I should write the message and just not send it... :
class CrossTabTreeView : public QTreeView
{
public:
CrossTabTreeView(QWidget* parent = 0) : QTreeView(parent) {}
void resizeEvent(QResizeEvent* /*event - suppress unused warning*/)
{
if (model()->columnCount() == CrossTabView::ColumnCount) {
int scrollBarWidth = 0;
QScrollBar* scrollBar = verticalScrollBar();
if (scrollBar) {
if (scrollBar->isVisible())
scrollBarWidth = scrollBar->width();
}
resizeColumnToContents(CrossTabView::RowColumn);
resizeColumnToContents(CrossTabView::ColumnColumn);
setColumnWidth(CrossTabView::QuestionColumn,
width() - columnWidth(CrossTabView::RowColumn)
- columnWidth(CrossTabView::ColumnColumn) -
scrollBarWidth);
}
}
};
