adding items in qtablewidget

[jacek]

When I replace j with zero [...] I get cell properly. I found this very odd. Have any ideas about it?

What is the value of "j" just before the insertRow() line?

[Djony]

j is parameter of for loop. Look my first post on this topic

I see it, but there's also "......." in the beginning of the loop body --- maybe you do something with it there?

[Djony]

No, I don't do anything with it. Just use for indexing. Still, have no idea. Very odd...

Does this work on your system?

#include <QApplication>
#include <QTableWidget>
 
const int nRows = 10;
const int nCols = 10;
 
int main( int argc, char **argv )
{
   QApplication app( argc, argv );
 
   QTableWidget tw;
   tw.setColumnCount( nCols );
 
   for( int i = 0; i < nRows; ++i ) {
      tw.insertRow( i );
      for( int j = 0; j < nCols; ++j ) {
         QTableWidgetItem *item = new QTableWidgetItem( QString("(%1,%2)").arg(i).arg(j));
         tw.setItem( i, j, item );
      }
   }
 
   tw.show();
 
   return app.exec();
}

#include <QApplication>
#include <QTableWidget>

const int nRows = 10;
const int nCols = 10;

int main( int argc, char **argv )
{
   QApplication app( argc, argv );

   QTableWidget tw;
   tw.setColumnCount( nCols );

   for( int i = 0; i < nRows; ++i ) {
      tw.insertRow( i );
      for( int j = 0; j < nCols; ++j ) {
         QTableWidgetItem *item = new QTableWidgetItem( QString("(%1,%2)").arg(i).arg(j));
         tw.setItem( i, j, item );
      }
   }

   tw.show();

   return app.exec();
}

Yes, it runs OK. Funny, though, I've noticed some other things about my code for qtablewidget. For some iterations, qtablewidgets prints ok, and for some input not. I understand that strings are most suspicious, but, i've printed them with cout in console, and they are OK, just as they should be. Plus, if I just replace j with zero, code runs well. If I changed just index of rows, then strings aren't problem. Am I wright?

but, i've printed them with cout in console, and they are OK,

What did you try to print exactly? "tr(tempName.toLatin1())" or only "tempName"?

[Djony]

i've printed tempName.toStdString()

[jacek]

Then try printing tr(tempName.toLatin1()).toStdString(). Maybe it gets translated to an empty string?
