    The only way to be portable amongst Mac / linux / windows is to rely on 3rd party : otherwise, you'll end up writting #ifdef code everywhere (and breakpad is definitely a good idea)

    My real problem is that I am not using gradient but PNG images composed of gradient from opaque to full transparency. Then I have no idea how to render these images without the non-dithering effect then.

    How did you conclude that it did not work? Did you inspect the actual frase_conferma string before sending it? Just trying to help you pinpoint the precise point of failure here... Note that both toLatin1() and toAscii() may be dangerous to use, as you seem to use data in that string that comes from user input directly or indirectly. What happens if one or more of these strings contain characters from another character set?

    Thanks again, ive successfully (after a few more issues that I sorted out) gotten it to stream from my phones camera to the smartcam server. Next step, making the GUI. Once all the bugs are fixed, step after that will be looking at recoding my own smartcam server/webcam filter to support higher resolutions and maybe other things, which I have a feeling will be a lot more trouble than this was.

    the central widgets get always the complete space of the main window which is not covered by dock areas. You might want to add some spacers to "squeeze" the label into the desired place.

    I am not familiar with Xerces, and I don't know what the code above does exactly. But, did you take a look at that QXmlStreamWriter class?

    Hi Andre, thank you for your suggestion. Paint engine is too much for my project. Is there any simple way to do it? What is in my mind now is hide or minimized the print_preview dialog box before grabFrameBuffer and then show or showNormal the dialog box back after grabFrameBuffer. The result that I got is hide() and show() will crash the application. Minimized and showNormal only works on Windows platform. Solaris cant minimized the print_preview dialog box. :(

    Thanks for the info. I added a "wiki article":http://developer.qt.nokia.com/wiki/OS_X_application_without_menu_bar for this, you'll find some info there on how to change your .pro file to grab up your customized Info.plist automatically.

    The program works fine on OS X too. On an older Kubuntu box (8.04) with an old Qt version (4.4.1) there are no warnigs. So, I suggest you go with Tobias' advice and just ignore the glib/dbus warnings.

    I am still would like feed back and am curious to any of those who have had prior experience with the audio api of Qt. Therefore, would it be suited for what I am doing (such as implementing an equalizer while maintaining quality play back) or would I be better to account for each platform I am developing for?

    Hi Vijay, the server operating systems are not officially mentioned on the web page for the supported platforms. But from my experience, I can tell you, it's no probelm :-) Server 2003 is equivalent to Windows XP (kernel side) and has more features for sdervers. Server 2008 R1 is equivalent to Windows Vista Server 2008 R2 is equivalent to Windows 7. So if you look for the corresponding desktop systems, you see where it is supported and up to now it works on the corresponding server systems. Regards Gerolf
