#X text 27 18 REACTING TO USER INPUT;
#X text 41 49 Most \, if not all \, programming environments provide
us with tools to capture 'user initiated' events from the operating
system. Keyboard input \, mouse clicks \, and mouse movements are the
most common events in this 'user event' category.;
#X text 41 125 Pd's [key] \, [keyup] \, and [keyname] are complimented
by the externals such as [gemmouse] and [nimouse] to provide us with
a full range of tools to gleen a user's activities at the computer.
;
#X text 42 201 It's interesting to note that \, with these tools \,
PD can mimic some of the functions in other languages - Javascript
for example has:;
#X text 55 272 onKeyUp;
#X text 55 253 onKeyDown;
#X text 55 291 onKeyPress;
#X text 42 322 hmmm...wouldn't it be great if Pd also gave us onChange
\, onBlur \, onFocus \, onClick \, onDblClick \, onDragDrop \, onLoad
\, onMouseDown \, onMouseOver \, onMouseOut \, onMouseMove \, onUnload...?

#X text 88 208 Also note that key combinations \, such as SHIFT+7 produce
a different result than SHIFT or 7 alone.;
#X text 88 323 The [key] and [keyup] objects can mimic the functionality
of the [noteon] and [noteoff] objects. A key combination such as SHIFT+7
could be considered a 'chord'!;
#X text 89 54 The number at this outlet represents the numeric "ID"
of a key on the computer's keyboard. This event occurs when the key
is pressed down. Only one event is captured at a time.;
#X text 88 267 The number at this outlets represents the numeric "ID"
of a key on the computer's keyboard. This even occurs when the key
is released. Only one event is captured at a time.;
#X text 89 119 Some keys \, such as SHIFT or the F1-F12 series all
produce a zero \, but we can see by the [bng] that the event is not
ignored completely...but the numeric "ID" of the key is not captured
successfully. (This may produce different results on different systems.)

events. The left inlet produces a 1 when a key goes down \, and a zero
when the key goes up. The right outlet produces a symbol which represents
the name of the key.;

#X text 110 291 [key] and [keyup] report the (system dependent) numbers
of "printing" keys of the keyboard. [keyname] gives the symbolic name
of the key \, with a 1 if it's up or 0 if it's down \, and works with
non-printing keys like shift or "F1".;
#X text 111 362 Caveat -- this only works if Pd actually gets the key
events which can depend on the stacking order of windows and/or the
pointer location. This is dependent on the system.;
