Hi,<br><br>I'm porting an app to Maemo and I came to a point where it seems convenient to use hildon_appview_add_with_scrollbar function from hildon-lgp.<br>Original code after minimal and preliminary hildonization looks like this:
<br><br>[code]<br><br> main = HILDON_APPVIEW (hildon_appview_new ("Main view"));<br> hildon_appview_set_fullscreen_key_allowed(main, TRUE );<br> gtk_widget_show (GTK_WIDGET (main));<br> <br> main_icon_pixbuf = create_pixbuf ("
grsync.png");<br> if (main_icon_pixbuf)<br> {<br> gtk_window_set_icon (GTK_WINDOW (main), main_icon_pixbuf);<br> gdk_pixbuf_unref (main_icon_pixbuf);<br> }<br><br> scrolledwindow1 = gtk_scrolled_window_new (NULL, NULL);
<br> gtk_container_add (GTK_CONTAINER (main), scrolledwindow1);<br> gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW (scrolledwindow1), GTK_POLICY_AUTOMATIC, GTK_POLICY_AUTOMATIC);<br> gtk_widget_show (scrolledwindow1);
<br> <br> viewport1 = gtk_viewport_new (NULL, NULL);<br> gtk_widget_show (viewport1);<br> gtk_container_add (GTK_CONTAINER (scrolledwindow1), viewport1);<br><br>[end code]<br><br>Of course to viewport1 are added all the widget used by the application and the HildonAppView is added to a HildonApp object.
<br>It works unmodified, but then I tried to avoid using the scrolled window: Maemo API documentation for HildonAppView (<a href="http://www.maemo.org/platform/docs/api/hildon-docs/lgpl-html/HildonAppView.html">http://www.maemo.org/platform/docs/api/hildon-docs/lgpl-html/HildonAppView.html
</a>) states that<br><h3>hildon_appview_add_with_scrollbar ()</h3><pre class="programlisting">void hildon_appview_add_with_scrollbar<br> (HildonAppView *self,<br> GtkWidget *child);
</pre><p>
Adds the <i class="parameter"><tt>child</tt></i> to the <i class="parameter"><tt>self</tt></i>(HildonAppView) and creates a scrollbar
to it. Similar as adding first a <i class="parameter"><tt>GtkScrolledWindow</tt></i> and then the
<i class="parameter"><tt>child</tt></i> to it.</p>Resulting code is:<br><br>[code]<br><br> main = HILDON_APPVIEW (hildon_appview_new ("Main view"));<br> hildon_appview_set_fullscreen_key_allowed(main, TRUE );
<br> gtk_widget_show (GTK_WIDGET (main));<br> main_icon_pixbuf = create_pixbuf ("grsync.png");<br> if (main_icon_pixbuf)<br> {<br> gtk_window_set_icon (GTK_WINDOW (main), main_icon_pixbuf);<br> gdk_pixbuf_unref (main_icon_pixbuf);
<br> }<br><br> viewport1 = gtk_viewport_new (NULL, NULL);<br> gtk_widget_show (viewport1);<br> hildon_appview_add_with_scrollbar(main, viewport1);<br> <br>[/end code]<br><br>It produces no compiler error, but by running it (inside scratchbox and on the real device) produces only a blank window with no widget drawn.
<br>What am I doing wrong?<br><br>Luca Donaggio<br>
