should i use listview ?

[rimie23]

ok
that's the code of add_object

void OgreWidget::add_object(const Ogre::Vector3 &pos)
{
 
	Ogre::String name1 = "entity " + Ogre::StringConverter::toString(Ogre::Root::getSingletonPtr()->getTimer()->getMicroseconds());
	mEntity = ogreSceneManager->createEntity(name1, Ogre::SceneManager:: PT_CUBE);
 
        Ogre::MaterialPtr material1111 = Ogre::MaterialManager::getSingleton().create("green", "General");
 
 
    material1111->getTechnique( 0 )->getPass( 0 )->setAmbient(1, 1, 0);
    mEntity->setMaterial(material1111);
		Ogre::String name = "Node " + Ogre::StringConverter::toString(Ogre::Root::getSingletonPtr()->getTimer()->getMicroseconds()); // Provides a unique timestamp - the time since the application was started in microseconds.
mNode = ogreSceneManager->getRootSceneNode()->
            createChildSceneNode(name, pos); 
 mNode->attachObject(mEntity);
 count++;
 
 QStandardItem *item=new QStandardItem(QString ("Cube  %0").arg(count));
 
 //model->setItem(count,item);
 model->appendRow(item);
 QListView *listview;
 listview->update();
 
	ogreRenderWindow->update();
   this->update();
 
	}

void OgreWidget::add_object(const Ogre::Vector3 &pos)
{

	Ogre::String name1 = "entity " + Ogre::StringConverter::toString(Ogre::Root::getSingletonPtr()->getTimer()->getMicroseconds());
	mEntity = ogreSceneManager->createEntity(name1, Ogre::SceneManager:: PT_CUBE);
	
        Ogre::MaterialPtr material1111 = Ogre::MaterialManager::getSingleton().create("green", "General");


    material1111->getTechnique( 0 )->getPass( 0 )->setAmbient(1, 1, 0);
    mEntity->setMaterial(material1111);
		Ogre::String name = "Node " + Ogre::StringConverter::toString(Ogre::Root::getSingletonPtr()->getTimer()->getMicroseconds()); // Provides a unique timestamp - the time since the application was started in microseconds.
mNode = ogreSceneManager->getRootSceneNode()->
            createChildSceneNode(name, pos); 
 mNode->attachObject(mEntity);
 count++;
 
 QStandardItem *item=new QStandardItem(QString ("Cube  %0").arg(count));

 //model->setItem(count,item);
 model->appendRow(item);
 QListView *listview;
 listview->update();
	
	ogreRenderWindow->update();
   this->update();

	}

i just do that

[Le_B]

so "model" must be a member variable of OgreWidget
and it must be set somewhere right ?

[rimie23]

beh
i define model in mainwinows

lass MainWindow : public QMainWindow
{
Q_OBJECT
 
public:
 
listView = new QListView(dockWidgetContents_8);
listView->setObjectName(QString::fromUtf8("listView"));
listView->setGeometry(QRect(0, 0, 281, 290));
 
QStandardItemModel *model=new QStandardItemModel();
listView->setModel(model);

lass MainWindow : public QMainWindow
{
Q_OBJECT
 
public:

listView = new QListView(dockWidgetContents_8);
listView->setObjectName(QString::fromUtf8("listView"));
listView->setGeometry(QRect(0, 0, 281, 290));
 
QStandardItemModel *model=new QStandardItemModel();
listView->setModel(model);

i think i bad understand how i use the "model" no? (i modifate qt assistant exemple )

[Le_B]

so you must have a crash when doing model->appendRow(item); in OgreWidget right ?
if it s true it s just that you need that ogreWidget ask for the model pointer to Mainwindow, else how do you want OgreWidget to know what model is ?

[rimie23]

you need that ogreWidget ask for the model pointer to Mainwindow, else how do you want OgreWidget to know what model is ?

how i do that (when i see the exemple in qt assistant it make just like that maybe because he is in the same class?)
so how i said to ogre widget to applicate the model in mainwindows , but at first is my definition of the model in mainwinows true ?

[Le_B]

just create a set_model function(const QStandardItemModel *model) function in ogrewiget that will save the pointer value to a member variable
then call it after you create the model in mainwindow (i suppose you create the ogrewidget in the same function as the model)

[rimie23]

i suppose you create the ogrewidget in the same function as the model)

create model like that ?

model->appendRow(item);

model->appendRow(item);

Ok , i define my model like that
in ogrewidget.cpp

QStandardItemModel* OgreWidget::add_object(/*Ogre::Real*/double offsetX ,/*Ogre::Real*/double offsetY)
{
.................................................
model= new QStandardItemModel();
	int i=1;
    for(itr = result.begin() ;itr != result.end();++itr)
      {
            if(itr->movable)
            {
 
				MarkerNode->_setDerivedPosition(mouseRay.getPoint(itr->distance));
				MarkerNode->setScale(0.1f, 0.1f, 0.1f);
				QStandardItem *item=new QStandardItem(QString ("Marker  %0").arg(i));
				model->appendRow(item);
				i++;
 
            }
      }   
	  return model;
}

QStandardItemModel* OgreWidget::add_object(/*Ogre::Real*/double offsetX ,/*Ogre::Real*/double offsetY)
{
.................................................
model= new QStandardItemModel();
	int i=1;
    for(itr = result.begin() ;itr != result.end();++itr)
      {
            if(itr->movable)
            {
				
				MarkerNode->_setDerivedPosition(mouseRay.getPoint(itr->distance));
				MarkerNode->setScale(0.1f, 0.1f, 0.1f);
				QStandardItem *item=new QStandardItem(QString ("Marker  %0").arg(i));
				model->appendRow(item);
				i++;
				
            }
      }   
	  return model;
}

To copy to clipboard, switch view to plain text mode 

and in my_interface.cpp

list_O = new QToolButton(page_13);            
            list_O->setGeometry(QRect(30, 210, 101, 31));
            list_O->setText(QApplication::translate("MainWindow", "Object Liste", 0, QApplication::UnicodeUTF8));
	  listView =new QListView(list_O);

list_O = new QToolButton(page_13);            
            list_O->setGeometry(QRect(30, 210, 101, 31));
            list_O->setText(QApplication::translate("MainWindow", "Object Liste", 0, QApplication::UnicodeUTF8));
	  listView =new QListView(list_O);

but it still do not make to me the list

i want just to know what i forget to do
