TGImageMap(const TGWindow *p, const TGPicture *pic) : TGPictureButton(p, pic)
 Create an image map widget.

TGImageMap(const TGWindow *p, const TString &pic) : TGPictureButton(p, 0)
 Create an image map widget.

~TGImageMap()
 Cleanup image map widget.

void AddRegion(const TGRegion &region, Int_t id)
 Add a region to the image map.

TGPopupMenu* CreatePopup(Int_t id)

TGPopupMenu* GetPopup(Int_t id)
 Return popup for regions with specified id.

Bool_t HandleMotion(Event_t *event)
 Handle mouse motion events.

Bool_t HandleDoubleClick(Event_t *event)
 Handle double click events.

Bool_t HandleButton(Event_t *event)
 Handle button events.

void SetToolTipText(const char *text, Long_t delayms)
 Set tooltip text for main region.

void SetToolTipText(Int_t id, const char *text, Long_t delayms)
 Set tooltip text for regions with specified id.

void OnMouseOver(Int_t id)
 Handle when mouse moves over region id. Emits signal
 OnMouseOver(Int_t).

void OnMouseOut(Int_t id)
 Handle when mouse moves from region id. Emits signal
 OnMouseOut(Int_t).

void RegionClicked(Int_t id)
 Handle when mouse was clicked on region id. Emits signal
 RegionClicked(Int_t).

void DoubleClicked()
