I have a very simple example where I add a row to a table, set some text into
the first column, and then setNumRows(0) and the program crashes with *** glibc detected *** double free or corruption (fasttop): 0x085762e8 *** Environment SUSE LINUX 10.0 (i586) perl-Qt -Version: 3.008-132 Installed: 3.008-132 perl 5.8.7-5.3 Am I doing something stupid? I'd be happy to tar up the files and include them here if that would be appropriate. Thanks, Joe Claborn _______________________________________________ Kde-perl mailing list Kde-perl@... https://mail.kde.org/mailman/listinfo/kde-perl |

I tried perl-Qt 3.009b2 with the same results. Do you have a patch for the
malloc check, or some pointers in the right direction?

Gary,
I once used the method without any problem. This is the code snippet I found. It is generated by Designer, thus the cast to int. It shouldn't be actually be necessary. my_table = Qt::Table(my_box, "my_table"); ... my_table->setNumRows( int(0) ); Post your code if this doesn't help. Cheers, Ole Gary L.
