Subject: Key XFCNs V2.0

 

 
Key XFCNs V2.0 (replaces Key XFCNs V1.0 and the ControlKey XFCN) 
 
New in this version: 
   xfcns and xcmds for PowerMacs added. 
 
This HyperCard stack contains four XFCNs and one XCMD, all related to 
key events. 
 
The ControlKey XFCN, that came in a separate stack before, is now 
included in this file. 
 
controlKey() 
   returns "down" if the control key is pressed, "up" otherwise. 
 
keyIsDown (<virtual key code>|-1) 
   returns true if the specified key is pressed. With -1 as key code, 
the XFCN 
   returns true if at least one key ist pressed, false if no key is 
pressed. 
 
virtualKeyCode () 
   returns a comma delimited list of the virtual key codes of all 
currently 
   pressed keys. 
 
charKeyCode (["m[odifiers]"]) 
   returns the character of the currently pressed key. If "modifiers" is 
   specified, the function returns them too. If command-option-x is 
   pressed, the function returns the string "cmd opt x". 
 
flushKeyEvents 
   removes keyDown, keyUp, and autoKey events from the OS event queue. 
 
Requirements: 
   This stack needs at least System 7.1 and HyperCard 2.2
