  57 <p class="p1">The GUI class provides a means of writing cross platform gui code. GUI provides Factory abstraction for all gui related core classes. Each gui kit is described by a gui scheme which maps class names to actual classes. These schemes are in turn used by <a href="ViewRedirect.html"><span class="s6">ViewRedirect</span></a> to provide a simple cross-platform gui syntax. It also provide utilities for switching kits and other cross platform tasks. You can get your available schemes (depending on what you installed) with:</p>
  58 <p class="p2"><br></p>
  59 <p class="p6"><span class="s7">GUI</span>.schemes;</p>
  60 <p class="p2"><br></p>
  61 <p class="p1">For a complete list of gui classes and redirects, see <a href="../GUI-Classes.html"><span class="s8">GUI-Classes</span></a>.</span></p>
  62 <p class="p5"><br></p>
  63 <p class="p7"><b>Switching and Referring to GUI Kits</b></p>
  64 <p class="p8"><br></p>
  65 <p class="p1">As of this writing, two GUI kits are available through the GUI class: CocoaGUI (Mac OS X native) and SwingGUI (Java) . Note that SwingOSC is not part of every SuperCollider distribution, so you may have to install it separately.</p>
  66 <p class="p2"><br></p>
  67 <p class="p1">You can switch the GUI kit by calling one of the following class methods:</p>
  68 <p class="p2"><br></p>
  69 <p class="p9"><span class="s9">GUI</span><span class="s3">.cocoa;<span class="Apple-tab-span">  </span></span>// use cocoa in subsequent GUI creation procedures</p>
  70 <p class="p9"><span class="s9">GUI</span><span class="s3">.swing;<span class="Apple-tab-span">  </span></span>// use swing in subsequent GUI creation procedures</p>
  71 <p class="p9"><span class="s3"><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span></span>// NOTE: If you do not have SwingOSC installed, you get</span></p>
  72 <p class="p9"><span class="s3"><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span></span>// a warning only, and do not switch; so you cannot</span></p>
  73 <p class="p9"><span class="s3"><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span></span>// accidentally disable your (mac) gui system.</p>
  74 <p class="p2"><span class="Apple-tab-span">     </span></p>
  75 <p class="p1">These methods return the new GUI kit implementation. The current implementation can be queried by calling</p>
  76 <p class="p2"><br></p>
  77 <p class="p9"><span class="s9">GUI</span><span class="s3">.current;<span class="Apple-tab-span">        </span></span>// returns the current GUI kit implementation</p>
  78 <p class="p2"><br></p>
  79 <p class="p1">If you want to make a GUI kit specific switch (e.g. in a class), then you should use the following instead, as on non-OSX systems the class CocoaGUI is not in the class library path, and you cannot check for an undefined class:</p>
  80 <p class="p2"><br></p>
  81 <p class="p9"><span class="s9">GUI</span><span class="s3">.id;<span class="Apple-tab-span">     </span></span>// returns the current GUI kit implementation id; this is currently either \cocoa or \swing</p>
  82 <p class="p2"><br></p>
  83 <p class="p1">For persistency, you can store the identifier of the kit implementation and recall the kit through the class method <span class="s10">fromID</span>:</p>
  84 <p class="p2"><br></p>
  85 <p class="p10">x = <span class="s9">GUI</span>.cocoa;</p>
  86 <p class="p9"><span class="s3">y = x.id;<span class="Apple-tab-span">   </span><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span></span>// store the identifier of a kit implementation</p>
  87 <p class="p9"><span class="s3">y.postln;<span class="Apple-tab-span">   </span><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span></span>// ; the id could be stored in a preferences file for example</p>
  88 <p class="p10"><span class="s9">GUI</span>.swing;</p>
  89 <p class="p9">// now switch back to the kit implementation with identifier y</p>
  90 <p class="p10"><span class="s9">GUI</span>.fromID( y );</p>
  91 <p class="p10"><span class="s9">GUI</span>.current.id.postln;<span class="Apple-tab-span">      </span><span class="s11">// --&gt; cocoa</span></p>
  92 <p class="p2"><br></p>
  93 <p class="p1">The <span class="s12">*use</span> and <span class="s12">*useID</span> methods allow you to temporarily switch the kit, so as to use it only for a dedicated block of statements:</p>
  94 <p class="p2"><br></p>
  95 <p class="p10"><span class="s9">GUI</span>.cocoa;</p>
  96 <p class="p10"><span class="s9">GUI</span>.useID( <span class="s13">\swing</span>, {<span class="s9">Array</span>.rand( 1000, 0.0, 1.0 ).plot });</p>
  97 <p class="p10"><span class="s9">GUI</span>.current.id.postln;<span class="Apple-tab-span">      </span><span class="s11">// --&gt; still cocoa</span></p>
  98 <p class="p11"><br></p>
  99 <p class="p1">You can get a particular kit using the <span class="s12">*get</span> method. You can switch to a particular kit using the <span class="s12">*set</span> method:</p>
 100 <p class="p2"><br></p>
 101 <p class="p9"><span class="s3">x = </span><span class="s9">GUI</span><span class="s3">.get( </span><span class="s13">\swing</span><span class="s3"> );<span class="Apple-tab-span">     </span></span>// note: unlike *swing and *cocoa, this does not _switch_ the current kit!</p>
 102 <p class="p10"><span class="s9">GUI</span>.current.id.postln;<span class="Apple-tab-span">      </span><span class="s11">// --&gt; still cocoa</span></p>
 103 <p class="p9"><span class="s9">GUI</span><span class="s3">.set( x );<span class="Apple-tab-span">       </span><span class="Apple-tab-span">    </span><span class="Apple-tab-span">    </span></span>// now we make SwingOSC the current kit</p>

 106 <p class="p7"><b>Extending GUI Kits</b></p>
 107 <p class="p8"><br></p>
 108 <p class="p1">GUI Kits can be extended with custom classes by using their respective <span class="s14">.put</span> methods:</p>
 109 <p class="p2"><br></p>
 110 <p class="p12"><span class="s9">GUI</span>.get( <span class="s13">\cocoa</span> ).put( <span class="s13">\myText</span>, <span class="s9">SCStaticText</span> );</p>
