In Tkinter, options are specified as keyword-arguments in the instance constructor, and keyword-args for configure calls or as instance indices, in dictionary style, for established instances. See section <A href="tkinter-setting-options.html#tkinter-setting-options">16.1.6</A> on setting options. <P> <dl><dd><pre class="verbatim"> button .fred -fg red =====> fred = Button(panel, fg = "red") .fred configure -fg red =====> fred["fg"] = red OR ==> fred.config(fg = "red") </pre></dl> <P> In Tk, to perform an action on a widget, use the widget name as a command, and follow it with an action name, possibly with arguments (options). In Tkinter, you call methods on the class instance to invoke actions on the widget. The actions (methods) that a given widget can perform are listed in the Tkinter.py module. <P> <dl><dd><pre class="verbatim"> .fred invoke =====> fred.invoke() </pre></dl> <P> To give a widget to the packer (geometry manager), you call pack with optional arguments. In Tkinter, the Pack class holds all this functionality, and the various forms of the pack command are implemented as methods. All widgets in <tt class="module"><a href="module-Tkinter.html">Tkinter</a></tt> are subclassed from the Packer, and so inherit all the packing methods. See the <tt class="module"><a href="module-Tix.html">Tix</a></tt> module documentation for additional information on the Form geometry manager. <P> <dl><dd><pre class="verbatim"> pack .fred -side left =====> fred.pack(side = "left") </pre></dl> <P> <DIV CLASS="navigation"> <p><hr> <table align="center" width="100%" cellpadding="0" cellspacing="2"> <tr> <td><A HREF="node504.html"><img src="../icons/previous.gif" border="0" height="32" alt="Previous Page" width="32"></A></td> <td><A href="module-Tkinter.html"><img src="../icons/up.gif" border="0" height="32" alt="Up One Level" width="32"></A></td> <td><A HREF="node506.html"><img src="../icons/next.gif" border="0" height="32" alt="Next Page" width="32"></A></td> <td align="center" width="100%">Python Library Reference</td> <td><A href="contents.html"><img src="../icons/contents.gif" border="0" height="32" alt="Contents" width="32"></A></td> <td><a href="modindex.html" title="Module Index"><img src="../icons/modules.gif" border="0" height="32" alt="Module Index" width="32"></a></td> <td><A href="genindex.html"><img src="../icons/index.gif" border="0" height="32" alt="Index" width="32"></A></td> </tr></table> <b class="navlabel">Previous:</b> <a class="sectref" HREF="node504.html">16.1.3 A (Very) Quick</A> <b class="navlabel">Up:</b> <a class="sectref" href="module-Tkinter.html">16.1 Tkinter </A> <b class="navlabel">Next:</b> <a class="sectref" HREF="node506.html">16.1.5 How Tk and</A> <hr> <span class="release-info">Release 2.2, documentation updated on December 21, 2001.</span> </DIV> <!--End of Navigation Panel--> <ADDRESS> See <i><a href="about.html">About this document...</a></i> for information on suggesting changes. </ADDRESS> </BODY> </HTML>
