|
||
|
|
|
||
|
|
|
||
|
|
Pointer handling in Qt/Embedded works for any mouse or mouse-like
|
||
|
|
device such as touchpanels and trackballs.
|
||
|
|
<p> Usually only one pointer device is supported in an embedded device,
|
||
|
|
but for demonstration purposes, Qt/Embedded includes a large number of
|
||
|
|
supported devices.
|
||
|
|
<p> <h2> Mouse Protocols
|
||
|
|
</h2>
|
||
|
|
<a name="1"></a><p> Mouse drivers can be enabled/disabled via the configure script. Running
|
||
|
|
./configure -help lists the available mouse drivers. Only the
|
||
|
|
"pc" mouse driver is enabled in the default configuration.
|
||
|
|
<p> Provided the "pc" mouse driver is enabled, Qt/Embedded auto-detects the
|
||
|
|
mouse type and device if it is one of
|
||
|
|
the supported types on <tt>/dev/psaux</tt> or one of the <tt>/dev/ttyS?</tt>
|
||
|
|
serial lines. If multiple mice are detected, all may be used simultaneously.
|
||
|
|
<p> Alternatively, you may set the environment variable <tt>QWS_MOUSE_PROTO</tt>
|
||
|
|
to determine which mouse to use. This environment variable may be set
|
||
|
|
to:
|
||
|
|
<blockquote>
|
||
|
|
<em><protocol></em><tt>:</tt><em><device></em>
|
||
|
|
</blockquote>
|
||
|
|
where <em><protocol></em> is one of:
|
||
|
|
<ul>
|
||
|
|
<li> MouseMan
|
||
|
|
<li> IntelliMouse
|
||
|
|
<li> Microsoft
|
||
|
|
</ul>
|
||
|
|
and <em><device></em> is the mouse device, often <tt>/dev/mouse</tt>. If no
|
||
|
|
such variable is specified, the built-in default is <tt>Auto</tt>, which
|
||
|
|
enables auto-detection of the mouse protocol and device.
|
||
|
|
<p> To add another protocol, new subclasses of <a href="qwsmousehandler.html">QWSMouseHandler</a> and
|
||
|
|
<a href="qmousedriverplugin.html">QMouseDriverPlugin</a> can be written and installed as plugins.
|
||
|
|
<p> <h2> Touch Panels
|
||
|
|
</h2>
|
||
|
|
<a name="2"></a><p> Qt/Embedded ships with support for the NEC Vr41XX touchpanel and the
|
||
|
|
emerging linux touchpanel standard used by the iPAQ and Zaurus. These
|
||
|
|
are subclasses of QWSCalibratedMouseHandler which is in turn a subclass
|
||
|
|
of QWSMouseHandler in <tt>embedded/qmouse_qws.cpp</tt>.
