SYNOPSIS
#include <agar/core.h> #include <agar/gui.h>
DESCRIPTION
The
AG_GlobalKeys interface associates application-wide keyboard shortcuts to specified
callback routines.
Note that AG_GlobalKeys entirely ignores the status of Agar windows and widgets. To implement keyboard operations specific to a given Agar window or widget, one would instead use AG_ActionOnKeyDown(3) or AG_ActionOnKeyUp(3). For a more low-level interface to keyboard processing, the base AG_Widget(3) class also provides the key-down and key-up event handlers.

INTERFACE ↑
void AG_BindGlobalKey (AG_KeySym key, AG_KeyMod mod, void (*fn)(void))
void AG_BindGlobalKeyEv (AG_KeySym key, AG_KeyMod mod, void (*fn)(AG_Event *))
void AG_BindStdGlobalKeys (void)
int AG_UnbindGlobalKey (AG_KeySym key, AG_KeyMod mod)
void AG_ClearGlobalKeys (void)
AG_BindGlobalKey() binds the specified routine to the given key combination. Keys are represented by AG_KeySym enums, and acceptable values for sym and mod arguments are listed under AG_KeySym(3) and AG_KeyMod(3).
The AG_BindGlobalKeyEv() variant accepts an AG_Event(3) style function. Note that arguments of AG_KEY_ANY and AG_KEYMOD_ANY are acceptable, in which case any key or key modifier will be matched.
The AG_BindStdGlobalKeys() routine sets up the standard key bindings:
| CTRL+EQUALS / META+EQUALS | AG_ZoomIn(3) |
| CTRL+MINUS / META+MINUS | AG_ZoomOut(3) |
| CTRL+0 / META+0 | AG_ZoomReset(3) |
| CTRL+Q / META+Q | AG_QuitGUI(3) |
| ESCAPE | AG_CloseFocusedWindow(3) |
AG_UnbindGlobalKey() removes the given key mapping. AG_ClearGlobalKeys() removes all existing key mappings.
