<p>IMPORTANT NOTE: THIS MODULE IS DEPRECATED IN PYGAME 2.2</p>
|
||
|
|
<p>In older pygame versions before pygame 2, <a class="tooltip reference internal" href="event.html#module-pygame.event" title=""><code class="xref py py-mod docutils literal notranslate"><span class="pre">pygame.event</span></code><span class="tooltip-content">pygame module for interacting with events and queues</span></a> was not well
|
||
|
|
suited for posting events from different threads. This module served as a
|
||
|
|
replacement (with less features) for multithreaded use. Now, the usage of this
|
||
|
|
module is highly discouraged in favour of use of the main <a class="tooltip reference internal" href="event.html#module-pygame.event" title=""><code class="xref py py-mod docutils literal notranslate"><span class="pre">pygame.event</span></code><span class="tooltip-content">pygame module for interacting with events and queues</span></a>
|
||
|
|
module. This module will be removed in a future pygame version.</p>

<p>For each frame of your game, you will need to make some sort of call to the
|
||
|
|
event queue. This ensures your program can internally interact with the rest
|
||
|
|
of the operating system.</p>
|
||
|
|
<p>This function is not necessary if your program is consistently processing
|
||
|
|
events on the queue through the other <a class="tooltip reference internal" href="#module-pygame.fastevent" title=""><code class="xref py py-mod docutils literal notranslate"><span class="pre">pygame.fastevent</span></code><span class="tooltip-content">pygame module for interacting with events and queues</span></a> functions.</p>
|
||
|
|
<p>There are important things that must be dealt with internally in the event
|
||
|
|
queue. The main window may need to be repainted or respond to the system. If
|
||
|
|
you fail to make a call to the event queue for too long, the system may
|
||
|
|
decide your program has locked up.</p>

<p>Returns the current event on the queue. If there are no messages

|
<p>This will post your own event objects onto the event queue. You can post
|
||
|
|
any event type you want, but some care must be taken. For example, if you
|
||
|
|
post a MOUSEBUTTONDOWN event to the queue, it is likely any code receiving
|
||
|
|
the event will expect the standard MOUSEBUTTONDOWN attributes to be
|
||
|
|
available, like 'pos' and 'button'.</p>
|
||
|
|
<p>Because pygame.fastevent.post() may have to wait for the queue to empty,
|
||
|
|
you can get into a dead lock if you try to append an event on to a full
|
||
|
|
queue from the thread that processes events. For that reason I do not
|
||
|
|
recommend using this function in the main thread of an SDL program.</p>
