I am writing a library for my movies collection which reads in xml data and stores into a tablewidget for gui/cmdline part. I have a strange error, although i specify that i want to use integer only, the compiler interprets as int& and give me error as below.


qcldata.cpp: In member function ‘bool qcldata::processdata()’:

make: *** [.moc_obj/qcldata.o] Error 1

could someone please help me out with error, i think it is something simple and i am missing it..

Thanks

The 3rd parameter to QTableWidget::setItem() needs to be a pointer to a QTableWidgetItem. You need to create the QTableWidgetItem on the heap using new, instead of on the stack.

eg:

if(k.tagName() == "name"){tabmovies->setItem(counter,0,new QTableWidgetItem(k.text()));}

Hi,

better use
if(k.tagName() == "name"){tabmovies->setItem(counter,0,new QTableWidgetItem(k.text()));}
else if(k.tagName() == "weburl"){ tabmovies->setItem(counter,1,new QTableWidgetItem(k.text())); }
else if(k.tagName() == "year"){tabmovies->setItem(counter,2,new QTableWidgetItem(k.text()));}

it will make your application faster. Further insertRow is the "wrong" function for you because you always add a empty row at 1 but set the content for the last line. So you probably want use QTableWidget::setRowCount().

Thanks.. i have a huge xml file, so takes abt 2 mins to read.. but this was quicker
