorithm.
Rather than having to type out the full std::map type signature, we can
just use a straightforward alias. While we're at it, rename
GetBreakpointList to GetBreakpointMap, which makes the name more
accurate. We can also get rid of unnecessary u64 static_casts, since
VAddr is an alias for a u64.
