some weird combination of scrolling/nesting hyprland and closing a
window i managed to divide by zero here, reported by ubsan. add a check
to ensure we dont hit UB.
* Discrete scrolling round away from zero
e.deltaDiscrete can be multiples of 30 instead of the usual 120 causing
the rounded value to be 0 when too small causing erratic scrolling.
* Send value120 alongside discrete
Fixes sensitivity issues for clients that support value120 axis events
moves std::shared_ptrs to a new implementation
Advantages:
- you can dereference a weak_ptr directly. This will obviously segfault on a nullptr deref if it's expired.
- this is useful to avoid the .lock() hell where we are 100% sure the pointer _should_ be valid. (and if it isn't, it should throw.)
- weak_ptrs are still valid while the SP is being destroyed.
- reasoning: while an object (e.g. CWindow) is being destroyed, its `weak_ptr self` should be accessible (the sp is still alive, and so is CWindow), but it's not because by stl it's already expired (to prevent resurrection)
- this impl solves it differently. w_p is expired, but can still be dereferenced and used. Creating `s_p`s is not possible anymore, though.
- this is useful in destructors and callbacks.
Implements an intermediary HID class for mice, keyboards and touch devices, removing the old structs from WLClasses.hpp
Yes, virtual ones are duplicated a bit, but will likely be de-duped once wlr_input_device is not used anymore.
* inputmgr: dont double free on hotplug
since we are also unrefing the state on hotplugging the keyboard set the
state to nullptr so the destructor if case actually catches its been
already freed.
* keybindgmgr: dont double free on layout switching
d5bf153 added keymap unref at the end of updateXKBTranslationState to
not leak it when exiting, only it causes updateXKBTranslationState to
double free when changing layouts. since its already freed. remove the
unneeded extra xkb_keymap_unref.
`lastBoxLocal`'s size should be the actual popup's size instead of the cursor
rectangle's size. Also, the rectangle position is now relative to the popup.
(Actually fixes#5255 imho.)
One thing #3922 missed was handling focus held by buttons. Let's hope I get
it right this time.
