[rimie23]

Hi,
i want to use many viewport in the same widget (widget subdivised in many viewport ) like this

i have no problem with the subdivision ,i can create two viewport within the lines, within the name of the camera just like this picture(you can see an object 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)


is the best idea to draw lines (edge of viewport) and the name of viewport is the uses og gridlayout?
if yes how i use it in my case ?

id hre another idea ?
