gen

<static> Object gen()

Generates HTML for showing the host sendkeys. The sendkey definition is the String Array lwh.keys.arr; from each entry a button will be generated:
• entry = name of a host key, e.g. "PF1"
  generates description = entry, and code for calling lw.send with this entry as host key name
• entry == ""
  is ignored (may be used at the end of a list)
• entry == "|"
  generates a line separator
• entry = " |" (or "html-text|")
  generates html text only (a "button separator")
• entry contains a "|" character, e.g. "HEX|lwv.bld.data(String.fromCharCode(parseInt(prompt('enter 2 hex digits'), 16)))"
  generates description from first part (here: "HEX") and code to eval the specified second part (here: code to send hex value to VT host)
  Note: do not forget to "escape" the JavaScript Strings, such as "Call2|lwv.key('\x1b2')", or 'Call3|lwv.key("\x1b3")'. The following is correct as well, but more complex: "Call4|lwv.key(\"\x1b4\")", or 'Call5|lwv.key(\'\x1b5\')'.
  Note: the specified text must be HTML encoded text, such as "&snbsp;" instead of SPACE " "

Returns:
false if no sendkeys available; else: true

type

<static> boolean type(<int> value)

Parameters:
value - optional:
if missing: simply returns the current type;
else: sets type: 0=top, 1=bottom, 2=left, 3=right

Returns:
the current toolbar type
