QScrollView and repaint

[wysota]

No, they don't.

Shouldn't the lines be drawn as I move the window ? I mean, shouldn't the drawContents be called and the drawing should be updated?

Now, since we know that drawContents is not called, is there a way be which I can detect this and call repaint()

Thanks a lot for your time.

Any ideas on this one ?

Thanks.

A simple way around this is to add a child widget to the scrollview and do all the drawing in the paint event of the widget.

class MyWidget : public QWidget{
public:
  MyWidget(QWidget *parent = 0) : QWidget(parent){}
protected:
  void paintEvent(QPaintEvent *pe){
    //...
  }
};
//...
wid = new MyWidget(viewport());
wid.resize(600, 400);
//...

class MyWidget : public QWidget{
public:
  MyWidget(QWidget *parent = 0) : QWidget(parent){}
protected:
  void paintEvent(QPaintEvent *pe){
    //...
  }
};
//...
wid = new MyWidget(viewport());
wid.resize(600, 400);
//...
