This project has a single custom dialog: the <em>Page Edit</em> +dialog. +<p> Instead of writing the code ourselves, we use <a href="designer-manual.html">TQt Designer</a> to design our dialog. +Designing a custom dialog is beyond the scope of +this document: see the <a href="designer-manual.html">TQt Designer Manual</a> if you're unfamiliar +with TQt's visual design tool. +<p> <h2> Replacing the <em>Page Edit</em> Dialog +</h2> +<a name="1"></a><p> The custom <a href="qdialog.html">TQDialog</a> description for the <em>Page Edit</em> dialog is saved +as <tt>pageeditdialog.ui</tt>. We add this file to the project file by +adding the line +<pre> +FORMS = pageeditdialog.ui +</pre> + +to the <tt>.pro</tt> file, and regenerate the <tt>Makefile</tt>. The <em>uic</em> +utility generates the code for our custom TQDialog, which is then +compiled and linked into our application. (<em>uic</em> is invoked +automatically from makefiles generated from <tt>.pro</tt> files.) +<p> We need to pass the top-level <a href="qmotifwidget.html">TQMotifWidget</a> as the <em>client_data</em> +argument to the <tt>EditPage</tt> function, which we will use as the parent +for our new <tt>PageEditDialog</tt>. We do this the same way as we have +done for the <em>Open</em> and <em>Save As</em> dialogs in <tt>todo.cpp</tt>. +<p> + +<p> <pre></pre> +<p> The <tt>EditPage()</tt> function is implemented in <tt>actions.cpp</tt>. We start +by adding the includes needed for the <tt>PageEditDialog</tt> and <a href="qlineedit.html">TQLineEdit</a>. +<p> + +<p> <pre></pre> +<p> In the <tt>EditPage()</tt> function, We create the <tt>PageEditDialog</tt>, set +the initial values of the three TQLineEdit widgets with values from the +current page and execute the dialog. +<p> <pre></pre><pre> + ... +</pre> + +<p> At this point in the code, the page properties should be modified. The +code to do this is in the <tt>DoEditPage()</tt> function. We move the +contents of <tt>DoEditPage()</tt> to this point and remove the <tt>DoEditPage()</tt> function completely. +<p> The <tt>Page</tt> struct defined in <tt>page.h</tt> stores strings in <tt>char*</tt> +arrays. Since the PageEditDialog and the data it contains will be +destroyed when we return from this function, we need to convert the +unicode <a href="qstring.html">TQString</a> data into a <a href="qcstring.html">TQCString</a> in the local encoding and +duplicate it with <a href="qcstring.html#qstrdup">qstrdup</a>(). +<p> <pre></pre> +<p> The same process must be done for the minorTab text: +<p> <pre></pre> +<p> ... and for the majorTab text: +<p> <pre></pre> +<p> [ <a href="motif-walkthrough-3.html">Previous: Using TQt Standard Dialogs</a> ] +[ <a href="motif-walkthrough.html">Home</a> ] +[ <a href="motif-walkthrough-5.html">Next: Using Existing Dialogs with TQMotifDialog</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> |
