L_INT pEXT_CALLBACK YourFunction(hCellWnd, nSubCellIndex, nX, nY, pBitmap, szPixelValue, pUserData)

This callback function is called every time the probe tool changes its location, thus updating its text.


L_HWND hCellWnd

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

L_INT nSubCellIndex

A zero-based index of the sub-cell where the probe tool is displayed.


A Value that represents the X position of the cursor.


A Value that represents the Y position of the cursor.


Pointer to a bitmap handle that is set in the specific sub-cell.

L_TCHAR * szPixelValue

A string that contain probe tool text. the user can update this text to display on the probe tool instead.

L_VOID *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_DispContainerSetProbeToolUpdatedCallBack.) Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
