Basic tooltips can be realized simply by using <a href="GtkWidget.html#gtk-widget-set-tooltip-text"><code class="function">gtk_widget_set_tooltip_text()</code></a>
145
or <a href="GtkWidget.html#gtk-widget-set-tooltip-markup"><code class="function">gtk_widget_set_tooltip_markup()</code></a> without any explicit tooltip object.

148
148
When you need a tooltip with a little more fancy contents, like
152
152
<div class="itemizedlist"><ul type="disc">
154
Set the <a href="GtkWidget.html#GtkWidget--has-tooltip"><span class="type">:has-tooltip</span></a> property to <a
155
href="/home/mclasen/gnome-2.18/install/share/gtk-doc/html/glib/glib-Standard-Macros.html#TRUE:CAPS"
154
Set the <a class="link" href="GtkWidget.html#GtkWidget--has-tooltip"><span class="type">"has-tooltip"</span></a> property to <a
155
href="../glib/glib-Standard-Macros.html#TRUE:CAPS"
156
156
><code class="literal">TRUE</code></a>, this will
157
157
make GTK+ monitor the widget for motion and related events
158
158
which are needed to determine when and where to show a tooltip.
161
Connect to the <a href="GtkWidget.html#GtkWidget-query-tooltip"><span class="type">::query-tooltip</span></a> signal. This signal
161
Connect to the <a class="link" href="GtkWidget.html#GtkWidget-query-tooltip"><span class="type">"query-tooltip"</span></a> signal. This signal
162
162
will be emitted when a tooltip is supposed to be shown. One
163
of the arguments passed to the signal handler is a <a href="GtkTooltip.html" title="GtkTooltip"><span class="type">GtkTooltip</span></a>
163
of the arguments passed to the signal handler is a <a class="link" href="GtkTooltip.html" title="GtkTooltip"><span class="type">GtkTooltip</span></a>
164
164
object. This is the object that we are about to display as a
165
165
tooltip, and can be manipulated in your callback using functions
166
like <a href="GtkTooltip.html#gtk-tooltip-set-icon"><code class="function">gtk_tooltip_set_icon()</code></a>. There are functions for setting
166
like <a class="link" href="GtkTooltip.html#gtk-tooltip-set-icon"><code class="function">gtk_tooltip_set_icon()</code></a>. There are functions for setting
167
167
the tooltip's markup, setting an image from a stock icon, or
168
168
even putting in a custom widget.

173
173
><code class="literal">TRUE</code></a> from your query-tooltip handler. This causes
174
174
the tooltip to be show. If you return <a
175
href="/home/mclasen/gnome-2.18/install/share/gtk-doc/html/glib/glib-Standard-Macros.html#FALSE:CAPS"
175
href="../glib/glib-Standard-Macros.html#FALSE:CAPS"
176
176
><code class="literal">FALSE</code></a>, it will not be shown.
182
182
In the probably rare case where you want to have even more control
183
183
over the tooltip that is about to be shown, you can set your own
184
<a href="GtkWindow.html" title="GtkWindow"><span class="type">GtkWindow</span></a> which will be used as tooltip window. This works as
184
<a class="link" href="GtkWindow.html" title="GtkWindow"><span class="type">GtkWindow</span></a> which will be used as tooltip window. This works as

Use <a class="link" href="GtkWidget.html#gtk-widget-set-tooltip-window"><code class="function">gtk_widget_set_tooltip_window()</code></a> to set a <a class="link" href="GtkWindow.html" title="GtkWindow"><span class="type">GtkWindow</span></a> created
194
194
by you as tooltip window.
197
197
In the ::query-tooltip callback you can access your window
198
using <a href="GtkWidget.html#gtk-widget-get-tooltip-window"><code class="function">gtk_widget_get_tooltip_window()</code></a> and manipulate as you
