Add support to qlayout for fixed page

Is your feature request related to a problem? Please describe. I have read dozens of posts concerning quasar layout and scrolling. I have responded to quite a few based on my understanding and experimentation. I have spent countless hours reading quasar code and debugging layout in the browser. I think I understand how it works and adding just a little more info to the docs would help. For example: when a drawer is fixed, if the content is to tall for the window it automatically gets a scrollbar. If it is not fixed then the browser window gets a scrollbar.

When the drawers aren’t fixed the browser scrollbar scrolls the drawers and the page. If the drawers are fixed then the browser scrollbar scrolls the page, even though it might be on the other side of the drawer. It will also extend up beside the header if there is one.

All that was background to say that adding the ability to “fix” the page/pagecontainer would cause the page to have its own scrollbar which is preferable in many instances.

Describe the solution you’d like My proposal is that using a capital P in the page position of the layout string “hHh lPr lFf” would fix the page and also provide the magic and automatic scrolling of the page content if necessary. This would work just like using a capital L in the layout string to fix the left drawer prevents it from scrolling with the browser window and instead magically provides a scrollbar if necessary.

Describe alternatives you’ve considered I have implemented a fixed page with a page scrollbar when necessary by

1. adding class="fixed fit scroll" to qpagecontainer in mainlayout.
2. I also had to add class="fit scroll" to the qpage, but I am not sure why.

Adding fixed to the page container gets rid of the browser scrollbar when drawers are fixed, which was my initial goal. My “workaround” requires me to modify every page for it to work. I don’t like that but I am new to quasar and don’t fully understand all the details of the qlayout implementation. I am also not very experienced with CSS.

I modified the example here: https://codepen.io/pdanpdan/pen/bGrRXRR?editors=1000 For the scroll area bar visible or not just play with its properties

You can do it like this: https://codepen.io/pdanpdan/pen/bGrRXRR?editors=1010

But you would lose reveal and QPageScroller
