Solved Draw in an empty QTabWidget

[Mr Gisa]

HI, I was wondering how to draw in an empty QTabWidget.
I noticed that when a QTabWidget has no tabs it's just a white widget with nothing in it, I was wondering how to draw some texts over it and when the user creates a tab it disappears?

Hi
Then you must subclass it and override paintEvent
and handle the no tab logic.

Update:
very fast sample.

class MyTab : public QTabWidget {
  Q_OBJECT
 public:
  explicit MyTab(QWidget* parent = nullptr) : QTabWidget(parent) {}
 protected:
  virtual void paintEvent(QPaintEvent* e ) override {
    QTabWidget::paintEvent(e);
    QPainter painter(this);
    if ( ! count() ) // has no tabs
    {
        painter.drawText( rect(), Qt::AlignCenter, "EMPTY");
    }
  }
};
