控制GTK选择

假设屏幕上的键盘按钮是Gtk.button,请将这两个按钮组合起来

void on_clicked (GtkButton *button, gpointer data)
{
gtk_entry_buffer_insert_text (buffer,\
                             gtk_entry_buffer_get_length (buffer) + 1,\
                             "blablablah",\ 
                             -1)
gtk_entry_grab_focus (entry)
gtk_editable_set_position (GTK_EDITABLE (entry), -1)
}
