The QScreenCursor class manages the onscreen mouse cursor in Qt/Embedded. It provides an implementation of a software mouse cursor and can be subclassed by hardware drivers which support a hardware mouse cursor. There may only be one QScreenCursor at a time; it is constructed by <a href="qscreen.html">QScreen</a> or one of its descendants.

<hr><h2><a name="details"></a>Detailed Description</h2>
The QScreenCursor class manages the onscreen mouse cursor in Qt/Embedded. It provides an implementation of a software mouse cursor and can be subclassed by hardware drivers which support a hardware mouse cursor. There may only be one QScreenCursor at a time; it is constructed by <a href="qscreen.html">QScreen</a> or one of its descendants.
<p>
This class is non-portable. It is available <em>only</em> in Qt/Embedded.
It is also internal - this documentation is intended for those subclassing
it in hardware drivers, not for application developers.
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="72008f"></a>QScreenCursor::QScreenCursor()</h3>
<p>Constructs a screen cursor.
<h3 class="fn"><a name="a868e0"></a>QScreenCursor::~QScreenCursor() <code>[virtual]</code></h3>
<p>Destructs a screen cursor, deleting its gfxes, cursor image and
under-cursor storage.
<h3 class="fn">void<a name="2171d0"></a>QScreenCursor::move(intx, inty) <code>[virtual]</code></h3>
<p>Move the mouse cursor to point x,y on the screen. This should be done
in such a way that the hotspot of the cursor is at x,y - e.g. if the
hotspot is at 5,5 within the image then the top left of the image should
be at x-5,y-5.
<h3 class="fn">bool<a name="6e2faf"></a>QScreenCursor::restoreUnder(const<a href="qrect.html">QRect</a>&r, <a href="qgfxrasterbase.html">QGfxRasterBase</a>*g=0) <code>[virtual]</code></h3>
<p>This is relevant to only the software mouse cursor and should be
reimplemented as a null method in hardware cursor drivers. It redraws
what was under the mouse cursor when the cursor is moved.
