copied!<p>If you are using <code>QTableView</code>, I presume you use a model linked to this view.</p> <p>One solution would be to use delegates (see <code>QItemDelegate</code>) to paint the progress, In <code>QItemDelegate::paint</code> method you have to define, use <code>QStyle</code> of the widget (<code>widget->style()</code>) to paint the progress (use <code>QStyle::drawControl</code> with <code>QStyle::CE_ProgressBarContents</code> as control identifier).</p> <p>Check the documentation from the example Star Delegate, to see how to define the delegate for the column you need.</p> <p><strong>Later edit:</strong> Example of defining the delegate paint method (code sketch, not really tested, take it as a principle, not fully working).</p> <pre><code>void MyDelegate::paint ( QPainter * painter, const QStyleOptionViewItem & option, const QModelIndex & index ) const { QStyleOptionProgressBar progressStyle; progressStyle.rect = option.rect; // Maybe some other initialization from option would be needed // For the sake of the example, I assume that the index indicates the progress, and the next two siblings indicate the min and max of the progress. QModelIndex minIndex = index.sibling( index.row(), index.column() + 1); QModelIndex maxIndex = index.sibling( index.row(), index.column() + 2); progressStyle.minimum = qvariant_cast< int>( minIndex.data( Qt::UserRole)); progressStyle.maximum = qvariant_cast< int>( maxIndex.data( Qt::UserRole)); progressStyle.progress = qvariant_cast< int>( index.data( Qt::UserRole)); progressStyle.textVisible = false; qApp->style()->drawControl( QStyle::CE_ProgressBarContents, progressStyleOption, painter); } </code></pre>
