update the view dynamically

[rimie23]

Hi, i returned with new problem
as you know i have like that
in the main i make


#include <QApplication>
#include "my_interface.h"
int main(int argc, char **argv)
{
QApplication app(argc, argv);
MainWindow window;
window.show();
window.setViewNum(1);//or window.setViewNum(4);

return app.exec();
}


in mainwindow.h i make like that


class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow();
void setViewNum(int num);

and in the .cpp


MainWindow::MainWindow()
{

mQOgreWidget = new QOgreWidget(this);

setCentralWidget(mQOgreWidget);

if(mQOgreWidget->isVisible())
mQOgreWidget->setViewNum(1);//or mQOgreWidget->setViewNum(4);

}

and in QOgreWidget.h

public slots :
void setViewNum(int num);
void setCameraPosition(const Ogre::Vector3 &pos);

in QOgreWidget.cpp


void QOgreWidget::setViewNum(int num)
{
if(num == 1)
{

QWidget *central0 = new QGroupBox("My Scene", this);
float wi0=central0->width();
float hi0=central0->height();

QHBoxLayout* Layout0 = new QHBoxLayout();
Layout0->addWidget(orw0);

central0->setLayout(Layout0);


mVerticalLayout->addWidget(central0);

}

as you know that work
Now i add this function "setCameraPosition" that work too (it add to me an object )
The question or the problem now
1-i want when i execute ""setCameraPosition"" i add than view
is it possible ?
that mean i
i want in the start of the program i see only the left view (i execute only)


QOgreRenderWindow *orw = new QOgreRenderWindow(QString("View0"),mSceneMgr,mRoot,nb_cam,wi,hi);

and in each time and when i execute "setCameraPosition" i apply

QOgreRenderWindow *orw = new QOgreRenderWindow(QString("View0"),mSceneMgr,mRoot,nb_cam,wi,hi);
and put it in the layout

[amleto]

aren't you also dreamvig?

Ok, so make a slot, put that code in the slot. What are you waiting for?

[rimie23]

What i make as slot ? all this function ?


void QOgreWidget::setViewNum(int num)

[amleto]

are you also dreamvig?

[rimie23]

yes , i explained to you why i have two account

[amleto]

What do you want to happen when you push the button?

figure that out, and put it in a slot.

[rimie23]

yes
it work thanks

[wysota]

yes , i explained to you why i have two account

Please explain it to me too, otherwise I'll have to delete one of your accounts.

[rimie23]

Please explain it to me too, otherwise I'll have to delete one of your accounts.
OK , delete "dreamvig"
i can make it but i found that there is problem
that's the code
in mainwindow


connect(page_14, SIGNAL(coordinateChanged(const Ogre::Vector3&)),
mQOgreWidget , SLOT(setCameraPosition(const Ogre::Vector3&)));

in "setCameraPosition"


void QOgreWidget::setCameraPosition(const Ogre::Vector3 &pos)
{
central1 = new QGroupBox("Camera"+nbv, this);
float wi1=central1->width();
float hi1=central1->height();
orw1 = new QOgreRenderWindow(QString("View"+nbv),mSceneMgr,mRoot,nb_cam,wi1,hi1, mNode,pos,nodeM);
mQOgreRenderWindowList.append(orw1);
nbv++;

Layout1 = new QHBoxLayout();
Layout1->addWidget(orw1);
central1->setLayout(Layout1);

rightSide->addWidget(central1,ligne,colon);
colon++;
if(colon==3)
{
colon=0;
ligne++;
}♣
}

but when i run i look that the name of group box is
if i execute 1 time "setCameraPosition" : amera
the seconde one // : mera
3 time: era
4 time: ra
5 :a
and it make exeption when i want add the 6 th

and that waht i see when idebug

EDIT

it work now thanks ror ameleto

orw1 = new QOgreRenderWindow(QString ("View %0").arg(nbv)

[amleto]

This,
"Camera"+nbv

probably doesnt do what you think - you are adding a number to a pointer.

[rimie23]

yes for that i change and i make like that
(QString ("View %0").arg(nbv)
that work
