<pre> SDL::Mouse::warp_mouse( $x, $y );

</pre>
<p>Set the position of the mouse cursor (generates a mouse motion event).
Even if the mouse is warped to where it currently is, a mouse motion event is generated.</p>

</div>
<h2 id="set_cursor">set_cursor</h2>
<div id="set_cursor_CONTENT">
<pre> SDL::Mouse::set_cursor( $cursor_object );

</pre>
<p>Sets the currently active cursor to the specified one.
See <a href="SDL-Cursor.html">SDL::Cursor</a> for details on cursor objects.
If the cursor is currently visible, the change will be immediately represented on the display.
<code>set_cursor()</code> can be used to force cursor redraw, if this is desired for any reason.</p>

</div>
<h2 id="get_cursor">get_cursor</h2>
<div id="get_cursor_CONTENT">
<pre> my $cursor_object = SDL::Mouse::get_cursor;

</pre>
<p>Gets the currently active mouse cursor.</p>

</div>
<h2 id="show_cursor">show_cursor</h2>
<div id="show_cursor_CONTENT">
<pre> my $return = SDL::Mouse::show_cursor( $state );

</pre>
<p>Toggle whether or not the cursor is shown on the screen.
Passing <code>SDL_ENABLE</code> displays the cursor and passing <code>SDL_DISABLE</code> hides it.
The current state of the mouse cursor can be queried by passing <code>SDL_QUERY</code>, either <code>SDL_DISABLE</code> or <code>SDL_ENABLE</code> will be returned.</p>
