i have QGraphicsItemGroup used to store a group of QGraphicsLineItem ,
i want to change the pen of QGraphicsLineItem childs but the QGraphicsItemGroup does not have a such mlethod , so i did a cast from QGraphicsItemGroup to QGraphicsLineItem but the program has stopped !!

Hi,

the solution could be one of the following:

• Iterate over the list returned by childItems(), then check if the item is a QGraphicsLineItem and set Pen to it
• Create a class derived by QGraphicsLineItem and implement a method doing the above job
