[SOLVED] share data between caller and slot

[whites11]

hi.
my need is to pass data between a method that calls an async request and the slot that is connected to the relative signal.

an example to make this clear:

void foo()
{
   QString str1 = "str1";
 
   connect(requestManager, SIGNAL(requestFinished()), this SLOT(slot2()));
 
   this->requestManager->startRequest(); //emits requestFinished()
}
 
void slot2()
{
  //here i need str1 from foo
}

void foo()
{
   QString str1 = "str1";

   connect(requestManager, SIGNAL(requestFinished()), this SLOT(slot2()));

   this->requestManager->startRequest(); //emits requestFinished()
}

void slot2()
{
  //here i need str1 from foo
}

To copy to clipboard, switch view to plain text mode 

requestManager is an unmodifiable class.
one way is to save str1 as a member of the class, but i'm wondering if there is a better way to do this.


thanks in advance for any answer

your requestManager is a QObject inherited, that's why you can add a property to it and retrieve it within ANY slot (not only in your class)

const char * MY_PROPERTY_NAME = "property name";
void foo()
{
   QString str1 = "str1";
 
   requestManager->setProperty( MY_PROPERTY_NAME, str1 );
 
   connect(requestManager, SIGNAL(requestFinished()), this SLOT(slot2()));
 
   this->requestManager->startRequest(); //emits requestFinished()
}
 
void slot2()
{
  //here i need str1 from foo
  QString str1 = sender()->property( MY_PROPERTY_NAME ).toString();
}

const char * MY_PROPERTY_NAME = "property name";
void foo()
{
   QString str1 = "str1";

   requestManager->setProperty( MY_PROPERTY_NAME, str1 );

   connect(requestManager, SIGNAL(requestFinished()), this SLOT(slot2()));
 
   this->requestManager->startRequest(); //emits requestFinished()
}

void slot2()
{
  //here i need str1 from foo
  QString str1 = sender()->property( MY_PROPERTY_NAME ).toString();
}
