2-dimensional scrolling widget.

An example of CPopupNavigator

CPopupNavigator is designed for scrolling in both direction (horizontal and vertical) at the same time. Main frame represents the scrollable area, and the slider inside the frame corresponds to the visible part.

Slider is draggable within the frame (panning mode on). This behavior is enabled by default. If you want to disable the panning, use enablePanning(false).

To use CPopupNavigator, attach it to the source widget (which content is to be scrolled) using one of connectSource() methods. Currently QAbstractScrollArea and QAbstractSlider descedants can be handled by CPopupNavigator.

// a QGraphicsView is a descedant of the QAbstractScrollArea
QGraphicsView *myView;
 
...
 
// create CPopupNavigator and connect it to the QGraphicsView
CPopupNavigator *myPanner = new CPopupNavigator(this);
myPanner->connectSource(myView);
