How big is big for a qtable (2 m rows is to big) ?

[tuan]

I am having a problem trying to print a vector of 2 000 000 rows x 4 columns of dates and float and display it into a qTable. Around row 400 000 rows, the application cores. with the following error message :

std::bad_alloc()

Bizarrely enough :

myTable->setNumRows(2000 000);
myTable->setNumCols(4);

myTable->setNumRows(2000 000);
myTable->setNumCols(4);

To copy to clipboard, switch view to plain text mode 

is fine,

but the program cores in the middle of this loop :

for(int line=0; line < 3000000; ++line)
	{
        ....
	    myTable->setText(line,0,"dummy string");
       ....         
}

for(int line=0; line < 3000000; ++line)
	{
        ....
	    myTable->setText(line,0,"dummy string");
       ....         
}

To copy to clipboard, switch view to plain text mode 

I have 2 gig or RAM + 4 gig of swap, so I I do not think that I run out of memory.

Does anybody have an idea ?

Thanks.

Tuan.
