Re: GTK Drag Filename Drop from other Windows

GChecksum assertion failed
Hello. I have this small example where I create a GChecksum and apply some data. The problem is when I request the digest, the program prints out the following error: (process:8422): GLib-CRITICAL **: g_checksum_get_digest: assertion `*digest_len = len' failed My GChecksum code is: char data[] = Hello, World; int len; GChecksum *checksum; guint8 *b_digest; gsize b_digest_len; checksum = g_checksum_new(G_CHECKSUM_MD5); len = strlen(data) + 1; b_digest_len = len; g_checksum_update(checksum, data, len); g_checksum_get_digest(checksum, b_digest, b_digest_len); I initialize the digest len with the length of data. Am I doing something wrong? Please help. Greets, Luka ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Am I doing something wrong? yes, you're not reading the documentation: @digest_len: The caller initializes it to the size of @buffer. After the call it contains the length of the digest. the buffer is a pointer to an array of bytes, since g_checksum_get_digest() doesn't handle the string you pass to g_checksum_update(). as GChecksum handles different hashing algorithms, the array size must be at least big enough to fit the actual size of the digest. the size of the digest for a particular checksum algorithm is obtained using: gsize digest_len = g_checksum_type_get_length (G_CHECKSUM_MD5); which can then be used to allocate an array of bytes: guint8 *digest = g_new (guint8, digest_len); and then you can get the digest: g_checksum_get_digest (checksum, digest, digest_len); you then obviously need to free the digest when you're done using it: g_free (digest); this obviously implies you want the digest as a raw binary vector. if you want the hexadecimal version in string you're much better off using g_compute_checksum_for_string() instead. ciao, Emmanuele. -- Emmanuele Bassi, W: http://www.emmanuelebassi.net B: http://log.emmanuelebassi.net ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
gtk_file_chooser_button_new unexplicabile warnings
Hello. I am developing an application in Mandriva OS and I've got this strange problem in my program : I'm using gtk_file_chooser_button_new function to create a choose folder button from which i can choose a directory where to save some files for example. It works but when I run the application as root it gives me 2 identical warnings : no such file or directory. If I run the app as user then i won't receive this warnings. It could be problem with permissions somewhere? Or what could be the problem because I've tried a lot of methods to solve this problem but nothing good. -- View this message in context: http://www.nabble.com/gtk_file_chooser_button_new-unexplicabile-warnings-tp18826746p18826746.html Sent from the Gtk+ - Apps Dev mailing list archive at Nabble.com. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
How to convert GtkWidget into GdkPixbuf
Hi, I dont really know if I should send this e-mail to that address but I do need help!! that Im trying to print a report that comes from an application built in GtkHTML which has a bug that makes printing not to be like they are showed in the application. I found some code but it doesnt work with scrolled bars. Ive tested nearly everything to make it work with no results, obviously :-), and my last idea is converting all to an image and work from there. Please try to help me if you have some relevant information, Im driving crazy myself trying to solve it. Sorry for my English, I hope you can understand all Im trying to tell you :-).

Both work on immediate children. You must call them recursively,
something like that:
void
action(GtkWidget *widget)
{
/* Do something */
}
void
callback(GtkWidget *widget)
{
action(widget);
if (GTK_IS_CONTAINER(widget))
gtk_container_foreach(GTK_CONTAINER(widget),
callback, NULL);
}
gtk_container_foreach() is the way: the forall() version
traverses also internal stuff I think you don't care about.
Ciao
Almost there. I wrote a function, findWidget() below, to find a widget
by name. This was needed because I'm adding objects to the interface
after Glade has built the interface. It works, but I'm sure it's laeking
memory like a sieve. Whenever I try to free the memory I have problems.
How and where should the memory get freed? Can I get a code review?
/* Recursivly find a widget by name and return it's reference. */
GtkWidget * findWidget(GtkWidget *p, const char *str) {
GList *children=NULL;
GList *child=NULL;
GtkWidget *w=NULL;
children=gtk_container_get_children(GTK_CONTAINER(p));
child=children;
while(child) {
w=GTK_WIDGET(child-data);
if(w!=NULL w-name!=NULL) {
g_debug(Name is {%s}\n, w-name);
}
if(w!=NULL GTK_IS_CONTAINER(w) w-name!=NULL strcmp((char
*)w-name, str)!=0) {
w=findWidget(w, str);
if(w!=NULL w-name!=NULL strcmp((char *)w-name, str)==0) {
break;
} else {
child=g_list_next(child);
}
} else {
break;
}
} /* end of while() */
child=g_list_next(child);
// PROBLEMS freeing memory
//g_list_foreach(children, (GFunc)freeGList, NULL); // ERROR: double
free or corruption
//g_list_foreach(children, (GFunc)g_free, children-data); // ERROR
//g_list_free(children); // ERROR
return w;
}
/* Callback for freeing memory in a GList. */
void freeGList(gpointer *data, gpointer *user_data) {
GList *gl=(GList *)data;
g_free(gl-data);

Re: Can't install gtkmm (package manager won't install libgtkmm-2.4-dev)
This is unusual on a stable Ubuntu release. Anyway, Ubuntu's launchpad is the best place to get help about it, I guess. Thanks Murry, I re-installed Ubuntu 8.04 from the CD, and then installed gtkmm BEFORE allowing the Ubuntu updates to install. I've submitted a bug in the proper Ubuntu place.
