currentIndex().internalPointer() problem

[xgoan]

Hi,

I have this code as part of my Dialog with a QListView and QGraphicsView:

void TextureDialog::on_toolButtonAddLayer_clicked(){
	QString fileName = QFileDialog::getOpenFileName(this, tr("Abrir imagen"), workingDirectory,
		tr("Imagenes (*.png *.xpm *.jpg)"));	
	if(fileName.isEmpty()) return;
	workingDirectory=QFileInfo(fileName).absolutePath();
 
	GraphicsObjectItem *objectItem=objectPreviewScene->addLayer(fileName);
	StandardItem *item=new StandardItem(objectItem, QIcon(fileName), fileName);
	qDebug()<<"objectItem: "<<objectItem<<endl<<item->sceneItem();
	int row=listModelLayers->rowCount();
 
	listModelLayers->appendRow(item);
	listViewLayers->setCurrentIndex(listModelLayers->index(row, 0));
}

void TextureDialog::on_toolButtonAddLayer_clicked(){
	QString fileName = QFileDialog::getOpenFileName(this, tr("Abrir imagen"), workingDirectory,
		tr("Imagenes (*.png *.xpm *.jpg)"));	
	if(fileName.isEmpty()) return;
	workingDirectory=QFileInfo(fileName).absolutePath();
	
	GraphicsObjectItem *objectItem=objectPreviewScene->addLayer(fileName);
	StandardItem *item=new StandardItem(objectItem, QIcon(fileName), fileName);
	qDebug()<<"objectItem: "<<objectItem<<endl<<item->sceneItem();
	int row=listModelLayers->rowCount();
	
	listModelLayers->appendRow(item);
	listViewLayers->setCurrentIndex(listModelLayers->index(row, 0));
}

To copy to clipboard, switch view to plain text mode 

void TextureDialog::moveUp(){
	StandardItem *item;
 
	item=static_cast<StandardItem*>(listViewLayers->currentIndex().internalPointer());
 
	qDebug()<<item->sceneItem();
	//if(item){
		//qDebug()<<item;
	//}
	//qDebug()<<static_cast<QObject*>(item)->objectName();
}

void TextureDialog::moveUp(){
	StandardItem *item;
	
	item=static_cast<StandardItem*>(listViewLayers->currentIndex().internalPointer());
	
	qDebug()<<item->sceneItem();
	//if(item){
		//qDebug()<<item;
	//}
	//qDebug()<<static_cast<QObject*>(item)->objectName();
}

It executes in this order, and the debug exit is:

Ejectuando...
objectItem: QGraphicsItem(this = 0x81cfe78 , parent = 0x0 , pos = QPointF( 0 , 0 ) , z = 0 , flags = { "isVisible|isEnabled" })
QGraphicsItem(this = 0x81cfe78 , parent = 0x0 , pos = QPointF( 0 , 0 ) , z = 0 , flags = { "isVisible|isEnabled" })
QGraphicsItem(0)

Someone can help me to fix this problem?

StandarItem class:

class StandardItem:public QStandardItem{
	public:
		StandardItem(GraphicsObjectItem *item, QIcon icon=QIcon(), QString text=QString());
 
		GraphicsObjectItem* sceneItem();
	private:
		GraphicsObjectItem *m_sceneItem;
};
 
StandardItem::StandardItem(GraphicsObjectItem *item, QIcon icon, QString text):QStandardItem(icon, text){
	m_sceneItem=item;
}
 
GraphicsObjectItem* StandardItem::sceneItem(){
	return m_sceneItem;
}

class StandardItem:public QStandardItem{
	public:
		StandardItem(GraphicsObjectItem *item, QIcon icon=QIcon(), QString text=QString());
		
		GraphicsObjectItem* sceneItem();
	private:
		GraphicsObjectItem *m_sceneItem;
};

StandardItem::StandardItem(GraphicsObjectItem *item, QIcon icon, QString text):QStandardItem(icon, text){
	m_sceneItem=item;
}

GraphicsObjectItem* StandardItem::sceneItem(){
	return m_sceneItem;
}

I have solved it changing the moveUp() function to:

void TextureDialog::moveUp(){
	StandardItem *item=static_cast<StandardItem*>(listModelLayers->itemFromIndex(listViewLayers->currentIndex()));
 
	qDebug()<<item->text()<<endl<<item->sceneItem();
}

void TextureDialog::moveUp(){
	StandardItem *item=static_cast<StandardItem*>(listModelLayers->itemFromIndex(listViewLayers->currentIndex()));
	
	qDebug()<<item->text()<<endl<<item->sceneItem();
}
