possible memory leak help.
Hi,
I have a memory leak problem which I can't seem to understand.
I have a GtkTreeview/ GtkTreeModelFilter/ GtkTreeStore setup.
I have traced it to a case where memory leaks when I call
"gtk_tree_store_set" multiple times.
Here is a snipnet of my code demonstrating the problem. Am I suppose to
free something but I didn't?
... I have selection change call back function setup...
g_signal_connect (G_OBJECT (select), "changed",
G_CALLBACK (FilterviewSelectionChanged_cb), NULL);
void FilterviewSelectionChanged_cb(GtkTreeSelection *sel, gpointer data)
{
GtkTreeIter iter;
GtkTreeModel *model;
gboolean col0;
gchar *col1;
GString *key_col1;
GTree *list;
if (gtk_tree_selection_get_selected (sel,&model,&iter))
{
gtk_tree_model_get (model,&iter,0,&col0, -1);
gtk_tree_model_get (model,&iter,1,&col1, -1);
g_print ("filterview row selected, col0: %d, col1: %s\n", col0,col1);
key_col1 = g_string_new (col1);
list = g_tree_lookup (filterlists, key_col1);
if (list) //found
{
//Not calling GameviewDispalyGTree(list) doesn't seem to show
much
//memory leak... Lets follow it and see what
GameviewDisplayGTree is doing...
GameviewDisplayGTree(list);
}
g_free (col1);
g_string_free (key_col1, TRUE);
}
}
void GameviewDisplayGTree ( GTree *treelist )
{
GtkTreeModel *mod;
gchar str_buf[64];
printf("GameviewDisplayGTree...\n");
mod = gtk_tree_model_filter_get_model(
GTK_TREE_MODEL_FILTER(gameview_treefilt_model));
//Not calling gtk_tree_model_foreach (mod, GameviewDisplayGTreeItem,
treelist)
//doesn't seem to show much memory leak... Checkout
GameviewDisplayGTreeItem.
gtk_tree_model_foreach (mod, GameviewDisplayGTreeItem, treelist);
}
gboolean GameviewDisplayGTreeItem(GtkTreeModel *model,GtkTreePath *path,
GtkTreeIter *iter, gpointer treelist)
{
gchar *char_name;
gint hide_cnt;
GString *name;
GString *value;
/**/
/*# Memory leaks if I call gtk_tree_store_set many times #*/
int i=0;
for (i=0; i<50; i++)
{
printf("GameviewDisplayGTreeItem hide/unhide i: %d\n",i);
gtk_tree_store_set(GTK_TREE_STORE(model),iter,BOOL_VISIBLE,FALSE,-1);
gtk_tree_store_set(GTK_TREE_STORE(model),iter,BOOL_VISIBLE,TRUE,-1);
}
/*#*/
// g_string_free (name, TRUE);
// g_free (char_name);
return FALSE; //continue traversing.
}

On closer inspection, I see that Michael Natterer's patch is already in gtk 2.14.3, and does not solve the problem I mentioned, namely GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed on calling gtk_widget_destroy() on a GtkFileChooserDialog. I guess this patch was incomplete or broken in its application to 2.14.3.

Really noone any ideo how to hide a window to tray when minimized but not when
moving to another desktop with gtk?

GtkFileChooserDialog: something funny?
After updating to glib 2.18.1, gtk 2.14.3 and pango 1.22.0
I'm seeing some funny behavior from GtkFileChooserDialog,
which has started to emit a GLib-GObject-CRITICAL message
on destruction.
Simple test case, based on the example in the documentation
for GtkFileChooserDialog:
void gtk_file_selector_dummy (void)
{
GtkWidget *dialog;
dialog =
gtk_file_chooser_dialog_new("Open File",
NULL,
GTK_FILE_CHOOSER_ACTION_OPEN,
GTK_STOCK_CANCEL,
GTK_RESPONSE_CANCEL,
GTK_STOCK_OPEN,
GTK_RESPONSE_ACCEPT,
NULL);
if (gtk_dialog_run(GTK_DIALOG(dialog)) == GTK_RESPONSE_ACCEPT)
{
gchar *filename;
filename =
gtk_file_chooser_get_filename(GTK_FILE_CHOOSER(dialog));
fprintf(stderr, "got filename '%s'\n", filename);
g_free(filename);
}
fprintf(stderr, "destroying dialog\n");
gtk_widget_destroy(dialog);
fprintf(stderr, "dialog destroyed\n");
}
When I invoke this function I get:
destroying dialog
(gretl:15258): GLib-GObject-CRITICAL **: g_object_unref: assertion
`G_IS_OBJECT (object)' failed
dialog destroyed
Any ideas on what's going on?

gtk+ signal handler problem
Hi, i will really appreciate if anyone can help me! I have just started to use gtk+ and glade with dev-cpp in windows, and i ve been following the tutorial, http://www.micahcarrick.com/12-24-2007/gtk-glade-tutorial-part-1.html#Introduction_to_Glade3.. Finally i have managed to compile and run the sample tutorial code successfully with dev-cpp.. But i suppose there was a problem with the signal handling of gtk.. I ve googled it for hours, and came up with a solution : updating the cross-linker of mingw.. But i could not find out how to update it... I cant get rid of that GTK-warning: could not find signal handler.. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
