<p>Display <em>text</em> in a message box, with a scrollbar and percentage
indication if <em>text</em> is too long to fit in a single “screen”.</p>
<p>An <code class="xref py py-meth docutils literal"><span class="pre">msgbox()</span></code> is very similar to a <a class="reference internal" href="#dialog.Dialog.yesno" title="dialog.Dialog.yesno"><code class="xref py py-meth docutils literal"><span class="pre">yesno()</span></code></a> box. The
only difference between an <code class="xref py py-meth docutils literal"><span class="pre">msgbox()</span></code> and a <code class="xref py py-meth docutils literal"><span class="pre">yesno()</span></code>
box is that the former only has a single <span class="guilabel">OK</span> button.
You can use <code class="xref py py-meth docutils literal"><span class="pre">msgbox()</span></code> to display any message you like.
After reading the message, the user can press the <code class="kbd docutils literal"><span class="pre">Enter</span></code>
key so that <strong class="program">dialog</strong> will exit and the calling program
can continue its operation.</p>
<p><code class="xref py py-meth docutils literal"><span class="pre">msgbox()</span></code> performs automatic line wrapping. If you want to
force a newline at some point, simply insert it in <em>text</em>. In
other words (with the default settings), newline characters in
<em>text</em> <strong>are</strong> respected; the line wrapping process performed by
<strong class="program">dialog</strong> only inserts <strong>additional</strong> newlines when
needed. If you want no automatic line wrapping, consider using
<a class="reference internal" href="#dialog.Dialog.scrollbox" title="dialog.Dialog.scrollbox"><code class="xref py py-meth docutils literal"><span class="pre">scrollbox()</span></code></a>.</p>

<p>A <code class="xref py py-meth docutils literal"><span class="pre">textbox()</span></code> lets you display the contents of a text file

can move through the file using the <code class="kbd docutils literal"><span class="pre">Up</span></code> and <code class="kbd docutils literal"><span class="pre">Down</span></code>
arrow keys, <code class="kbd docutils literal"><span class="pre">Page</span> <span class="pre">Up</span></code> and <code class="kbd docutils literal"><span class="pre">Page</span> <span class="pre">Down</span></code> as well as the
<code class="kbd docutils literal"><span class="pre">Home</span></code> and <code class="kbd docutils literal"><span class="pre">End</span></code> keys available on most keyboards. If
the lines are too long to be displayed in the box, the
<code class="kbd docutils literal"><span class="pre">Left</span></code> and <code class="kbd docutils literal"><span class="pre">Right</span></code> arrow keys can be used to scroll
the text region horizontally. For more convenience, forward and
backward search functions are also provided.</p>

<p>This method is a layer on top of <a class="reference internal" href="#dialog.Dialog.textbox" title="dialog.Dialog.textbox"><code class="xref py py-meth docutils literal"><span class="pre">textbox()</span></code></a>. The
<code class="xref py py-meth docutils literal"><span class="pre">textbox()</span></code> widget in <strong class="program">dialog</strong> allows one to
display file contents only. This method can be used to display
any text in a scrollable box. This is simply done by creating a
temporary file, calling <code class="xref py py-meth docutils literal"><span class="pre">textbox()</span></code> and deleting the
temporary file afterwards.</p>
<p>The text is not automatically wrapped. New lines in the
scrollable box will be placed exactly as in <em>text</em>. If you want
automatic line wrapping, you should use the <a class="reference internal" href="#dialog.Dialog.msgbox" title="dialog.Dialog.msgbox"><code class="xref py py-meth docutils literal"><span class="pre">msgbox()</span></code></a>

<li>if <em>init_contents</em> does not end with a newline character

<p>A <code class="xref py py-meth docutils literal"><span class="pre">mixedgauge()</span></code> box displays a list of “elements” with
status indication for each of them, followed by a text and
finally a global progress bar along the bottom of the box.</p>
<p>The top part (“elements”) is suitable for displaying a task
list. One element is displayed per line, with its <em>tag</em> part on
the left and its <em>item</em> part on the right. The <em>item</em> part is a
string that is displayed on the right of the same line.</p>
<p>The <em>item</em> part of an element can be an arbitrary string.
Special values listed in the <em class="manpage">dialog(3)</em> manual page
are translated into a status indication for the corresponding
task (<em>tag</em>), such as: “Succeeded”, “Failed”, “Passed”,
“Completed”, “Done”, “Skipped”, “In Progress”, “Checked”, “N/A”
or a progress bar.</p>
<p>A progress bar for an element is obtained by supplying a
negative number for the <em>item</em>. For instance, <code class="docutils literal"><span class="pre">"-75"</span></code> will
cause a progress bar indicating 75% to be displayed on the
corresponding line.</p>
<p>For your convenience, if an <em>item</em> appears to be an integer or a
float, it will be converted to a string before being passed to
the <strong class="program">dialog</strong>-like program.</p>
<p><em>text</em> is shown as a sort of caption between the list and the
global progress bar. The latter displays <em>percent</em> as the
percentage of completion.</p>
<p>Contrary to the regular <a class="reference internal" href="#gauge-widget"><span class="std std-ref">gauge widget</span></a>,
<code class="xref py py-meth docutils literal"><span class="pre">mixedgauge()</span></code> is completely static. You have to call
<code class="xref py py-meth docutils literal"><span class="pre">mixedgauge()</span></code> several times in order to display different
percentages in the global progress bar or various status
indicators for a given task.</p>

