Functions

addBinding void addBinding(BindingCode bc, InputBinding ib): Adds a single inputbinding to the inputhandler.
detectJoys void detectJoys(): Detects all connected joysticks.
expectAnyKeyEvent void expectAnyKeyEvent(): Enables an anykey event for once.
recordEvent void recordEvent(InputBinding code, bool delConflKeys, bool delConflCodes, bool cancelOnSysEsc, bool allowMouseEvents): Initializes event recording.
removeBinding void removeBinding(BindingCode bc, InputBinding ib): Removes a single inputbinding from the inputhandler.
removeJoy void removeJoy(int i): Removes info related to disconnected joysticks.
replaceLookupTree InputBindingLookupTree replaceLookupTree(InputBindingLookupTree newTree): Replaces the keycode lookup tree. Returns a copy of the current one as a backup.
startTextInput void startTextInput(TextInputListener listener, bool reportTextEditingEvents, Box textEditingArea): Starts text input handling.
stopTextInput void stopTextInput(): Stops text input handling.
test void test(): Tests for input.

Static functions

getSysEscKey BindingCode getSysEscKey(): Returns a default SysEsc binding.

Static variables

anykeyCode uint anykeyCode;: Code that is emmitted on an any key event.
sysescCode uint sysescCode;: Code that is emmitted on a system escape key (keyboard Esc key, joystick start button, etc) event.

Structs

JoyInfo struct JoyInfo: Contains data related to joysticks.

Variables

inputListener InputListener inputListener;: Passes all codes from keybindings to this interface. Multiple listeners at once are removed from newer versions to reduce overhead. Functionality can be restored with an event hub.
inputLookup InputBindingLookupTree inputLookup;: The main input lookup tree.
joyInfo JoyInfoMap joyInfo;: Contains info related to each joystick
joysticks JoyMap joysticks;: Contains pointers related to joystick handling
mouseListener MouseListener mouseListener;: Passes all mouse events to this interface. Multiple listeners at once are removed from newer versions to reduce overhead. Functionality can be restored with an event hub.
recordedCode InputBinding recordedCode;: The currently recorded code.
statusFlags uint statusFlags;: Contains info about the current status of the Input Handler. See the enum StatusFlags for more info.
systemEventListener SystemEventListener systemEventListener;: Passes all system events to this interface. Multiple listeners at once are removed from newer versions to reduce overhead. Functionality can be restored with an event hub.
textInputListener TextInputListener textInputListener;: Passes all text input events to this interface. Only a single listener should get text input at once.
