public: event EventHandler<MedicalViewerPaintInformationEventArgs^>^ PostPaint
The event handler receives an argument of type MedicalViewerPaintInformationEventArgs containing data related to this event. The following MedicalViewerPaintInformationEventArgs properties provide information specific to this event.
Property | Description |
---|---|
CellIndex | Gets the value that indicates the index of the cell that is to be painted. This value is only valid if the cell is add to the MedicalViewer. |
ClipRectangle (Inherited from System.Windows.Forms.PaintEventArgs) | Gets the rectangle in which to paint. |
Draw | Gets or sets the value that indicates whether to make the control draw the sub-cell. This is used only with the Leadtools.MedicalViewer.MedicalViewerCell.PrePaint event. |
Graphics (Inherited from System.Windows.Forms.PaintEventArgs) | Gets the graphics used to paint. |
ImageRectangle | Gets the rectangle that represents the image rectangle for the cell or sub-cell. |
SubCellIndex | Gets the value that indicates the index of the sub-cell that is to be painted. |