<p>Each menu entry consists of a <em>tag</em> string and an <em>item</em> string.
The <em class="dfn">tag</em> gives the entry a name to distinguish it from the
other entries in the menu and to provide quick keyboard access.
The <em class="dfn">item</em> is a short description of the option that the
entry represents.</p>
<p>The user can move between the menu entries by pressing the
<code class="kbd docutils literal"><span class="pre">Up</span></code> and <code class="kbd docutils literal"><span class="pre">Down</span></code> arrow keys, the first letter of the
tag as a hotkey, or the number keys <code class="kbd docutils literal"><span class="pre">1</span></code> through <code class="kbd docutils literal"><span class="pre">9</span></code>.

differences with the <a class="reference internal" href="#dialog.Dialog.menu" title="dialog.Dialog.menu"><code class="xref py py-meth docutils literal"><span class="pre">menu()</span></code></a> dialog box are:</p>
<blockquote>
<div><ul class="simple">
<li>entries are not automatically centered, but left-adjusted;</li>
<li>the current entry can be renamed by pressing the
<span class="guilabel">Rename</span> button, which allows editing the <em>item</em>
part of the current entry.</li>
</ul>
</div></blockquote>
<p>Each menu entry consists of a <em>tag</em> string and an <em>item</em> string.
The <em class="dfn">tag</em> gives the entry a name to distinguish it from the
other entries in the menu and to provide quick keyboard access.
The <em class="dfn">item</em> is a short description of the option that the
entry represents.</p>
<p>The user can move between the menu entries by pressing the
<code class="kbd docutils literal"><span class="pre">Up</span></code> and <code class="kbd docutils literal"><span class="pre">Down</span></code> arrow keys or the first letter of the
tag as a hot key. There are <em>menu_height</em> lines (not entries!)
displayed in the scrollable part of the menu at one time.</p>
<p>At the time of this writing (with <strong class="program">dialog</strong>
1.2-20140219), it is not possible to add an Extra button to this
widget, because internally, the <span class="guilabel">Rename</span> button <em>is</em>
the Extra button.</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p>It is strongly advised not to put any space in tags, otherwise
the <strong class="program">dialog</strong> output can be ambiguous if the
corresponding entry is renamed, causing pythondialog to return
a wrong tag string and new item text.</p>
<p class="last">The reason is that in this case, the <strong class="program">dialog</strong> output
is <code class="samp docutils literal"><span class="pre">RENAMED</span> <em><span class="pre">tag</span></em> <em><span class="pre">item</span></em></code> and pythondialog cannot guess

which will be displayed at row <em>yi</em>, column <em>xi</em> (row and column
numbers starting from 1).</p>
<p><em>field_length</em> and <em>input_length</em> are integers that respectively
specify the number of characters used for displaying the field

this field. These two integers also determine whether the
contents of the field can be modified, as follows:</p>

its contents determines the displayed length;</li>

length;</li>

<p>Display a dialog box containing <em>text</em> and two buttons labelled
<span class="guilabel">Yes</span> and <span class="guilabel">No</span> by default.</p>
<p>The box size is <em>height</em> rows by <em>width</em> columns. If <em>text</em> is
too long to fit in one line, it will be automatically divided
into multiple lines at appropriate places. <em>text</em> may also
contain the substring <code class="docutils literal"><span class="pre">"\n"</span></code> or newline characters to control
line breaking explicitly.</p>
<p>This <code class="xref py py-meth docutils literal"><span class="pre">yesno()</span></code> dialog box is useful for asking questions
that require the user to answer either “yes” or “no”. These are
the default button labels, however they can be freely set with
the <code class="docutils literal"><span class="pre">yes_label</span></code> and <code class="docutils literal"><span class="pre">no_label</span></code> keyword arguments. The user
can switch between the buttons by pressing the <code class="kbd docutils literal"><span class="pre">Tab</span></code> key.</p>
<p>Default values for the size parameters when the
<a class="reference internal" href="Dialog_class_overview.html#autowidgetsize"><span class="std std-ref">autowidgetsize</span></a> option is disabled:
<code class="docutils literal"><span class="pre">height=10,</span> <span class="pre">width=30</span></code>.</p>
<p>Notable exceptions:</p>
<blockquote>
<div>any exception raised by <a class="reference internal" href="internals.html#dialog.Dialog._perform" title="dialog.Dialog._perform"><code class="xref py py-meth docutils literal"><span class="pre">Dialog._perform()</span></code></a></div></blockquote>
