<p>
This is the prototype for all functions you pass as <em class="parameter"><code>help_func</code></em> to the
various GIMP dialog constructors like <a class="link" href="GimpDialog.html#gimp-dialog-new"><code class="function">gimp_dialog_new()</code></a>,
<a class="link" href="libgimpwidgets-GimpQueryBox.html#gimp-query-int-box"><code class="function">gimp_query_int_box()</code></a> etc.
</p>
<p>
Help IDs are textual identifiers the help system uses to figure which
page to display.
</p>
<p>
All these dialog constructors functions call <a class="link" href="libgimpwidgets-GimpHelpUI.html#gimp-help-connect"><code class="function">gimp_help_connect()</code></a>.
</p>
<p>
In most cases it will be ok to use <a class="link" href="libgimpwidgets-GimpHelpUI.html#gimp-standard-help-func"><code class="function">gimp_standard_help_func()</code></a> which does
nothing but passing the <em class="parameter"><code>help_id</code></em> string to <a
href="../app/app-Gimp-gui.html#gimp-help"
><code class="function">gimp_help()</code></a>. If your
plug-in needs some more sophisticated help handling you can provide
your own <em class="parameter"><code>help_func</code></em> which has to call <a
href="../app/app-Gimp-gui.html#gimp-help"
><code class="function">gimp_help()</code></a> to actually display
the help.

The reason why we don't use <a

<p>
This function can be called with <a

if you want to set a help link for a widget which shouldn't have

This function invokes the context help inspector.

<p>
The mouse cursor will turn turn into a question mark and the user can
click on any widget of the application which started the inspector.

<p>
If the widget the user clicked on has a <em class="parameter"><code>help_id</code></em> string attached
(see <a class="link" href="libgimpwidgets-GimpHelpUI.html#gimp-help-set-help-data"><code class="function">gimp_help_set_help_data()</code></a>), the corresponding help page will
be displayed. Otherwise the help system will ascend the widget hierarchy
until it finds an attached <em class="parameter"><code>help_id</code></em> string (which should be the
case at least for every window/dialog).</p>
