TQt provides many useful features -that we can begin using immediately. Some of the most interesting -ones are presented below as a guide for where to start extending your -existing projects. -<p> <h2> Using Unicode -</h2> -<a name="1"></a><p> Support for <a href="i18n.html">internationalization</a> is very easy -with TQt. Using <a href="tqstring.html">TQString</a> instead of <tt>char*</tt> for storing text gives -us support for most of the written languages around the world. Our <tt>Page</tt> and <tt>Options</tt> structs look much simpler now. -<p> - -<p> <pre></pre> -<p> <pre></pre> -<p> All functions that use the <tt>Page</tt> and <tt>Options</tt> structs need to be -updated to use TQString properly. Since TQString is also an <a href="shclass.html#implicitly-shared">implicitly shared</a> class, we no longer have to do any memory management with our -strings. We can remove all occurences of the <a href="tqcstring.html#qstrdup">tqstrdup</a>() function, -and we never need to use <em>new</em> or <em>delete</em> when done with a string. -TQString will allocate and delete data when needed. -<p> Here are the <tt>MainWindow::fileOpen()</tt> and <tt>MainWindow::pageChange()</tt> -functions from <tt>mainwindow.ui.h</tt>. Notice that the code no longer -uses <em>delete</em> or <a href="tqcstring.html#qstrdup">tqstrdup</a>() when storing text. -<p> - -<p> <pre></pre> -<p> <pre> - ... -</pre> - -<p> <pre></pre> -<p> Almost all of the functions in our application are affected by this -change. In most cases, we end up removing more code than we are -adding. To keep the size of this walkthrough reasonable, we've only -shown a small portion of the required changes, since the changes are -very similar to those shown above. -<p> <h2> Writing Platform-Independent Code -</h2> -<a name="2"></a><p> TQt provides many <a href="io.html">input and output</a> classes. We -can use these in <tt>MainWindow::readDB()</tt> and <tt>MainWindow::saveDB()</tt>. -Currently, these functions use functions only found on UNIX machines. -Using <a href="tqfile.html">TQFile</a> and <a href="tqtextstream.html">TQTextStream</a> removes this dependency on UNIX, and we can -begin building and testing our application on Microsoft Windows and -Apple Mac OS X. -<p> The platform-independent versions of the <tt>MainWindow::readDB()</tt> and -<tt>MainWindow::saveDB()</tt> functions can be found in the <tt>io.cpp</tt> file. -<p> <h2> Designing a Modern User Interface -</h2> -<a name="3"></a><p> Since we used the <em>TQt Designer</em> to design the <em>Main Window</em> -widget, we can extend the interface easily. We can use some of the -more advanced features of <a href="tqmainwindow.html">TQMainWindow</a>, which includes dockable -toolbars. Adding these is simple with the <em>TQt Designer</em>. The -final version of our project includes a toolbar, which provides quick -access to the <em>Open</em>, <em>Save</em>, <em>Print</em>, <em>New Page</em> and <em>Delete to Trash</em> actions. -<p> The possibilities are endless. An <em>Edit</em> menu, with the common <em>Cut</em>, <em>Copy</em> and <em>Paste</em> actions, could be added in a relatively -short period of time. -<p> [ <a href="motif-walkthrough-9.html">Previous: Replacing the Print Dialog</a> ] -[ <a href="motif-walkthrough.html">Home</a> ] -<p> -<!-- eof --> -<p><address><hr><div align=center> -<table width=100% cellspacing=0 border=0><tr> -<td>Copyright © 2007 -<a href="troll.html">Trolltech</a><td align=center><a href="trademarks.html">Trademarks</a> -<td align=right><div align=right>TQt 3.3.8</div> -</table></div></address></body> -</html> |
