It works If I use the following block of code instead (It is taken from TestQtSQLDatabase.cxx):<br><br>vtkQtTableModelAdapter* model = new vtkQtTableModelAdapter(table);<br>QTableView* view = new QTableView();<br> view->setModel(model);<br>
view->show();<br><br><br>Please let me know If anybody knows why the first block does not work.<br>Thanks a lot.<br><br>By the way, I have been using VTK nightly for these experiments.<br>Aytekin<br><pre><br></pre><br>

I just wrote some code to display the data in the table and it works. There is data in the table. It looks like the following code segment does not work as I expected. Also, a table shows up but it disappears quickly. <br>
<div class="im">
<br> VTK_CREATE(vtkQtTableView, tableView);<br> tableView->SetSplitMultiComponentColumns(true);<br> tableView->AddRepresentationFromInput(table); //check here<br> tableView->Update(); <br> tableView->GetWidget()->show();<br>

</div>I believe SQL queries are one-time-use objects, so once you traverse<br>
them once, they will be "empty". Try getting rid of your initial<br>
manual traversal, or create a new query for the vtkRowQueryToTable<br>
filter.<br>
<br>
Another useful thing is to "dump" the output table to see what it is<br>
with table->Dump().<br>
