A doubt about initialization of variables

[vcp]

Hi,

When I initialize a variable of this way:

QString str=QString()

QString str=QString()

To copy to clipboard, switch view to plain text mode 

or

QStringList lst=QStringList()

QStringList lst=QStringList()

To copy to clipboard, switch view to plain text mode 

what exactly accours? What value is assigned to the variable?

Thanks in advanced

in the first example an empty string in the second an empty list.

Thanks spirit.

You'll also notice this in the documentation.

QString::QString ()
Constructs a null string. Null strings are also empty.

QStringList::QStringList ()
Constructs an empty string list.

and those default constructors are called here as well, without any superficial assignment operation...

QString str;
QStringList sl;

QString str;
QStringList sl;

To copy to clipboard, switch view to plain text mode 

You can call some other constructor than the default constructor like this:

QString str("yep");
QStringList sl(str);

QString str("yep");
QStringList sl(str);

To copy to clipboard, switch view to plain text mode
