Tooltips in QTableWidgetItem

[Arthur]

Hello,

I would like my QTableWidgetItems (and headers) to have tooltips. Using the setToolTip method does not result in the fact that the tooltip is displayed when 'hovering'.

Apparently I missed something, but for instance buttons, etc it works. Could someone help me on this one?

Thanks,

Arthur

Subclass QTableWidgetItem and reimplement data to return whatever text you want for Qt::ToolTipRole (3), like so:

class MyTableWidgetItem : public QTableWidgetItem{
public:
  void setToolTip(const QString &t){ m_tooltip = t; }
  QVariant data(int role){
    return role==3 ? m_tooltip : QTableWidgetItem::data(role);
  }
private:
  QString m_tooltip;
};

class MyTableWidgetItem : public QTableWidgetItem{
public:
  void setToolTip(const QString &t){ m_tooltip = t; }
  QVariant data(int role){
    return role==3 ? m_tooltip : QTableWidgetItem::data(role);
  }
private:
  QString m_tooltip;
};

To copy to clipboard, switch view to plain text mode 

Edit:
I just noticed there is a setData() member available for QTableWidgetItem, so all you have to do is to call setData(3, "My Tooltip");

Thank you, that did the trick
