Problem using QValueList

[yellowmat]

Hi,

I'm developping a class that looks like a list box and manage the displaying and scrolling of items (sound, image and color).

I'm trying to use the QValueList Template but I have a compilation error and I don't know how to fix it. My code is inspired from Qt help but it does not works.

Here is my .h

#ifndef _ITEM_SELECTOR_H
#define _ITEM_SELECTOR_H
 
#include <qwidget.h>
#include <qvaluelist.h>
 
class QListBox;
class CItem;
 
class CItemSelector : public QWidget
{
	Q_OBJECT
 
public:
	// Constructor / Destructor
	CItemSelector(QWidget* parent=0, const char* name=0);
 
 
	// Slots
private slots:
	void processItemSelectionChange(int);
 
public slots:
	void updateHmi(QValueList<CItem>);
 
 
	// Signals
signals:
	void itemSelectionChanged(const CItem&);
 
	// Members
private:
	QListBox* lb;
 
	QValueList<CItem> currentList;
};
 
#endif

#ifndef _ITEM_SELECTOR_H
#define _ITEM_SELECTOR_H

#include <qwidget.h>
#include <qvaluelist.h>

class QListBox;
class CItem;

class CItemSelector : public QWidget
{
	Q_OBJECT

public:
	// Constructor / Destructor
	CItemSelector(QWidget* parent=0, const char* name=0);


	// Slots
private slots:
	void processItemSelectionChange(int);

public slots:
	void updateHmi(QValueList<CItem>);


	// Signals
signals:
	void itemSelectionChanged(const CItem&);

	// Members
private:
	QListBox* lb;

	QValueList<CItem> currentList;
};

#endif

and the .cpp

#include "itemselector.h"
#include <qlistbox.h>
#include ".\\..\\..\\item\\widgetsource\\item.h"
 
CItemSelector::CItemSelector(QWidget* parent, const char* name)
:QWidget(parent, name)
{
	resize(300, 400);
 
	// Create the list box
	lb = new QListBox(this, "lb");
}
 
 
void CItemSelector::updateHmi(QValueList<CItem> list)
{
	// Backup the list
	currentList = list;
 
	// Reset the content of the current list box
	lb->clear();
 
	// Fill the list box with the list items
	QValueList<CItem>::iterator it;
	for(it = list.begin(); it != list.end(); it++)
		lb->insertItem(it.getItemName());
 
}
 
 
void CItemSelector::processItemSelectionChange(int value)
{
	// Process something specific ... eventually
	// TO DO
 
	// Emit the signal
	emit itemSelectionChanged(currentList[value]);
}

#include "itemselector.h"
#include <qlistbox.h>
#include ".\\..\\..\\item\\widgetsource\\item.h"

CItemSelector::CItemSelector(QWidget* parent, const char* name)
:QWidget(parent, name)
{
	resize(300, 400);

	// Create the list box
	lb = new QListBox(this, "lb");
}


void CItemSelector::updateHmi(QValueList<CItem> list)
{
	// Backup the list
	currentList = list;

	// Reset the content of the current list box
	lb->clear();

	// Fill the list box with the list items
	QValueList<CItem>::iterator it;
	for(it = list.begin(); it != list.end(); it++)
		lb->insertItem(it.getItemName());

}


void CItemSelector::processItemSelectionChange(int value)
{
	// Process something specific ... eventually
	// TO DO

	// Emit the signal
	emit itemSelectionChanged(currentList[value]);
}

My compilation error message is the following

ItemSelector.cpp
..\WidgetSource\ItemSelector.cpp(26) : error C2039: 'getItemName' : is not a member of 'QValueListIterator<class CItem>

What does it mean ? How do I can fix my code ?

Thanks in advance.

[yellowmat]

got it.

I forget this line into the .h

#include ".\\..\\..\\item\\WidgetSource\\item.h"

#include ".\\..\\..\\item\\WidgetSource\\item.h"

To copy to clipboard, switch view to plain text mode 

Now it works.

Just a suggestion if I may:
INCLUDEPATH += ..\..\item\widgetsource in your pro file
#include <item.h> in your sources
instead of: #include ".\\..\\..\\item\\WidgetSource\\item.h"
