public: event EventHandler<MedicalViewerRegionCreatedEventArgs^>^ RegionCreated
The event handler receives an argument of type MedicalViewerRegionCreatedEventArgs containing data related to this event. The following MedicalViewerRegionCreatedEventArgs properties provide information specific to this event.
Property | Description |
---|---|
CellIndex | Gets a value that indicates the index of the cell that received the region update. This value is only valid if the cell is add to the MedicalViewer. |
Region | Gets the System.Drawing.Region object that has been added or changed. |
State | Gets an enumerated value that indicates the type of the region update made. |
SubCellIndex | Gets a value that indicates the index of the sub-cell that received the region update. |
