56 | 16.1.1 Tkinter Modules</A> | |
57 | </H2> | |
58 | ||
59 | <P> | |
60 | Most of the time, the <tt class="module"><a href="module-Tkinter.html">Tkinter</a></tt> module is all you really | |
61 | need, but a number of additional modules are available as well. The | |
62 | Tk interface is located in a binary module named <tt class="module">_tkinter</tt>. | |
63 | This module contains the low-level interface to Tk, and should never | |
64 | be used directly by application programmers. It is usually a shared | |
65 | library (or DLL), but might in some cases be statically linked with | |
66 | the Python interpreter. | |
67 | ||
68 | <P> | |
69 | In addition to the Tk interface module, <tt class="module"><a href="module-Tkinter.html">Tkinter</a></tt> includes a | |
70 | number of Python modules. The two most important modules are the | |
71 | <tt class="module"><a href="module-Tkinter.html">Tkinter</a></tt> module itself, and a module called | |
72 | <tt class="module">Tkconstants</tt>. The former automatically imports the latter, so | |
73 | to use Tkinter, all you need to do is to import one module: | |
74 | ||
75 | <P> | |
76 | <div class="verbatim"><pre> | |
77 | import Tkinter | |
78 | </pre></div> | |
79 | ||
80 | <P> | |
81 | Or, more often: | |
82 | ||
83 | <P> | |
84 | <div class="verbatim"><pre> | |
85 | from Tkinter import * | |
86 | </pre></div> | |
87 | ||
88 | <P> | |
89 | <dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline"> | |
90 | <td><nobr><b><span class="typelabel">class</span> <tt id='l2h-4835' xml:id='l2h-4835' class="class">Tk</tt></b>(</nobr></td> | |
91 | <td><var>screenName=None, baseName=None, className='Tk', useTk=1</var>)</td></tr></table></dt> | |
92 | <dd> | |
93 | The <tt class="class">Tk</tt> class is instantiated without arguments. | |
94 | This creates a toplevel widget of Tk which usually is the main window | |
95 | of an application. Each instance has its own associated Tcl interpreter. | |
96 | ||
97 | <span class="versionnote">Changed in version 2.4: | |
98 | The <var>useTk</var> parameter was added.</span> | |
99 | ||
100 | </dl> | |
101 | ||
102 | <P> | |
103 | <dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline"> | |
104 | <td><nobr><b><tt id='l2h-4836' xml:id='l2h-4836' class="function">Tcl</tt></b>(</nobr></td> | |
105 | <td><var>screenName=None, baseName=None, className='Tk', useTk=0</var>)</td></tr></table></dt> | |
106 | <dd> | |
107 | The <tt class="function">Tcl</tt> function is a factory function which creates an object | |
108 | much like that created by the <tt class="class">Tk</tt> class, except that it does not | |
109 | initialize the Tk subsystem. This is most often useful when driving the Tcl | |
110 | interpreter in an environment where one doesn't want to create extraneous | |
111 | toplevel windows, or where one cannot (i.e. Unix/Linux systems without an X | |
112 | server). An object created by the <tt class="function">Tcl</tt> object can have a Toplevel | |
113 | window created (and the Tk subsystem initialized) by calling its | |
114 | <tt class="method">loadtk</tt> method. | |
115 | ||
