hi I want to use a file selector
http://developer.gnome.org/doc/API/2.0/gtk/GtkFileSelection.html describe one of the possible utilisation
but the code given in example looks strange , correct me if I am wrong but following code can' t work :
void store_filename (GtkFileSelection *file_selector, gpointer user_data){ }
void create_file_selection (void) {
GtkWidget *file_selector;
file_selector = gtk_file_selection_new ("Please select a file for editing.");
g_signal_connect (GTK_OBJECT (GTK_FILE_SELECTION (file_selector)->ok_button),
"clicked",
G_CALLBACK (store_filename),
NULL);
}the item sent to the handler is a GtkButton, and handler wait for a GtkFileSelection so storing the filename with this method is not possible
following the log of the test program with the method from API
GLib-GObject-WARNING **: invalid cast from `GtkButton' to `GtkFileSelection' (projet:1056): Gtk-CRITICAL **: file gtkfilesel.c: line 1242 (gtk_file_selection_get_filename): assertion `GTK_IS_FILE_SELECTION (filesel)' failed
so i don' t think being wrong. so the handler to use shoud be
void store_filename (GtkButton *ok_button, GtkFileSelection){ }
and the connect :
g..connect(GTK_OBJECT (file_selector->ok_button),"clicked",G_CALLBACK
(store_filename),file_selector);but I don' t like that, because I d like to store filename in another variable that i can pass to create_file_selection() or in another way, not a local variable to store_filename() How could I do?
