One example of gtk-demo called 'expander', everytime when I double-click this
function will make gtk-demo carshed with (!) "[ 1370: 12.312] --> Caught
signal 11 (at 0x54, invalid address) <--Killed".
Its source is as following:
/* Expander
*
* GtkExpander allows to provide additional content that is initially hidden.
* This is also known as "disclosure triangle".
*
*/
#include <gtk/gtk.h>
static GtkWidget *window = NULL;
GtkWidget *
do_expander (GtkWidget *do_widget)
{
GtkWidget *vbox;
GtkWidget *label;
GtkWidget *expander;
if (!window)
{
window = gtk_dialog_new_with_buttons ("GtkExpander",
GTK_WINDOW (do_widget),
0,
GTK_STOCK_CLOSE,
GTK_RESPONSE_NONE,
NULL);
gtk_window_set_resizable (GTK_WINDOW (window), FALSE);
g_signal_connect (window, "response",
G_CALLBACK (gtk_widget_destroy), NULL);
g_signal_connect (window, "destroy",
G_CALLBACK (gtk_widget_destroyed), &window);
vbox = gtk_vbox_new (FALSE, 5);
gtk_box_pack_start (GTK_BOX (GTK_DIALOG (window)->vbox), vbox, TRUE, TRUE,
0);
gtk_container_set_border_width (GTK_CONTAINER (vbox), 5);
label = gtk_label_new ("Expander demo. Click on the triangle for details.");
gtk_box_pack_start (GTK_BOX (vbox), label, FALSE, FALSE, 0);
/* Create the expander */
expander = gtk_expander_new ("Details");
gtk_box_pack_start (GTK_BOX (vbox), expander, FALSE, FALSE, 0);
label = gtk_label_new ("Details can be shown or hidden.");
gtk_container_add (GTK_CONTAINER (expander), label);
}
if (!GTK_WIDGET_VISIBLE (window))
gtk_widget_show_all (window); //crashed here
else
gtk_widget_destroy (window);
return window;
}

主题： Re: Re: Re: [directfb-dev] Warninig in Pango and Fontconfig
Hi,
The warnings are normal, they just tell you that there is not DirectFB
support for that particular GDK functionality. You could implement it ;)
Which functions crash?
Could you send an example and log?
If you send the email to the directfb-dev list too, there is more people
that could help you.

Pedro Aguilar
