// ---Input Handling---
|
||||
// This code is a mess, specifically because Android is so so SO inconsistent with how it handles the keyboard
|
||||
// Some keyboards dispatch key events, some directly append text, and none of them meet the most basic standards supported by most other devices
|
||||
// This mess is my attempt at dealing with that, and it will most likely only ever be triggered by Android
|
||||
//
|
||||
// It has three main modes.
|
||||
// 1) Standard keyboard mode:
|
||||
// This mode keeps the hiddenInput empty, saves the last key press, and on every keypress checks if it the keys are being pressed incorrectly.
|
||||
// If there is a problem, it switches to compatibility mode, using beforeinput and input events instead of keydown and keyup
|
||||
// 2) Compatibility mode:
|
||||
// This most is most likely going to be used by Android, because Android only every dispatches keyCode 229 for any keypress
|
||||
// When we enter this mode, we grab the last known key press and redispatch it, and programatically dispatch key events by reading e.inputType and e.data from beforeinput
|
||||
// Unfortunately, Android is weird with this as well. Sometimes it only dispatches insertCompositionText events, and sometimes it gives the correct inputTypes as well
|
||||
// Additionally, programmatically setting the input's text contents (BECAUSE ANDROID IGNORES PREVENTDEFAULT AGHHHHH) dispatches a repeat of the previous event
|
||||
// Luckily, we can check if this happens when we first create the input, which necessitates the third mode:
|
||||
// 3) Duplicate mode:
|
||||
// If we are getting duplicate inputs, this mode ignores every other input if it matches the state saved in clientWindow.previousKey
|
||||
// If users make it to this mode and still are having issues, it may be best just to remove support for their device
