Parameter

Description

hCellWnd

A handle to the window that represents the Medical Viewer Cell.

hMemDC

Handle to memory device context is used to paint the cell.

lpRect

Pointer to a RECT structure that contains the client coordinates of the rectangle for the user to paint in.

nCellIndex

A zero-based index of the cell in which the callback will paint.

nSubCellIndex

A zero-based index into the image list attached to the cell specified in nCellIndex. This image is the one on which the callback will paint.

pUserData

A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of L_DispContainerSetPaintCallBack.) Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

The function was successful.
