Re: Two Marker Styles and SetMarkerAttributes

I have tried your proposal and created an object class MyAttMarker : public TObject, public TAttMarker {
public: MyAttMarker() : TAttMarker() { } }
After replacing the two TAttMarker in my class my MyAttMarker and drawing them in its Draw function I still get the wrong menu. Calling void SetAtt1() from the context menu displays the menu corresponding to the base class TAttLine of my object. This is somehow a weired behaviour... I have an Object TAttMarker, call one of its data members and get a menu corresponding to some totally different object, isn't it?
