c++ - Opening a new form from an existing one - Is this acceptable -

i opening anew form using following method

void myform::myslot() {     //this method loads te form historical feeds     newform *w = new newform();      w->show(); } 

is way acceptable opening new form. how know when delete w pointer when form closes ?

what thinking setting signal trigger when form closed. slot of signal delete w. acceptable way or there faster way accomplish ?

set qt::wa_deleteonclose attribute:

w->setattribute(qt::wa_deleteonclose); 

this way, qt's memory management system deal you.
