To prepare for translation support, this makes all of the widgets
cognizant of the language change event that occurs whenever
installTranslator() is called and automatically retranslates their text
where necessary.
This is important as calling the backing UI's retranslateUi() is often
not enough, particularly in cases where we add our own strings that
aren't controlled by it. In that case we need to manually refresh the
strings ourselves.
Enforces the use of the proper URL resolution functions. e.g.
url = some_local_path_string;
should actually be:
url = QUrl::fromLocalPath(some_local_path_string);
etc.
This makes it harder to cause bugs when operating with both strings and
URLs at the same time.
Other overloads of start() are considerably much safer to use if we ever
need this in the future and need to pass arguments to the program, given
it contains separate parameters for the program path and the arguments
themselves, whereas this unsafe overload contains both as a single
string.
Given the alternatives are much safer, we can disable this.
We can make this message more meaningful by indicating the location the
screenshot has been saved to. We can also log out whenever a screenshot
could not be saved (e.g. due to filesystem permissions or some other
reason).
Treating it as a u16 can result in a sign-conversion warning when
performing arithmetic with it, as u16 promotes to an int when aritmetic
is performed on it, not unsigned int.
This also makes the interface more uniform, as the layout interface now
operates on u32 across the board.
We can just pass a pointer to GMainWindow directly and make it a
requirement of the interface. This makes the interface a little safer,
since this would technically otherwise allow any random QWidget to be
the parent of a render window, downcasting it to GMainWindow (which is
undefined behavior).
Stays consistent in our code with using Qt's provided mechanisms, and
also properly handles Unicode paths (which file streams on Windows don't
do very well).
Qt uses a signed value to represent indices. We should follow this
convention where applicable to avoid unnecessary sign-conversion
warnings, as well as making it easier to interoperate with other aspects
of Qt.
While we're at it, we can also make a sign-conversion explicit.
critical() is intended for critical/fatal errors that threaten the
overall stability of an application. A user entering a conflicting key
sequence is neither of those.
1. This is something that should be solely emitted by the hotkey dialog
itself
2. This is functionally unused, given there's nothing listening for the
signal.
The previous code was all "smushed" together wasn't really grouped
together that well.
This spaces things out and separates them by relation to one another,
making it easier to visually parse the individual sections of code that
make up the constructor.
