Hi,
I fill the item with "&myspinbutton" and I connect "clicked" signal of a button
to callback function like follows.
void on_checkbutton1_clicked(GtkButton *checkbutton1,gpointer user_data)
{
gchar spin[10];
GtkWidget * window;
if (gtk_toggle_button_get_active(checkbutton1))
{window=gtk_message_dialog_new(NULL,GTK_DIALOG_MODAL |\
GTK_DIALOG_DESTROY_WITH_PARENT,
GTK_MESSAGE_INFO,
GTK_BUTTONS_OK_CANCEL,g_ascii_dtostr(spin,10,gtk_spin_button_get_value((GtkSpinButton*)(user_data))));
g_signal_connect(window,"response",
gtk_widget_destroy,NULL);
gtk_widget_show (window);}
}
And I want to show the value of "myspinbutton" by pass its point to callback
function.But every time I click the button there is no response.Just left
"(gtk_toggle_button_get_active): assertion `GTK_IS_TOGGLE_BUTTON
(toggle_button)' failed".
But if i do not pass the "&spinbutton", and the function only have one
para(GtkButton *checkbutton1), it works,no error,no warning.
I do not know why.Any one could help?Thanks.
Wish you happy.
Dong
