[solved]cmd/*cmd

[tecky]

1. what is the different between:
   @
   QPushButton cmd("ADD");
   QPushButton *cmd = new QPushButton("ADD");
   @

2. why in this line "*" is required :
   @
   QObject::connect(&*cmd, SIGNAL(clicked()),
   @

but in this dont:

@
l->addWidget(cmd);
@

P.S. after previewing post i pressed "ctrl+r" ,habitually (refresh page) hahaha

[stereomatching]

@QPushButton cmd("ADD"); //the resource is allocated on stack
QPushButton *cmd = new QPushButton("ADD"); //the resource is allocated on heap@

you could use directly if cmd is a pointer, using "&*" is weird even it work
@QObject::connect(cmd, SIGNAL(clicked()),@

Please pick a good book of C++--recommend c++ primer 5
if you are running out of time, try "essential c++"

Hmm, basic C++ issue. Another good book is: Introduction to C++ with Qt. Gives perfect education of C++ while using the basics of Qt
