create a new widget dynamically

[Talei]

Camera:
I would keep only one camera, so in each viewport class I would keep current viewport camera position. In repaint function, for each viewport, simply move camera around, no need for multiple cameras.

VBO:
I don't know, maybe Ogre by default uses VBO (I saw on Ogre wiki that there is some sort of asset manager but didn't find any info regarding internal VBO usage, search Ogre wiki/forum) so then there is no problem, as I said before I didn't use Ogre. But this is just for performance and if you scene is simple then there won't be any performance impact (but this is not the "right" way to do this because currently immediate mode is treated as depreciate).

No, i can't i must use many camera
because the aim of my project is to use many camera and render what see each frame


i think i must change all 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
