Hi,
-
on Qt/Embedded without calling QApp::exec(), if i use processEvents() in a while loop which has some widget creation and deletion also it gives segmentationfault. is it bcoz QEventLoop object is not yet created(may be in exec() call it could be created).
-
if I create my own eventloop object as a public member of MyApplication which inherits QApllication, still same problem is persisting.
Is it bcoz QThreadData object is not created?? -
In the same context, i want to know whether all QTreads are managed with in Qt's own scheduling time at the OS level??
please help me about these issues

Why do you want/need to run your own event loop? You may want to take a look at [[Doc:QAbstractEventDispatcher]] if you wish to customise event handling.

why bcoz i dont want to receive any user invoked events from QWS instaed i receive from another process. I want to block wait on that particular message queue instaed of aboutToBlock() emission by QAbstarctEventDispatcher. As per the information received on message queue i want to create/delete/chage state of objects.-----simply i want to use Qt/Embedded(which has good documentation and user base compared to other Display servers) like Display server only rather than GUI server.
