    <p>I have a <code>QTableWidget</code> with which I can add rows by pushing a button. The problem is that I have <code>_table-&gt;setSortingEnabled(true);</code>, and when I'll insert a new row, I won't know where it is. Because since I have set the table sortable, when I add a row, this row will move to it's position (depending on which column is sorted). How can I know which one it is then?</p> <p>Example with one column (Name) sorted by alphabetical order:</p> <pre><code>Name | ------ abc toto zozo </code></pre> <p>If I now add a row like follow :</p> <pre><code>int newRow = _table-&gt;rowCount(); _table-&gt;insertRow(newRow); QTableWidgetItem *item1 = new QTableWidgetItem; item1-&gt;setText("boom"); _table-&gt;setItem(newRow, 0, item1); </code></pre> <p>The row will go between 'abc' and 'toto'.</p> <pre><code>Name | ------ abc &lt;&lt;&lt; boom toto zozo </code></pre> <p>Here it'll work properly, but I have multiple columns and if now I try for example:</p> <pre><code>QTableWidgetItem *item2 = new QTableWidgetItem; item1-&gt;setText("45"); _table-&gt;setItem(newRow, 1, item2); </code></pre> <p>The value that'll change is the value of the second column of 'zozo' and not the one I want, 'boom'.</p> <p>I tried to explain with an example the problem, I hope it helped. So how can I add a new row, set it's text for each of its column if I have the sorting enable on my <code>QTableWidget</code> ?</p> <p><strong>Edit : Answer from nonexplosive (in the comments) :</strong></p> <p>Just need to do like follow for the second <code>QWidgetItem</code> :</p> <pre><code>QTableWidgetItem *item2 = new QTableWidgetItem; item1-&gt;setText("45"); _table-&gt;setItem(item1-&gt;row(), 1, item2); // change newRow by item1-&gt;row() </code></pre>

    2. COit may be easier to use model/view for this, but why not inserting the row just at the end and sort it by the last column where it was sorted?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
