    Default update the view dynamically

    Hi, i returned with new problem
    as you know i have like that
    in the main i make
    Qt Code: 
    1. #include <QApplication>
    2. #include "my_interface.h"
    3. int main(int argc, char **argv)
    4. {
    5.     QApplication app(argc, argv);
    6.     MainWindow window;
    7.     window.show();
    8. 	window.setViewNum(1);//or window.setViewNum(4);
    9.  
    10.     return app.exec();
    11. }
    To copy to clipboard, switch view to plain text mode 
    in mainwindow.h i make like that
    Qt Code: 
    1. class MainWindow : public QMainWindow
    2. {
    3.     Q_OBJECT
    4. public:
    5.     MainWindow();
    6.    void setViewNum(int num);
    To copy to clipboard, switch view to plain text mode 
    and in the .cpp
    Qt Code: 
    1. MainWindow::MainWindow()
    2. {
    3.  
    4.     mQOgreWidget = new QOgreWidget(this);
    5.  
    6.     setCentralWidget(mQOgreWidget);
    7.  
    8.     if(mQOgreWidget->isVisible())
    9.         mQOgreWidget->setViewNum(1);//or  mQOgreWidget->setViewNum(4);
    10.  
    11. }
    To copy to clipboard, switch view to plain text mode 
    and in QOgreWidget.h
    Qt Code: 
    1. public slots :
    2. void setViewNum(int num);
    3. void setCameraPosition(const Ogre::Vector3 &pos);
    To copy to clipboard, switch view to plain text mode 
    in QOgreWidget.cpp
    Qt Code: 
    1. void QOgreWidget::setViewNum(int num)
    2. {
    3.          if(num == 1)
    4.      {

    To copy to clipboard, switch view to plain text mode 
    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)
    Qt Code: 
    1. QOgreRenderWindow *orw = new QOgreRenderWindow(QString("View0"),mSceneMgr,mRoot,nb_cam,wi,hi);
    To copy to clipboard, switch view to plain text mode 
    and in each time and when i execute "setCameraPosition" i apply
    Qt Code: 
    1. QOgreRenderWindow *orw = new QOgreRenderWindow(QString("View0"),mSceneMgr,mRoot,nb_cam,wi,hi);
    To copy to clipboard, switch view to plain text mode 
    and put it in the layout

    Ok, so make a slot, put that code in the slot. What are you waiting for?
    If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.

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

    figure that out, and put it in a slot.

    Please explain it to me too, otherwise I'll have to delete one of your accounts.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    Qt Code: 
    1. Please explain it to me too, otherwise I'll have to delete one of your accounts.
    To copy to clipboard, switch view to plain text mode 
    OK , delete "dreamvig"
    i can make it but i found that there is problem
    that's the code
    in mainwindow
    Qt Code: 
    1. connect(page_14, SIGNAL(coordinateChanged(const Ogre::Vector3&)),
    2.             mQOgreWidget , SLOT(setCameraPosition(const Ogre::Vector3&)));
    To copy to clipboard, switch view to plain text mode 
    in "setCameraPosition"
    Qt Code: 
    1. void  QOgreWidget::setCameraPosition(const Ogre::Vector3 &pos)
    2. { 
    3. central1 = new QGroupBox("Camera"+nbv, this);
    4. 	 float wi1=central1->width();
    5. 	 float hi1=central1->height();
    6. 	 orw1 = new QOgreRenderWindow(QString("View"+nbv),mSceneMgr,mRoot,nb_cam,wi1,hi1, mNode,pos,nodeM); 
    7. 	  mQOgreRenderWindowList.append(orw1);
    8. 	  nbv++;
    9.  
    10. 	 Layout1 = new QHBoxLayout();
    11.     Layout1->addWidget(orw1);
    12. 	central1->setLayout(Layout1);
    13.  
    14. 	rightSide->addWidget(central1,ligne,colon);
    15. 		colon++;
    16. 	if(colon==3)
    17. 	{
    18. 		colon=0;
    19. 		ligne++;
    20. }♣
    21. }
    To copy to clipboard, switch view to plain text mode 
    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

    This,
    "Camera"+nbv

    probably doesnt do what you think - you are adding a number to a pointer.
    If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.
