ASP.net is not a client technology. For client technology, I suggest QMLWeb 
(already linked to & suggested by other replies)
If you are looking for server-side there is nothing, though I wonder about it:

TcpServer {
   PlainTextSocket {
   port: 80
  requestHandler: httpHandler // as opposed to FTP, etc.
   }
   SslSocket {
  port: 443
  requestHandler:  httpHandler // as opposed to FTP, etc.
   }
   HttpRequestHandler {
 id: httpHandler
 cookies: true
 onRequested(path, request, response) { // non standard syntax for 
illustration only
router.route(url, request, response)
 }
   }
  Handler {
   id: router
   sessions: true
   UserHandler {// generic
  path: "user"
  operations: Http.All
  Handler {
operations: [Http.Get]
onRequested(url, request, response) { } // do something app specific
  }
  Handler {
operations: [Http.Post, Http.Put]
  }
   }
   AccountHandler { // app specific, so all the code doesn't go in one file 
 
   }
   LogoutHandler {
   }
   }
}

[Interest] Qt3D RenderCapture

[Harald Vistnes]

Hi,

I'm working on a CAD like application and we want to replace the old
graphics library with Qt3D. An important feature is for the user to be able
to create images of the 3D scene. When generating images, the user must be
able to select background, select which overlay items should be included,
resolution, etc. So the generated image will not be a direct dump of what
is on screen.

In Qt3D there is QRenderCapture, however it only captures the contents of
the framebuffer and returns it as a QImage.

Is it possible to temporarily modify the scene during the capture and then
restore it afterwards (in the slot connected to
QRenderCaptureReply::completeChanged)?

Is it possible to switch surface in the framegraph so that the scene is
rendered into an offscreen surface with the requested resolution during the
capture? Or is there any other way I can force it to render with a
different resolution than the window size?

Thanks,
Harald

Re: [Interest] QMenu size

[Bo Thorsen]

Hi Joshua,

Thanks! These are great ideas. It's not about making it work like
another system, but it is a unique requirement having to do with
recording the screen...


Typical, you actually managed to find a good reason for doing this :)


If you don't mind, could you clarify a bit what you mean with a couple
of your suggestions?


- Work with the width for height tricks


What does this mean?


You could use the heightForWidth() to have some control over the size of 
it. Wouldn't be my first choice here and I'm not even sure where I would 
take it. But I mentioned it because you said you had to control the size 
of it, and this is one of the lesser known tricks that I sometimes use 
to do it.



- You can move the menu after it appears with either a
reimplementation in the resizeEvent, eventFilter on resize or other
events, or using 0 time single shot timer


I understand the first two of these, but where would I implement a 0
time single shot?


The timer is in the class that opens the popup menu. If you have a 
method where you set up the menu, you can do something like this:


QMenu popup;
// set up the menu here
QTimer::singleShot(0, [=]() {
  // Handle popup size here
}
popup.exec();

Bo.

 Hello all,

 I am wondering if there is a way to customize the size of a QMenu used
 as a context menu. I have it so that when I right click, a popup menu
 comes up. But I would like it so the QMenu doesn't ever go outside of
 the window it is clicked in. Right now, if you click near the bottom,
 the QMenu drops below my app. Or if I have a QMenu with a lot of items,
 it breaks it up into two columns worth of items, is there a way to make
 that more (for a wider and less tall sub-QMenu)? Thanks for any
thoughts.


This sounds to me like you are trying to force Qt to do something that
some other system used to do?

I have a lot of requests from customers and I always try to make them
accept that the default way of doing things are there for a number of
reasons and they should accept it the it is. So, my advice is to stop
thinking about this. Or make the guy deciding this stop thinking about
it :)

However, if you can't do that, you always have options. Here are a set
of some of the things I would try:

- Set the maximum height on the QMenu

- Work with the width for height tricks

- You can move the menu after it appears with either a
reimplementation in the resizeEvent, eventFilter on resize or other
events, or using 0 time single shot timer

- There are probably a bunch of possible hacks that might work in the
area of proxy QStyle subclasses

I hope this helps.
