In StringUtil.h, the lambdas wrapping `Common::ToLower(char)` and `Common::ToUpper(char)` were only necessary due to the function names being overloaded.
This lets us reduce the number of USE_RETRO_ACHIEVEMENTS ifdefs in the
code base, reducing visual clutter. In particular, needing an ifdef for
each call to IsHardcodeModeActive was annoying to me. This also reduces
the risk that someone writes code that accidentally fails to compile
with USE_RETRO_ACHIEVEMENTS disabled.
We could cut down on ifdefs even further by making HardcodeWarningWidget
always exist, but that would result in non-trivial code ending up in the
binary even with USE_RETRO_ACHIEVEMENTS disabled, so I'm leaving it out
of this PR. It's not a lot of code though, so I might end up revisiting
it at some point.
Bugfix for hardcore-disabled items being disabled when hardcore was true but achievement integration was false, which should mean hardcore is effectively disabled. Now everything checks the IsHardcoreModeActive method in AchievementManager which processes the setting AND the game state to determine if hardcore mode is actually active.
Debug Mode gives players direct read and write access to memory, which could be used to completely manipulate RetroAchievements logic and therefore is not allowed in hardcore mode.
This makes it so that if you just want to reload the current style (eg. on program start, or in response to a system event), you don't need to know the name of the currently selected user style. It's also more consistent with the way the 'userstyle/enabled' flag works.
See https://bugs.dolphin-emu.org/issues/13232; this was introduced in 7dde0c3c31. Apparently, providing a parent for a widget that is not visible makes your new widget visible when the parent is later made visible, in addition to managing the deletion of the widget; the documentation does not specify this (only that if the parent is visible you need to explicitly show it).
The m_checkbox_lock_mouse QCheckBox was only conditionally being added
to the layout, leaving it unmanaged and leaking
Setting the parent will allow it to be managed.
