editor)</h1>
<h2 id="how-to-compile-and-execute-the-text-editor-tfe.">How to compile
and execute the text editor ‘tfe’.</h2>
<p>First, source files are in the <a
href="https://github.com/ToshioCP/Gtk4-tutorial">Gtk4-tutorila
repository</a>. How to download them is written at the end of the <a
href="sec15.html">previous section</a>.</p>
<p>The following is the instruction of compilation and execution.</p>
<ul>
<li>You need meson and ninja.</li>
<li>If you have installed gtk4 from the source, you need to set
environment variables to suit your installation.</li>
<li>Change your current directory to <code>src/tfe5</code>
directory.</li>
<li>Type <code>meson setup _build</code> for configuration.</li>
<li>Type <code>ninja -C _build</code> for compilation. Then the
application <code>tfe</code> is built under the <code>_build</code>
directory.</li>
<li>Type <code>_build/tfe</code> to execute it.</li>
</ul>
<p>Then the window appears. There are four buttons, <code>New</code>,
<code>Open</code>, <code>Save</code> and <code>Close</code>.</p>
<ul>
<li>Click on <code>Open</code> button, then a file chooser dialog
appears. Choose a file in the list and click on <code>Open</code>
button. Then the file is read and a new Notebook Page appears.</li>
<li>Edit the file and click on <code>Save</code> button, then the text
is saved to the original file.</li>
<li>Click <code>Close</code>, then the Notebook Page disappears.</li>
<li>Click <code>Close</code> again, then the <code>Untitled</code>
Notebook Page disappears and at the same time the application
quits.</li>
</ul>
<p>This is a very simple editor. It is a good practice for you to add
more features.</p>
