I think you're missing a QProcess::start() or equivalent, aren't you?

2008/6/7 Robert Wood &lt;<a \
href="mailto:robert.wood@apostrophe.co.uk">robert.wood@apostrophe.co.uk</a>&gt;: <div \
class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid \
rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I&#39;m trying to \
develop a little open source application to set-up and use Hauppauge boxes on \
Linux. I&#39;m using KDevelop and have got to the stage where I can set-up the \
box and alter its settings just fine. However, what I would now like to do is \
embed a small mplayer Window within my application. 
 
It looks like QXEmbed is what I need to use, but no matter what I have 
tried I cannot get it to work. Someone helped by showing me how to do it 
qt4, but I&#39;d really like to do it with the qt3 libraries as, AFAIK, most 
distributions come with qt3 libraries and not qt4 for the moment. 
 
I have tried the following code (sorry for horrible formatting): 
 
 &nbsp; &nbsp; &nbsp; &nbsp;QXEmbed *eframe = new QXEmbed(this); 
 &nbsp; &nbsp; &nbsp; &nbsp;eframe-&gt;setGeometry(0,0,1280,720); 
 &nbsp; &nbsp; &nbsp; &nbsp;eframe-&gt;show(); 
 &nbsp; &nbsp; &nbsp; &nbsp;QProcess *mp = new QProcess(eframe); 
 
 &nbsp; &nbsp; &nbsp; &nbsp;mp-&gt;setArguments(&quot;/usr/bin/mplayer&quot;); 
 &nbsp; &nbsp; &nbsp; &nbsp;mp-&gt;addArgument(QString(&quot;-wid &quot;) + \
QString::number(eframe-&gt;winId())); &nbsp; &nbsp; &nbsp; \
&nbsp;mp-&gt;addArgument(&quot;/home/robertw/avocent.avi&quot;); 
 &nbsp; &nbsp; &nbsp; &nbsp;if (!mp-&gt;start()) 
 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;{ 
 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; \
&nbsp;textLabel1-&gt;setText(&quot;The application has not started&quot;); \
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;} &nbsp; &nbsp; &nbsp; \
&nbsp;eframe-&gt;setProtocol(QXEmbed::XEMBED); 
 
Now, I think *maybe* I need something like the next line (I realise it&#39;s 
not correct code): 
 
 &nbsp; &nbsp; &nbsp; &nbsp;eframe-&gt;embed(mp-&gt;winId()); 
 
This doesn&#39;t work properly. You can see that eframe is being created 
because it overwrites an existing button, but mplayer is just not 
started. I have tried the same with konsole and the closest I could get 
was to remove the line where it is passed the window ID of eframe and 
then it would just run as a stand alone application. 
 
I am guessing that I am close to achieving what I need to do, but after 
several days of trying am getting nowhere at all. 
 
Would anyone be able to advise? I really would be most grateful!
