i compiled gtk+2.18.6 for use with directfb on an arm target.
When i run the following code i get a segmentation fault in function ( gtk_widget_show_all(window); )
find_native_sibling_above_helper(GdkWindowObject *parent,
GdkWindowObject *child)
in file gdk/gdkwindow.c line 1123.
The parent argument is 0x0.
This is the testapplication:
#include <cairo.h>
#include <gtk/gtk.h>
#include <time.h>
static char buffer[256];
static gboolean
on_expose_event(GtkWidget *widget,
GdkEventExpose *event,
gpointer data)
{
cairo_t *cr;
cr = gdk_cairo_create(widget->window);
cairo_move_to(cr, 30, 30);
cairo_show_text(cr, buffer);
cairo_destroy(cr);
return FALSE;
}
static gboolean
time_handler(GtkWidget *widget)
{
if (widget->window == NULL) return FALSE;
time_t curtime;
struct tm *loctime;
curtime = time(NULL);
loctime = localtime(&curtime);
strftime(buffer, 256, "%T", loctime);
gtk_widget_queue_draw(widget);
return TRUE;
}
int
main (int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *darea;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
darea = gtk_drawing_area_new();
gtk_container_add(GTK_CONTAINER (window), darea);
g_signal_connect(darea, "expose-event",
G_CALLBACK(on_expose_event), NULL);
g_signal_connect(window, "destroy",
G_CALLBACK(gtk_main_quit), NULL);
gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
gtk_window_set_default_size(GTK_WINDOW(window), 320, 240);
gtk_window_set_title(GTK_WINDOW(window), "timer");
g_timeout_add(1000, (GSourceFunc) time_handler, (gpointer) window);
gtk_widget_show_all(window);
time_handler(window);
gtk_main();
return 0;
}
It`s a tutorial linked on gtk.org
This are the versions of the stuff working together with gtk+:
DirectFB-1.4.0.tar.gz
atk-1.25.2.tar.gz
cairo-1.8.6.tar.gz
fontconfig-2.7.0.tar.gz
glib-2.22.4.tar.gz
gtk+-2.18.6.tar.gz
pango-1.26.2.tar.gz
pixman-0.15.16.tar.gz
tslib.tar.gz
liberation-fonts.tar.gz
Can anybody please tell whats going wrong?
Is ther a Bug in gtk_widget_show_all ?
Or are the version i used together are not compatible?
Any Ideas are very welcome,
thank you very much.
Regards,
Bastian.
