# AnyEvent::Impl::Qt(3pm)

AnyEvent adaptor for Qt

## NAME

AnyEvent::Impl::Qt - AnyEvent adaptor for Qt

## SYNOPSIS

```
   use AnyEvent;
   use Qt;

   my $app = Qt::Application \@ARGV; # REQUIRED!

   # this module gets loaded automatically as required
```

## DESCRIPTION

This module provides transparent support for AnyEvent. You don't have to do anything to make Qt work with AnyEvent except by loading Qt before creating the first AnyEvent watcher *and instantiating the* *Qt::Application object*. Failure to do so will result in segfaults, which is why this model doesn't work as a default model and will not be autoprobed (but it will be autodetected when the main program uses Qt).

Qt suffers from the same limitations as Event::Lib and Tk, the workaround is also the same (duplicating file descriptors).

Qt doesn't support idle events, so they are being emulated.

Avoid Qt if you can.

## SEE ALSO

AnyEvent, Qt.
