I created Project in perspective and now I'm facing the problem of resizing when i open my project in perspective workstation. I want that in every screen where i open my project the popup view will cover the whole empty space.
If you design your screens using flex containers or some others they should scale based on the basis, grow and shrink properties.
Using a fixed coorindate container won't resize
That sounds like a very bad idea. This goal sounds like you should just be navigating to a different Page.
