示例1: assert

* View Menu
* Interface modification, load other interfaces, activate Extensions
* \param current, set to NULL for menu creation, else for menu update
**/
QMenu *VLCMenuBar::ViewMenu( intf_thread_t *p_intf, QMenu *current, MainInterface *_mi )
{
QAction *action;

assert( mi );
if( !current )
{
menu = new QMenu( qtr( "&View" ), mi );
}
else
{

//menu->clear();
//HACK menu->clear() does not delete submenus
