Hi
i change the idea
because i see this software "vicon" it similar as what i want

now when i run my project my scene is rendred in all the window(central window)

to make it like the photi i have two idea and their problem if you can advice to me what is the appropriate idea
1- the first idea i can devise y window with ogre like the photo BUT when i separate i can't make the lines that mean i cant defrent betewwen the veiw AND i can't write the name of the viewport is there methode in qt to draw lines like that(like the picture)(line in blue and lines in white , the lines that represent the edge of each viewport ?

2-i less the central widget as it , and i add otheres scorelarea to render the scene with the camera in it , BUT her the problem is how i said in my program to render the scen inside the scroller area

1 - yes. Just use paintEvent and draw whatever you want.

2 - I don't understand.
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.

Quoted

Just use paintEvent and draw whatever you want

if i can it don not exist problem for me

But can you more explain to the idea of how i draw ?
for exemple
in my painevent to draw my scene i make like that

Source code

void OgreWidget::paintEvent(QPaintEvent *e)
{
	mRoot->_fireFrameStarted();
	mWindow->update();
		mRoot->_fireFrameEnded();
		e->accept();
}

and with this code

Source code

3
4
5

Ogre::Viewport* vp1 =  mWindow->addViewport( mCamera1); //default values, rendered in the whole window
vp1->setBackgroundColour(Ogre::ColourValue(0,0,0));
 // Alter the camera aspect ratio to match the viewport
mCamera1->setAspectRatio(Ogre::Real(vp1->getActualWidth()) / Ogre::Real(vp1->getActualHeight())); 

Ogre::Viewport* vp2 = mWindow->addViewport( mCamera2, 1 , 0.75, 0.75, 0.25, 0.25 ); //small viewport, rendered in the lower right corner of the window (the 0.75's define the position, the 0.25's define the size
// Set backgrounc color
vp2->setBackgroundColour( Ogre::ColourValue( 1, 0, 0 ) );
mCamera2->setAspectRatio( Ogre::Real(vp2->getActualWidth()) / Ogre::Real(vp2->getActualHeight())); //don't forget to set the aspect ratio of the second camera

i can create two viewport within the lines, within the name of the camera just like this picture(you can see an bject in the big window andn small object in the small window there is no edge between the viewport for that we can't defer betewwen the both viewport)

you know, you could also just put your viewport widget inside a layout and add some margin, then there would be some space between different widgets.

thatnks for this idea
you mean
i create in my mainwidow many layout ?
big one for all the scene and the otheres for the small viwport?

EDIT
d'ont forget the big view and the other viewport all in in one widget

when i make that

Source code

 
1

MainWindow::MainWindow()  
    {  
        this->setBaseSize(1500,1500);  
        my_calsseWidget = new my_classe(this);  
          
        setCentralWidget(my_calsseWidget);

i will see all the viewport (the big and the smallers )
is that mean i must use one layout (because all the viewport are in one widget)

Just look at spacers and layouts. One widget can only have one layout, but e.g. gridlayout can have sub-layouts.

I suggest you do some reading and experimenting.

look, you think about it for yourself for a second.

all those small camera view ports can be made into their own widget and put where the small group boxes are.
