Qt3 to Qt4 with QListIterator<AbstractThing *> it() with QPushbutton

[taraj]

Hi,

I am converting a Qt3 App to Qt4 (Qt4.7.1).


I have a class:

class AbstractThing : public QPushButton

class AbstractThing : public QPushButton

To copy to clipboard, switch view to plain text mode 

In Qt3 I had a

class NodeManager : public QObject, QPtrList<AbstractThing>

class NodeManager : public QObject, QPtrList<AbstractThing>

To copy to clipboard, switch view to plain text mode 

I have converted this in Qt4 to

class NodeManager : public QObject, QList<AbstractThing*>

class NodeManager : public QObject, QList<AbstractThing*>

To copy to clipboard, switch view to plain text mode 

I have a function in NodeManager that looks at the items in the QList, in Qt3 I had

void NodeManager::doStuff()
 
AbstractThing *thing;
 
  for(thing = first(); thing; thing = next())
  {
	//stuff
  }

void NodeManager::doStuff()

AbstractThing *thing;
  
  for(thing = first(); thing; thing = next())
  {
	//stuff
  }

To copy to clipboard, switch view to plain text mode 

In Qt4 next() is no longer in Qlist so i have decided to use a QListIterator

QListIterator<AbstractThing *> it();
 
  AbstractThing *thing = first();
 
  while (it.hasNext())
  {
  	thing.setDown(false)
  }

QListIterator<AbstractThing *> it();
  
  AbstractThing *thing = first();
  
  while (it.hasNext())
  {
  	thing.setDown(false)
  }

To copy to clipboard, switch view to plain text mode 

But what do i put in the empty ()? I can't put 'this'


Or will i be better doing a count on the list and a for(int i = 0 .... with item.at(i) etc...


Thank you
Tara
