gtk_entry from a dialog

Question

I'm trying to create a dialog that pops up when the user selects a specific entry from the combobox, it should record the user input and react accordingly.

here's my code so far:

void add_new_set(GtkWidget entry) { g_print("howdy\n"); } GtkWidget * dialog = gtk_dialog_new_with_buttons("Message",container,GTK_DIALOG_DESTROY_WITH_PARENT,"OK", GTK_RESPONSE_NONE,NULL); GtkWidget * content_area = gtk_dialog_get_content_area (GTK_DIALOG (dialog)); GtkWidget * entry = gtk_entry_new(); gtk_container_add(GTK_CONTAINER(content_area), entry); g_signal_connect_swapped (dialog,"response",G_CALLBACK (add_new_set),dialog); gtk_window_set_modal (GTK_WINDOW(dialog), TRUE); gtk_widget_show_all (dialog);

I need to get the input from the gtk_entry when the OK button is pressed, and perform a string comparison on that function. the g_print line runs when the button is pressed.

thanks

First, that is absolutely the wrong signature for add_new_set(). Not only does it not follow the correct signature for GtkDialog::response, but it also passes a GtkWidget as a parameter. You should never have GtkWidget by itself, always GtkWidget * (a pointer to GtkWidget).

The correct signature for a GtkDialog::response is given in the documentation:

void user_function (GtkDialog *dialog, gint response_id, gpointer user_data)

Second, you will need a way to pass entry in via user_data, either directly or indirectly, and for that g_signal_connect_swapped() is wrong. Use g_signal_connect() instead; the last argument of that becomes the user_data.

Finally, the function to get the text out of a GtkEntry is called, obviously enough, gtk_entry_get_text(). The pointer returned is only valid in the signal handler itself; you will need to copy it if you want to access it later, but for your needs you won't need to.

Good luck.
