I didn't try myself yet (;-)) so all bugs of this code are yours :-) class MyPickLocker : public TObject { privet: Bool_t lockMouse; TVirtualPad *lockedPad; public: MyPickLocker(Bool_t lock=kTRUE) {lockMouse = kTRUE;lockedPad= 0;} void SetMouseLock(Bool_t lock=kTRUE){ lockMouse = lock;} void SetPad(TVirtualPad *pad=0){lockedPad= pad;} void SetMouseUnLock(){ SetMouseLock(kFALSE);} Bool_t GetMouseLock(){ return lock;} virtual Int_t DistancetoPrimitive(Int_t px, Int_t py){ TVirtualPad *pad = lockedPad; if (!pad) pad = gPad; if (lockMouse && pad) { pad->SetSelected(0); return 0; } } } ; Just an idea, may be Rene will comment this.
