<title>Qtopia - The Qt palmtop environment</title>
<body>
<h1><i>Qtopia</i> - The Qt palmtop environment</h1>
<p>
<i>Qtopia</i> is a windowing system for handheld devices. It offers
developers the powerful Qt API, and provides users with fast and
intuitive interaction.
<h2>Developing for <i>Qtopia</i></h2>
<p>
The Qt API includes rich GUI functionality, and is suitable for
both large and small applications.
<p>
Since <i>Qtopia</i> offers the complete Qt API, you can do much of
your development on any of the other platforms for which Qt is
available - Windows, Unix/X11, or Mac OS X. However, for optimal
tailoring of your application to the smaller screen and other
demands of a handheld environment, you should use the <i>Qtopia
SDK</i>.
<p>
The <i>Qtopia SDK</i> allows you to develop <i>Qtopia</i>
applications under the Linux desktop environment using the Qt Virtual
Framebuffer, which completely emulates the handheld <i>Qtopia</i>
environment. It also includes cross-compiler software so that you can
compile your application to run on the target handheld device.
If you do not already have the Qtopia SDK (this document is normally
part of the SDK), contact info@trolltech.com, or see the
<a href=http://www.trolltech.com>Trolltech</a> web site.
<p>To build applications for the SHARP SL5000 or similar StrongARM-based devices,
you will also need a StrongARM cross compiler. Entrants in the programming
contest for this device will have received both the SDK and a cross-compiler.
<p>
The SDK includes an example program. We recommend that you compile and
run this example to learn how things work, before tackling your own
projects.
<p>
To compile the example program for running on the Linux desktop:
<ol>
<li>
<p>
Check the environment is correct:
<p>
<pre>
export OPIEDIR=/opt/Qtopia
export QTDIR=/opt/Qtopia
export PATH=$QTDIR/bin:$PATH
export TMAKEPATH=/opt/Qtopia/tmake/lib/qws/linux-generic-g++
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
</pre>
<li> Take a copy of the example:
<pre>
cd somewhere
cp -r $OPIEDIR/example .
cd example
</pre>
<li> Generate a Makefile:
<pre>
tmake -o Makefile example.pro
</pre>
<li> Build the example:
<pre>
make
</pre>
<li> Install it:
<pre>
su # root privileges required to install
cp example.desktop $OPIEDIR/apps/Applications
cp Example.png $OPIEDIR/pics
cp example $OPIEDIR/bin
exit # no need to be root anymore
</pre>
<li> To run it, first run the Qt Virtual Framebuffer:
<pre>
qvfb &
</pre>
<li> Then run the <i>Qtopia</i> environment:
<pre>
qpe
</pre>
<p>
Your application should be available in the Applications tab visible
inside the Qt Virtual Framebuffer window.
</p>
<li> If you want to distribute your applications to others, build an RPM package, e.g.:
<pre>
mkipks -rpm -arch i386 example.control
</pre>
</ol>
<p>
To make your own application, use the example program as a model. Make sure that
when you add files to your project, you also add them
to your project file (e.g. <tt>example.pro</tt>) and rerun the
<tt>tmake</tt> command to update the <tt>Makefile</tt>.
<p>
To build you application for the SHARP SL5000 rather than just running
on the desktop, the process is similar:
<ol>
<li>
<p>
Check the environment is correctly set for the SHARP SL5000:
<p>
<pre>
export OPIEDIR=/opt/Qtopia/sharp
export QTDIR=/opt/Qtopia/sharp
export PATH=$QTDIR/bin:/usr/local/arm/bin:$PATH
export TMAKEPATH=/opt/Qtopia/tmake/lib/qws/linux-sharp-g++
</pre>
<li> Build and install exactly the same as you did for the desktop
(note that the generated Makefile is different):
<pre>
make clean
tmake -o Makefile example.pro
... <i>etc.</i>
</pre>
<li> To install it on a device, build an ipk package file (you should be root
to do this, since then it will strip the executable for you):
<pre>
mkipks example.control
</pre>
<p>
The resulting <tt>example-1.0.0.ipk</tt> can be installed on the
SL5000 by using <i>Qtopia Desktop</i>.
</p>
</ol>
<h3>Building Your Own Applications</h3>
Once you have built the example, you can proceed with writing
your own applicatons. If you are not familiar with Qt, you should
consult the Qt documentation by pointing your web browser at
<a href=file:/opt/Qtopia/doc/html/index.html><tt>/opt/Qtopia/doc/html/index.html</tt></a>
when you have installed the SDK, or use the online
<a href=http://doc.trolltech.com/>Trolltech Documentation Site</a>.
The <a href="http://www.trolltech.com/products/qt/whitepaper.html">Qt
Whitepaper</a> provides a good overview of, and introduction to, the
Qt API.
<p>
When you add more files to your application, just edit the project
file (e.g. <tt>example.pro</tt>) and rerun the <tt>tmake</tt>
command.
<p>
The <tt>.ui</tt> files are <i>Qt Designer</i> user interface files.
You can create and edit these using <i>Qt Designer</i>:
<pre>
designer example.ui
</pre>
<i>Qt Designer</i>'s online documentation includes a complete
tutorial.
